我们从Python开源项目中，提取了以下50个代码示例，用于说明如何使用werkzeug._internal._encode_idna()。
def bind(self, server_name, script_name=None, subdomain=None, url_scheme='http', default_method='GET', path_info=None, query_args=None): """Return a new :class:`MapAdapter` with the details specified to the call.

While this doesn't really make sense for manual bind calls, it's useful if you bind a map to a WSGI environment which already contains the path info. `subdomain` will default to the `default_subdomain` for this map if no defined.
