Alamofire를 사용하여 매개 변수가있는 파일 업로드

Question 1

을 (를) 사용하여 파일을 업로드하려고합니다 Alamofire. 파일 ( NSUrl)을 사용하면 업로드가 잘 작동 하지만 NSData옵션 을 사용하는 방법을 알아낼 수 없습니까?

이것은 내가 테스트로 가지고있는 것입니다.

 var url:NSURL = NSURL.URLWithString("http://localhost:8080/bike.jpeg")

 var err: NSError?
 var imageData :NSData = NSData.dataWithContentsOfURL(url,options: NSDataReadingOptions.DataReadingMappedIfSafe, error: &err)

 Alamofire.upload(.POST, "http://localhost:8080/rest/service/upload/test.png", imageData)
        .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
            println(totalBytesWritten)
        }
        .responseJSON { (request, response, JSON, error) in
            println(request)
            println(response)
           println(JSON)
 }

상태 코드 415를 받고 있습니까?

또한 업로드시 추가 매개 변수를 어떻게 전송할 수 있습니까?

감사

편집하다

올바른 Content-Type을 설정하지 않았습니다.

var manager = Manager.sharedInstance
manager.session.configuration.HTTPAdditionalHeaders = ["Content-Type": "application/octet-stream"]


let imageData: NSMutableData = NSMutableData.dataWithData(UIImageJPEGRepresentation(imageTest.image, 30));

Alamofire.upload(.POST, "http://localhost:8080/rest/service/upload?attachmentName=file.jpg",  imageData)
        .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
            println(totalBytesWritten)
        }
        .responseString { (request, response, JSON, error) in
            println(request)
            println(response)
            println(JSON)
}

여전히 업로드와 함께 추가 매개 변수를 보내는 방법을 알 수 없습니다.

Question 2

다음은 대상 업로드 URL, 매개 변수 및 imageData를 요구하고 Alamofire.upload가 매개 변수와 함께 이미지를 업로드하는 데 필요한 URLRequestConvertible 및 NSData를 반환하는 간단한 함수입니다.

// this function creates the required URLRequestConvertible and NSData we need to use Alamofire.upload
func urlRequestWithComponents(urlString:String, parameters:Dictionary<String, String>, imageData:NSData) -> (URLRequestConvertible, NSData) {

    // create url request to send
    var mutableURLRequest = NSMutableURLRequest(URL: NSURL(string: urlString)!)
    mutableURLRequest.HTTPMethod = Alamofire.Method.POST.rawValue
    let boundaryConstant = "myRandomBoundary12345";
    let contentType = "multipart/form-data;boundary="+boundaryConstant
    mutableURLRequest.setValue(contentType, forHTTPHeaderField: "Content-Type")



    // create upload data to send
    let uploadData = NSMutableData()

    // add image
    uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    uploadData.appendData("Content-Disposition: form-data; name=\"file\"; filename=\"file.png\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    uploadData.appendData("Content-Type: image/png\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    uploadData.appendData(imageData)

    // add parameters
    for (key, value) in parameters {
        uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".dataUsingEncoding(NSUTF8StringEncoding)!)
    }
    uploadData.appendData("\r\n--\(boundaryConstant)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)



    // return URLRequestConvertible and NSData
    return (Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: nil).0, uploadData)
}

다음은 사용 방법의 예입니다 (요청 생성 및 보내기 참조).

// init paramters Dictionary
var parameters = [
    "task": "task",
    "variable1": "var"
]

// add addtionial parameters
parameters["userId"] = "27"
parameters["body"] = "This is the body text."

// example image data
let image = UIImage(named: "177143.jpg")
let imageData = UIImagePNGRepresentation(image)



// CREATE AND SEND REQUEST ----------

let urlRequest = urlRequestWithComponents("http://example.com/uploadText/", parameters: parameters, imageData: imageData)

Alamofire.upload(urlRequest.0, urlRequest.1)
    .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
        println("\(totalBytesWritten) / \(totalBytesExpectedToWrite)")
    }
    .responseJSON { (request, response, JSON, error) in
        println("REQUEST \(request)")
        println("RESPONSE \(response)")
        println("JSON \(JSON)")
        println("ERROR \(error)")
}

