学习实践之DEMO《nodejs模拟POST登陆》

一个简单的PHP接收参数页面

<?php
    header("content-type:text/html;charset=utf-8");
    if($_POST[username] == "admin" && $_POST[password] == "123456") {
        echo "登陆成功";
    }else {
        echo "登陆失败";
    }
?>

nodejs代码实现模拟登陆示例

var http = require("http");
var querystring = require("querystring"); 

var options = {
    hostname: ‘localhost‘,
    port: 9000,
    path: ‘/modules/login/checkSign.php‘,
    method: ‘POST‘,
    headers:{
        //
        "Accept":"text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
        "Accept-Encoding":"gzip,deflate",
        "Accept-Language":"zh-CN,zh;q=0.8,en;q=0.6",
        "Cache-Control":"max-age=0",
        "Connection":"keep-alive",
        "Content-Length":"30",
        "Content-Type":"application/x-www-form-urlencoded",
        "Cookie":"",
        "Host":"localhost:9000",
        "Origin":"http://localhost:9000",
        "Referer":"http://localhost:9000/modules/login/",
        "User-Agent":"Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.111 Safari/537.36"
        //
    }
};
var contents = querystring.stringify({
    username: ‘admins‘,
    password: ‘123456‘
});
var req = http.request(options, function(res) {
    res.setEncoding(‘utf8‘);
    res.on(‘data‘, function (data) {
        console.log(‘BODY:‘ + data);
    });
});

req.on(‘error‘, function(e) {
    console.log(‘problem with request: ‘ + e.message);
});

req.write(contents);
req.end();
