Question

我正在尝试从一个本地php页面（a.php）向同一本地另一个php页面（b.php）发送curl请求。我对Nginx完全陌生，真的需要帮助。

nginx.conf

worker_processes  1;

events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  65;

    server {
        listen       80;
        server_name  localhost;

        location / {
            root   html;
            index  index.html index.htm index.php;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
        
        location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }
    }
}

$response = curl_exec($curl);

curl_close($curl);
echo $response;
?>

echo "Test";
exit();

我已经使用了以上nginx配置，将请求从a.php页面发送到b.php页面。在浏览器上运行a.php后，它将继续加载，最后经过很长时间，它会以“发生错误”为响应，并在检查错误时显示“ 504错误”。

您用来启动所有内容的批处理文件将无法像这样...

nginx启动，但从不将控制权返回给脚本。 php-fpm尚未启动。

要将nginx作为服务启动，请在安装文件夹中使用start nginx。

请注意，启动后php-fpm也不会返回。打开一个新的CLI并ping本地主机，或通过浏览器运行a.php，届时该浏览器应该可以正常工作。

在nginx中，如何从本地主机发送响应？
