本文实例为大家分享了ajax实现远程通信,供大家参考,具体内容如下
第一个文件:html
<!DOCTYPE html> <html lang=\"en\"> <head> <meta charset=\"UTF-8\"> <title>ajax解决跨域问题</title> <script src=\"jquery-3.0.0.min.js\" type=\"text/javascript\"></script> </head> <body> <script> $.ajax({ type:\"POST\", url:\"postDemo.php\", data:{ \"url\":\"http://192.168.4.101:90/PHPStudy4/server.php\", \"username\":\"admin\", \"password\":\"admin\", },success:function(data){ var result=eval(\"(\"+data+\")\"); console.log(result); } }) </script> </body> </html>
第二个文件:服务器端处理数据
<?php /** * Created by PhpStorm. * User: Administrator * Date: 2016-7-21 * Time: 10:12 */ if ($_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\",这个url就是我们向远端的访问地址.
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持phpstudy。
