下面小編就為大家分享一篇php獲取ajax的headers方法與內(nèi)容實例，具有很好的參考價值，希望對大家有所幫助。一起跟隨小編過來看看吧

1.前端頁面

<!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">點擊</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，請使用JSON.stringify(setting.data)
type: 'POST',
//dataType: 'json',
//contentType: 'application/json',
//processData: true,//為true不會序列化數(shù)據(jù)
beforeSend: function () {
// layer.load(2);
},
headers: {
"token":'token7758521'//自定義token及值
},
success: function (responseData) {
console.log(responseData);
},
error: function (error) {
console.log(error);
}
});
});
</script>
</body>

2.php頁面

<?php
$arr = get_getallheaders();//獲取http頭數(shù)組
//echo $arr["Token"];//輸出Token
var_dump($arr);//輸出整個數(shù)組
function get_getallheaders() //定義方法
{ 
 foreach ($_SERVER as $name => $value) //循環(huán)_SERVER數(shù)組
 { 
 if (substr($name, 0, 5) == 'HTTP_') //前5個字符是HTTP_的進入循環(huán)
 { 
 $headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))))] = $value; 
 //注釋
 //substr($name, 5)，從$name第5個字符向后截取
 //str_replace('_', ' ',)下劃線替換成空格
 //strtolower()全部轉(zhuǎn)換為小寫
 //ucwords()首字母轉(zhuǎn)換為大寫
 //str_replace(' ', '-',)所有空格替換為-
 } 
 } 
 return $headers; //返回前key前5個字符是HTTP_的數(shù)組
 //return $_SERVER; //返回_SERVER數(shù)組
}

3.php頁面返回的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"]=>//自定義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部分數(shù)據(jù)

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

 ["HTTP_ACCEPT_ENCODING"]=>
 string(17) "gzip, deflate, br"
 ["HTTP_REFERER"]=>
 string(62) "http://localhost/DianNaoBengKuiFangYunDuan/qrcode/headers.html"
 ["HTTP_TOKEN"]=>//自定義token及值
 string(12) "token7758521"
 ["HTTP_X_REQUESTED_WITH"]=>
 string(14) "XMLHttpRequest"
 ["HTTP_ACCEPT"]=>
 string(3) "*/*"
 ["HTTP_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"
 ["HTTP_ORIGIN"]=>
 string(16) "http://localhost"
 ["CONTENT_LENGTH"]=>
 string(1) "7"
 ["HTTP_CONNECTION"]=>
 string(5) "close"
 ["HTTP_HOST"]=>
 string(9) "localhost"
