两个客户端之间的CURL请求因超时而失败

标签: php nginx curl fastcgi fpm

我有两个应用程序,一个API及其在Windows上的客户端,以及Nginx和带有Fastcgi的PHP 7.1。当我从API向客户端或从客户端向API发送CURL请求时,它可以正常工作。

另一方面,例如,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。他们都会一直超时直到第一个结束。

到目前为止我尝试过的事情:

  • 我将此添加到了Nginx配置
     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

这是我启动服务器的方式:

c:\nginx\RunHiddenConsole.exe c:\nginx\php-7.1\php-cgi.exe -b 127.0.0.1:9005 -c c:\nginx\php-7.1\php.ini
c:\nginx\RunHiddenConsole.exe c:\nginx\php-7.1\php-cgi.exe -b 127.0.0.1:9007 -c c:\nginx\php-7.1\php.ini
c:\nginx\RunHiddenConsole.exe c:\nginx\nginx.exe

还有我的Nginx配置:

多亏了这个链接 (https://www.nginx.com/resources/wiki/start/topics/examples/fastcgiexample/),我才明白有必要在我的启动脚本中定义变量 PHP_FCGI_MAX_REQUESTS 以便 API 可以响应同时收到的多个请求。

SET PHP_FCGI_CHILDREN=5
SET PHP_FCGI_MAX_REQUESTS=0

c:\nginx\RunHiddenConsole.exe c:\nginx\php-7.1\php-cgi.exe -b 127.0.0.1:9005 -c c:\nginx\php-7.1\php.ini
