MEAN -“post”在邮差测试时给出错误消息，无法预测问题

Question

我正在使用MEAN应用程序，我已经与name,username,password创建了一个post request -我正在尝试使用postman chrome插件进行测试。

但我总是得到一个错误，而不是我的数据张贴。我是这样连接db的:

mongoose.connect( 'mongodb://jbarif:[e-mail]:47975/family', function( err ) {
    if( err ) console.log( err );
    console.log( 'connection successful!' ); //getting consoled
} );

像这样发布数据:

"use strict";
var User = require('../models/userModel');
module.exports = function( express, app ){
    var openApi = express.Router();
    openApi.post('/create', function( req, res ){
        var user = new User();
        var name = req.body.name;
        var username = req.body.username;
        var password = req.body.password;
        console.log( name, username, password  + 'n' + user );

        user.save(function(err) {
            if (err) {
                // duplicate entry
                if (err.code == 11000)
                    return res.json({ success: false, message: 'A user with that username already exists. '});
                else
                    return res.send(err); //always getting this!
            }
            res.json({ message: 'User created!' });
        });
    });
    //prefixing the open apis
    app.use('/open', openApi);
    return openApi;
}

下面是postman的错误:

{
    "message": "User validation failed",
    "name": "ValidationError",
    "errors": {
        "password": {
            "message": "Path `password` is required.",
            "name": "ValidatorError",
            "properties": {
                "type": "required",
                "message": "Path `{PATH}` is required.",
                "path": "password"
            },
            "kind": "required",
            "path": "password"
        },
        "username": {
            "message": "Path `username` is required.",
            "name": "ValidatorError",
            "properties": {
                "type": "required",
                "message": "Path `{PATH}` is required.",
                "path": "username"
            },
            "kind": "required",
            "path": "username"
        }
    }
}

我的server.js:

var 
    express     = require('express'),
    path        = require('path'),
    morgan      = require('morgan'),
    bodyParser  = require('body-parser'),
    port        = process.env.PORT || 8080,
    mongoose    = require('mongoose'),
    openApi     = require('./app/api/openApi'),
    familyApi   = require('./app/api/familyApi'),
    app         = express();
    //app config;-
var base        = app.use( express.static( __dirname + '/public') );
var reqest      = app.use( morgan('dev') );
var jsonParse   = app.use( bodyParser.json() );
var urlParse    = app.use( bodyParser.urlencoded({extended:true}));

mongoose.connect( 'mongodb://jbarif:[e-mail]:47975/family', function( err ) {
    if( err ) console.log( err );
    console.log( 'connection successful!' );
} );
// mongoose.connect('mongodb://node:[e-mail]:13456/practical');
    //calling api from another files;
    openApi( express, app );
    familyApi( express, app );

    app.get('/', function( req, res ) {
        res.sendFile( path.join( __dirname + '/public/app/views/index.html') );
    });
    app.get('*', function( req, res, next ) {
        return res.status(404).json({success: false, message: 'Route '' + req.url + '' is invalid.'});
    });
    app.listen( port );
    console.log('app is listening at', port );

Answer 1

Mongoose验证失败，因为用户对象中没有任何内容。

改为:

var userData = {name: req.body.name, username: req.body.username,  password:req.body.password};
var user = new User(userData);
