# express 开发blog接口



## 1.安装脚手架（express-generator） 一键搭建 初始化express 

 ` cnpm install express-generator -g` 

` express express-test`

### 开发环境和生产环境的写法不同

` cnpm i nodemon croess-env -s`

package.json >

```javascript
"scripts": {
    "dev": "cross-env NODE_ENV=dev nodemon app.js",
    "prd": "cross-env NODE_ENV=production nodemon app.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
```

判断是否开发环境

```
if (process.env.NODE_ENV === "dev"){}
```

### post数据

```js
router.post('/login', function(req, res, next) {
	// 获取传入的post数据
	const {username,password} = req.body;
  res.json({
		errno:0,
		data:{
			username,
			password
		}
	});
});
```

## 2.mysql xxs框架安装

` cnpm install mysql xxs --save ` 

### 3.安装express-session   实现登录功能  一并安装redis 和 connect-redis

 `cnpm install express-session --save`  

`cnpm i redis connect-redis --save`

` const session = require('express-session')`

` const redisConnect = require('redis-connect')(session);`    connect-redis 使用



```
const redisCli = require('./db/reids.js')  // 引入创建的reids客户端
const sessionStore = new redisConnect({
  client: redisCli     // 把创建的reids客户端带入
})
app.use(session({
	secret:"AS#$_189", //类似密钥
	cookie:{
		paht: '/',
		httpOnly: true,
		maxAge: 24 *60 *60 *1000 //时间限制
	},
	store: sessionStore			// 设置reids
}))
```



## 日志 morgan

```js
const env = process.env.NODE_ENV;
if(env == 'dev'){
	app.use(logger('dev')); // 线上环境用 combined
}else{
    // 线上环境用 combined
	app.use(logger('combined')); 
}
```
