问题描述
我正在使用curl与PHP来获取API调用的标头响应.
I'm using curl with PHP for getting the header response of an API call.
这是我的代码:
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, 'http://localapi.com/v1/users');
curl_setopt($curl, CURLOPT_HEADER, true);
curl_setopt($curl, CURLOPT_NOBODY, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_TIMEOUT, 10);
curl_setopt($curl, CURLOPT_HTTPHEADER, array("authorization: Basic dmt5MVVTeXg3ZXpKYXVEZGtta2phZThfQ0tXa2tTQkY6"));
$response = curl_exec($curl);
$ response
返回标头:
是否有一种访问单个标头变量(如数组)的方法?
Is there a method for access to the single header variables like an array?
预先感谢您的帮助.
推荐答案
您可以使用 CURLOPT_HEADERFUNCTION .通过为回调提供 $ headers
变量以分配结果,您可以在 curl_exec
完成后将它们作为数组访问.
You can assign a callback for Curl to process the headers in the response using CURLOPT_HEADERFUNCTION. By providing the $headers
variable for the callback to assign the results, you can access them as an array after curl_exec
has finished.
$headers = [];
curl_setopt($curl, CURLOPT_HEADERFUNCTION, function ($ch, $header) use (&$headers) {
$matches = array();
if ( preg_match('/^([^:]+)\s*:\s*([^\x0D\x0A]*)\x0D?\x0A?$/', $header, $matches) )
{
$headers[$matches[1]][] = $matches[2];
}
return strlen($header);
});
curl_exec($curl);
$ headers
现在将包含响应头的关联数组
$headers
will now contain an associative array of the response headers
