192.168.32.154 配置反向代理:

     location /api {

                            proxy_pass    http://120.55.118.6:3000;

                            proxy_redirect default ;

                 }

120.55.118.6:3000 对应的接口:

 get '/api/ipsearch' => sub {

 my $c = shift;

  my  $ip=$c->param('ip');

  if ($ip){

use LWP::UserAgent;

my  $ua = LWP::UserAgent->new;

 my $host = "http://ip.taobao.com/service/getIpInfo.php?ip=$ip";

my $request = HTTP::Request->new(GET=>"$host");

my $response = $ua->request($request);

my  $content= $response->decoded_content;

 $content =~ s/\\u([0-9a-fA-F]{4})/pack("U",,hex($1))/eg;

  $content=encode(utf8,$content);

  $json_out       = decode_json($content);

 $c->render(json =>  $json_out->{data} );

				   };

				    };

对比haproxy 的反向代理:

        acl             api_req                 path_beg                -i                      /api
