Youtube api youtube-v3-api频道列表错误

当我使用页面上的测试表单获取上传ID时，我没有在输出中获取上传ID信息

用于生成此请求的命令是

GET https://www.googleapis.com/youtube/v3/channels?part=contentDetails&forUsername=StraconisChannel

让我感到困惑的是，我正在做的事情与我所遵循的教程所建议的一样，我唯一要做的是更改频道名称，并改用我的频道名称。他的输出如下所示：

   }
  }
 ]
}

用于其结果的请求：

GET https://www.googleapis.com/youtube/v3/channels?part=contentDetails&forUsername=techguyweb

我使用OAuth 2.0激活了授权，所以我不确定问题出在哪里

编辑

一条评论说，因为这是我的youtube用户名，而不是我的google plus帐户名。我忘了把这个也放在提供的信息里。这是同样的结果

如果指定通道ID而不是通道名称，它将返回正确的响应（我是通过HTTP请求获得信息的，但它的工作方式应该与您尝试获取响应的方式相同）

---

确保您已验证YouTube频道并将频道连接到Google+页面或个人资料。