그리고 대상 URL에 대한 php 파일이 필요한 경우 (동일한 디렉토리에 'uploads'폴더 포함) :

// get picture variables
$file       = $_FILES['file']['tmp_name'];
$fileName   = $_FILES['file']['name'];
$fileType   = $_FILES['file']['type'];

// check extension
$allowedExts = array("jpg", "jpeg", "png");
$rootName = reset(explode(".", $fileName));
$extension = end(explode(".", $fileName));

// create new file name
$time = time();
$newName = $rootName.$time.'.'.$extension;

// temporarily save file
$moved = move_uploaded_file($_FILES["file"]["tmp_name"], "uploads/".$newName );
if ($moved) $path = "uploads/".$newName;

$body = $_POST['body'];
$userId = $_POST['userId'];


$time = time();
if ($moved) {
    $fullUrl = "http://antiblank.com/testPhotoUpload/".$path;
    $arrayToSend = array('status'=>'success','time'=>$time,'body'=>$body,'userId'=>$userId, "imageURL"=>$fullUrl);
} else {
    $arrayToSend = array('status'=>'FAILED','time'=>$time,'body'=>$body,'userId'=>$userId);
}

header('Content-Type:application/json');
echo json_encode($arrayToSend);

Question 3

Swift 3 & 4 및 Alamofire 4 를 통해 매개 변수 및 사용자 정의 헤더가 있는 사진 / 파일 업로드

// import Alamofire
func uploadWithAlamofire() {
  let image = UIImage(named: "bodrum")!

  // define parameters
  let parameters = [
    "hometown": "yalikavak",
    "living": "istanbul"
  ]

  Alamofire.upload(multipartFormData: { multipartFormData in
    if let imageData = UIImageJPEGRepresentation(image, 1) {
      multipartFormData.append(imageData, withName: "file", fileName: "file.png", mimeType: "image/png")
    }

    for (key, value) in parameters {
      multipartFormData.append((value?.data(using: .utf8))!, withName: key)
    }}, to: "upload_url", method: .post, headers: ["Authorization": "auth_token"],
        encodingCompletion: { encodingResult in
          switch encodingResult {
          case .success(let upload, _, _):
            upload.response { [weak self] response in
              guard let strongSelf = self else {
                return
              }
              debugPrint(response)

          case .failure(let encodingError):
            print("error:\(encodingError)")
          }
  })
}

Swift 2 및 Alamofire 3을 통해

  // import Alamofire
  func uploadWithAlamofire() {
    let image = UIImage(named: "myImage")!

    // define parameters
    let parameters = [
      "hometown": "yalikavak",
      "living": "istanbul"
    ]

    // Begin upload
    Alamofire.upload(.POST, "upload_url",
      // define your headers here
      headers: ["Authorization": "auth_token"],
      multipartFormData: { multipartFormData in

        // import image to request
        if let imageData = UIImageJPEGRepresentation(image, 1) {
          multipartFormData.appendBodyPart(data: imageData, name: "file", fileName: "myImage.png", mimeType: "image/png")
        }

        // import parameters
        for (key, value) in parameters {
          multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
        }
      }, // you can customise Threshold if you wish. This is the alamofire's default value
      encodingMemoryThreshold: Manager.MultipartFormDataEncodingMemoryThreshold,
      encodingCompletion: { encodingResult in
        switch encodingResult {
        case .Success(let upload, _, _):
          upload.responseJSON { response in
            debugPrint(response)
          }
        case .Failure(let encodingError):
          print(encodingError)
        }
    })
  }

Question 4

다음은 antiblanks 답변을 기반으로 Alamofire 3.0을 사용하는 솔루션입니다.

 let parameters = [
            "par1": "value",
            "par2": "value2"]    

 let URL = "YOUR_URL.php"

 let image = UIImage(named: "image.png")

 Alamofire.upload(.POST, URL, multipartFormData: {
                multipartFormData in

                if let _image = image {
                    if let imageData = UIImageJPEGRepresentation(_image, 0.5) {
                        multipartFormData.appendBodyPart(data: imageData, name: "file", fileName: "file.png", mimeType: "image/png")
                    }
                }

                for (key, value) in parameters {
                    multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
                }

