在使用swfupload时出现2038错误

Question

我服务器使用的是nginx+apache+php nginx在前端代理后端apache。网站主要做的是教育网站，提供在线视频播放功能。视频由会员自己上传，使用的上传工具为swfupload，但现有遇到个问题。上会员在上传视频的时候总是出现2038错误，在网上查了相关的资料也按上面的做了相应的修改可是问题依然存在。

Answer 1

你说的也有一定的道理，不过我看youku他上传比较稳定。我不知道这个是否可以在服务器上实现。

Answer 2

上传限速，需要从上传的途径入手，基于Web传统模式是不太可能限制的了的。

如果要限速，就必须自己开发浏览器插件来实现。

中国的互联网环境，家用环境的宽带，上行基本上都很不高。

Answer 3

嗯，谢谢你的提议。我去看一下这个插件。

Answer 4

最好别用swfupload了，有xss漏洞，而且已经停止更新很多年。

推荐转用plupload，支持基于HTML5模式，很好的解决了手机平台的兼容性问题。而且他针对xss的bug修复过。

国外很多的CMS系统都转用plupload了，如Wordpress就是。

而且，plupload的核心库和事件机制，很简单，十分容易使用，也容易嵌入到别的JS框架中，如我尝试过嵌入到ExtJS中使用。

这个我swfupload的主配置：
