为什么简单的PHP Curl https POST请求在Mac机器上需要30秒以上才能完成

Question

我正在用PHP 7.2编写一个API，以与支付平台对接。我在Mac(Catalina(上做这件事，我的项目由Mac上的Nginx(Laravel Valet(反向代理。

最简单的Curl请求需要很长时间才能完成。例如，36秒(仅用于执行curl_exec((函数(，而来自同一台机器的SAME请求使用POSTMAN需要1.7秒。

知道为什么会这样吗？

Curl报告似乎很好(经过消毒(：

这个请求似乎很简单(与POSTMAN的请求相同(：

$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);

读到网上的一些消息，我尝试添加curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);curl_setopt($curl CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );但它不会改变任何事情。。。

非常感谢！E.

你说得绝对正确。在我的案例中，我有一个"错误配置的DNS解析程序"。通过运行代客泊车诊断发现。在我的Mac网络设置中声明了一些过时的DNS。。。

出于某种原因，Postman并不介意，但PHP Curl丢失了。

不过我太笨了。