            }, encodingCompletion: {
                encodingResult in

                switch encodingResult {
                case .Success(let upload, _, _):
                     upload.responseObject { (response: Response<UploadData, NSError>) -> Void in

                     switch response.result {
                     case .Success:
                         completionHandler?(success: true)
                     case .Failure(let error):
                         completionHandler?(success: false)
                     }

                 }
                case .Failure(let encodingError):
                    print(encodingError)
                }
        })

Question 5

Swift 2.2 Alamofire 3.3.1에 대한 EdFunke의 답변 향상

Alamofire.upload(.POST, urlString, multipartFormData: {
            multipartFormData in
            if let _image = self.profilePic.image {
                if let imageData = UIImagePNGRepresentation(_image) {
                    multipartFormData.appendBodyPart(data: imageData, name: "user_image", fileName: "file.png", mimeType: "image/png")
                }
            }
            for (key, value) in userInfo {
                multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)

                case .Failure(let encodingError):
                    print(encodingError)
                }
            }
        )

Question 6

멀티 파트 업로드는 Alamofire의 다음 (1.3.0) 릴리스에 포함될 예정입니다. 그 동안이 스레드의 정보를 사용하여 파일 업로드를 단순화하고 하나 이상의 파일과 함께 요청에 추가 매개 변수 (일반 "입력")를 포함하는 클래스를 만들었습니다. 파일이 특정 유형이거나 라우터를 사용한다고 가정하지 않습니다.

FileUploader.swift :

import Foundation
import Alamofire

private struct FileUploadInfo {
  var name:String
  var mimeType:String
  var fileName:String
  var url:NSURL?
  var data:NSData?

  init( name: String, withFileURL url: NSURL, withMimeType mimeType: String? = nil ) {
    self.name = name
    self.url = url
    self.fileName = name
    self.mimeType = "application/octet-stream"
    if mimeType != nil {
      self.mimeType = mimeType!
    }
    if let _name = url.lastPathComponent {
      fileName = _name
    }
    if mimeType == nil, let _extension = url.pathExtension {
      switch _extension.lowercaseString {

      case "jpeg", "jpg":
        self.mimeType = "image/jpeg"

      case "png":
        self.mimeType = "image/png"

      default:
        self.mimeType = "application/octet-stream"
      }
    }
  }

  init( name: String, withData data: NSData, withMimeType mimeType: String ) {
    self.name = name
    self.data = data
    self.fileName = name
    self.mimeType = mimeType
  }
}

class FileUploader {

  private var parameters = [String:String]()
  private var files = [FileUploadInfo]()
  private var headers = [String:String]()

  func setValue( value: String, forParameter parameter: String ) {
    parameters[parameter] = value
  }

  func setValue( value: String, forHeader header: String ) {
    headers[header] = value
  }

  func addParametersFrom( #map: [String:String] ) {
    for (key,value) in map {
      parameters[key] = value
    }
  }

  func addHeadersFrom( #map: [String:String] ) {
    for (key,value) in map {
      headers[key] = value
    }
  }

  func addFileURL( url: NSURL, withName name: String, withMimeType mimeType:String? = nil ) {
    files.append( FileUploadInfo( name: name, withFileURL: url, withMimeType: mimeType ) )
  }

  func addFileData( data: NSData, withName name: String, withMimeType mimeType:String = "application/octet-stream" ) {
    files.append( FileUploadInfo( name: name, withData: data, withMimeType: mimeType ) )
  }

  func uploadFile( request sourceRequest: NSURLRequest ) -> Request? {
    var request = sourceRequest.mutableCopy() as! NSMutableURLRequest
    let boundary = "FileUploader-boundary-\(arc4random())-\(arc4random())"
    request.setValue( "multipart/form-data;boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
    let data = NSMutableData()

    for (name, value) in headers {
      request.setValue(value, forHTTPHeaderField: name)
    }

    // Amazon S3 (probably others) wont take parameters after files, so we put them first        
    for (key, value) in parameters {
      data.appendData("\r\n--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
      data.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".dataUsingEncoding(NSUTF8StringEncoding)!)
    }

    for fileUploadInfo in files {
      data.appendData( "\r\n--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)! )
      data.appendData( "Content-Disposition: form-data; name=\"\(fileUploadInfo.name)\"; filename=\"\(fileUploadInfo.fileName)\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
      data.appendData( "Content-Type: \(fileUploadInfo.mimeType)\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
      if fileUploadInfo.data != nil {
        data.appendData( fileUploadInfo.data! )
      }
      else if fileUploadInfo.url != nil, let fileData = NSData(contentsOfURL: fileUploadInfo.url!) {
        data.appendData( fileData )
      }
      else { // ToDo: report error
        return nil
      }
    }

    data.appendData("\r\n--\(boundary)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

    return Alamofire.upload( request, data )
  }

}

다음과 같이 사용됩니다.

