标签： c# google-api youtube-data-api google-api-dotnet-client google-data-api

我使用console创建了C#个应用程序。 从本地驱动器到upload Video youtube。 我使用this link在google api中创建了新应用。 我还使用packages安装了所有必需的nuget。 当我运行我的应用程序时，我收到错误“拒绝访问”我无法找到问题。

我在Task Run()方法中遇到错误。

    }
  }
}

我是否需要将'user'参数传递给gmail用户名？

使用C＃（console / web）的任何工作示例？

帮助感谢。

我讨厌.NET而且我已经和它斗争了好几个星期。我遇到的一些问题;

  1. 一对错误的API密钥，他们只是没有工作。我想这是一个随机的错误。
  2. 我还有一些我从Youtube上下载的不会上传的MP4，在创作工作室中他们会说＆＃34;上传失败：无法处理文件＆＃34;我通过尝试在youTube界面上传它们来确定这一点。 （不是通过API）
  3. 异步与同步导致了许多我不理解的问题。

    4. 我想改进此代码以提供实际的上传状态/反馈，但我认为需要在客户端完成。我不是很擅长C＃/。NET

    更新这是我的反馈代码，来自服务器＆amp;客户方 - https://stackoverflow.com/a/49516167/3790921

答案 1 :(得分：0)

我对您的代码进行了一些小的更改，最好先让Oauth2的初始示例工作。很难说你为何拒绝接入。这是我改变了。

  1. ＆＃34;用户＆＃34;我已更改为Environment.UserName，这样您的凭据名称将是当前登录用户的名称。
  2. 我已经更改了FileDataStore的位置我并不确定您使用的代码是否正常工作。我将把凭证存储在当前工作目录的新目录中。

    3. 有关用户参数的信息，它仅用于在提交给FileDataStore的目录中创建凭据。

      

    Google.Apis.Auth.OAuth2.Responses.TokenResponse-lilaw

    我的登录用户名是lilaw，您可以通过这种方式为每个用户提供凭据文件。因为这是一个并不重要的控制台应用程序。

    如果这不能开箱即用，你应该检查一下：

    1. 在Google开发者控制台上创建客户端时，请确保它是其他类型。您无法使用具有浏览器凭据的控制台应用程序，并且您无法将YouTube API与服务帐户一起使用。
    2. 请注意，基于YouTube API频道，因此当您登录时选择频道，您只能访问该频道。

      3. 提示：如果要注销当前用户或强制它再次登录。只需将Environment.UserName更改为其他强制它再次登录的内容

      我已经测试了它运行的代码：

答案 2 :(得分：-1)

以下代码示例调用API的playlistItems.list方法，以检索上传到与请求关联的频道的视频列表。该代码还调用channels.list方法，将mine参数设置为true，以检索标识频道上传视频的播放列表ID。
