本例中有些引用的类与方法不做过多介绍，之后会提供完整源码下载，请自行查看。

本篇根据开发者文档-素材管理编写。请对照查看，一些传入与返回参数就不过多介绍。地址为：

接口调用请求说明

http请求方式: POST/FORM,需使用https


https://api.weixin.qq.com/cgi-bin/media/upload

?>access_token=ACCESS_TOKEN&type=TYPE

调用示例（使用curl命令，用FORM表单方式上传一个多媒体文件）：

curl -F media=@test.jpg “

https://api.weixin.qq.com/cgi-

>bin/media/upload?access_token=ACCESS_TOKEN&type=TYPE”


以上摘自官方本当，但有一处错误。上传地址应为:

http://file.api.weixin.qq.com/


即 ：

curl -F media=@test.jpg “

http://file.api.weixin.qq.com/cgi-

>bin/media/upload?access_token=ACCESS_TOKEN&type=TYPE”
