php - 为什么简单的 PHP Curl https POST 请求需要 30 多秒才能从 Mac 机器上完成？

Question

我正在用 PHP 7.2 编写 API 以与支付平台交互。我在 Mac (Catalina) 上执行此操作，我的项目由 Mac 上的 Nginx (Laravel Valet) 反向代理。
最简单的 Curl 请求需要永远完成。例如，36 秒(仅用于执行 curl_exec() 函数)，当来自同一台机器的 SAME 请求使用 POSTMAN 时需要 1.7 秒。
知道为什么会这样吗？
Curl 报告似乎很好(已 sanitizer ):

这个请求看起来很简单(和 POSTMAN 一模一样):

$curl = curl_init();
        $header = array(
            'Accept-Language: en_US',
            'Accept: application/json'
        );
        curl_setopt_array($curl, array(
            CURLOPT_URL             => VB_P['API_URL'].'/v1/oauth2/token',
            CURLOPT_RETURNTRANSFER  => true,
            //CURLOPT_HEADER          => 'Accept: application/json',
            CURLOPT_HTTPHEADER      => $header,
            //CURLOPT_HEADER        => 'Accept-Language: en_US',
            CURLOPT_ENCODING        => "",
            CURLOPT_MAXREDIRS       => 10,
            CURLOPT_TIMEOUT         => 0,
            CURLOPT_FOLLOWLOCATION  => true,
            CURLOPT_HTTP_VERSION    => CURL_HTTP_VERSION_1_1,
            CURLOPT_CUSTOMREQUEST   => "POST",
            CURLOPT_POSTFIELDS      => "grant_type=client_credentials",
            CURLOPT_USERPWD         => VB_P['CLIENT_ID'].':'.VB_P['CLIENT_SECRET']
        ));

        if (VB_SERV_NAME == 'local') {
            curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        }

        $time_start = microtime(true);
        $response_json = curl_exec($curl);
        $time_end = microtime(true);

看了网上的一些帖子，我试着加了 curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);curl_setopt($curl CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );但它不会改变任何东西......
非常感谢!

你是绝对正确的。就我而言，我有一个“错误配置的 DNS 解析器”。通过运行 Valet 诊断发现。在我的 Mac 网络设置中声明了一些过时的 DNS...
不知为何，Postman 并不介意，但 PHP Curl 却丢失了。
虽然我很笨。
