我在正在处理的应用程序上使用带有 Node 的express.js 时遇到路由错误。我无法正确处理 post 请求，并收到 http 500 错误，这是我的 server.js 文件代码

var express = require('express');
var app = express();
app.set('view engine', 'ejs');
var expressValidator = require('express-validator');
app.use(expressValidator());
var router = express.Router();
app.use(router);


var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({extended: true}));
app.use(bodyParser.json());

var methodOverride = require('method-override');
app.use(methodOverride(function (req, res) {
    if (req.body && typeof req.body === 'object' && '_method' in req.body) {
        var method = req.body._method;
        delete req.body._method;
        return method
    }
}));

var flash = require('express-flash');
var cookieParser = require('cookie-parser');
var session = require('express-session');
app.use(cookieParser('csci3308'));
app.use(session({
    secret: 'csci3308',
    resave: false,
    saveUninitialized: true,
    cookie: {maxAge: 60000}
}));
app.use(flash());



var login = require('./routes/login');
var success =  require('./routes/success');
var profileCreation = require('./routes/profileCreation');
var calendar = require('./routes/calendar');
var student = require('./routes/student');
var professor = require('./routes/professor');

app.use(express.static('public'));
app.use('/', login);
app.use('/login', login);
app.use('/success', success);
app.use('/profileCreation', profileCreation);
app.use('/calendar', calendar);
app.use('/student', student);
app.use('/professor', professor);




//error handling
app.use((req, res, next) => {
  console.log(req.url)
  console.log(req.method)
  console.log(req.params)
  console.log(req.body)
  res.status(404).send("Sorry can't find that!")
})

app.use((err, req, res, next) =>{
  console.error(err.stack)
  res.status(500).send('Something broke!')
})


var port = 4000;
app.listen(port, function () {
    console.log('Server running on http://localhost:' + port)
});

这是我的 profileCreation.js 代码 

var express = require('express');
var router = express.Router();
var expressValidator = require('express-validator');
router.use(expressValidator());
const { check } = require('express-validator/check');
var db = require('../database.js');



router.post('/profileCreation', function(request, response){
  console.log("made it to profileCreation post route")
  response.redirect('/login')
  //request.assert('email', 'email is required').notEmpty();
  // request.assert('pswd', 'password is required').notEmpty();
  // request.assert('cfmPswd', 'confirm password is required').notEmpty();
  // request.assert('pswd', 'password and confirm password are not the same').equals('cfmPswd');
  // var queryCheckEmailNotTaken = 'select (email) from users where(email = $1)';
  // if(db.oneOrNone(queryCheckEmailNotTaken, 'email')=== null){
  //   //make eroor message
  //   request.flash('error', 'Creation failed');
  //   response.render('profileCreation');
  // }
  // else{
  //   var isProf = document.getElementById("isProfessor").checked;
  //   //var dbQueryAddUserString = 'Insert into users(email, pswd, isProffessor) values(request.sanitize('email'), request.sanitize('pswd'), isProf;
  //   var dbQueryAddUserString = 'Insert into users(email, pswdID, isProffessor) values($1, $2, $3)';
  //   db.none(dbQueryAddUserString, [email,pswd, isProf]).then(
  //       response.render('login')
  //       ).catch(function(error){
  //           request.flash('error', 'Creation failed');
  //           response.render('profileCreation');
  //       })
  //   }
});




router.get('/', function (request, response) {
   console.log('Made it to profile creation root route');
   response.render('profileCreation', {data: {}});
});

router.get('/profileCreation', function(request, response){
    console.log('Made it to profileCreation route');
    response.render('profileCreation');
});


module.exports = router;

这是我的 profileCreation.ejs 代码

当我尝试在配置文件创建路径上使用提交按钮时，收到 500 错误。我不知道是什么问题。这就像路由器没有正确定义处理 post 请求的路由。我使用与登录功能相同的公式，但由于某种原因它不起作用。本地服务器表示无法发布到路由。请帮我。我很感激任何反馈。我是这方面的业余爱好者，认为这可能只是某个地方的一个小错误。先感谢您!

最佳答案

您可以尝试使用访问

BASE_URL + 'profileCreation/profileCreation'

注意:将 BASE_URL 替换为您的实际基本 URL
