node.js - Twilio 函数 : Sending WhatsApp message when incoming call is received

Question

我想使用 Twilio functions 在接到电话时运行我的操作。

简单的任务: 当我接到 twilio 号码上的电话时，我想转接电话并向 Whatsapp 号码发送消息以通知来电。

Twilio 网站上有一个类似的例子: Improve this question

但我无法让它与 WhatsApp 一起使用。 它仅适用于短信，但是当我用 to 数字替换 from 和 whatsapp:+01234567890 参数时，我没有收到任何消息。

我发布了一种方法，用我的 Twilio WhatsApp 沙箱进行了测试，它有效。

/**
 *  This Function will forward a call to another phone number.
 *  It will send a WhatsApp message before doing that. 
 */

exports.handler = function (context, event, callback) {

    let fromNumber = event.From; // number which called our Twilio number  
    let recipientNumber = '+10000000001'; // number where the call will be forwarded

    let client = context.getTwilioClient();

    client.messages
        .create({
            from: 'whatsapp:+10000000002', // Twilio's WhatsApp sandbox number
            body: `Call from ${fromNumber}, forwarded to ${recipientNumber}.`,
            to: 'whatsapp:+10000000003' // WhatsApp number registered with sandbox
        })
        .then(function (message) {
            console.log(message.sid);
            forwardCall();
        });

    function forwardCall() {
        // generate the TwiML to tell Twilio how to forward this call
        let twiml = new Twilio.twiml.VoiceResponse();
        let dialParams = {};
        twiml.dial(dialParams, recipientNumber);
        // return the TwiML
        callback(null, twiml);
    }

};
