对基于样本的java服务器堆栈使用Fineuploader 5.0.3。
所有上传内容在Firefox，Chrome，IE 10及更高版本中都能正常运行。这似乎只发生在IE 9或更低版本中。我已经在不同环境中的多台机器上进行了测试，结果相同。
以下是来自IE9会话的调试日志：
[Fine Uploader 5.0.3] Received 1 files or inputs.

非常感谢帮助。

这似乎是5.0.0中的回归。我已提交a bug in the project's issue tracker并已安排修复v5.0.5。
快速解决方法是更改此行：
response = handler._parseJsonResponse(fileId, message),
到此：
response = qq.parseJson(message);
在源头。但是，更好的长期修复（我们应该将其纳入即将发布的修补程序版本）涉及转换the commit where we moved around the function that delegates to qq.parseJson for form-based uploads。
