c# - 如何使用 C# 向谷歌聊天室发布消息？ (**错误** : Request had insufficient authentication scopes)

Question

目前我正在尝试从 C# 向 Google 聊天室发送消息，尝试使用以下代码进行身份验证

    UserCredential credential;
    var jsonPath = "";
    jsonPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "client_secrets.json");
    //using (var stream = new FileStream(jsonPath, FileMode.Open, FileAccess.Read))

    using (var stream = new FileStream(jsonPath, FileMode.Open, FileAccess.Read))
    {
        string[] scopes = new[] { "https://www.googleapis.com/auth/chat"};
        credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
            GoogleClientSecrets.Load(stream).Secrets,
             scopes,
            "admin@XXXX.XX", CancellationToken.None, new FileDataStore("C:\\AlexaHangout\\Google.Hangout.Auth.Store")).Result;
    }

    // Create the service.

    var service = new HangoutsChatService(new BaseClientService.Initializer()
    {
        HttpClientInitializer = credential,
        ApplicationName = "VSAHangout",

    })


    Message msg = new Message();
    msg.Text = "Hi USER";
    msg.Sender = new User() { DisplayName = "Test", Name = "admin@XXXXX.XX", ETag = "12345", Type = "BOT" };
    msg.Space = new Space() { Name = "spaces/XXXXXXXX", DisplayName = "ViSev" }

    SpacesResource.MessagesResource.CreateRequest req = new SpacesResource.MessagesResource(service).Create(msg, "spaces/XXXXXXX");
    var result = req.Execute();

身份验证工作正常，但是当我尝试发送消息时出现以下错误。

{"ClassName":"Google.GoogleApiException","Message":"Google.Apis.Requests.RequestError\r\nRequest had insufficient authentication scopes.

由 this 判断也许您的范围应该设置为:

string[] scopes = new[] { "https://www.googleapis.com/auth/chat.bot"};

不要忘记使用旧范围删除先前生成的 token.json。
