javascript - Bot Framework v4 - 发起与用户的聊天(主动消息)

Question

我想在用户尚未与机器人聊天的情况下开始与他对话。

当用户将机器人应用程序安装为 mentionned here 时，我将继续获取 conversationId

这里是我如何使用processActivity事件捕获reference和serviceUrl

然后我使用continueConversation + reference

const {
    BotFrameworkAdapter,
} = require('botbuilder');
const adapter = new BotFrameworkAdapter({
    appId: "xxxx",
    appPassword: "xxxxy"
})
module.exports = async function(context, req) {
    console.log(adapter);
    try {

        adapter.processActivity(req, context.res, async (turnContext) => {
            const reference = turnContext.activity.conversation.id
            const serviceUrl = turnContext.activity.serviceUrl

            await adapter.continueConversation(reference, async (turnContext) => {
                try {
                    await turnContext.sendActivity("this is proacive message");

                } catch (e) {
                    console.log(e)
                }
            });

        });
    } catch (e) {
        console.log(e)
    }
    return;
};

我收到此错误

Error: BotFrameworkAdapter.sendActivity(): missing serviceUrl.

我已经检查了 turnContext.activity 值。我得到: {"type":"event","name":"continueConversation"}" 所有其他值均未定义(serviceUrl 也是如此)

我注意到 adapter.processActivity 中的 turnContext.activity 与 adapter.continueConversation 中的不同，并且具有所有 serviceUrl 和 conversationId

如何编辑此代码示例以便能够向用户发送主动消息？

Answer 1

如果您将 const 引用用于 BotFrameworkAdapter.continueConversation()，则它必须是 ConversationReference 而不仅仅是 Id。

可以使用以下方式检索 ConversationReference:

const reference = TurnContext.getConversationReference(turnContext.activity);
