ajax实现远程通信
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
<!DOCTYPEhtml>
<htmllang="en">
<head>
<metacharset="UTF-8">
<title>ajax解决跨域问题</title>
<scriptsrc="jquery-3.0.0.min.js"type="text/javascript"></script>
</head>
<body>
<script>
$.ajax({
type:"POST",
url:"postDemo.php",
data:{
"url":"http://192.168.4.101:90/PHPStudy4/server.php",
"username":"admin",
"password":"admin",
},success:function(data){
varresult=eval("("+data+")");
console.log(result);
}
})
</script>
</body>
</html>
第二个文件：服务器端处理数据
<?php
/**
*CreatedbyPhpStorm.
*User:Administrator
*Date:2016-7-21
*Time:10:12
*/
if($_SERVER["REQUEST_METHOD"]=="POST"){
//echojson_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$result;
}else{
echojson_encode(array("msg2"=>"!!!!!!!!!!!!!!!!!!!!!error!!!!!2"));
}
}else{
echojson_encode(array("msg"=>"error!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"));
}
functionpostDemo($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;
}
//echopostDemo("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.
