nginx按请求类型转发（GET/POST/PUT/DELETE等请求分别转发到不同后端地址）

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
