javascript - 从 JS 函数调用 NodeJS 函数

Question

我正在做一个基于 firebase 的项目，我需要链接一个向客户端脚本发送电子邮件的服务器端函数。

这是我的服务器端index.js 文件

const functions = require('firebase-functions');
var nodemailer = require('nodemailer');

var transporter = nodemailer.createTransport({
  service: 'gmail',
  auth: {
    user: 'xxx@gmail.com',
    pass: 'password'
  }
});

var mailOptions = {
  from: 'xxx@gmail.com',
  to: 'xxx@gmail.com',
  subject: 'Sending Email using Node.js',
  text: 'That was easy!'
};

transporter.sendMail(mailOptions, function(error, info){
  if (error) {
    console.log(error);
  } else {
    console.log('Email sent: ' + info.response);
  }
});

我想知道如何让 html 中的按钮调用脚本中的函数来调用 Transporter.sendMail。我以前从未接触过 Node js，所以请原谅我缺乏知识。

如果这有助于 Firebase 将我的文件夹设置为按服务器端和客户端文件的功能和公共(public)分隔

First initialize your HTML page with jQuery and on submitting the form send an Ajax request to the server as follows

$(document).ready(function() {

    $("#formoid").submit(function(event) {
        event.preventDefault();
        $.ajax({
            url: 'http://xxxxxxx.com/contact', // url where to submit the request
            type : "POST", // type of action POST || GET
            dataType : 'json', // data type
            data : $("#formoid").serialize(), // post data || get data
            success : function(result) {
                $('#formoid')[0].reset();
            },
            error: function(xhr, resp, text) {
                console.log(xhr, resp, text);
            }
        })

    });
});

Create a route called contact in your NodeJS server and listen for the contact request with All parameters required for your need. In the following case am using an express server and body parser to parse the data from incoming request

app.post('/contact', (req, res) => {
    var transporter = nodemailer.createTransport({
        service: "Gmail",
        auth: {
            user: "xxxxx",
            pass: "xxxxx"
        }
    });

    var mailOptions = {
        from: req.body.email,
        to: 'xxxxx@xx.com',
        subject: 'Contact form',
        text: 'From: ' + req.body.name + '\n Email: ' + req.body.email + '\nMessage: ' + req.body.msg
    };
    transporter.sendMail(mailOptions, function (error, info) {
        if (error) {
            res.status(500).json({
                message: "Error",
                error: error
            })
        } else {
            res.status(200).json({
                message: "Its working",
                response: info.response
            })
        }
    });
});

In the above request am sending the name:as name, email: as email and message: as msg
