    use Nginx;
    use Nginx::HTTP;

    ngx_http "1.2.3.4:80", "GET / HTTP/1.1"   . "\x0d\x0a" .
                           "Host: localhost"  . "\x0d\x0a" .
                           ""                 . "\x0d\x0a"   , sub {

        my ($headers, $buf_ref) = @_;

        unless ($headers) {
            ngx_log_error $!, "error";
            return;
        }

        ngx_log_notice 0, "got $headers->{'_status'}";
        ...
    };

Fast and simple asynchronous http client for nginx-perl. Supports keepalive.

    ngx_http
    ngx_http_client

Establishes new connection with $ip:$port and sends raw HTTP request. $request should be either scalar or scalar reference. Additionally there are two options available: timeout and ssl. E.g.:

    ngx_http "1.2.3.4:443:ssl=1;timeout=15", ...
    ngx_http "1.2.3.4:80:timeout=15", ...
    ngx_http "1.2.3.4:80", ...

Calls back with parsed response header in $_[0] and scalar reference to the body in $_[1].

    $headers =  {  _status        => 503,
                   content-type   => ['text/html'],
                   content-length => [1234],
                   ...                              };

    $body = \"foobar";

$body is cleared right after the callback, so you have to copy its content if you want to use it later.

On error calls back without any arguments. Tries to reconnect on the next request.

For now every connection is cached forever. But you can use ngx_http_client to create desired caching behaviour.

    ngx_http "1.2.3.4:80", "GET / HTTP/1.1"   . "\x0d\x0a" .
                           "Host: localhost"  . "\x0d\x0a" .
                           ""                 . "\x0d\x0a"   , sub {

        my ($headers, $body_ref) = @_;

        unless ($headers) {
            ngx_log_error $!, "error";
            return;
        }

        ngx_log_notice 0, "got $headers->{'_status'}";
        ...
    };
