Enum Constant Summary

Enum Constants
Enum Constant and Description
`EVENT_STREAM` text/event-stream编码
`FORM_URLENCODED` 标准表单编码，当action为get时候，浏览器用x-www-form-urlencoded的编码方式把form数据转换成一个字串（name1=value1&name2=value2…）
`JSON` Rest请求JSON编码
`MULTIPART` 文件上传编码，浏览器会把整个表单以控件为单位分割，并为每个部分加上Content-Disposition，并加上分割符(boundary)
`OCTET_STREAM` application/octet-stream编码
`TEXT_HTML` text/html编码
`TEXT_PLAIN` text/plain编码
`TEXT_XML` Rest请求text/xml编码
