引入依赖
var express = require(‘express‘
);
var url = require(‘url‘
);
var bodyParser = require(‘body-parser‘
);
var app =
express();
// 核心逻辑模块
var sql = require(‘./login.js‘
);
app.use(bodyParser.urlencoded({
extended: true
}));
// 设置响应头
app.all(‘*‘,
function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*"
);
res.header("Access-Control-Allow-Methods","PUT,POST,GET,DELETE,OPTIONS"
);
res.header(‘Access-Control-Allow-Headers‘,‘x-requested-with,content-type,Access-Control-Allow-Origin‘
);
res.header("X-Powered-By",‘ 3.2.1‘
)
res.header("Content-Type", "application/json;charset=utf-8"
);
next();
});
// 暴露接口
app.post(‘/user‘,
function(req, res){
var query = url.parse(req.url,
true).query;
switch(query.ctr){
case ‘add‘
:
sql.catchres({type:‘INSERT‘,data:req.body},
function(msg){
res.send(msg);
});
break;
case ‘update‘
:
sql.catchres({type:‘UPDATE‘,data:req.body},
function(msg){
res.send(msg);
});
break;
case ‘delete‘
:
sql.catchres({type:‘DELETE‘,data:req.body},
function(msg){
res.send(msg);
});
break;
case ‘login‘
:
sql.catchres({type:‘SELECT‘,data:req.body},
function(msg){
res.send(msg);
});
break;
default:
res.send(‘undefined contrl!‘
);
}
});
// 监听端口
app.listen(‘8080‘,
function(){
console.log(‘listen at 8080‘
)
})
三、运行
node app.js
我们的服务器就启动了，监听8080端口，我们向8080端口发起请求：
