Socket实现发送Http请求上传文件

最近在实现发送反馈的功能，需要自己封装实现Http上传，首先需要知道上传表单数据的格式，下面是我获取的请求格式

Remote Address:127.0.0.1:80

上传文件到服务器最主要的是按上面的请求格式封装好，然后再去发送请求数据

请求头的格式：

POST /test/upload.php HTTP/1.1
Host: 127.0.0.1
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
Accept-Encoding: gzip, deflate
Connection: keep-alive
Referer: http://127.0.0.1/test/form.html
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.101 Safari/537.36
Content-Type: multipart/form-data; boundary=----AOMEIBackupForBoundary8oZtvmhb0OlCkGLo
Content-Length: 321530605
