nginx的conf文件，两种配置方式，第一种无ssl证书，第二种有ssl证书。

以下为无ssl证书配置的请求转发

server {
    listen 80;
    server_name api.******.com;
    location ~* /union {
      client_max_body_size   3000m;
      proxy_next_upstream http_502 http_504 error timeout invalid_header;

      proxy_set_header   Host $host;
      proxy_set_header   X-Real-IP $remote_addr;
      proxy_set_header   X-Real-PORT $remote_port;
      proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;

      proxy_pass http://127.0.0.1:8080;
      proxy_redirect default;
      proxy_connect_timeout 3000;

      if ($http_origin ~ https://(.*).******.com){
          set $allow_url $http_origin;
      }

      if ($request_method = OPTIONS) {
          add_header Access-Control-Allow-Methods "GET, POST, PUT, DELETE, OPTIONS, HEAD";
#         add_header Access-Control-Allow-Origin $allow_url;
          add_header Access-Control-Allow-Origin *;
          add_header Access-Control-Allow-Headers "Cookie,Set-Cookie,Origin,X-Requested-With,token,authorization,Accept,Content-type";
          add_header Access-Control-Allow-Credentials "true";
          add_header Content-Type "text/plain; charset=utf-8";
          add_header Content-Length 0;
        return 204;
      }
    }
}

　　

以下为有ssl请求转发

将以下代码替换成自己的证书路径：

ssl_certificate /etc/nginx/cert/api.pem;
ssl_certificate_key /etc/nginx/cert/api.key;

server {
    listen 80;
    server_name api.******.com;
    rewrite ^(.*)$ https://${server_name}$1 permanent;
}

server {
    listen 443;
    server_name api.******.com;
    ssl on;
    ssl_certificate   /etc/nginx/cert/api.pem;
    ssl_certificate_key  /etc/nginx/cert/api.key;
    ssl_session_timeout 5m;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    location ~* /union {
      client_max_body_size   3000m;
      proxy_next_upstream http_502 http_504 error timeout invalid_header;

      proxy_set_header   Host $host;
      proxy_set_header   X-Real-IP $remote_addr;
      proxy_set_header   X-Real-PORT $remote_port;
      proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;

      proxy_pass http://127.0.0.1:8080;
      proxy_redirect default;
      proxy_connect_timeout 3000;

      if ($request_method = OPTIONS) {
          add_header Access-Control-Allow-Methods "GET, POST, PUT, DELETE, OPTIONS, HEAD";
          add_header Access-Control-Allow-Origin *;
          add_header Access-Control-Allow-Headers "Cookie,Set-Cookie,Origin,X-Requested-With,token,authorization,Accept,Content-type";
          add_header Access-Control-Allow-Credentials "true";
          add_header Content-Type "text/plain; charset=utf-8";
          add_header Content-Length 0;
        return 204;
      }
    }
}
