perform_call(uri, method, params, headers) click to toggle source

Actual HTTP call is performed here

# File lib/domoscio_rails.rb, line 143
def self.perform_call(uri, method, params, headers)
  Net::HTTP.start(uri.host, uri.port, use_ssl: uri.scheme == 'https') do |http|

    req.body = DomoscioRails::JSON.dump(params)
    http.request req
  end
end

raise_http_failure(uri, response, params) click to toggle source

This helper will check the response status and build the correcponding DomoscioRails::ResponseError

# File lib/domoscio_rails.rb, line 130
def self.raise_http_failure(uri, response, params)
  return if response.is_a? Net::HTTPSuccess

  raise ResponseError.new(
    uri,
    response.code.to_i,
    DomoscioRails::JSON.load((response.body.nil? ? '' : response.body), symbolize_keys: true),
    response.body, params
  )
end

request(method, url, params={}) click to toggle source

method: HTTP method; lowercase symbol, e.g. :get, :post etc.
url: the part after Configuration#root_url
params: hash; entity data for creation, update etc.; will dump it by JSON and assign to Net::HTTPRequest#body

Performs HTTP requests to Adaptive Engine On token issues, will try once to get a new token then will output a DomoscioRails::ReponseError with details

Raises DomoscioRails::ResponseError on Adaptive Error Status Raises DomoscioRails::ProcessingError on Internal Error

# File lib/domoscio_rails.rb, line 74

request_headers() click to toggle source

Process the token loading and analyze will return the processed headers and a token store flag

# File lib/domoscio_rails.rb, line 183
def self.request_headers
  auth_token = DomoscioRails::AuthorizationToken::Manager.token
  if auth_token && auth_token[:access_token] && auth_token[:refresh_token]
    [false, send_current_tokens(auth_token)]
  else
    [true, request_new_tokens]
  end
rescue SyntaxError, StandardError
  [true, request_new_tokens]
end

request_new_tokens() click to toggle source

If we cant find tokens of they are corrupted / expired, then we set headers to request new ones

# File lib/domoscio_rails.rb, line 206
def self.request_new_tokens
  {
    'user_agent' => DomoscioRails.user_agent.to_s,
    'Authorization' => "Token token=#{DomoscioRails.configuration.client_passphrase}",
    'Content-Type' => 'application/json'
  }
end

retry_call_and_store_tokens(uri, method, params) click to toggle source

This method is called when AdaptiveEngine returns tokens errors Action on those errors is to retry and request new tokens, those new token are then stored

# File lib/domoscio_rails.rb, line 153
def self.retry_call_and_store_tokens(uri, method, params)
  headers = request_new_tokens
  response = perform_call(uri, method, params, headers)
  DomoscioRails::AuthorizationToken::Manager.storage.store({
                                                             access_token: response['Accesstoken'],
                                                             refresh_token: response['Refreshtoken']
                                                           })
  response
end

send_current_tokens(auth_token) click to toggle source

If stored token successfully loaded we build the header with them

# File lib/domoscio_rails.rb, line 196
def self.send_current_tokens(auth_token)
  {
    'user_agent' => DomoscioRails.user_agent.to_s,
    'AccessToken' => auth_token[:access_token].to_s,
    'RefreshToken' => auth_token[:refresh_token].to_s,
    'Content-Type' => 'application/json'
  }
end

send_request(uri, method, params, headers) click to toggle source

This function catches usual Http errors during callsheaders

def self.send_request(uri, method, params, headers)
  response = perform_call(uri, method, params, headers)
  response = retry_call_and_store_tokens(uri, method, params) if %w[401 403].include? response.code
  response
rescue Timeout::Error, Errno::EINVAL, Errno::ECONNREFUSED, Errno::ECONNRESET,
       EOFError, Net::HTTPBadResponse, Net::HTTPHeaderSyntaxError, Net::ProtocolError => e
  ProcessingError.new(uri, 500, e, response)