// This example uploads a file called example.png found in the app resources

let fileURL = NSBundle.mainBundle().URLForResource("example", withExtension: "png")
let fileUploader = FileUploader()
// we can add multiple files
// this would be equivalent to: <input type="file" name="myFile"/>
fileUploader.addFileURL(fileURL!, withName: "myFile")
// we can add NSData objects directly
let data = UIImage(named: "sample")
fileUploader.addFileData( UIImageJPEGRepresentation(data,0.8), withName: "mySecondFile", withMimeType: "image/jpeg" )
// we can also add multiple aditional parameters
// this would be equivalent to: <input type="hidden" name="folderName" value="sample"/>
fileUploader.setValue( "sample", forParameter: "folderName" )
// put your server URL here
var request = NSMutableURLRequest( URL: NSURL(string: "http://myserver.com/uploadFile" )! )
request.HTTPMethod = "POST"
fileUploader.uploadFile(request: request)

Question 7

@antiblank의 답변에있는 코드가 나를 위해 작동하지 않았습니다. 몇 가지 변경 사항을 적용했으며 현재 작동 중입니다.

func urlRequestWithComponents(urlString:String, parameters:NSDictionary) -> (URLRequestConvertible, NSData) {

    // create url request to send
    var mutableURLRequest = NSMutableURLRequest(URL: NSURL(string: urlString)!)
    mutableURLRequest.HTTPMethod = Alamofire.Method.POST.rawValue
    //let boundaryConstant = "myRandomBoundary12345"
    let boundaryConstant = "NET-POST-boundary-\(arc4random())-\(arc4random())"
    let contentType = "multipart/form-data;boundary="+boundaryConstant
    mutableURLRequest.setValue(contentType, forHTTPHeaderField: "Content-Type")


    // create upload data to send
    let uploadData = NSMutableData()

    // add parameters
    for (key, value) in parameters {

        uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

        if value is NetData {
            // add image
            var postData = value as NetData

            let contentDispositionString = "Content-Disposition: form-data; name=\"\(key)\";\(filenameClause)\r\n"
            let contentDispositionData = contentDispositionString.dataUsingEncoding(NSUTF8StringEncoding)
            uploadData.appendData(contentDispositionData!)

    // return URLRequestConvertible and NSData
    return (Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: nil).0, uploadData)
}

사용하다:

let docDir:AnyObject = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0]
let imagePath = docDir + "/myPic.jpg"

var imageData = NSData(contentsOfFile: imagePath, options: NSDataReadingOptions.DataReadingMappedIfSafe, error: nil)
var parameters = [
            "pic"           :NetData(nsData: imageData!, filename: "customName.jpg"),
            "otherParm"     :"Value"
        ]


    let urlRequest = self.urlRequestWithComponents("http://www.example.com/upload.php", parameters: parameters)

https://github.com/nghialv/Net/blob/master/Net/NetData.swift 의 NetData

upload.php 코드 :

<?php
// In PHP versions earlier than 4.1.0, $HTTP_POST_FILES should be used instead
// of $_FILES.

$uploaddir = 'uploads/';
// PS: custom filed name : pic
$uploadfile = $uploaddir . basename($_FILES['pic']['name']);

if (move_uploaded_file($_FILES['pic']['tmp_name'], $uploadfile)) {
   $array = array ("code" => "1", "message" => "successfully");  
} else {
   $array = array ("code" => "0", "message" => "Possible file upload attack!".$_FILES['pic']['name']); 
}

echo json_encode ( $array );

Question 8

@antiblank 및 @VincentYan 답변을 기반으로 한 더 짧은 버전입니다.

