NodeJS 使用内容以及模拟一个接口【二】

1.在routes下面新建一个目录为mysql--mysql.js

var mysql = require('mysql');
var dbMsg = {
    host     : 'localhost',
    user     : 'root',
    password : 'root',
    database : '数据库名称'
}
 
 
var connection = mysql.createConnection(dbMsg);
    connection.connect();
module.exports = connection;

2. 配置路由

 

var loginRouter = require('./routes/login');


app.use('/login', loginRouter);

3.在routes文件夹下面创建一个login.js

var express = require('express');
var URL = require('url');
var router = express.Router();
var connection = require('./mysql/mysql');



router.post('/user',function(req, res, next){
	var params = {
		username : req.query.username,
		password : req.query.password
	}
	var userStr = 'select * from user_info_t where login_name=? and password=?';
	var str = [params.username,params.password];
	console.log(userStr)
	connection.query(userStr,str,function(err,result){
        if(err){
            throw err;
        }else{
            res.send(result)
        }
    })
});



router.get('/', function(req, res, next) {

  var user = {
  	name:'',
  	age:'',
  	city:''
  };
  var params = URL.parse(req.url, true).query;

  if(params.id == '1') {
    user.name = "Mr.light";
    user.age = "1";
    user.city = "深圳市";
  } else {
    user.name = "Ms.lee";
    user.age = "2";
    user.city = "广东市";
  }
  var response = {status:1,data:user};
  res.send(JSON.stringify(response))
});




module.exports = router;

4.启动bin下面的www文件 node www

5.浏览器输入http://127.0.0.1:3000/login

 注意：记得安装 npm install mysql 模块

至此一个接口就这样完成了，如果有疑问记得留言 源码地址：https://gitee.com/qwerdfs/NodeJS/tree/master/nodePriject
