5 nginx lua 配置

nginx配置文件加入如下配置

location ~* ^/aa/{
            default_type 'text/plain';
            content_by_lua 'ngx.say("aaaa")
            
            local res = ngx.location.capture("/proxy/http/www.baidu.com/80/EmployeeLeasing/us/user/checkUserLogin.do", {
                method = ngx.HTTP_POST,
                body = body,
                args = {hello = "world"}
            })
            
            for key,val in pairs(res) do
                if type(val) == "table" then
                    ngx.say(key,"=>",table.concat(val,","))
                else
                    ngx.say(key,"=>",val)
                end
            end';
        }

location /proxy/ {
            internal;
            rewrite ^/proxy/(http?)/([^/]+)/(\d+)/(.*)     /$4 break;
            proxy_pass      $1://$2:$3;
        }
