登上了这个: http://www.megaupload。 com /?d = 6CKP1MVJ
解决方案XMLHttpRequest 默认情况下自动重定向,所以你看不到302响应。您需要将 nsIHttpChannel.redirectionLimit 属性设置为零以防止它:
req.open(GET,www.megaupload/?d=6CKP1MVJ,true); req.channel.QueryInterface(Components.interfaces.nsIHttpChannel).redirectionLimit = 0; req.send(null);不是您在这里使用的链接会重定向到任何地方,但这是一般的方法。顺便说一句,而不是看重定向的响应文本,你应该看看 req.getResponseHeader(Location)。
I am trying to get real path in link megaupload but always but this dont work.
function getRealURL(){ var st = new String(""); var req = new XMLHttpRequest(); req.open("GET","www.megaupload/?d=6CKP1MVJ",true); req.send(null); req.send(null); req.onreadystatechange = function (aEvt) { if (req.readyState == 4) { if(req.status == 302){ //SUCESSO st = req.responseText; } } };//funcao element.getElementById("id").setAttribute("value", st); }i need this link: Redirect to: www534.megaupload/files/c2c36829bc392692525f5b7b3d9d81dd/Coldplay - Warning Sign.mp3
insted of this: www.megaupload/?d=6CKP1MVJ
解决方案XMLHttpRequest follows the redirect automatically by default so you don't see the 302 response. You need to set nsIHttpChannel.redirectionLimit property to zero to prevent it:
req.open("GET","www.megaupload/?d=6CKP1MVJ",true); req.channel.QueryInterface(Components.interfaces.nsIHttpChannel).redirectionLimit = 0; req.send(null);Not that the link you use here redirects anywhere but this is the general approach. Btw, instead of looking at the response text for redirects you should look at req.getResponseHeader("Location").