Question 9

멀티 파트 요청을 수동으로 구성하는 방법을 조언하는 다른 답변이 있지만 AFNetworking을 계속 사용하는 것이 좋습니다. Objective-C로 작성되었지만 Swift 프로젝트에서 계속 사용할 수 있습니다 ( 같은 프로젝트의 Swift 및 Objective-C 참조 ). 어쨌든 AFNetworking을 사용하여 멀티 파트 요청을 제출하는 Swift 코드는 다음과 같습니다.

let data = UIImagePNGRepresentation(image)

let manager = AFHTTPSessionManager()

manager.POST(uploadURLString, parameters: nil, constructingBodyWithBlock: { formData in
    formData.appendPartWithFileData(data, name: "image", fileName: "test.png", mimeType: "image/png")
}, success: { operation, responseObject in
    println(responseObject)
}) { operation, error in
    println(error)
}

Xcode는이 id<AFMultipartFormData>매개 변수를 인식하는 데 문제가 formData있으므로 appendPartWithFileData메소드 또는 매개 변수 의 일반적인 편집기 코드 완성을 즐기지 못하지만 컴파일하고 실행하면 제대로 작동합니다.

Question 10

요청에 콘텐츠 유형 이 누락되어 415를 받고 있습니다. 아래는 Swift 2 및 AlamoFire에 이미지 업로드에 대한 전체 소스입니다.

import UIKit
import Alamofire

class ViewController: UIViewController {

@IBOutlet var imageView: UIImageView!
@IBOutlet var btnUpload: UIButton!
override func viewDidLoad() {
    super.viewDidLoad()
}

func successDataHandler(responseData:String){

    print ("IMAGE UPLOAD SUCCESSFUL    !!!")

}

func failureDataHandler(errorData:String){

    print ("  !!!   IMAGE UPLOAD FAILURE   !!! ")

}

@IBAction func actionUpload(sender: AnyObject) {

    let URL = "http://m8coreapibeta.azurewebsites.net/api/cards/SaveImages"

    let postDataProlife:[String:AnyObject] = ["CardId":(dataCardDetail?.userId)!,"ImageType":1,"ImageData":imageView.image!]

    uplaodImageData(URL, postData: postDataProlife, successHandler: successDataHandler, failureHandler: failureDataHandler)
}

func uplaodImageData(RequestURL: String,postData:[String:AnyObject]?,successHandler: (String) -> (),failureHandler: (String) -> ()) -> () {

    let headerData:[String : String] = ["Content-Type":"application/json"]

    Alamofire.request(.POST,RequestURL, parameters: postData, encoding: .URLEncodedInURL, headers: headerData).responseString{ response in
        switch response.result {
        case .Success:
            print(response.response?.statusCode)
            successHandler(response.result.value!)
        case .Failure(let error):
            failureHandler("\(error)")
        }
    }
}
}

Question 11

아래는 신속하고 Php 코드입니다.

Swift 코드-> Apple Swift 버전 3.0.1 (swiftlang-800.0.58.6 clang-800.0.42.1) 대상 : x86_64-apple-macosx10.9

   class  func upload(jsonObject: AnyObject , files : Array<Any>? = nil  , completionHandler :  CompletionBlock? = nil ,failureHandler : FailureBlock? = nil )
{

    Alamofire.upload(multipartFormData:
        { (multipartFormData) in

            if let  filesO = files
            {
                for i in (filesO.enumerated())
                {
                    let image = UIImage(named: "\(i.element)")

                    let data = UIImageJPEGRepresentation(image!, 1)!

                    multipartFormData.append(data, withName: "imgFiles[]" , fileName: "\( NSUUID().uuidString).jpeg" , mimeType: "image/jpeg")
                  // imgFiles[] give array in Php Side
                  // imgFiles   will give string in PHP String


                }

            }


            for  (key, value)  in jsonObject as! [String : String]
            {

                 multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)

            }}          
    },
                     to:baseURL)

매개 변수 및 파일을 가져 오는 PHP 코드

여기 매개 변수는 $ _Request의 핸들입니다.

그리고 파일은 $ _File에서 처리됩니다.

$ _File data (Array, Dictionary 또는 String)의 형식은 swift side의 Request에 따라 달라집니다. Here See this line in code

multipartFormData.append (data, withName : "imgFiles []", fileName : "(NSUUID (). uuidString) .jpeg", mimeType : "image / jpeg")

PHP 측 withName : "imgFiles []"는 이름, 형식, 유형의 배열을 제공합니다.

