I wrote the below code

    def decorator(func):
        def wrapper(**kargs):
            for (key, value) in vkargs.iteritems():
                if (key not in kargs):
                    abort(403, ('Missing    parameter:    %s' % key))
                try:
                    kargs[key] = value(kargs[key])
                except ValueError:
                    abort(403, ('Wrong    parameter    format    for:    %s' % key))
            return func(**kargs)
        return wrapper
    return decorator
