    Examples

    # init users database
    user_db = list(
      "user-1" = "password-1",
      "user-2" = "password-2"
    )
    # define authentication handler
    auth_fun = function(user, password) {
      if (is.null(user_db[[user]])) return(FALSE) # not found
      if (!identical(user_db[[user]], password)) return(FALSE) # incorrect
      return(TRUE)
    }
    # init backend
    auth_backend = AuthBackendBasic$new(FUN = auth_fun)
    
    # test backend
    # define credentials (see RFC)
    creds = jsonlite::base64_enc("user-1:password-1")
    # generate request headers
    h = list("Authorization" = sprintf("Basic %s", creds))
    # simulate request
    rq = Request$new(path = "/", headers = h)
    # init response object
    rs = Response$new()
    # perform authentication
    auth_backend$authenticate(rq, rs) # TRUE
