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
" ."Content-length:" . strlen($query) . "
" ."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.
