Public Instance Methods

challenge(uri, param_str = nil) click to toggle source

Challenge handler: remember URL for response.

# File lib/httpclient/auth.rb, line 295
def challenge(uri, param_str = nil)
  synchronize {
    @challenge[urify(uri)] = true
    true
  }
end
get(req) click to toggle source

Response handler: returns credential. It sends cred only when a given uri is;

  • child page of challengeable(got *Authenticate before) uri and,

  • child page of defined credential

# File lib/httpclient/auth.rb, line 281
def get(req)
  target_uri = req.header.request_uri
  synchronize {
    return nil unless @challenge.find { |uri, ok|
      Util.uri_part_of(target_uri, uri) and ok
    }
    return @cred if @cred
    Util.hash_find_value(@auth) { |uri, cred|
      Util.uri_part_of(target_uri, uri)
    }
  }
end
reset_challenge() click to toggle source

Resets challenge state. Do not send '*Authorization' header until the server sends '*Authentication' again.

# File lib/httpclient/auth.rb, line 250
def reset_challenge
  synchronize {
    @challenge.clear
  }
end
set(uri, user, passwd) click to toggle source

Set authentication credential. uri == nil for generic purpose (allow to use user/password for any URL).

# File lib/httpclient/auth.rb, line 258
def set(uri, user, passwd)
  synchronize do
    if uri.nil?
      @cred = ["#{user}:#{passwd}"].pack('m').tr("\n", '')
    else
      uri = Util.uri_dirname(uri)
      @auth[uri] = ["#{user}:#{passwd}"].pack('m').tr("\n", '')
    end
    @set = true
  end
end
set?() click to toggle source

have we marked this as set - ie that it's valid to use in this context?

# File lib/httpclient/auth.rb, line 271
def set?
  synchronize {
    @set == true
  }
end
