The request content is split and encoded, therefore it is far from easy deal with it.
请求内容被拆分和编码，因此处理起来远非易事。
I used Apache Commons FileUploadyears ago to process this kind of request (e.i. multipart), this library simplified the process greatly.
多年前我使用Apache Commons FileUpload来处理这种请求（ei multipart），这个库大大简化了这个过程。
In the getting startedsection you could find several examples.
在入门部分，您可以找到几个示例。

You need a http parser to read the message body.
