不允许Bot Framework WebChat Failure[405]方法

我们已经开发了一个聊天机器人使用微软机器人框架NodeJS模板。我们部署到Azure上。打开输出控制台时,我们看到以下错误:

var restify = require('restify');
var builder = require('botbuilder');

// Setup Restify Server
var server = restify.createServer();
server.listen(process.env.port || process.env.PORT || 3978, function () {
   console.log('%s listening to %s', server.name, server.url); 
});

// Create chat connector for communicating with the Bot Framework Service
var connector = new builder.ChatConnector({
    appId:My APP ID',
    appPassword:My APP Password
});

// Listen for messages from users 
server.post('/api/messages', connector.listen());

// Receive messages from the user and respond by echoing each message back (prefixed with 'You said:')
var bot = new builder.UniversalBot(connector, function (session) {
    session.send("You said: %s", session.message.text);
});

包.JSON

{
  "name": "",
  "version": "",
  "dependencies": {
    "botbuilder": "^3.15.0",
    "restify": "^7.2.1"
  }

控制台上的输出

我们尝试了许多解决办法,但都没有奏效。
