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" }
