Authentication filter for handling DigestAuth negotiation. Used in WWWAuth.
Authentication scheme.
Creates new DigestAuth filter.
# File lib/httpclient/auth.rb, line 317 def initialize @auth = {} @challenge = {} @set = false @nonce_count = 0 @scheme = "Digest" end
Challenge handler: remember URL and challenge token for response.
# File lib/httpclient/auth.rb, line 364 def challenge(uri, param_str) @challenge[uri] = parse_challenge_param(param_str) true end
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 350 def get(req) target_uri = req.header.request_uri param = Util.hash_find_value(@challenge) { |uri, v| Util.uri_part_of(target_uri, uri) } return nil unless param user, passwd = Util.hash_find_value(@auth) { |uri, auth_data| Util.uri_part_of(target_uri, uri) } return nil unless user calc_cred(req, user, passwd, param) end
Resets challenge state. Do not send ‘*Authorization’ header until the server sends ‘*Authentication’ again.
# File lib/httpclient/auth.rb, line 327 def reset_challenge @challenge.clear end
Set authentication credential. uri == nil is ignored.
# File lib/httpclient/auth.rb, line 333 def set(uri, user, passwd) @set = true if uri uri = Util.uri_dirname(uri) @auth[uri] = [user, passwd] end end
have we marked this as set - ie that it’s valid to use in this context?
# File lib/httpclient/auth.rb, line 342 def set? @set == true end
