Question

我正在使用此方法在nginx中使apache头请求工作。

if (!function_exists('apache_request_headers')) { 
    function apache_request_headers() { 
        foreach($_SERVER as $key=>$value) { 
            if (substr($key,0,5)=="HTTP_") { 
                $key=str_replace(" ","-",ucwords(strtolower(str_replace("_"," ",substr($key,5))))); 
                $out[$key]=$value; 
            }else{ 
                $out[$key]=$value; 
            } 
        } 
        return $out; 
    } 
}

我像$headers = apache_request_headers();那样检索标题并使用数组来保存json。

$response=array()
$response["error"] = true;
$response["message"] = $headers;

下面的代码是$ response数组变量的内容：

我的问题是，我需要从$ header中抓取X-ApiKey，但使用$api_key = $headers['X-ApiKey'];不会返回任何内容，但正如您所见，X-ApiKey中存在$header。有人可以告诉我我在这里失踪了吗？

Answer 1

string是explode。首先尝试$temp = explode('X-Apikey:', $response['message']); $temp1 = explode('X-Http-Proto:', $temp[1]); var_dump(trim(str_replace('"', '', $temp1[0])));然后访问它 -

string(32) "bca0de3e7c10cb6623ef00021caf9450"

<强>输出

{{1}}

Answer 2

看起来您使用的是错误的变量名称。变量名称区分大小写。

响应返回以下内容（Apikey中的小k）： X-Apikey: "bca0de3e7c10cb6623ef00021caf9450"

当您使用大写k $api_key = $headers['X-ApiKey'];

时

尝试以下方法： $api_key = $headers['X-Apikey'];

PHP标头存在但无法检索
