      (nil)

  • #initialize(credentials: ) ⇒ Signer

    Parameters:

  • #initialize(credentials_provider: ) ⇒ Signer

    Parameters:

    • :credentials_provider (#credentials) —

      An object that responds to ‘#credentials`, returning an object that responds to:

      • ‘#access_key_id`

Instance Method Details

#sign_request(request) ⇒ Hash

Computes a version 2 signature. The signature is returned as a hash of request parameters that should be applied to the HTTP request. The given request will not be modified.

signature = signer.sign_request(
  http_method: 'POST',
  url: 'https://domain.com',
  params: {
    'Param.Name' => 'Param.Value',
  }
)

# Returns a hash with the following keys:
signature['AWSAccessKeyId']
signature['SecurityToken'] # when using session credentials
signature['Timestamp']
signature['SignatureVersion']
signature['SignatureMethod']
signature['Signature']

Parameters:

  • request (Hash)

Options Hash (request):

  • :http_method (required, String) —

    One of ‘GET’, ‘HEAD’, ‘PUT’, ‘POST’, ‘PATCH’, or ‘DELETE’

  • :url (required, String, URI::HTTPS, URI::HTTP) —

    The request URI. Must be a valid HTTP or HTTPS URI.

  • :params (optional, Hash) — default: {} —

    Request parameters to sign. This should be a hash with un-escaped parameter names and values. For “GET” style requests, this should be the querystring parameters. For “POST” style requests, this should be the form-url-encoded query parameters.

Returns:

  • (Hash) —

    Returns a hash of un-escaped signature parameters. These must be applied to the HTTP request. If the request is a “GET” request, they should be applied to the querystring. If the request is “POST” then they should be added to the form-url-encoded HTTP request body.
