<?php/** * Created by PhpStorm. * User: Administrator * Date: 2016-7-21 * Time: 10:12 */if ($_SERVER["REQUEST_METHOD"] == "POST") {// echo json_encode(array("111"=>"112")); if (isset($_POST["url"]) && isset($_POST["username"]) && isset($_POST["password"])) { $result = postDemo($_POST["url"], array("username" => $_POST["username"], "password" => $_POST["password"])); echo $result; } else { echo json_encode(array("msg2" => "!!!!!!!!!!!!!!!!!!!!!error!!!!!2")); }} else { echo json_encode(array("msg" => "error!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"));}function postDemo($url, $data){ $query = http_build_query($data); $options = array( "http" => array( "header" => "Content-type: application/x-www-form-urlencoded/r/n" . "Content-length:" . strlen($query) . "/r/n" . "User-Agent:MyAgent/1.0/r/n", "method" => "POST", "content" => $query ) ); $content = stream_context_create($options); $result = file_get_contents($url, false, $content); return $result;}//echo postDemo("http://192.168.4.101:90/PHPStudy4/server.php",array("username"=>"admin","password"=>"admin"));其中"url":"http://192.168.4.101:90/PHPStudy4/server.php",這個url就是我們向遠端的訪問地址.
