XSR - eXtremely Simple REST client

XSR is an extremely simple REST client aimed to use against JSON/REST APIs.

Installation

Simply run

$ gem install xsr

Using Rails?

Add the following line to your Gemfile:

gem 'xsr'

Usage

Create a new instance of XSR client specifying the base_url for wich you will be requesting further paths:

require 'xsr'
client = XSR::Client.new

And then invoke a service:

resp = client.get('http://api.something.io')
resp.success?
#=> true
resp.body
#=> JSON response as a Ruby Hash Object

Supported HTTP verbs

Implemented verbs are GET, POST, PUT and DELETE. To change the verb simply invoke the corresponding method:

HTTP GET

This will make a HTTP GET request to http://api.something.io

client.get('http://api.something.io')

HTTP POST

This will make a HTTP POST request to http://api.something.io

client.post('http://api.something.io')

HTTP PUT

This will make a HTTP PUT request to http://api.something.io

client.put('http://api.something.io')

HTTP DELETE

This will make a HTTP DELETE request to http://api.something.io

client.delete('http://api.something.io')

Using query string arguments

This will make a HTTP GET request to http://api.somthing.io?arg1=a&arg2=b

client.get('http://api.something.io', args: {arg1: 'a', arg2: 'b'})

Passing JSON arguments in request body

req = { some_key: some_value, other_key: [1,2,3] }
client.post('http://api.something.io', body: req)

Using HTTP headers

This will make a HTTP GET request to http://api.somthing.io passing 'Some-Header: Some-Value' in the HTTP headers

resp = client.get('http://api.something.io', header: {some_header: 'some_value'})

Response object

HTTP response comes in the form of a XSR::Response object:

resp = client.post('http://api.something.io')

resp.success?
#=> Response status code is 2xx

resp.bad_request?
#=> Response status code is 400

resp.unauthorized?
#=> Response status code is 401

resp.forbidden?
#=> Response status code is 403

resp.not_found?
#=> Response status code is 404

resp.server_error?
#=> Response status code is 500

resp.body
#=> JSON response as a Ruby Hash object

resp.http_response
#-> Call http_response to get full Net::HTTPResponse object

SSL considerations

By default, XSR verifies the SSL certificate for the requested server.

To use a custom CA Root certificate set ca_file

client = XSR::Client.new(ca_file: '/path/to/my_custom.pem')
client.get('https://api.something.io/get')

In case you want to skip this verfication, set skip_cert_check:

client = XSR::Client.new(skip_cert_check: true)
client.get('https://api.something.io/get')

What's next?

I'm not planning to add more features right now, but feel free to fork this repo and add any extra functionality you consider that should be included. Please, submit a PR with proposed changes or fixes. Just keep in mind a minimalist paradigm (https://youtu.be/tXVr2E1vfmk).
