Question

我是Node的新手，我一直在尝试创建一个API并在邮递员中对其进行测试，但是从邮递员发送值后，我收到了此错误

     password:
      { ValidatorError: Path `password` is required.
          at new ValidatorError (D:\devconnector\node_modules\mongoose\lib\error\validator.js:29:11)
          at validate (D:\devconnector\node_modules\mongoose\lib\schematype.js:978:13)
          at D:\devconnector\node_modules\mongoose\lib\schematype.js:1031:11
          at Array.forEach (<anonymous>)
          at SchemaString.SchemaType.doValidate (D:\devconnector\node_modules\mongoose\lib\schematype.js:987:14)
          at D:\devconnector\node_modules\mongoose\lib\document.js:2101:9
          at processTicksAndRejections (internal/process/next_tick.js:74:9)
        message: 'Path `password` is required.',
        name: 'ValidatorError',
        properties: [Object],
        kind: 'required',
        path: 'password',
        value: undefined,
        reason: undefined,
        [Symbol(mongoose:validatorError)]: true } },
  _message: 'users validation failed',
  name: 'ValidationError' }

下面是我的server.js脚本

const express = require('express');
const mongoose = require('mongoose');
const users = require('./routes/api/users');
const profile = require('./routes/api/profile');
const posts = require('./routes/api/posts');
const bodyParser = require('body-parser');
const app = express();
//Body Parser middleware
app.use(bodyParser.urlencoded({extended: false}));
app.use(bodyParser.json());
//DB Config
const db = require('./config/keys').mongoURI;
//Connect to MongoDB
mongoose.connect(db).then(()=> console.log('MongoDB Connected')).catch(err => console.log(err));

app.get('/',(req,res)=>res.send('Hello World'));
//use routes
app.use('/api/users',users);
app.use('/api/profile',profile);
app.use('/api/posts',posts);
const port = process.env.PORT || 5000;
app.listen(port, ()=> console.log(`Server running on port ${port}`));

这是我的key.js脚本

module.exports={
    //mongoURI:'mongodb://root:qwerty123@devconnector-u2cub.mongodb.net:27017'
    mongoURI:'mongodb://127.0.0.1:27017/devconnector'
};

users.js脚本

const express = require('express');
const router = express.Router();
const gravatar = require('gravatar');
const bcrypt = require('bcryptjs');
// Load User model
const User = require('../../models/User');
//@route GET api/users/test
//@desc Tests post route
//@ access public
router.get('/test',(req, res) => res.json({msg: "Users Works2"}));
//@route GET api/users/register
//@desc Register user
//@ access public
router.post('/register',(req, res)=>{
    User.findOne({email:req.body.email})
    .then(user=>{
        if(user){
            return res.status(400).json({email: 'Email already exists'});
        }else{
            const avatar = gravatar.url(req.body.email,{
                s:'200',//size
                r: 'pg',//rating
                d: 'mm' //Default
            })
            const newUser = new User({
                name: req.body.name,
                email: req.body.email,
                avatar,
                password: req.body.password
            });
            bcrypt.genSalt(10, (err, salt)=>{
                bcrypt.hash(newUser.password, salt, (err, hash)=>{
                    //if(err)throw err;
                    newUser.password = hash;
                    newUser.save()
                    .then(user=> res.json(user))
                    .catch(err=> console.log(err));
                })
            })
        }
    })
});
module.exports = router;

最后我的用户模型

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
//Create Schema
const UserSchema = new Schema({
    name:{
        type: String,
        required: true,
    },
    email:{
        type: String,
        required: true
    },
    password:{
        type: String,
        required: true
    },
    avatar:{
        type: String,

    },
    date:{
        type: Date,
        default: Date.now
    },
});
module.exports = User = mongoose.model('users', UserSchema);

这也是邮递员的错误消息

Could not get any response
There was an error connecting to http://localhost:5000/api/users/register?name=RUGUMBIRA&email=rugumbirajordybastien@gmail.com&password=123456.
Why this might have happened:
The server couldn't send a response:
Ensure that the backend is working properly
Self-signed SSL certificates are being blocked:
Fix this by turning off 'SSL certificate verification' in Settings > General
Proxy configured incorrectly
Ensure that proxy is configured correctly in Settings > Proxy
Request timeout:
Change request timeout in Settings > General

请帮助，我在做什么错

Answer 1

从服务器上的错误消息中，您似乎正在使用Validator模块作为验证中间件，并且必须输入密码字段。但是，当您尝试在req.body对象中尝试访问注册详细信息时，它似乎也会作为查询传递。如果是这种情况，Validator会将req.body视为空，然后抛出错误。

与其在查询中传递名称，电子邮件和密码，不如将它们写入Postman请求的正文中。单击Postman应用程序上的“正文”选项卡，然后输入注册详细信息。
