我正在尝试从嵌入式网络聊天发送和接收事件，该网络聊天遵循本示例中的网站代码 https://github.com/ryanvolum/backChannelBot并且机器人执行来自 Bot framework get the ServiceUrl of embedded chat control page 的代码由 ezequiel 回答

这是我的设置中的样子index.html

<!DOCTYPE html>
<!-- 
NOTE: This sample requires a bot which can send and receive specific event messages. Follow the instructions on 
https://github.com/ryanvolum/backChannelBot to deploy such a bot. 
This is a sample HTML file which shows how to embed an instance of WebChat which listens for event activities. For the sake
of demonstration it specifically listens for events of name "changeBackground". Using the backChannelBot sample 
our page can listen for events of name "changeBackground" and send events of name "buttonClicked". This 
highlights the ability for a bot to communicate with a page that embeds the bot through WebChat. 

1. Build the project: "npm run build"
2. Start a web server: "npm run start"
3. Aim your browser at "http://localhost:8000/samples/backchannel?[parameters as listed below]"
For ease of testing, several parameters can be set in the query string:
    * s = Direct Line secret, or
    * t = Direct Line token (obtained by calling Direct Line's Generate Token)
    * domain = optionally, the URL of an alternate Direct Line endpoint
    * webSocket = set to 'true' to use WebSocket to receive messages (currently defaults to false)
    * userid, username = id (and optionally name) of bot user
    * botid, botname = id (and optionally name) of bot

我已经测试了发送消息事件，效果很好，但是在收到消息后尝试将事件从机器人发送到网页或从网页发送到机器人没有任何作用。

网页上说 BotChat 在这两个地方都没有定义，但我不确定为什么

var params = BotChat.queryParams(location.search);

和

var botConnection = new BotChat.DirectLine({

在 index.html 中

我所有的应用程序 secret /ID 和直线 secret 都已添加。我觉得问题可能出在我如何在 index.html 中添加我的 secret 和 url，但我不确定我将如何设置它

最佳答案

我重新创建了您的项目并将其发布到 Azure:http://QuickBackChannelEventTest.AzureWebsites.net/index.html

我在 GitHub 上发布了代码.您需要更改 web.config 中的 MicrosoftAppId 和 MicrosoftAppPassword，并将机器人的 Direct Line 密码添加到 index.html 页面的 BotChat.DirectLine 创建中:

var botConnection = new BotChat.DirectLine({
            secret: '**DIRECT_LINE_SECRET**',//params['mysecret'],
            //token: params['t'],
            //domain: params['ngroktunneledurl.com/api/messages'],
            webSocket: params['webSocket'] && params['webSocket'] === "true" // defaults to true
    });

我还添加了一个名为 TestStandAlone 的文件夹，其中仅包含 Index.html、botchat.css 和 botchat.js:https://github.com/EricDahlvang/BackChannelEventTest/tree/master/TestStandalone一旦设置了机器人的 Direct Line secret ，这就会按预期工作。
