http請(qǐng)求的header中的os_,net_參數(shù)在 php $_SERVER 無法獲取

你試一下apache_request_headers() 函數(shù) 獲取一下看能夠獲取到嗎?

找到原因了
不只是net_，os_,device_開頭的一些參數(shù)，默認(rèn)情況下nginx會(huì)自動(dòng)drop所有帶下劃線的header
需要設(shè)置 underscores_in_headers on;

If you do not explicitly set underscores_in_headers on;, nginx will silently drop HTTP headers with underscores (which are perfectly valid according to the HTTP standard). This is done in order to prevent ambiguities when mapping headers to CGI variables, as both dashes and underscores are mapped to underscores during that process.

謝邀！

<?php
    header('Access-Control-Allow-Origin:*');  
    header('Access-Control-Allow-Credentials: true');
    header('Access-Control-Allow-Methods:GET,PUT,POST,DELETE,OPTIONS');  
    header('Access-Control-Allow-Headers:WWW-Authenticate,Authorization,Set-Cookie,X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5, Content-Type, Date, X-Api-Version'); 
    
    // 獲取頭部信息end
    $header = apache_request_headers();
    
    // 取head標(biāo)簽內(nèi)容
     var_Dump($header);exit;

?> 

獲取的時(shí)候前面要HTTP_：

$_SERVER['HTTP_Authorization']
