通过Express / Node JS从HTML编辑configuration文件到MongoDB

我试图build立一个networking平台，在那里你可以注册和适应你的个人资料。 不过，我正在努力编辑部分。 注册和login是好的，但其余的给HTTP 500.所以，这就是我所做的： 

User Scheme for Mongoose: var mongoose = require('mongoose'); var Schema = mongoose.Schema; var passportLocalMongoose = require('passport-local-mongoose'); //enhanced userSchema var UserSchema = new Schema({ user_id: Schema.ObjectId, username: {type :String, required : true, unique : true}, //serves as unique identifier password: {type : String, required: true}, name: {type : String, required : true}, surname: String, created_at : Date, updated_at : Date, skills: [{type : String}], lectures: [{type : String}], groups: [{type : String}] //todo: Change for later cross referencing with group schemes }); UserSchema.plugin(passportLocalMongoose); module.exports = mongoose.model('User', UserSchema);

其次是路由： 

 var express = require('express'); var router = express.Router(); var auth = require("../controllers/AuthController.js"); var profile = require ("../controllers/ProfileController"); // restrict index for logged in user only router.get('/', auth.home); // route to register page router.get('/register.html', auth.register); // route for register action router.post('/register.html', auth.doRegister); // route to login page router.get('/login.html', auth.login); // route for login action router.post('/login.html', auth.doLogin); // route for logout action router.get('/logout.html', auth.logout); //route to profile router.get('/profile.html', profile.goToProfile); //route for changing profile router.post('/profile.html', profile.changeProfile); module.exports = router;

和profileController 

 /** * Controller for editing the profile */ var mongoose = require("mongoose"); var passport = require("passport"); var User = require("../models/User"); var path = require('path'); //Change Name var profileController = {}; //go to Profile profileController.goToProfile = function (req, res){ res.sendFile(path.resolve('login.html')), {user : req.user}; } profileController.changeProfile= function (req, res){ console.log("REQUEST: " + req.body.toString()); if (req.body.surname.isEmpty()){ } else { User.findByIdAndUpdate(req.user._id, { $set: { surname: req.body.surname }}, { new: true }, function (err, User) { if (err) { console.log(err.toString());} res.alert('Changed surname'); console.log('changed surname') }); }; if (req.body.name.isEmpty()){} else { User.findByIdAndUpdate(req.user._id, { $set: { name: req.body.name }}, { new: true }, function (err, User) { if (err) { console.log(err.toString());} res.alert('Changed name'); console.log('changed name') }); }; if (req.body.skills.length === 0){} else { User.findByIdAndUpdate(req.user._id, { $set: { skills: req.body.skills }}, { new: true }, function (err, User) { console.log("Old Skills: " + User.skills.toString()); if (err) { console.log(err.toString());} console.log("New skills: " + User.skills.toString()); console.log('changed skills') }); } }; module.exports = profileController;

从这个HTML表单获取数据： 

 <!-- register container --> <div class="container"> <form role="form" action="profile.html" method="post" style="max-width: 300px;"> <h2 class="form-heading">Your Profile</h2> <input type="text" name="name" placeholder="Name" class="form-control" /> <input type="text" name="username" placeholder="Username" class="form-control" /> <input type="text" name="surname" placeholder="Last Name" class="form-control"/> <input type="text" name="skills[]" placeholder="Your skills" class="form-control"/> <button type="submit" class="btn btn-lg btn-primary btn-block">Save</button> </form> </div>

我很抱歉我的代码质量不好。 这是在这个工作了很长时间的结果，但我根本无法弄清楚（甚至在教程和堆栈溢出）出了什么问题。

结果是500内部服务器错误。

谢谢你的帮助，同行的编码！

你的PUT请求在哪里？ 要更新数据，您需要使用PUT请求。 POST用于添加新条目。

这个快速应用程序在哪里托pipe？ 你可以访问服务器日志，并检查可能导致从该日志信息500错误？
