Basic Authentication for WEBrick
Use this class to add basic authentication to a WEBrick
servlet.
Here is an example of how to set up a BasicAuth:
config = { :Realm => 'BasicAuth example realm' } htpasswd = WEBrick::HTTPAuth::Htpasswd.new 'my_password_file' htpasswd.set_passwd config[:Realm], 'username', 'password' htpasswd.flush config[:UserDB] = htpasswd basic_auth = WEBrick::HTTPAuth::BasicAuth.new config
Used by UserDB
to create a basic password entry
# File webrick/httpauth/basicauth.rb, line 43 def self.make_passwd(realm, user, pass) pass ||= "" pass.crypt(Utils::random_string(2)) end
Creates a new BasicAuth
instance.
See WEBrick::Config::BasicAuth for default configuration entries
You must supply the following configuration entries:
The name of the realm being protected.
A database of usernames and passwords. A WEBrick::HTTPAuth::Htpasswd
instance should be used.
# File webrick/httpauth/basicauth.rb, line 61 def initialize(config, default=Config::BasicAuth) check_init(config) @config = default.dup.update(config) end
Authenticates a req
and returns a 401 Unauthorized using res
if the authentication was not correct.
# File webrick/httpauth/basicauth.rb, line 70 def authenticate(req, res) unless basic_credentials = check_scheme(req) challenge(req, res) end userid, password = basic_credentials.unpack("m*")[0].split(":", 2) password ||= "" if userid.empty? error("user id was not given.") challenge(req, res) end unless encpass = @userdb.get_passwd(@realm, userid, @reload_db) error("%s: the user is not allowed.", userid) challenge(req, res) end if password.crypt(encpass) != encpass error("%s: password unmatch.", userid) challenge(req, res) end info("%s: authentication succeeded.", userid) req.user = userid end