예

"name": [ "06748B86-478E-421B-8470-6262755AC149.jpeg", "E70269E9-FB54-4BFD-B807-7E418C81540D.jpeg"], "type": [ "image / jpeg", "image / jpeg" ], "tmp_name": [ "/ tmp / phpz3UAPq", "/ tmp / phpCAPExG"], "오류": [0,0], "크기": [2779495,2067259]}

PHP 코드

 if (isset($_FILES['imgFiles']) and strlen($orderId) > 0) {

        foreach ($_FILES['imgFiles']['tmp_name'] as $key => $tmp_name) {

            $file_name = $key . $_FILES['imgFiles']['name'][$key];
            $file_size = $_FILES['imgFiles']['size'][$key];
            $file_tmp = $_FILES['imgFiles']['tmp_name'][$key];
            $file_type = $_FILES['imgFiles']['type'][$key];
 if (is_dir("$desired_dir/" . $file_name) == false) {
                //move_uploaded_file($file_tmp, "user_data/" . $file_name);
                move_uploaded_file($file_tmp, $desired_dir . "/" .
           $file_name);
            } else {         //rename the file if another one exist
                $new_dir = $desired_dir . "/" . $file_name . time();
                rename($file_tmp, $new_dir);
            }

Question 12

나는 antiblank의 대답을 가져 와서 완료 핸들러를 사용하여 하나의 함수로 모두 포장했습니다. 누군가에게 유용 할 것이라고 생각했습니다. 나는 단순히 PHP 파일 (JSON이 아님)에서 문자열 응답을 취하기 때문에 약간 '거친'한 다음 antiblank의 대답입니다.

이름은 다음과 같습니다.

let imageData = UIImagePNGRepresentation(myImageView.image)

uploadImage("http://www.example.com/image_upload.php", imageData: imageData, subdir: "images", filename: "imageID.png")
    { (req, res, str, err) -> Void in
        // do whatever you want to to for error handling and handeling success
    }

다음은 함수 자체입니다.

func uploadImage(urlToPHPFile: String, imageData: NSData, subdir: String, filename: String, completionHandler:(request:NSURLRequest, response:NSURLResponse?, responseString:String?, error: NSError?) -> ()) {

    func urlRequestWithComponents(urlString:String, parameters:Dictionary<String, String>, imageData:NSData) -> (URLRequestConvertible, NSData) {
        // create url request to send
        var mutableURLRequest = NSMutableURLRequest(URL: NSURL(string: urlString)!)
        mutableURLRequest.HTTPMethod = Method.POST.rawValue
        let boundaryConstant = "myRandomBoundary12345";
        let contentType = "multipart/form-data;boundary="+boundaryConstant
        mutableURLRequest.setValue(contentType, forHTTPHeaderField: "Content-Type")

        // create upload data to send
        let uploadData = NSMutableData()

        // add image
        uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData("Content-Disposition: form-data; name=\"file\"; filename=\"file.png\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData("Content-Type: image/png\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData(imageData)

        // add parameters
        for (key, value) in parameters {
            uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
            uploadData.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".dataUsingEncoding(NSUTF8StringEncoding)!)
        }
        uploadData.appendData("\r\n--\(boundaryConstant)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

        // return URLRequestConvertible and NSData
        return (ParameterEncoding.URL.encode(mutableURLRequest, parameters: nil).0, uploadData)
    }

    let parameters = [
        "subdir" : subdir,
        "filename": filename
    ]
    let urlRequest = urlRequestWithComponents(urlToPHPFile, parameters, imageData)

    AlamoFire.upload(urlRequest.0, urlRequest.1)
        .responseString(completionHandler: { [weak self] (req, res, str, err) -> Void in
            if let strongSelf = self {
                completionHandler(request: req, response: res, responseString: str, error: err)

            }
        }
    )
}

그리고 여기에 php 파일이 있습니다.

$subdir = $_POST['subdir'];
$filename = $_POST["filename"];

$targetPath = $subdir.'/'.$filename;

$moved = move_uploaded_file($_FILES["file"]["tmp_name"], $targetPath );
if ($moved) {
    echo "OK";
}
else {
    echo "Error: file not uploaded";
}
