Request syntax

An HTTP request for reporting custom events is in the following syntax:
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"}]

Request parameters

The following tables describe the headers and parameters in an HTTP request for reporting custom events.
  • Request headers
    Header Type Description

    Example: metrichub-cms-cn-hangzhou.aliyuncs.com.

    x-cms-api-version string The version of the API. Set the value to 1.0.
    x-cms-signature string The signature algorithm to use. CloudMonitor only supports the HMAC-SHA1 signature algorithm. For more information, see Does CloudMonitor support the HMAC-SHA1 signature algorithm and how do I use it?.
    x-cms-ip string The IP address of the host that reports the custom events.
    User-Agent String The description of the client.
