ajax实现远程通信

前端技术 2023/09/06 AJAX

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
/**

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.
