时间:2024-09-19 21:20:28

操作步骤

  1. 获取用户Token,用于调用媒体直播接口时进行认证鉴权。

    详细信息请参见构造请求。以“华北-北京四”为示例,若您需要调用其它区域的媒体直播接口,请替换成对应区域的 IAM 终端节点。

    POST https://iam.cn-north-4.myhuaweicloud.com/v3/auth/tokens
    Content-Type: application/json
    {
      "auth": {
        "identity": {
          "methods": [
            "password"
          ],
          "password": {
            "user": {
              "name": "username", 
              "password": "password", 
              "domain": {
                "name": "domainname" 
              }
            }
          }
        },
        "scope": {
          "project": {
             "name": "projectname"      
     }
        }
      }
    }
    图1所示,红框中的信息为获取用户Token。

  2. 选择POST请求方法,并输入请求URI。

    POST https://live.cn-north-4.myhuaweicloud.com/v1/{project_id}/ott/channels
    “live.cn-north-4.myhuaweicloud.com”为媒体直播服务的终端节点,您可以在终端节点中获取。

    调用IAM接口的区域需与调用媒体直播接口的区域一致,如调用“cn-north-4”区域的IAM接口获取用户Token,则该Token仅能用于调用“cn-north-4”区域媒体直播接口的鉴权。

  3. 在请求消息头中增加“X-Auth-Token”,值设置为1中获取的用户Token。
  4. 在请求消息体中传入如下所示的参数,具体参数说明可参考新建OTT频道接口。
