1 上传临时素材API
素材上传得到media_id，该media_id仅三天内有效
media_id在同一企业内应用之间可以共享
请求方式：POST（HTTPS）
请求地址：https://qyapi.weixin.qq.com/cgi-bin/media/uploadaccess_token=ACCESS_TOKEN&type=TYPE
使用multipart/form-data POST上传文件， 文件标识名为”media”参数说明：
| 参数 | 必须 | 说明 |
| access_token | 是 | 调用接口凭证 |
| type | 是 | 媒体文件类型，分别有图片（image）、语音（voice）、视频（video），普通文件（file） |
POST的请求包中，form-data中媒体文件标识，应包含有 filename、filelength、content-type等信息
filename标识文件展示的名称。比如，使用该media_id发消息时，展示的文件名由该字段控制
请求示例：
POST https://qyapi.weixin.qq.com/cgi-bin/media/upload?access_token=accesstoken001&type=file HTTP/1.1Content-Type: multipart/form-data; boundary=-------------------------acebdf13572468 Content-Length: 220---------------------------acebdf13572468 Content-Disposition: form-data; name="media";filename="wework.txt"; filelength=6 Content-Type: application/octet-streammytext---------------------------acebdf13572468--
