如何讓laravel 5.4

所有的頭信息，當我打印，如：如何讓laravel 5.4

echo '<pre>'; 
print_r(getallheaders());

它給輸出

)

但是當我打印使用像laravel功能：

print_r($request->header());或print_r($request->headers->all());

它永遠不會打印出我所需的變量在數組中。其打印輸出以下

Array 
(
    [host] => Array 
     (
      [0] => abc.com 
     ) 

    [connection] => Array 
     (
      [0] => keep-alive 
     ) 

    [cache-control] => Array 
     (
      [0] => max-age=0 
     ) 

    [upgrade-insecure-requests] => Array 
     (
      [0] => 1 
     ) 

    [user-agent] => Array 
     (
      [0] => Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36 
     ) 

    [accept] => Array 
     (
      [0] => text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8 
     ) 

    [accept-encoding] => Array 
     (
      [0] => gzip, deflate, sdch 
     ) 

    [accept-language] => Array 
     (
      [0] => en-US,en;q=0.8 
     ) 

    [cookie] => Array 
     (
      [0] => cookie 
     ) 

)

出局我怎麼能打印laravel功能同樣可以用這張getallheaders()做所有的值？

剛因爲你使用的laravel並不意味着你不能使用'getallheaders（）' – nogad

只能在apache上工作 – AndrewMcLagan

是的，或者它是一個別名的函數，apache_request_headers（）。起初，我認爲Laravel正在隱藏一些標題，但顯然不是;我將這些列表並排比較，並且一切都被考慮在內。 –

Laravel使用交響樂，這使子陣列的所有頭值，因此我們就可以映射陣列，並讓他們出來：

$get_first = function($x){ 
    return $x[0]; 
}; 
// Same as getallheaders(), just with lowercase keys 
print_r(array_map($get_first, $request->headers->all()));

注：所有按鍵均爲小寫

是的，這只是使它更難以工作。 –
