나는 새로운 파이어 폭스 애드온을 개발하고 그 절편 모든 파이어 폭스의 네트워크 트래픽 (와 HTTP (S) 요청 http-on-modify-request)
현재 코드를 사용하면 웹 페이지 / 탭 및 기타 모든 구성 요소 (RSS 피드 업데이트, XPCOM 구성 요소의 XHR 요청, 확장, 확장 관리자 등)에서 오는 요청을 분리 할 수 있습니다.
전체 그룹뿐만 아니라 탭의 트래픽 이외의 요청을 시작하는 사람을 정확하게 식별하고 싶습니다. (RSS, XPCOM 구성 요소, 확장, 확장 관리자 등)
예 : 가상 맞춤 변수requestRequestor 에는 특정 애드온 또는 RSS 업데이트 등을 식별하는 값이 있습니다.
이 비슷한 질문을 찾았 지만 해결책이 없습니다.
전체 그룹을 식별하는 현재 코드 ( http-on-modify-request 알림을 실행하는 브라우저 가져 오기 )는 다음과 같습니다.
Components.utils.import('resource://gre/modules/Services.jsm');
Services.obs.addObserver(httpObs, 'http-on-modify-request', false);
//Services.obs.removeObserver(httpObs, 'http-on-modify-request'); //uncomment this line, or run this line when you want to remove the observer
var httpObs = {
observe: function (aSubject, aTopic, aData) {
if (aTopic == 'http-on-modify-request') {
/*start - do not edit here*/
var oHttp = aSubject.QueryInterface(Components.interfaces.nsIHttpChannel); //i used nsIHttpChannel but i guess you can use nsIChannel, im not sure why though
var interfaceRequestor = oHttp.notificationCallbacks.QueryInterface(Components.interfaces.nsIInterfaceRequestor);
//var DOMWindow = interfaceRequestor.getInterface(Components.interfaces.nsIDOMWindow); //not to be done anymore because: https://developer.mozilla.org/en-US/docs/Updating_extensions_for_Firefox_3.5#Getting_a_load_context_from_a_request //instead do the loadContext stuff below
var loadContext;
try {
loadContext = interfaceRequestor.getInterface(Components.interfaces.nsILoadContext);
} catch (ex) {
try {
loadContext = aSubject.loadGroup.notificationCallbacks.getInterface(Components.interfaces.nsILoadContext);
//in ff26 aSubject.loadGroup.notificationCallbacks was null for me, i couldnt find a situation where it wasnt null, but whenever this was null, and i knew a loadContext is supposed to be there, i found that "interfaceRequestor.getInterface(Components.interfaces.nsILoadContext);" worked fine, so im thinking in ff26 it doesnt use aSubject.loadGroup.notificationCallbacks anymore, but im not sure
} catch (ex2) {
loadContext = null;
//this is a problem i dont know why it would get here
}
}
/*end do not edit here*/
/*start - do all your edits below here*/
var url = oHttp.URI.spec; //can get url without needing loadContext
if (loadContext) {
var contentWindow = loadContext.associatedWindow; //this is the HTML window of the page that just loaded
//aDOMWindow this is the firefox window holding the tab
var aDOMWindow = contentWindow.top.QueryInterface(Ci.nsIInterfaceRequestor).getInterface(Ci.nsIWebNavigation).QueryInterface(Ci.nsIDocShellTreeItem).rootTreeItem.QueryInterface(Ci.nsIInterfaceRequestor).getInterface(Ci.nsIDOMWindow);
var gBrowser = aDOMWindow.gBrowser; //this is the gBrowser object of the firefox window this tab is in
var aTab = gBrowser._getTabForContentWindow(contentWindow.top); //this is the clickable tab xul element, the one found in the tab strip of the firefox window, aTab.linkedBrowser is same as browser var above //can stylize tab like aTab.style.backgroundColor = 'blue'; //can stylize the tab like aTab.style.fontColor = 'red';
var browser = aTab.linkedBrowser; //this is the browser within the tab //this is what the example in the previous section gives
//end getting other useful stuff
} else {
Components.utils.reportError('EXCEPTION: Load Context Not Found!!');
//this is likely no big deal as the channel proably has no associated window, ie: the channel was loading some resource. but if its an ajax call you may end up here
}
}
}
