【问题描述】：

我正在尝试构建一个网络平台，您可以在其中注册和调整您的个人资料。但是，我在编辑部分苦苦挣扎。注册和登录都很好，但其余的会给出 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);

后跟路由：

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;

还有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 表单中获取数据：

<!-- 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>

对于我糟糕的代码质量，我深表歉意。这是由于花了很长时间的工作而造成的，但我根本无法弄清楚（即使有教程和堆栈溢出）出了什么问题。

结果是 500 内部服务器错误。

【参考方案1】：

您的 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。

【讨论】：

嗨 Alacritas，我已经尝试过了。我将 HTML 方法从“post”更改为“put”，将 router.post('/profile.html', profile.changeProfile) 更改为 router.put(XXX)。不幸的是，这没有奏效。我在一篇文章中读到 HTML 无法在表单中使用 put 方法。还是这样吗？
