修改 Twilio 示例代码以附加语音邮件重新编码并通过电子邮件发送

Question

来自 Twilio 的以下 post 解释了如何编写和实现用于将录制消息的 link 发送到电子邮件的功能。

我想附加到语音信箱录音而不只是发送 link。这是我修改他们的代码的尝试。不幸的是，它导致了 500 错误。我对 NodeJS 不是很了解，所以也许你可以提供帮助。

包括 SendGrid 和 FS 的依赖项，并且在我用 FS、pathToAttachment、附件变量和附件数组修改它之前，此函数运行完美。

//Initialize SendGrid Mail Client
const sgMail = require('@sendgrid/mail');

//FileSystem
const fs = require("fs");

// Define Handler function required for all Twilio Functions
exports.handler = function(context, event, callback) {
    
pathToAttachment = `${event.RecordingUrl}`;
attachment = fs.readFileSync(pathToAttachment).toString("base64");

// Build SG mail request
sgMail.setApiKey(context.SENDGRID_API_SECRET);
        // Define message params
        const msg = {
          to: context.TO_EMAIL_ADDRESS,
          from: context.FROM_EMAIL_ADDRESS,
          fromname: 'Voicemail',
          text: `URL is: ${event.RecordingUrl}`,
          subject: `${event.From} (${event.country} / ${event.lang})`,
          attachments: [
            {
                content: attachment,
                filename: "Voicemail.wav",
                disposition: "attachment"
            }
          ]
        };
        // Send message
        sgMail.send(msg)
        .then(response => {
            console.log("Neat.")
            callback();
        })
        .catch(err => {
            console.log("Not neat.")
            callback(err);
        });
};

这是您修改 Twilio 博客中的代码的方式：

使用 Studio、Functions 和 SendGrid 将语音邮件录音转发到电子邮件 https://www.twilio.com/blog/forward-voicemail-recordings-to-email

.. 附加电子邮件记录而不是 link 以及如何添加 from name作为发件人电子邮件地址。

const request = require('request');
const sgMail = require('@sendgrid/mail');

exports.handler = function(context, event, callback) {
  
    const fileUrl = event.RecordingUrl;
  
    // Build SG mail request
    sgMail.setApiKey(context.SENDGRID_API_SECRET);

    request.get({ uri: fileUrl, encoding: null }, (error, response, body) => {
    
        const msg = {
            to: context.TO_EMAIL_ADDRESS,
            from: {
                "email": context.FROM_EMAIL_ADDRESS,
                "name": `My company`
            },
            text: `Attached voicemail from ${event.From}.`,
            subject: `${event.From}`,
            attachments: [
                {
                    content: body.toString('base64'),
                    filename: `MyRecording.wav`,
                    type: response.headers['content-type']
                }
            ]
        };
        // Send message
        sgMail.send(msg)
        .then(response => {
            console.log("Neat.")
            callback();
        })
        .catch(err => {
            console.log("Not neat.")
            callback(err);
        });
    });
};
