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 contents = querystring.stringify({

    username: 'admin',

    password: '123456'

});

var options = {

    hostname: 'localhost',

    port: 9000,

    path: '/modules/login/checkSign.php',

    method: 'POST',

    headers:{

        "Content-Length":contents.length,

        "Content-Type":"application/x-www-form-urlencoded"
　　}

};

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();
