Question

我对node.js还是很陌生，我正在尝试使用nodemailer发送电子邮件，并且目前在控制台上遇到类型错误。

//错误// [0] TypeError：express.createServer不是函数 app.post上的[0]（/Users/thomashunt/Desktop/react_express_starter/server.js:33:17） [0]在Layer.handle [作为handle_request]（/Users/thomashunt/Desktop/react_express_starter/node_modules/express/lib/router/layer.js:95:5）下一个[0]（/Users/thomashunt/Desktop/react_express_starter/node_modules/express/lib/router/route.js:137:13） [0]在Route.dispatch（/Users/thomashunt/Desktop/react_express_starter/node_modules/express/lib/router/route.js:112:3） [0]在Layer.handle [作为handle_request]（/Users/thomashunt/Desktop/react_express_starter/node_modules/express/lib/router/layer.js:95:5） [0]位于/Users/thomashunt/Desktop/react_express_starter/node_modules/express/lib/router/index.js:281:22 [0]在Function.process_params（/Users/thomashunt/Desktop/react_express_starter/node_modules/express/lib/router/index.js:335:12）下一个[0]（/Users/thomashunt/Desktop/react_express_starter/node_modules/express/lib/router/index.js:275:10） [0]在urlencodedParser（/Users/thomashunt/Desktop/react_express_starter/node_modules/body-parser/lib/types/urlencoded.js:82:7） [0]在Layer.handle [作为handle_request]（/Users/thomashunt/Desktop/react_express_starter/node_modules/express/lib/router/layer.js:95:5）

//错误结束

这是我server.js文件的代码：

const nodemailer = require('nodemailer')
const path = require('path')
const express = require('express')
const app = express()
const port = 5000
const cors = require('cors')
app.use(cors())
const bodyParser = require('body-parser')
app.use(bodyParser.json())
// to support JSON-encoded bodies
app.use(
  bodyParser.urlencoded({
    // to support URL-encoded bodies
    extended: true
  })
)

app.get('/home', (req, res) => {
  console.log(
    'Hello from .get /home',
    req.body.generalDetails,
    req.body.firstName,
    req.body.mName
  )
})

app.post('/home', (req, res) => {


  var express = require('express'),
  nodemailer = require("nodemailer");

  app = express.createServer();

  app.use(express.bodyParser());

  app.post('/formProcess', function (req, res) {
      var data=req.body;

      var smtpTransport = nodemailer.createTransport("SMTP",{
         service: "Gmail",
         auth: {
         user: "thomas.hunt@careertrackers.org.au",
         pass: "pass"
         }});

     smtpTransport.sendMail({  //email options
     from: "email",
     to: "thomas.hunt@careertrackers.org.au", // receiver
     subject: "Emailing with nodemailer", // subject
     text:req.body.generalDetails,
     html: "here your data goes"// body (var data which we've declared)
      }, function(error, response){  //callback
           if(error){
             console.log(error);
          }else{
             console.log("Message sent: " + res.message);
         }

     smtpTransport.close();
      }); });

  let data = [{
    //page one data
    generalDetails: req.body.generalDetails,
    fName: req.body.fName,
    mName: req.body.mName,
    lName: req.body.lName,
    email: req.body.email,
   }];

   res.json(data);

 }

);

app.listen(port, () => `Server running on port ${port}`);

Answer 1

我认为您对Discount d1 = new Discount("CODE_1"); Discount d2 = new Discount("CODE_2"); List<Discount> discounts = List.of(d1, d2); discounts.forEach(discount -> discount.setDesc(TypeCode.valueOf(discount.getTypeCode()).getDesc()));模块感到困惑。替换您的

http

与

app = express.createServer();

如果您想使用app = express();，则应执行以下操作

createServer

nodejs / express express.createserver不是函数
