这是我的平均代码。

const express = require('express');
const router = express.Router();
const passport = require('passport');
const jet = require('jsonwebtoken');

const Contact = require('../models/contacts');


// retrieving Data
router.get('/contacts',(req,res,next)=>{
 // res.send('Retriving the contact list');
 console.log('contacts page');
Contact.find(function(err, contacts){
 res.json(contacts);
})
});

// to add the content 
router.post('/contact',(req, res, next)=>{
// logic to add contact
    let newContact = new Contact({
        first_name: req.body.first_name,
        last_name: req.body.last_name,
        email_id: req.body.email_id,
        password: req.body.password
    });
    Contact.addRegistry((err, contacts)=> {
        if(err) {
            res.json({msg:'faild to add register'});
        }
        else{
            res.json({msg:'registry added sucessfully'});
        }

    });

});    
// to delete the content 
router.delete('/contact/:id',(req, res, next) =>{
    // logic to delete contact
    Contact.remove({_id:req.params.id}, function(err, result){
        if(err){
            res.json(err);
        }
        else {
            res.json(result);
        }
    });
    })    

module.exports = router;

上面的文件是route.js。 以下代码来自contact.js

// Database code.
var express = require('express');
var app = express();     
var mongoose = require('mongoose');     
var bcrypt = require('bcryptjs');             



// database schaema  
var ContactSchema = new mongoose.Schema({
    first_name: String,
    last_name: String,
    id: String,
    location: String,
    profile_picture_url: String,
    email_id: String,
    phone: String,
    job_title: String,
    company: String,
    education: String,
    password: String,
     savedjobslist: {
        title: [],
        subtitle: []

     },
    appliedjobslist: {
        title: [],
        subtitle: []
    },
    failedjobslist: {
        title: [],
        subtitle: []
    }
});


const Contact = module.exports = mongoose.model('Contact', ContactSchema); 

module.exports.getUserById = function(id,callback) {
    Contact.findById(id,callback);
}
module.exports.getUserById = function(username,callback) {
    const query = {username: username}
    Contact.findOne(query,callback);
}
module.exports.addRegistry = function(newContact,callback) {
    bcrypt.genSalt(10, (err,salt) => {
        bcrypt.hash(newContact,salt, (err,hash) => {
            if (err) {
                console.log(err);
            }
           newContact.password = hash;
           newContact.save(callback);
        });
    });
}

我正试图从邮递员那里发布数据,这就是错误

3 个答案:

答案 0 :(得分:1)

你有一个问题:

生成的

bcrypt因错误的参数而引发错误。您无法将对象(newContact)传递给bcrypt

尝试使用以下代码生成哈希:

const salt = bcrypt.genSaltSync(10);
const hashedPassword = bcrypt.hashSync(password, salt);

您可以在存储时使用pre save function of mangoose生成hashedPassword。就个人而言,我不喜欢,因为每次保存对象时都会添加新的检查

find()将查询作为参数搜索所有传递{}

Contact.find({},function(err, contacts){
res.json(contacts);
})

答案 2 :(得分:0)

  

Contact.addRegistry等待newContact作为第一个参数,但是你没有在你的route.js上传递它。

我想你想做这样的事情

ContactSchema.pre('save', function(next) {
  const user = this;

  // generate a salt
  bcrypt.genSalt(10, function(err, salt) {
    if (err) return next(err);

    // hash your password
    bcrypt.hash(user.password, salt, function(err, hash) {
      if (err) return next(err);

      // store hash on the password field
      user.password = hash;
      next();
    });
  });
});
