我想使用plupload庫將文件上傳到遠程服務器。一切適用於Chrome（32.0）和IE 10使用html5運行時，但當我嘗試使用Firefox 27（html5運行時）或IE 8（html4運行時）時，出現錯誤Error #-200: HTTP Error.。Plupload跨域上傳200 http錯誤
客戶端腳本：
$(function() {
var uploader = new plupload.Uploader({
browse_button: 'browse',
url: 'https://remote.com/API/action.php',
runtimes : 'html5,flash,silverlight,html4',
flash_swf_url : './js/Moxie.swf',
silverlight_xap_url : './js/Moxie.xap'
});
uploader.init();
uploader.settings.multipart_params = {
[...]
};
// PreInit events, bound before any internal events
uploader.bind('init', function(up, info) {
console.log('[Init]', 'Info:', info, 'Features:', up.features);
alert(info['runtime']);
});
uploader.bind('Error', function(up, err) {
document.getElementById('console').innerHTML += "\nError #" + err.code + ": " + err.message;
});
document.getElementById('start-upload').onclick = function() {
uploader.start();
};
});
與Chrome的第一個請求：
Request URL:https://remote.com/API/action.php
Request Method:OPTIONS
Status Code:200 OK
與Chrome的第二個請求：
Request URL:https://remote.com/API/action.php
Request Method:POST
Status Code:200 OK

if (!empty($_FILES)) {
與Firefox的響應與該OPTIONS方法的要求是空的，並且沒有以下POST請求。
下面是Firefox的標題：
我想不通爲什麼它不與Firefox和IE8工作。
感謝您的幫助。
我剛剛嘗試過使用Flash運行時：它與Chrome和IE 10一起使用，但與Firefox和IE8不兼容。奇怪的是，該alert(info['runtime']);不再出現，但沒有JavaScript錯誤控制檯...
我不確定，但我認爲某些瀏覽器可能會向服務器發送預檢檢查請求以檢查標題（我對於確切的細節有點模糊），可能會在此處提供一些信息：http：// stackoverflow.com/questions/13614802/jquery-ajax-request-called-twice-and-the-first-request-does-not-send-token-in-he –
