1.前端页面

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="ko" lang="ko">

<head>

<title>Cross-Browser QRCode generator for Javascript</title>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

<meta name="viewport" content="width=device-width,initial-scale=1,user-scalable=no" />

<script type="text/javascript" src="jquery.min.js"></script>

<script type="text/javascript" src="qrcode.js"></script>

</head>

<body>

<button class="suning">点击</button>

<script type="text/javascript">

$(".suning").click(function(){

$.ajax({

url: 'headers.php',

data: {'key':'123'},//如果需要字符串json方式，请使用JSON.stringify(setting.data)

type: 'POST',

//dataType: 'json',

//contentType: 'application/json',

//processData: true,//为true不会序列化数据

beforeSend: function () {

// layer.load(2);

},

headers: {

"token":'token7758521'//自定义token及值

},

success: function (responseData) {

console.log(responseData);

},

error: function (error) {

console.log(error);

}

});

});

</script>

</body>

2.php页面

<?php

$arr = get_getallheaders();//获取http头数组

//echo $arr["Token"];//输出Token

var_dump($arr);//输出整个数组

function get_getallheaders() //定义方法

{

foreach ($_SERVER as $name => $value) //循环_SERVER数组

{

if (substr($name, 0, 5) == 'HTTP_') //前5个字符是HTTP_的进入循环

{

$headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))))] = $value;

//注释

//substr($name, 5)，从$name第5个字符向后截取

//str_replace('_', ' ',)下划线替换成空格

//strtolower()全部转换为小写

//ucwords()首字母转换为大写

//str_replace(' ', '-',)所有空格替换为-

}

}

return $headers; //返回前key前5个字符是HTTP_的数组

//return $_SERVER; //返回_SERVER数组

}
