PHP cURL不返回响应，POSTMAN返回响应

Question

我正在运行一个看起来像这样的cURL请求

$curl = curl_init();
    curl_setopt_array($curl, array(
        CURLOPT_URL => $url,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_ENCODING => "",
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_TIMEOUT => 30,
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
        CURLOPT_CUSTOMREQUEST => "GET",
        CURLOPT_HTTPHEADER => array(
            "Content-Type: application/json",
            "Authorization: Bearer " . $token
        )
    ));
    $response = curl_exec($curl);
    die(var_dump($response));

我的cURL在PHP中是否不返回任何响应？
