Overview

Extensions for em-http so that we can use consumer.sign! with an EventMachine::HttpClient instance. This is purely syntactic sugar.

#normalize_uri ⇒ Object

This code was lifted from the em-http-request because it was removed from the gem June 19, 2010 see: github.com/igrigorik/em-http-request/commit/d536fc17d56dbe55c487eab01e2ff9382a62598b

#oauth!(http, consumer = nil, token = nil, options = {}) ⇒ Object

Add the OAuth information to an HTTP request. Depending on the options[:scheme] setting this may add a header, additional query string parameters, or additional POST body parameters. The default scheme is header, in which the OAuth parameters as put into the Authorization header.

  • http - Configured Net::HTTP instance, ignored in this scenario except for getting host.

  • consumer - OAuth::Consumer instance

  • token - OAuth::Token instance

  • options - Request-specific options (e.g. request_uri, consumer, token, scheme, signature_method, nonce, timestamp)

This method also modifies the User-Agent header to add the OAuth gem version.

#signature_base_string(http, consumer = nil, token = nil, options = {}) ⇒ Object

Create a string suitable for signing for an HTTP request. This process involves parameter normalization as specified in the OAuth specification. The exact normalization also depends on the options[:scheme] being used so this must match what will be used for the request itself. The default scheme is header, in which the OAuth parameters as put into the Authorization header.

  • http - Configured Net::HTTP instance

  • consumer - OAuth::Consumer instance

  • token - OAuth::Token instance

  • options - Request-specific options (e.g. request_uri, consumer, token, scheme, signature_method, nonce, timestamp)
