请求示例

  • 4.8.0版本RocketMQ实例创建一个消费组，不允许以广播模式消费，关联代理为broker-0，最大重试次数为16。

    POST https://{endpoint}/v2/{project_id}/instances/{instance_id}/groups

{
  "name" : "consumer-group-test",
  "group_desc" : "group_description",
  "brokers" : [ "broker-0" ],
  "broadcast" : false,
  "retry_max_time" : 16
}

  • 5.x版本RocketMQ实例创建一个消费组，不允许以广播模式消费，不按序消费，最大重试次数为16。

    POST https://{endpoint}/v2/{project_id}/instances/{instance_id}/groups

{
  "name" : "consumer-group-test",
  "group_desc" : "group_description",
  "consume_orderly" : false,
  "broadcast" : false,
  "retry_max_time" : 16
}

  • 删除消费组consumer-group-test。

    POST https://{endpoint}/v2/{project_id}/instances/{instance_id}/groups?action=delete

{
  "groups" : [ "consumer-group-test" ]
}

响应示例

状态码： 200

创建消费组或批量删除消费组成功。

{
  "name" : "consumer-group-test"
}
