我有一个使用 Microsoft Bot Framework 构建的机器人，在 Azure App Service 中发布，我想在 Microsoft Teams 频道中发布该机器人以响应 POST 调用。我在继承自 ApiController 的 WebhookAPIController 类中有以下内容：

[HttpPost]
[Route("api/WebhookAPI")]
public async Task<HttpResponseMessage> RespondToWebhook([FromBody] PostTestModel value)
{
    try
    {
        await CreateChannelConversation(value.text);
        var resp = new HttpResponseMessage(HttpStatusCode.OK);
        return resp;
    }
    catch (Exception ex)
    {
        return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ex);
    }            
}

private async Task CreateChannelConversation(string value)
{
    var connector = new ConnectorClient(new Uri(System.Configuration.ConfigurationManager.AppSettings["serviceUrl"]));
    var channelData = new Dictionary<string, string>();
    channelData["teamsChannelId"] = System.Configuration.ConfigurationManager.AppSettings["ChannelId"];
    IMessageActivity newMessage = Activity.CreateMessageActivity();
    newMessage.Type = ActivityTypes.Message;
    newMessage.Text = "Hello channel.";
    ConversationParameters conversationParams = new ConversationParameters(
        isGroup: true,
        bot: null,
        members: null,
        topicName: "Test Conversation",
        activity: (Activity)newMessage,
        channelData: channelData);
    var result = await connector.Conversations.CreateConversationAsync(conversationParams);
}

此代码从 AppSettings 中获取服务 URL 和 Channel ID；据我所知，给定 Teams 频道的频道 ID 永远不会改变。但是，当我对 (bot URL)/api/WebhookAPI 进行 POST 调用时，没有发布任何消息，并且我收到以下错误消息作为响应：

{
    "message": "An error has occurred.",
    "exceptionMessage": "Authorization for Microsoft App ID [ID omitted] failed with status code Unauthorized and reason phrase 'Unauthorized'",
    "exceptionType": "System.UnauthorizedAccessException",
    "stackTrace": "   at Microsoft.Bot.Connector.JwtTokenRefresher.<SendAsync>d__2.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at System.Runtime.CompilerServices.TaskAwaiter.ValidateEnd(Task task)\r\n   at Microsoft.Bot.Connector.Conversations.<CreateConversationWithHttpMessagesAsync>d__5.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at Microsoft.Bot.Connector.ConversationsExtensions.<CreateConversationAsync>d__1.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at WebhookTestBot.Controllers.WebhookAPIController.<CreateChannelConversation>d__2.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at WebhookTestBot.Controllers.WebhookAPIController.<RespondToWebhook>d__1.MoveNext()",
    "innerException": {
    "message": "An error has occurred.",
    "exceptionMessage": "Response status code does not indicate success: 401 (Unauthorized).",
    "exceptionType": "System.Net.Http.HttpRequestException",
    "stackTrace": "   at System.Net.Http.HttpResponseMessage.EnsureSuccessStatusCode()\r\n   at Microsoft.Bot.Connector.JwtTokenRefresher.<SendAsync>d__2.MoveNext()"
}

但是，如果我首先@-提及频道中的机器人，则 POST 调用返回 200 并且机器人在频道中发布。有没有办法可以将我的机器人配置为能够在频道中发布而不被提及？

得到它的工作，感谢这个答案。在调用 CreateConversationAsync() 之前，将以下代码添加到 CreateChannelConversation()：

MicrosoftAppCredentials.TrustServiceUrl(ConfigurationManager.AppSettings["serviceUrl"], DateTime.MaxValue);

尝试将凭据添加到 ConnectorClient 构造函数：

string appId = ConfigurationManager.AppSettings["MicrosoftAppId"];
string appPassword = ConfigurationManager.AppSettings["MicrosoftAppPassword"];
var appCredentials = new MicrosoftAppCredentials(appId, appPassword);
var connector = new ConnectorClient(new Uri(ConfigurationManager.AppSettings["serviceUrl"]), appCredentials );

所以你对 serviceUrl 和 ChannelID 都进行了硬编码？当您@提及它时，频道 ID 是否与机器人收到的内容匹配？它应该看起来像这样：“19:693ecdb923ac4458a5c23661b505fc84@thread.skype” 另请注意： teamChannelId 将来会被弃用，因此您应该改为更改为 channelData.channel.id。我将更新 MSDN 上的示例代码。

无论如何，假设硬编码值与您所在的频道匹配，您的代码应该可以工作，并且可以在我的测试用例中工作。

你说你首先@提及机器人并且它有效。你能解释一下你的测试用例吗？
