DirectLineJS 接收机器人回复的副本

DirectLineJS receiving copies of Bot replies

我正在使用 DirectLineJS 通过网站从自定义网络聊天进行交流。我使用的是 Microsoft github https://github.com/Microsoft/BotFramework-DirectLineJS

发布的格式

我的实现方式是

var directLine;
    directLine= new DirectLine.DirectLine({
        secret: "My_DirectLine_Secret",
    });

    function sendReceiveActivity(msg) {
        document.getElementById("inputtext").value = "";
        conversation.innerHTML = conversation.innerHTML + "ME - " + msg + "<br/><br/>";

        directLine.postActivity({
            from: { id: 'myUserId', name: 'myUserName' }, // required (from.name is optional)
            type: 'message',
            text: msg
        }).subscribe(
            id => console.log("Posted activity, assigned ID ", id),
            error => console.log("Error posting activity", error)
            );

        directLine.activity$
            .filter(activity => activity.type === 'message' && activity.from.id === 'mybot')
            .subscribe(
            message => console.log(message)"
            );
    }

每当我开始阅读消息时,每条消息的副本数量都会增加一个,因此我的网站将经历这个循环:

我 - 向机器人发送消息

BotReply - 消息 1

我 - 向机器人发送一些消息

BotReply - 消息 2

BotReply - 消息 2

我 - 一些消息

BotReply - 消息 3

BotReply - 消息 3

BotReply - 消息 3

等等

我从机器人收到的响应 ID 对于重复消息也没有增加,所以说消息 3 的 ID = 00005,每个 BotReply - 消息 3 的 ID = 00005,但消息 4 的 ID = 00007

在我实际的 bot 中,我使用 await context.PostAsync("Some mesage"); 发送消息,仅此而已

我怎样做才能将消息回复减少到只收到一个?

尽管我将我的消息过滤为来自 "mybot"

,但文档指出 "Direct Line will helpfully send your client a copy of every sent activity, so a common pattern is to filter incoming messages on from:"

如果不查看其余代码,很难准确确定发生了什么。但是,每次发送消息时,您似乎都在订阅接收消息。请尝试更改您的代码,以便您只订阅一次:

var directLine = new DirectLine.DirectLine({
        secret: "My_DirectLine_Secret",
    });

directLine.activity$
          .filter(activity => activity.type === 'message' && activity.from.id === 'mybot')
          .subscribe(
            message => console.log(message)
            );

    function sendReceiveActivity(msg) {
        document.getElementById("inputtext").value = "";
        conversation.innerHTML = conversation.innerHTML + "ME - " + msg + "<br/><br/>";

        directLine.postActivity({
            from: { id: 'myUserId', name: 'myUserName' }, // required (from.name is optional)
            type: 'message',
            text: msg
        }).subscribe(
            id => console.log("Posted activity, assigned ID ", id),
            error => console.log("Error posting activity", error)
            );
    }
