We rely on this implementation rather than the one in Python's stdlib, because: * It provides more complete URL validation. * It properly differentiates between an empty querystring and an absent querystring, to distinguish URLs with a trailing '?'. * It handles scheme, hostname, port, and path normalization. * It supports IDNA hostnames, normalizing them to their encoded form. * The API supports passing individual components, as well as the complete URL string. Previously we relied on the excellent `rfc3986` package to handle URL parsing and validation, but this module provides a simpler alternative, with less indirection required. ) annotationsN) InvalidURLizBABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-._~z !$&'()*+,;=z%[A-Fa-f0-9]{2}z(?:(?P{scheme}):)?(?://(?P{authority}))?(?P{path})(?:\?(?P{query}))?(?:#(?P{fragment}))?z([a-zA-Z][a-zA-Z0-9+.-]*)?z[^/?#]*z[^?#]*z[^#]*z.*scheme authoritypathqueryfragmentzA(?:(?P{userinfo})@)?(?P{host}):?(?P{port})?z(\[.*\]|[^:@]*))userinfohostportz[^@]*z(\[.*\]|[^:]*))rrr r r r r rz ^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+$z^\[.*\]$ceZdZUded<ded<ded<ded<ded<ded <ded <edd Zedd Zdd ZddZy) ParseResultstrrr r int | Nonerr str | Noner r cdj|jr|jdndd|jvrd|jdn |j|jd|jgSdgS)N@:[])joinr r rselfs ]/var/www/html/ai-video-generator/backend/venv/lib/python3.12/site-packages/httpx/_urlparse.pyrzParseResult.authorityjszww'+}}4==/#"$'499$4!DII;a $))#'99#8!DII;   ?A   cdjd|jvrd|jdn |j|jd|jgSdgS)Nrrrr)rr rrs rnetloczParseResult.netloctsdww$'499$4!DII;a $))#'99#8!DII;   ?A   rc |s|S|j|j|j|j|jd}|j |t di|S)Nrr)rrr r r updateurlparse)rkwargsdefaultss r copy_withzParseResult.copy_with}sRKkkIIZZ   'h''rc|j}dj|jr|jdnd|rd|nd|j|jd|jnd|j d|j gSdgS)Nrr//?#)rrrr r r )rrs r__str__zParseResult.__str__sNN ww%)[[4;;-q!b$-"YK 2 $(JJ$:!DJJ< '+}}'@!DMM?#    GI    rN)returnr)r%rr-r) __name__ __module__ __qualname____annotations__propertyrr r'r,rrrrasX KM I  I       (  rrc Nt|tkDr tdtd|Dr7t d|D}|j |}d|d|d}t|d|vr%|d}t |tr t|n||d<d|vr0|jdxsd }|jd \|d <}|d<d |vsd |vrLt|jd d xsd }t|jd d xsd } | r|d | n||d<d|vr7|jdxsd } | jd\|d<} |d<| sd|d<d |vrD|jd xsd } d | vr+| jdr| jds d| d|d <|jD]\} }| t|tkDrtd| dtd|Dr:t d|D}|j |}d| d|d|d}t|t | j#|rtd| dt$j'|}|J|j)}|jd|dxsd }|jd|dxsd }|jd|dxsd }|jd|d}|jd|d}t*j'|}|J|j)}|jd|dxsd }|jd |d xsd } |jd|d}|j-}t|t.d z }t1| }t3||}|d k7}|d k7xs |d k7xs|du}t5|||!|s|r t7|}d"}t|t.|zd#z } |dnt|t.|zd$z }!|dnt|t.|zd%z }"t9||||| |!|"S)&Nz URL too longc3bK|]'}|jxr|j )ywNisascii isprintable.0chars r zurlparse..s* E4<<> 4$"2"2"44 4 E-/c3dK|](}|js|jr%|*ywr6r7r:s rr=zurlparse..s#VTDLLN4CSCSCUDV 000z.Invalid non-printable ASCII character in URL, z at position .rr rrr usernamepasswordr raw_pathr*r r rrzURL component 'z ' too longc3bK|]'}|jxr|j )ywr6r7r:s rr=zurlparse..s*O4<<><$*:*:*<&<<Or>c3dK|](}|js|jr%|*ywr6r7r:s rr=zurlparse..s(!dllnTEUEUEWDr@z-Invalid non-printable ASCII character in URL z component, zInvalid URL component ''rrr safe) has_scheme has_authorityz`{}%|^\"z:/[]@z:/?[]@z:/?#[]@)lenMAX_URL_LENGTHranynextfind isinstanceintrpop partitionquoteget startswithendswithitemsCOMPONENT_REGEX fullmatch URL_REGEXmatch groupdictAUTHORITY_REGEXlower SUB_DELIMS encode_hostnormalize_port validate_pathnormalize_pathr)#urlr%r<idxerrorrr _rBrCrD seperatorr keyvalue url_matchurl_dictrrr r r authority_matchauthority_dictr parsed_schemeparsed_userinfo parsed_host parsed_portrJrK WHATWG_SAFE parsed_path parsed_queryparsed_fragments# rr$r$s  3x.
