我想使用 plupload 库将文件上传到远程服务器。使用 html5 运行时的 Chrome (32.0) 和 IE 10 一切正常，但当我尝试使用 Firefox 27（html5 运行时）或 IE 8（html4 运行时）时，出现错误Error #-200: HTTP Error..
客户端脚本：
$(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();
};
});
Chrome 的第一个请求：
Request URL:https://remote.com/API/action.php
Request Method:OPTIONS
Status Code:200 OK
Chrome 的第二个请求：
Request URL:https://remote.com/API/action.php
Request Method:POST
Status Code:200 OK

if (!empty($_FILES)) {
对于 Firefox，对请求的响应是OPTIONS方法为空并且没有以下内容POST要求。
以下是 Firefox 的标头：
我不明白为什么它不能在 Firefox 和 IE8 上运行。
感谢您的帮助。
[编辑] 我刚刚尝试过 flash 运行时：它适用于 Chrome 和 IE 10，但不适用于 Firefox 和 IE8。奇怪的是，alert(info['runtime']);没有出现，但控制台中没有 javascript 错误...
