【问题描述】：

我有一个用 C# 编写的 Bot Framework Skill，它将消息从后端服务中继到使用 Bot Framework Composer 制作的 Consumer Bot。 Skill Bot 在单独的控制器 api/message/BackendMessage 上接收来自后端服务的消息。

[Route("api/message")]
[ApiController]
public class SkillBotBackendController : ControllerBase
{
   ...

当 Skill Bot 收到消息时，它会像这样将其发送到与 Consumer Bot 的对话中......

[HttpPost]
[Route("BackendMessage")]
public async Task PostAsync([FromBody] BackendMessage content)
{
   ...

     await _botFrameworkAdapter.ContinueConversationAsync(
         msAppId,
         conversationRec.ConversationReference,
         (ITurnContext turnContext, CancellationToken cancellationToken) =>
             turnContext.SendActivityAsync(MessageFactory.Text(backendMessage), 
                cancellationToken), default(CancellationToken));

Consumer Bot 可以看到直接来自 Skill Bot 的所有消息，但不能看到 Skill Bot 从后端服务接收到的消息。这里有一些 ngrok 条目显示...

被拒绝的消息具有与其他消息不同的 HttpContext.Request.Headers["Authorization"] 令牌，接受令牌的受众具有作曲家机器人的应用程序 ID，被拒绝令牌的受众是 https://api.botframework.com。

希望有一个简单的解释和解决方案。

感谢微软的回答：

将此添加到对话框中：

private void AddOrUpdateContinuationParameters(ITurnContext turnContext)
{
    var continuationParameters = new ContinuationParameters
    {
        ClaimsIdentity = turnContext.TurnState.Get<IIdentity>(BotAdapter.BotIdentityKey),
        ConversationReference = turnContext.Activity.GetConversationReference(),
        OAuthScope = turnContext.TurnState.Get<string>(BotAdapter.OAuthScopeKey)
    };

        _continuationParametersStore.AddOrUpdate(continuationParameters.ConversationReference.Conversation.Id, continuationParameters, (_, __) => continuationParameters);
}

更改对 ContinueConversationAsync 的调用以包含 continuationParameters：

await _botFrameworkAdapter.ContinueConversationAsync(
          (ClaimsIdentity)continuationParameters.ClaimsIdentity,
          conversationRec.ConversationReference, 
          continuationParameters.OAuthScope, 
          (ITurnContext turnContext, CancellationToken cancellationToken) => turnContext.SendActivityAsync(MessageFactory.Text(backendMessage), cancellationToken),
          default);
