# 随堂练习：完成登录、注册功能
## 学习mongodb
* [http://nodeonly.com/nodesang/#/4](http://nodeonly.com/nodesang/#/4)
* [https://github.com/DanialK/Simple-Authentication](https://github.com/DanialK/Simple-Authentication)
## 添加mongoose
~~~
mkdir models
npm i -S mongoose
npm i -S mongoosedao
~~~
在路由里增加创建代码
### 配置
配置mongodb链接信息
* config/mongodb.example.js
* db.js
~~~
cp config/mongodb.example.js config/mongodb.js
~~~
### 创建models/user.js
~~~
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var MongooseDao = require('mongoosedao');
var userSchema = new Schema(
{
"name":"String",
"password":"String"
}
);
var User = mongoose.model('User', userSchema);
var UserDao = new MongooseDao(User);
module.exports = UserDao;
~~~
### 测试user.js
~~~
var request = require('supertest');
var assert = require('chai').assert;
var expect = require('chai').expect;
require('chai').should();
require('../db')
var User = require('../models/user')
// 测试代码基本结构
describe('UserModel', function(){
before(function() {
// runs before all tests in this block
})
after(function(){
// runs after all tests in this block
})
beforeEach(function(){
// runs before each test in this block
})
afterEach(function(){
// runs after each test in this block
})
describe('#save()', function(){
it('should return stuq when user save', function(done){
User.create({"name":"stuq","password":"password"},function(err, user){
if(err){
expect(err).to.be.not.null;
done();
}
expect(user.name).to.be.a('string');
expect(user.name).to.equal('stuq');
done();
});
})
})
})
~~~
在测试完成后需要在after里删除测试数据，保证测试完整性，自己写吧
### 在路由里增加user创建和api测试
routes/user.js
~~~
var User = require('../models/user')
router.post('/register', function(req, res, next) {
var name = req.body.name;
var password = req.body.password;
User.create({
"name":name,
"password":password
},function(err, user){
if(err){
res.json('register failed with err');
}
res.json('register sucess');
});
});
~~~
test/user_api.js
~~~
var request = require('supertest');
var assert = require('chai').assert;
var expect = require('chai').expect;
require('chai').should();
var app = require('../app');
require('../db')
describe('POST /users/register', function(){
it('respond register with json', function(done){
request(app)
.post('/users/register')
.field('name', 'stuq')
.field('password', '123456')
.set('Accept', 'application/json')
.expect('Content-Type', /json/)
.expect(200, done);
})
})
~~~
测试
~~~
mocha -u bdd test/user_api.js
~~~
## 登录
routes/user.js
~~~
var User = require('../models/user')
router.post('/login', function(req, res, next) {
var name = req.body.name;
var password = req.body.password;
User.findOne({
"name":name,
"password":password
},function(err, user){
if(err){
res.json('register failed with err');
}
res.json('register sucess');
});
});
~~~
这是示意，实际代码的密码地方是不会这样写的。采用加盐加密方式
