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 }

3.php页面返回的headers

array(11) {
 ["Cookie"]=>
 string(94) "Hm_lvt_f62fa14829605f0d29c05da9c30e045a=1503649309,1503884728; _ga=GA1.1.1091059248.1504832863"
 ["Accept-Language"]=>
 string(14) "zh-CN,zh;q=0.8"
 ["Accept-Encoding"]=>
 string(17) "gzip, deflate, br"
 ["Referer"]=>
 string(62) "http://localhost/DianNaoBengKuiFangYunDuan/qrcode/headers.html"
 ["Token"]=>//自定义token及值
 string(12) "token7758521"
 ["X-Requested-With"]=>
 string(14) "XMLHttpRequest"
 ["Accept"]=>
 string(3) "*/*"
 ["User-Agent"]=>
 string(110) "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36"
 ["Origin"]=>
 string(16) "http://localhost"
 ["Connection"]=>
 string(5) "close"
 ["Host"]=>
 string(9) "localhost"
}

4.原始的headers部分数据

["HTTP_COOKIE"]=>
 string(94) "Hm_lvt_f62fa14829605f0d29c05da9c30e045a=1503649309,1503884728; _ga=GA1.1.1091059248.1504832863"
