ring-curl

A Clojure library designed to convert ring requests into cURL commands.

It's main purpose is in debugging applications, as it easily allows you to replay requests against services.

Installation

ring-curl is available as a Maven artifact from Clojars.

Usage

(:require [ring-curl.core :as ring-curl])

(ring-curl/to-curl request)

; or with options

(ring-curl/to-curl request {:some-option "the-value"})

Options

The following options can be used to modify the output, see the cURL man page for more details about exactly what each option will do.

• :verbose? A truthy value adds the -v curl flag to the output.

• :very-silent? A truthy value adds the -s curl flag to the output.

• :silent? A truthy value adds the -s and -S curl flags to the output.

• :no-proxy A sequence of strings will add the --noproxy "<vals>" curl flag to the output.

• :progress-bar? A truthy value adds the -# curl flag to the output.

• :insecure? A truthy value adds the -k curl flag to the output.

• :connect-timeout A integer value adds the --connect-timeout <val> curl flag to the output.

• :max-time A integer value adds the -m <val> curl flag to the output.

• :no-buffer? A truthy value adds the -N curl flag to the output.

• :output A string value adds the -o "<val>" and --create-dirs curl flags to the output.

• :retry A interger value adds the --retry <val> curl flag to the output.

• :dump-headers A string value adds the -D "<val>" curl flag to the output.

Middleware

There is middleware included to automatically log every request as curl. This middleware should be the last middleware in the chain, this will ensure the request has been properly modified by all the other middleware.

(require [ring-curl.middleware :refer :all])

(defn handler [request]
  (response {:foo "bar"}))

(def app
  (wrap-curl-logging handler))

Custom writers

You can replace the xml and json writers with your own by binding:

(:require [ring-curl.core :as ring-curl])

(binding [ring-curl/write-json my-custom-function]
  (ring-curl/to-curl request))

(binding [ring-curl/write-xml my-custom-function]
  (ring-curl/to-curl request))

clj-http

If you use clj-http you can use the convert function under the ring-curl.clj-http namespace to convert it to a ring request. This will allow it to be printed correctly as curl by the core namespace.
