WEBrick::HTTPAuth::Htgroup

Htgroup accesses apache-compatible group files. Htgroup can be used to provide group-based authentication for users. Currently Htgroup is not directly integrated with any authenticators in WEBrick. For security, the path for a digest password database should be stored outside of the paths available to the HTTP server.

Example:

htgroup = WEBrick::HTTPAuth::Htgroup.new 'my_group_file'
htgroup.add 'superheroes', %w[spiderman batman]

htgroup.members('superheroes').include? 'magneto' # => false

Public Class Methods

new(path) click to toggle source

Open a group database at path

 
               # File webrick/httpauth/htgroup.rb, line 34
def initialize(path)
  @path = path
  @mtime = Time.at(0)
  @group = Hash.new
  open(@path,"a").close unless File::exist?(@path)
  reload
end
            

Public Instance Methods

add(group, members) click to toggle source

Add an Array of members to group

 
               # File webrick/httpauth/htgroup.rb, line 88
def add(group, members)
  @group[group] = members(group) | members
end
            
flush(output=nil) click to toggle source

Flush the group database. If output is given the database will be written there instead of to the original path.

 
               # File webrick/httpauth/htgroup.rb, line 63
def flush(output=nil)
  output ||= @path
  tmp = Tempfile.new("htgroup", File::dirname(output))
  begin
    @group.keys.sort.each{|group|
      tmp.puts(format("%s: %s", group, self.members(group).join(" ")))
    }
    tmp.close
    File::rename(tmp.path, output)
  rescue
    tmp.close(true)
  end
end
            
members(group) click to toggle source

Retrieve the list of members from group

 
               # File webrick/httpauth/htgroup.rb, line 80
def members(group)
  reload
  @group[group] || []
end
            
reload() click to toggle source

Reload groups from the database

 
               # File webrick/httpauth/htgroup.rb, line 45
def reload
  if (mtime = File::mtime(@path)) > @mtime
    @group.clear
    open(@path){|io|
      while line = io.gets
        line.chomp!
        group, members = line.split(/:\s*/)
        @group[group] = members.split(/\s+/)
      end
    }
    @mtime = mtime
  end
end
