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);
  $options = array(
    "http" => array(
      "header" => "Content-type: application/x-www-form-urlencodedrn" .
        "Content-length:" . strlen($query) . "rn" .
        "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编程小技巧。
