用到的应用： 1.webstorm 2.Navicat for MySQL 3.postman
一.使用express创建项目
1.
npm install express-generator -g
2.
express myapp
二.使用Navicat for MySQL将mysql表引入,开启数据库
三.项目中引入sequlize-auto
参考文档：https://github.com/sequelize/sequelize-auto
1.
npm install -g sequelize-auto
2.创建auto.js
var SequelizeAuto = require('sequelize-auto')
var auto = new SequelizeAuto(
'hhdj', 'root', 'root', {
host: 'localhost',
dialect: 'mysql',
directory: './models', // prevents the program from writing to disk
port: '3306',
additional: {
timestamps: false
//...
}
}
)
auto.run(function (err) {
if (err) throw err;
console.log(auto.tables); // table list
console.log(auto.foreignKeys); // foreign key list
});
运行auto.js 命令： node ./auto.js
此时会在根目录下创建models文件夹
3.在此文件夹下创建index.js
写一个模板处理数据库映射,建create.js
let fs = require('fs')
let files = fs.readdirSync('./models')
let models = []
// 解析名称做成驼峰命名法
files.forEach(item => {
if (item != 'index.js') {
let names = item.split('.')[0].split('_')
let name = ''
for (let i = 1; i < names.length; i++) {
name += names[i].substring(0,1).toUpperCase() + names[i].substring(1)
}
models.push({name: name, path: './' + item})
}
})
// 文件内容模板
const template = `
var Sequelize = require('sequelize');
// 创建数据库连接
var sequelize = new Sequelize('hhdj', 'root', 'root', {
host: 'localhost',
dialect: 'mysql',
pool: {
max: 5,
min: 0,
idle: 10000
}
})
// 数据库模型名称及lujing
const models =${JSON.stringify(models, null, 4)}
// 数据模型输出
models.forEach(item => {
module.exports[item.name] = require(item.path)(sequelize, Sequelize)
})
`
fs.writeFile("./models/index.js", template, function () {
console.log('创建成功')
}) 运行： node ./create.js,
此时可在index.js中看到：
var Sequelize = require('sequelize');
// 创建数据库连接
var sequelize = new Sequelize('hhdj', 'root', 'root', {
host: 'localhost',
dialect: 'mysql',
pool: {
max: 5,
min: 0,
idle: 10000
}
})
// 数据库模型名称及lujing
const models =[
{
"name": "ApplyInfo",
"path": "./tb_apply_info.js"
},
{
"name": "Branch",
"path": "./tb_branch.js"
},
{
"name": "Carousel",
"path": "./tb_carousel.js"
},
{
"name": "Comment",
"path": "./tb_comment.js"
},
{
"name": "CommentRelation",
"path": "./tb_comment_relation.js"
},
{
"name": "CommentUser",
"path": "./tb_comment_user.js"
},
{
"name": "Coordinate",
"path": "./tb_coordinate.js"
},
{
"name": "Forum",
"path": "./tb_forum.js"
},
{
"name": "ForumComment",
"path": "./tb_forum_comment.js"
},
{
"name": "Impress",
"path": "./tb_impress.js"
},
{
"name": "Integral",
"path": "./tb_integral.js"
},
{
"name": "IntegralRule",
"path": "./tb_integral_rule.js"
},
{
"name": "News",
"path": "./tb_news.js"
},
{
"name": "Notice",
"path": "./tb_notice.js"
},
{
"name": "PartyStyle",
"path": "./tb_party_style.js"
},
{
"name": "Payfee",
"path": "./tb_payfee.js"
},
{
"name": "Picture",
"path": "./tb_picture.js"
},
{
"name": "Report",
"path": "./tb_report.js"
},
{
"name": "StudyFile",
"path": "./tb_study_file.js"
},
{
"name": "User",
"path": "./tb_user.js"
},
{
"name": "Manager",
"path": "./user_manager.js"
}
]
// 数据模型输出
models.forEach(item => {
module.exports[item.name] = require(item.path)(sequelize, Sequelize)
})
到此数据库部分写完了。
四。在routes文件夹下创建api文件夹，index.js
1.封装一个登陆接口。
a，先写一个util.js处理接口格式与检查token
var jwt = require('jwt-simple')
var User = require('../models').User
module.exports = function () {
// 检查token
this.checkToken = (req, res, next) => {
var t = req.headers['access-token']
if (!t) {
res.send(this.setResult(300, 'no token'))
return
}
var token = jwt.decode(t, 'hhdjj')
User.find({where: {id: token.id}})
.then(r =>{
req.TOKEN_USER = r
next()
})
.catch(r => {
res.send(this.setResult(300, 'token验证失败'))
})
}
// 设置token
this.setToken = (obj) => {
return jwt.encode(obj, 'hhdjj')
}
// 接口统一返回格式
this.setResult = (code, message='success', data = null) => {
return {
code: code,
message: message,
data: data
}
}
}
b，在index.js写入
const express = require('express')
const router =express.Router()
var Util = require('./util')
var a =new Util()
var crypto = require('crypto') // 用于密码加密
var User = require('../models').User
router.post('/user/login',function(req, res, next) { var phone = req.body.phone
var password = req.body.password
if (!phone) {
res.send(a.setResult(301, '账号空'))
return
}
if (!password) {
res.send(a.setResult(301, '账号空'))
return
}
var md5 = crypto.createHash('md5') // md5加密
var upPassword = password + 'hhdj'
var params = {
where: {
password: md5.update(upPassword).digest('hex'),
phone: phone
}
}
User.findOne(params)
.then( su => {
res.send(a.setResult(200, 'success', a.setToken(su)))
}
)
.catch( ex => {
// res.send({code: 500, message: 'error'})
res.send(a.setResult(500, 'error'))
}
))
module.exports = router
c.此时运行项目并使用postman调试。
五，使用apidoc写接口文档
接口文档：http://apidocjs.com/#demo
先下载 ： npm install apidoc --save
在上面的index.js写入
/**
* @api {post} /user/login Request User information
* @apiName 登录
* @apiGroup User
*
* @apiParam {String} phone 手机号.
* @apiParam {String} password 密码
*
* @apiSuccess {String} code 200 of the User.
* @apiSuccess {String} message success of the User.
* @apiSuccess {String} data 数据 of the User
*
* @apiSuccessExample Success-Response:
* HTTP/1.1 200 OK
* {
* 'code': 200,
* 'message': 'success',
* 'data': su
* }
*
* @apiError UserNotFound The id of the User was not found.
*
* @apiErrorExample Error-Response:
* HTTP/1.1 404 Not Found
* {
* 'code': 500,
* 'message': 'error'
* }
*/
在文档根目录下创建apidoc.json，写入
{
"name": "name",
"version": "1.0.0",
"description": "apiDoc basic example",
"title": "title",
"url" : "localhost:3000"
} 运行
apidoc -i routes/api/ -o apidoc/
此时会生成一个apidoc的文件夹，下面有个index.html,打开，即可看到我们封号的接口文档。
