Current available solutions to find Brazilian addresses by zipcode use an HTML form from Correios web site website to perform it, instead of to use a real API.

The old solution works with an HTTP request to the form, followed by parsing HTML result page. The huge problem here is when the Correios web site development team decides to modify some HTML element in the result page, even a layout update, it will break the parser logic for result.

Correios CEP gem solves this problem, retrieving data directly from Correios database.

Installing

Gemfile

gem 'correios-cep'

Direct installation

$ gem install correios-cep

Using

require 'correios-cep'

# With "get" instance method
finder = Correios::CEP::AddressFinder.new
address = finder.get('54250610')

# With "get" class method
address = Correios::CEP::AddressFinder.get('54250610')

address # =>
{
  :address => 'Rua Fernando Amorim',
  :neighborhood => 'Cavaleiro',
  :city => 'JaboatΓ£o dos Guararapes',
  :state => 'PE',
  :zipcode => '54250610',
  :complement => ''
}

Configurations

All the configurations are set using Correios::CEP module.

Timeout

For default, the timeout for a request to Correios Web Service is 5 seconds. If Correios Web Service does not respond, a HTTP::TimeoutError exception will be raised.

Correios::CEP.configure do |config|
  config.request_timeout = 3 # It configures timeout to 3 seconds
end

HTTP Proxy

If you need to use an HTTP proxy to HTTP requests, configure HTTP proxy URL.

Correios::CEP.configure do |config|
  config.proxy_url = 'http://10.20.30.40:8888'
end

Log

From 0.7.0 version, there is no more default logger, and the log level will be the same of the given logger.

Correios::CEP.configure do |config|
  config.logger = Rails.logger
end

Configuration example

Correios::CEP.configure do |config|
  config.logger = Rails.logger
  config.request_timeout = 3 # seconds
end
