o #`^h @sddlZddlmZmZmZmZddlmZmZddl m Z m Z ddl m Z ddlmZddlmZd Zero }|s Jdtdtdtdtffdd }|S)aFactory for producing a middleware that normalizes the path of a request. Normalizing means: - Add or remove a trailing slash to the path. - Double slashes are replaced by one. The middleware returns as soon as it finds a path that resolves correctly. The order if both merge and append/remove are enabled is 1) merge slashes 2) append/remove slash 3) both merge slashes and append/remove slash. If the path resolves with at least one of those conditions, it will redirect to the new path. Only one of `append_slash` and `remove_slash` can be enabled. If both are `True` the factory will raise an assertion error If `append_slash` is `True` the middleware will append a slash when needed. If a resource is defined with trailing slash and the request comes without it, it will append it automatically. If `remove_slash` is `True`, `append_slash` must be `False`. When enabled the middleware will remove trailing slashes and redirect if the resource is defined If merge_slashes is True, merge multiple consecutive slashes in the path into one. z#Cannot both remove and append slashrhandlerrcs0t|jjtrg}d|jvr|jdd\}}d|}nd}|j}r.|tdd|r=|j ds=||drN|j drN||ddr^r^|tdd|drrrrtdd|}||dd|D]}tdd|}t ||IdH\}}|r|j|qt||IdHS)N?rz//+/z^//+) isinstancerrouter raw_pathsplitappendresubrendswithr )rr'paths_to_checkrquerymerged_slashesresolvesr#r%r&r$rrimplLs4  z'normalize_path_middleware..implrr rr )r#r$r%r&correct_configurationr9rr8rr&s # "rrrcs"tdtdtdtffdd }|S)Nrr'rcs@|j||IdHWdS1swYdS)N)rset_current_app)rr'rrrr9os $z&_fix_request_current_app..implr:)rr9rr=r_fix_request_current_appnsr>)r1typingrrrrtypedefsrrweb_exceptionsr r web_requestr web_responser web_urldispatcherr __all__web_apprrstrboolr rrr>rrrrs:      H
