PHP Header 存在但无法检索

Question

我正在使用此方法使 apache header 请求在 nginx 中工作。

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; 
    } 
}

我像这样检索 header $headers = apache_request_headers(); 并使用数组来保存 json。

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

下面的代码是 $response 数组变量中的内容：

error: true

我的问题是，我需要从 $header 中获取 X-ApiKey，但没有使用 $api_key = $headers['X-ApiKey']; returns，但是如您所见，X-ApiKey 存在于 $header。有人可以告诉我我在这里缺少什么吗？

Answer 1

$response["message"] 是一个 string。首先尝试explode它然后访问它-

$temp = explode('X-Apikey:', $response['message']);
$temp1 = explode('X-Http-Proto:', $temp[1]);
var_dump(trim(str_replace('"', '', $temp1[0])));

输出

string(32) "bca0de3e7c10cb6623ef00021caf9450"

Answer 2

您似乎使用了错误的变量名。变量名称区分大小写。

响应returns如下（Apikey中的小k）： X-Apikey: "bca0de3e7c10cb6623ef00021caf9450"

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

尝试以下操作： $api_key = $headers['X-Apikey'];
