NotifyContentFormat - Message Service - Alibaba Cloud Documentation Center

When you send a message from Message Service (MNS) to an endpoint, you can use the NotifyContentFormat parameter to specify the format of the message body. Valid values: XML, JSON, and SIMPLIFIED.

XML

If you set the NotifyContentFormat parameter to XML, the message body contains the message content and related parameters.
This format is supported by HTTP endpoints and queue endpoints.

Example:

<?xml version="1.0" encoding="utf-8"?>
    <Notification xlmns="http://mns.aliyuncs.com/doc/v1/">
        <TopicOwner>TopicOwner</TopicOwner>
        <TopicName>TopicName</TopicName>
        <Subscriber>Subscriber</Subscriber>
        <SubscriptionName>SubscriptionName</SubscriptionName>
        <MessageId>6CC4D900CA59A2CD-1-15180534A8F-20000****</MessageId>
        <Message>{1:"a", 2:"b"}</Message>
        <MessageMD5>F1E92841751D795AB325861034B5****</MessageMD5>
        <MessageTag>important</MessageTag>
