两个客户端之间的 CURL 请求因超时而失败
CURL request between two clients fails with a timeout
我有两个应用程序，一个 API 及其在 Windows 上的客户端，使用 Nginx，PHP 7.1 使用 Fastcgi。当我从我的 API 向我的客户或从我的客户向我的 API 发送 CURL 请求时，它工作正常。
另一方面，如果 API 向客户端发送请求，客户端也向 API 发送请求，则不再是这种情况。我的第一个请求将在 30 秒后超时，在此期间我无法向客户端并行发送请求。他们都会超时，直到第一个结束。
到目前为止我尝试了什么：
- 我将其添加到我的 Nginx 配置中
fastcgi_read_timeout 120s;
upstream php-cgi {
server 127.0.0.1:9000 max_conns=5 weight=1 max_fails=0 fail_timeout=30s;
server 127.0.0.1:9001 max_conns=5 weight=1 max_fails=0 fail_timeout=30s;
server 127.0.0.1:9002 max_conns=5 weight=1 max_fails=0 fail_timeout=30s;
server 127.0.0.1:9003 max_conns=5 weight=1 max_fails=0 fail_timeout=30s;
server 127.0.0.1:9004 max_conns=5 weight=1 max_fails=0 fail_timeout=30s;
server 127.0.0.1:9005 max_conns=5 weight=1 max_fails=0 fail_timeout=30s;
server 127.0.0.1:9006 max_conns=5 weight=1 max_fails=0 fail_timeout=30s;
server 127.0.0.1:9007 max_conns=5 weight=1 max_fails=0 fail_timeout=30s;
server 127.0.0.1:9008 max_conns=5 weight=1 max_fails=0 fail_timeout=30s;
server 127.0.0.1:9009 max_conns=5 weight=1 max_fails=0 fail_timeout=30s;
server 127.0.0.1:9012 max_conns=5 weight=1 max_fails=0 fail_timeout=30s;
}
以下是我使用的 CURL 选项：
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HEADER => true,
CURLINFO_HEADER_OUT => true,
CURLOPT_ENCODING => '',
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_URL=> MY_URL,
CURLOPT_POSTFIELDS=> MY_DATA,
CURLOPT_CUSTOMREQUEST=> MY METHOD,
CURLOPT_HTTPHEADER=> MY HEADERS
这就是我启动服务器的方式：

感谢这个 link (https://www.nginx.com/resources/wiki/start/topics/examples/fastcgiexample/)，我能够理解有必要在我的启动脚本中定义变量 PHP_FCGI_MAX_REQUESTS 所以 API可以响应同时收到的多个请求。
