NAME

HTTP::Tiny::Plugin::Retry - Retry failed request

VERSION

This document describes version 0.004 of HTTP::Tiny::Plugin::Retry (from Perl distribution HTTP-Tiny-Plugin-Retry), released on 2020-08-14.

SYNOPSIS

use HTTP::Tiny::Plugin 'Retry' => {
    max_attempts => 3, # optional, default 3
    delay        => 2, # optional, default 2
    retry_if     => qr/^[45]/, # optional, default is only 5xx errors are retried
};

my $res  = HTTP::Tiny::Plugin->new->get("http://www.example.com/");

DESCRIPTION

This plugin retries failed response. By default only retries 5xx failures, as 4xx are considered to be client's fault (but you can configure it with "retry_if").

CONFIGURATION

max_attempts

Int. Default 4.

delay

Float.

retry_if

Regex (or scalra), or arrayref, or coderef. If regex or scalar, then will be matched against response status. If array, then will be assumed to be status codes to trigger retry. If coderef, will be called with arguments: ($class, $response) ($class is the plugin class name) and a true return value will trigger retry.

strategy

Algorithm::Backoff::* module name, without the prefix and with optional arguments (see "instantiate_class_with_optional_args" in Module::Load::Util), e.g. "Constant", ["Exponential" => {initial_delay=>2, max_delay=>100}], "Exponential=initial_delay,2,max_delay,100".

If set, will use delay and maximum attempt values from specified Algorithm::Backoff backoff strategry instead of max_attempts and delay.

ENVIRONMENT

HTTP_TINY_PLUGIN_RETRY_MAX_ATTEMPTS

Int.

HTTP_TINY_PLUGIN_RETRY_DELAY

Int.
