[英]Initiate a message from bot to user on BotFramework
I have a bot built on BotFramework 3.5 and hosted on Azure as a WebApp. 我有一个在BotFramework 3.5上构建的机器人,并在Azure上将其作为WebApp托管。 I didn't face any problems with implementation of scenarios where the bot needs to respond to user's input.
在机器人需要响应用户输入的场景的实现中,我没有遇到任何问题。 However there is a need to teach him to start conversations by some schedule.
但是,有必要教他按一定的时间表开始对话。 To reach the goal I created a WebJob which is a simple console app basically.
为了实现这一目标,我创建了一个WebJob,它基本上是一个简单的控制台应用程序。 Here is a code used to initiate a message from bot to user:
这是用于启动从机器人到用户的消息的代码:
var botAccount = new ChannelAccount(id: from);
var userAccount = new ChannelAccount(id: to);
var conversation = new ConversationAccount(false, conversationId);
var connector = new ConnectorClient(serviceUrl);
IMessageActivity message = Activity.CreateMessageActivity();
message.From = botAccount;
message.Recipient = userAccount;
message.Conversation = conversation;
message.Text = text;
message.Locale = locale;
await connector.Conversations.SendToConversationAsync((Activity)message);
from, to, serviceUrl, conversationId
- are taken from the previous conversation, so I'd expect they are valid. from, to, serviceUrl, conversationId
从上一个对话中获取,因此我希望它们是有效的。 However on SendToConversationAsync
exception is thrown: 但是在
SendToConversationAsync
会引发异常:
System.UnauthorizedAccessException: Authorization for Microsoft App ID 3a26a4d4-f75a-4feb-b3e0-37a7fa24e5fc failed with status code Unauthorized and reason phrase 'Unauthorized' ---> System.Net.Http.HttpRequestException: Response status code does not indicate success: 401 (Unauthorized)
The app.config file contains the same values as the original bot API, including AppId and AppSecret. app.config文件包含与原始bot API相同的值,包括AppId和AppSecret。 I saw a few questions raised on the same topic, but didn't manage to find an answer.
我看到有关同一主题的几个问题,但没有找到答案。
Am I missing something? 我想念什么吗? Is it a valid approach to send messages on behalf of bot from the console app?
从控制台应用程序代表机器人发送消息是否有效?
According to your description, I followed this tutorial for getting started with the Connector and followed this tutorial for sending and Receiving Activities. 根据您的描述,我按照本教程开始使用连接器,并按照本教程进行发送和接收活动。
Based on your code, I created my console application and I could reproduce the same issue, then I found a git issue about the similar issue. 基于您的代码,我创造了我的控制台应用程序,我可以重现同样的问题,然后我发现了一个混帐问题有关类似的问题。 After some trials, I could make it work as expected on my side, you could refer to it:
经过一番试验后,我可以使它按我的预期工作,您可以参考一下:
MicrosoftAppCredentials.TrustServiceUrl("{ServiceUrl}", DateTime.Now.AddDays(7));
var account=new MicrosoftAppCredentials("MicrosoftAppIdKey", "MicrosoftAppPasswordKey");
var connector = new ConnectorClient(new Uri("{ServiceUrl}"),account);
OR 要么
Implement your DelegatingHandler 实现您的DelegatingHandler
public class MyDelegatingHandler : DelegatingHandler
{
private string _token;
public MyDelegatingHandler(string token)
{
_token = token;
}
protected override Task<HttpResponseMessage> SendAsync(
HttpRequestMessage request, CancellationToken cancellationToken)
{
request.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", _token);
return base.SendAsync(request, cancellationToken);
}
}
Then, you need to build your ConnectorClient
as follows: 然后,您需要按照以下方式构建
ConnectorClient
:
var account=new MicrosoftAppCredentials("{MicrosoftAppIdKey}", "{MicrosoftAppPasswordKey}");
var jwtToken=await account.GetTokenAsync();
var connector = new ConnectorClient(new Uri("{serviceUrl}"),handlers:new MyDelegatingHandler(jwtToken));
Here is my console application code snippet, you could refer to it: 这是我的控制台应用程序代码段,您可以参考它:
try
{
var userAccount = new ChannelAccount() { Id = "default-user", Name = "user" };
var botAccount = new ChannelAccount() { Id = "934493jn5f6f348f", Name = "console-Bot" };
string url = "{serviceUrl}";
MicrosoftAppCredentials.TrustServiceUrl(url, DateTime.Now.AddDays(7));
var account = new MicrosoftAppCredentials("{MicrosoftAppIdKey}", "{MicrosoftAppPasswordKey}");
var connector = new ConnectorClient(new Uri(url), account);
IMessageActivity message = Activity.CreateMessageActivity();
message.From = botAccount;
message.Recipient = userAccount;
message.Conversation = new ConversationAccount() { Id = "{conversationId}" };
message.Text = "Message sent from console application!!!";
message.Locale = "en-us";
var response = await connector.Conversations.SendToConversationAsync((Activity)message);
Console.WriteLine($"response:{response.Id}");
}
catch (Exception e)
{
Console.WriteLine($"exception:{e.Message}\r\n{e.StackTrace}");
}
Result 结果
尝试像这样创建新的对话:
var conversationId = await connector.Conversations.CreateDirectConversationAsync(botAccount, userAccount);
