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

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.

Overview

To import the package:

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

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.
