从 cURL 获取 CURLOPT_HTTPHEADER 的值

Question

我有下面的方法是使用cURL从网络服务器获取响应。function login (string $_login, string $_password) : string {    $url = "https://acweb.net.br/api/orcamentos/login";      $fields = [        "login"    => $_login,        "password" => $_password    ];    $headers = [        "Try" => "Trying"    ];    $ch = curl_init();    curl_setopt( $ch, CURLOPT_URL, $url);    curl_setopt( $ch, CURLOPT_POST, true);    curl_setopt( $ch, CURLOPT_POSTFIELDS, $fields);    curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true);    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);    return curl_exec( $ch );}它工作正常！我可以得到$_POST的值print_r ($_POST)但我无法获得CURLOPT_HTTPHEADER的值。编辑：我确实尝试过：print_r ($_SERVER)但它不在那里。如何获得CURLOPT_HTTPHEADER的值？$_SERVER中的所有HTTP_headers：[HTTP_HOST] => ctemcasb.com.br[HTTP_CONNECTION] => keep-alive[HTTP_UPGRADE_INSECURE_REQUESTS] => 1[HTTP_USER_AGENT] => Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36[HTTP_SEC_FETCH_USER] => ?1[HTTP_ACCEPT] => text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3[HTTP_SEC_FETCH_SITE] => none[HTTP_SEC_FETCH_MODE] => navigate[HTTP_ACCEPT_ENCODING] => gzip, deflate, br[HTTP_ACCEPT_LANGUAGE] => pt-BR,pt;q=0.9,en-US;q=0.8,en;q=0.7[HTTP_COOKIE] => PHPSESSID=j4cqqdc83fia68nk0gsglqk1bvHTTP_TRY，不存在。现在？我在服务器上做了这个：print_r($_SERVER)和print_r ($_SERVER["HTTP_TRY]);

Answer 1

标头不应该是关联数组，它应该是字符串的索引数组。

$headers = [

    'Try: Trying',

    'Content-Type: text/html',

    ...

]; 

然后你应该能够访问标题：$_SERVER['HTTP_TRY']因为自定义标题的前缀是HTTP_
