Request syntax

An HTTP request uses the following syntax to report custom events: 
POST /event/custom/upload HTTP/1.1 
Authorization:<AuthorizationString>
Content-Length:<Content Length>
Content-MD5:<Content MD5>
Content-Type:application/json
Date:<GMT Date>
Host:metrichub-cms-cn-hangzhou.aliyuncs.com
x-cms-signature:hmac-sha1
x-cms-api-version:1.0
x-cms-ip:30.27.XX.XX
User-Agent:cms-java-sdk-v-1.0
[{"content":"EventContent","groupId":GroupId,"name":"EventName","time":"20171023T144439.948+0800"}]
