Bot Framework bot 无法在没有提示的情况下在 Microsoft Teams 频道中 post

Question

我有一个使用 Microsoft Bot Framework 构建的机器人，发布在 Azure App Service 中，我想 post 在 Microsoft Teams 频道中响应 POST 调用。我在继承自 ApiController 的 WebhookAPIController class 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 获取服务 URL 和频道 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，没有消息被 posted 并且我收到此错误消息作为响应：

{
    "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，如果我先在频道中 @-mention 机器人，POST 会调用 returns 200 并且机器人会在频道中 posts。有没有一种方法可以将我的机器人配置为能够 post 在频道中而不被提及？

Answer 1

尝试向 ConnectorClient 构造函数添加凭据：

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 );

Answer 2

感谢，让它正常工作。在调用 CreateConversationAsync() 之前将以下代码添加到 CreateChannelConversation()：

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