SimpleHttpService

SimpleHttpService is a simple Ruby library to make HTTP requests with customizable options for headers, timeouts, and retries. It provides a convenient way to create and send HTTP requests using a clean and simple interface.

Add this line to your application's Gemfile:

gem 'simple_http_service'

And then execute:

bundle install

Or install it yourself as:

gem install simple_http_service

You can create a new HTTP client using the SimpleHttpService.new method, which initializes an instance of SimpleHttpService::Client.

require 'simple_http_service'

client = SimpleHttpService.new(
  url: 'https://api.example.com/endpoint',
  http_method: :get,
  headers: {
    accept: 'application/json',
    authorization: 'Bearer your_token',
    content_type: 'application/json',
    cookie: 'your cookie'
  },
  open_timeout: 5,
  read_timeout: 10,
  write_timeout: 5,
  max_retries: 3,
  additional_headers: {
    'X-Request-Id': '12345'
  }
)

After creating the client, you can call the call method to make the HTTP request:

response = client.call
puts response.body

• url (required): The URL for the HTTP request.
• http_method (required): The HTTP method to use (:get, :post, :put).
• headers: A hash of headers to include in the request.
• open_timeout: Timeout for opening the connection (default is false).
• read_timeout: Timeout for reading the response (default is false).
• write_timeout: Timeout for writing the request (default is false).
• max_retries: The number of times to retry the request in case of failure.
• request_body: The body of the request (used for POST and PUT requests).
• additional_headers: Additional headers to include in the request.

Here's a complete example of using SimpleHttpService to make a GET request:

require 'simple_http_service'

client = SimpleHttpService.new(
  url: 'https://api.example.com/endpoint',
  http_method: :get,
  headers: {
    accept: 'application/json',
    authorization: 'Bearer your_token'
  },
  open_timeout: 5,
  read_timeout: 10
)

response = client.call
puts response.body

For a POST request with a request body:

require 'simple_http_service'

client = SimpleHttpService.new(
  url: 'https://api.example.com/endpoint',
  http_method: :post,
  headers: {
    accept: 'application/json',
    authorization: 'Bearer your_token',
    content_type: 'application/json'
  },
  request_body: { key: 'value' }.to_json,
  open_timeout: 5,
  read_timeout: 10,
  write_timeout: 5
)

response = client.call
puts response.body

The library defines a custom error class SimpleHttpService::Error that you can use to handle exceptions:

begin
  response = client.call
  puts response.body
rescue SimpleHttpService::Error => e
  puts "An error occurred: #{e.message}"
end

After checking out the repo, run bin/setup to install dependencies. Then, run rspec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle install. To release a new version, update the version number in version.rb.
