Rabbit Hole, a RabbitMQ HTTP API Client for Go

This library is a RabbitMQ HTTP API client for the Go language.

Supported Go Versions

Rabbit Hole supports the last 2 stable Go versions, as well as the version in development (a.k.a. master).

Supported RabbitMQ Versions

  • RabbitMQ 3.8.x is the primary target series
  • Almost all API endpoints work against RabbitMQ 3.7.x nodes but some metrics and stats may be missing
  • RabbitMQ 3.7.x is out of general support

All versions require RabbitMQ Management UI plugin to be installed and enabled.

Project Maturity

Rabbit Hole is a mature library (first released in late 2013) designed after a couple of other RabbitMQ HTTP API clients with stable APIs. Breaking API changes are not out of the question but not without a reasonable version bump.

It is largely feature complete and decently documented.

Change Log

If upgrading from an earlier release, please consult with the change log.

Installation

go get github.com/michaelklishin/rabbit-hole/v2

# or, for v1.x:
# go get github.com/michaelklishin/rabbit-hole

API Reference

API reference is available on godoc.org.

Overview

To import the package:

import (
       "github.com/michaelklishin/rabbit-hole/v2"
)

All HTTP API operations are accessible via rabbithole.Client, which should be instantiated with rabbithole.NewClient:

// URI, username, password
rmqc, _ = NewClient("http://127.0.0.1:15672", "guest", "guest")

TLS (HTTPS) can be enabled by adding an HTTP transport to the parameters of rabbithole.NewTLSClient:

transport := &http.Transport{TLSClientConfig: tlsConfig}
rmqc, _ := NewTLSClient("https://127.0.0.1:15672", "guest", "guest", transport)

RabbitMQ HTTP API has to be configured to use TLS.
