Bot Framework v3.0上带有Slack连接器的ReplyToActivityAsync引发异常 [英] ReplyToActivityAsync throwing exception with Slack connector on Bot Framework v3.0

问题描述

我创建了一个bot v3.0项目并将其连接到Slack和Skype. Skype连接器效果很好，但是我在使用Slack连接器时遇到了麻烦.

I have created a bot v3.0 project and connected it to both Slack and Skype. The Skype connector works great, but I am having trouble with the Slack connector.

这是默认项目中的我的Post处理程序.

Here is my Post handler from the default project.

public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
{
    if (activity.Type == ActivityTypes.Message)
    {
        ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl));

        // calculate something for us to return
        int length = (activity.Text ?? string.Empty).Length;

        // return our reply to the user
        Activity reply = activity.CreateReply($"You sent {activity.Text} which was {length} characters");
        await connector.Conversations.ReplyToActivityAsync(reply);
    }
    else
    {
        HandleSystemMessage(activity);
    }

    var response = Request.CreateResponse(HttpStatusCode.OK);
    return response;
}

当我从Slack发送一条消息时，它被传递到后处理程序，并且活动对象看起来还不错.我可以看到松弛的数据，包括邮件，收件人等.然后调用:

When I send a message from Slack, it is delivered to the post handler and the activity object looks fine. I can see the slack data including the message, recipient, etc. Then the call to:

await connector.Conversations.ReplyToActivityAsync(reply);

抛出一条异常，消息为无法反序列化响应"，并抛出内部异常，错误为解析值时出现意外字符:< ;.路径"，第0行，位置0."

throws an exception with the message "Unable to deserialize the response" and an inner exception with the error "Unexpected character encountered while parsing value: <. Path '', line 0, position 0."

其他几点.

1. 此代码也适用于Skype.
2. 我成功地使用了Bot Framework v1项目中的这个松弛机器人.

对于Slack频道，我需要做些不同的事情吗?

Is there something that I need to do differently for the Slack channel?

谢谢！

更新: 此问题发生在Microsoft.Bot.Builder v3.0.0中，并且已在Microsoft.Bot.Builder v3.0.1中修复.现在，我可以通过Slack和Skype与我的机器人正确通信了.

UPDATE: This issue occurred in Microsoft.Bot.Builder v3.0.0 and it is fixed in Microsoft.Bot.Builder v3.0.1. I am now able to communicate with my bot properly from both Slack and Skype.
