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.
