node.js - 如何使用 react.js 前端发送电子邮件？

问题描述

我已经创建了一个网站并在我的网站上部署了它（使用 react js），有一个联系表格，可以将客户消息发送到我的工作电子邮件（myname@comany.com）。我知道我不能用 react js 发送电子邮件，因为 rereact 只处理前端，所以我正在寻找使用 nodemailer 或其他解决方案的解决方案！我怎样才能做到这一点？

我尝试使用以下教程将 react 与 express 联系起来：[https://medium.com/@maison.moa/setting-up-an-express-backend-server-for-create-react-app-bc7620b20a61][1]

我制作了一个快速应用程序进行测试：文件夹结构：

client ( created with create-react app )
node_modules
config.js
package.json
package_lock.json
server.js

在前端：client/src app.js 代码：

import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
import Form from './Form.js';

class App extends Component {
state = {
    data: null
  };

  componentDidMount() {
      // Call our fetch function below once the component mounts
    this.callBackendAPI()
      .then(res => this.setState({ data: res.express }))
      .catch(err => console.log(err));
  }
    // Fetches our GET route from the Express server. (Note the route we are fetching matches the GET route from server.js
  callBackendAPI = async () => {
    const response = await fetch('/express_backend');
    const body = await response.json();

    if (response.status !== 200) {
      throw Error(body.message) 
    }
    return body;
  };

  render() {
    return (
      <div className="App">
        <header className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h1 className="App-title">Welcome to React</h1>
        </header>
      <Form/>
        <p className="App-intro">{this.state.data}</p>
      </div>
    );
  }
}

export default App;

电子邮件.js 代码：

import React from 'react';
import { Email, Item, A} from 'react-html-email';
export default function InlineLink({name, children}) {
  return (
  <Email title='link'>
    <Item>
       Hello {name}
       <p>helooo</p>
    </Item>
    <Item>
      {children}
    </Item>
  </Email>
)};

Form.js 代码：

import MyEmail from './Email'
import { renderEmail } from 'react-html-email'
import axios from 'axios';
import React, { Component } from 'react';

class Form extends Component {

    resetForm(){

        this.setState({feedback: ''});
    }

    constructor(props) {
        super(props);
        this.state = { feedback: '', name: 'Name', email: 'email@example.com' };
        this.handleChange = this.handleChange.bind(this);
        this.handleSubmit = this.handleSubmit.bind(this);
      }

   
  render() {
    return (
        <form className="test-mailing">
        <h1>Let's see if it works</h1>
        <div>
        <textarea
            id="test-mailing"
            name="test-mailing"
            onChange={this.handleChange}
            placeholder="Post some lorem ipsum here"
            required
            value={this.state.feedback}
            style={{width: '100%', height: '150px'}}
        />
        </div>
        <input type="button" value="Submit" className="btn btn--submit" onClick={this.handleSubmit} />
    </form>
    );
  }
  handleChange(event) {
    this.setState({feedback: event.target.value})
  };
  handleSubmit(event){

    const messageHtml =  renderEmail(
      <MyEmail name={this.state.name}> {this.state.feedback}</MyEmail>
    );
    
            axios({
                method: "POST", 
                url:"http://localhost:3000/send", 
                data: {
              name: this.state.name,
              email: this.state.email,
              messageHtml: messageHtml
                }
            }).then((response)=>{
                if (response.data.msg === 'success'){
                    alert("Email sent, awesome!"); 
                    this.resetForm()
                }else if(response.data.msg === 'fail'){
                    alert("Oops, something went wrong. Try again")
                }
            })
        }
}
export default Form;

在后端 server.js 代码中：

const express = require('express');
const app = express();
const port = process.env.PORT || 5000;

// console.log that your server is up and running
app.listen(port, () => console.log(`Listening on port ${port}`));

// create a GET route
app.get('/express_backend', (req, res) => {
  res.send({ express: 'YOUR EXPRESS BACKEND IS CONNECTED TO REACT' });
});
const nodemailer = require('nodemailer');
const creds = require('./config');

var transport = {
  host: 'smtp.gmail.com', // e.g. smtp.gmail.com
  auth: {
    user: creds.USER,
    pass: creds.PASS
  }
}

var transporter = nodemailer.createTransport(transport)

transporter.verify((error, success) => {
  if (error) {
    console.log(error);
  } else {
    console.log('All works fine, congratz!');
  }
});
app.use(express.json()); app.post('/send', (req, res, next) => {
    const name = req.body.name
    const email = req.body.email
    const message = req.body.messageHtml
  
  
    var mail = {
      from: name,
      to: 'mellitir11@gmail.com',  
      subject: 'Contact form request',
  
      html: message
    }
  
    transporter.sendMail(mail, (err, data) => {
      if (err) {
        res.json({
          msg: 'fail'
        })
      } else {
        res.json({
          msg: 'success'
        })
      }
    })
  })

config.js 代码：

module.exports = {
    USER: 'mellitir11@gmail.com', 
    PASS: 'my_email_password',
}

即使它显示错误消息“糟糕，出了点问题。再试一次”[1]：https ://medium.com/@maison.moa/setting-up-an-express-backend-server-for-创建反应应用程序 bc7620b20a61
