查询通道列表
功能介绍
本接口用户查询当前租户创建的所有通道。
查询时,需要指定从哪个通道开始返回通道列表和单次请求需要返回的最大数量。
调用方法
请参见如何调用API。
URI
GET /v2/{project_id}/streams
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
project_id |
是 |
String |
项目ID。 |
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
limit |
否 |
Integer |
单次请求返回通道列表的最大数量。 最小值:1 最大值:100 缺省值:10 |
start_stream_name |
否 |
String |
从该通道开始返回通道列表,返回的通道列表不包括此通道名称。如果需要分页查询,第一页查询时不传该字段。返回结果has_more_streams为true时,进行下一页查询,start_stream_name传入第一页查询结果的最后一条通道名称。 |
请求参数
