nodejs实现的简单接口

var http = require('http');
var mysql      = require('mysql');
var connection = mysql.createConnection({
host     : 'rm-bp1w72suk8pc5h6mk.mysql.rds.aliyuncs.com',
user     : 'r85u40z94p',
password : 'Mafeng11',
database: 'r85u40z94p'
});
//开始你的mysql连接
connection.connect();

var server = http.createServer(function (req, res) {
//如果你发一个GET到http://127.0.0.1:9000/test
var url_info = require('url').parse(req.url, true);
//检查是不是给/test的request
if(url_info.pathname === '/test'){
res.writeHead(200, {'Content-Type': 'text/plain'});

connection.query('SELECT * FROM `r85u40z94p`.`user`  order by rand()  LIMIT 5',function(err,rows,fields){
//处理你的结果
// res.end(rows.constructor);
// 输出结果
res.end(JSON.stringify(rows));

console.log(rows.constructor);
console.log(typeof(rows));
res.end(rows.join);
console.log(err);
console.log(fields);
});
}
//这个是用来回复上面那个post的，显示post的数据以表示成功了。你要是有别的目标，自然不需要这一段。
else{
req.pipe(res);
}
});
server.listen(9000, '127.0.0.1');
//在server关闭的时候也关闭mysql连接
server.on('close',function(){
connection.end();
});
console.log('listening on port  9000');
