【问题描述】：

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,
            "[e-mail]", 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 = "[e-mail]", 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.

【参考方案1】：

根据this 判断，您的范围可能应该设置为：

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

不要忘记删除之前生成的带有旧范围的 token.json。

【讨论】：

我也检查过，但它显示“错误 400：invalid_scope”
