1. 示例

只转发GET和POST请求

if ($request_method ~ ^(GET|POST)$ ) {
   proxy_pass http://10.10.239.31:81;
}

不转发POST请求

if ($request_method !~ ^(POST)$ ) {
   proxy_pass http://10.10.239.31:81;
}

PUT请求返回400

if ($request_method !~ ^(PUT)$ ) {
   return 400;
}

2. 完整示例

示例设计

• nginx设置两个service
  • 80端口显示 “port 80”
  • 81端口显示“port 81”
• 80的GET请求转发到81端口
• 80的PUT请求被拒绝

nginx配置

# gzip设置
gzip on;
gzip_vary on;

gzip_comp_level 6;
gzip_buffers 16 8k;

gzip_min_length 1000;
gzip_proxied any;
gzip_disable "msie6";
#gzip_http_version 1.0;
gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript application/javascript;

server {
    listen       80;
    server_name  web80;
    location / {
    if ($request_method ~ ^(GET)$ ) {
       proxy_pass http://10.10.239.31:81;
      }
    if ($request_method ~ ^(PUT)$ ) {
       return 400;
      }
        root   /html1;
        index  index.html index.htm;
        add_header Cache-Control no-store;
    }
}
server {
    listen       81;
    server_name  web81;
    location / {
        root   /html2;
        index  index.html index.htm;
        add_header Cache-Control no-store;
    }
}

postman验证

• GET请求被转发

  
  

  

• PUT请求被拒绝
