nginx转发post请求

应用场景：

由于项目迁移，旧接口的代码重新部署在了另外一个域名下的项目，比如：

旧接口地址：https://cecshop.com/api/recommend/add

新接口地址：https://capis.com/rec/recommend/add

https://cecshop.com/api/recommend/add 转发到 https://capis.com/rec/recommend/add

现在要求调用旧接口的请求也兼容，nginx配置post请求转发：

server {
        listen       80;
        server_name  cecshop.com;
        charset      utf8;

        location = /api/recommend/add {
            proxy_pass https://capis.com/rec/recommend/add;
        }
    }

还有一种同一个PHP地址但是通过不同的参数来区分的情况，例如：

https://cecshop.com/api/recommend/alipay.php?act=is_set 转发到 http://capis.com/rec/recommend/alipayset

https://cecshop.com/api/recommend/alipay.php?act=update_info 转发到 http://capis.com/rec/recommend/alipayupdate

这种要用map来配置，$arg_act就是GET请求参数act的值，map根据$arg_act的值赋值给$proxyuri变量：

http {

    map $arg_act  $proxyuri {
        "is_set"       rec/recommend/alipayset;
        "update_info"  rec/recommend/alipayupdate;
    }

    server {
        
        listen       80;
        server_name  cecshop.com;
        charset      utf8;

        location = /api/recommend/alipay.php {
             proxy_pass http://capis.com/$proxyuri;
        }
    }
}
