<?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" ["http_accept_language"]=> string(14) "zh-cn,zh;q=0.8" ["http_accept_encoding"]=> string(17) "gzip, deflate, br" ["http_referer"]=> string(62) "http://localhost/diannaobengkuifangyunduan/qrcode/headers.html" ["http_token"]=>//自定义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"
