Parse (absolute and relative) URLs. urlparse module is based upon the following RFC specifications. RFC 3986 (STD66): "Uniform Resource Identifiers" by T. Berners-Lee, R. Fielding and L. Masinter, January 2005. RFC 2732 : "Format for Literal IPv6 Addresses in URL's by R.Hinden, B.Carpenter and L.Masinter, December 1999. RFC 2396: "Uniform Resource Identifiers (URI)": Generic Syntax by T. Berners-Lee, R. Fielding, and L. Masinter, August 1998. RFC 2368: "The mailto URL scheme", by P.Hoffman , L Masinter, J. Zawinski, July 1998. RFC 1808: "Relative Uniform Resource Locators", by R. Fielding, UC Irvine, June 1995. RFC 1738: "Uniform Resource Locators (URL)" by T. Berners-Lee, L. Masinter, M. McCahill, December 1994 RFC 3986 is considered the current standard and any future changes to urlparse module should conform with it. The urlparse module is currently not entirely compliant with this RFC due to defacto scenarios for parsing, and for backward compatibility purposes, some parsing quirks from older RFCs are retained. The testcases in test_urlparse.py provides a good indicator of parsing behavior. )absolute_importdivisionunicode_literals)byteschrdictintrangestr)raise_with_tracebackNurlparse urlunparseurljoin urldefragurlsplit urlunsplit urlencodeparse_qs parse_qslquote quote_plusquote_from_bytesunquote unquote_plusunquote_to_bytesftphttpgophernntpimapwaisfilehttpsshttpmmsprosperortsprtspusftpsvnzsvn+sshtelnetsnewsrsyncnfsgitzgit+sshhdlsipsipstelmailtonewszAabcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789+-.cCstjtjdS)z,Clear the parse cache and the quoters cache.N) _parse_cacheclear _safe_quotersr:r:?/tmp/pip-build-6m2fasei/future/future/backports/urllib/parse.py clear_cacheNsr<asciistrictcCs|S)Nr:)objr:r:r;_noop]sr@cCs |j||S)N)encode)r?encodingerrorsr:r:r;_encode_result`srDcstfdd|DS)Nc3s"|]}|r|jndVqdS)r(N)decode).0x)rBrCr:r; fsz_decode_args..)tuple)argsrBrCr:)rBrCr; _decode_argsdsrKcGsZt|dt}x.|ddD]}|rt|t|krtdqW|rL|tfSt|tfS)Nrz$Cannot mix str and non-str arguments) isinstancer TypeErrorr@rKrD)rJ str_inputargr:r:r; _coerce_argshs  rQc@seZdZdZfZdddZdS)_ResultMixinStrz>Standard approach to encoding parsed results from str to bytesr=r>cs|jfdd|DS)Nc3s|]}|jVqdS)N)rA)rFrG)rBrCr:r;rH~sz)_ResultMixinStr.encode..)_encoded_counterpart)selfrBrCr:)rBrCr;rA}sz_ResultMixinStr.encodeN)r=r>)__name__ __module__ __qualname____doc__ __slots__rAr:r:r:r;rRysrRc@seZdZdZfZdddZdS)_ResultMixinBytesz>Standard approach to decoding parsed results from bytes to strr=r>cs|jfdd|DS)Nc3s|]}|jVqdS)N)rE)rFrG)rBrCr:r;rHsz+_ResultMixinBytes.decode..)_decoded_counterpart)rTrBrCr:)rBrCr;rEsz_ResultMixinBytes.decodeN)r=r>)rUrVrWrXrYrEr:r:r:r;rZsrZc@sDeZdZdZfZeddZeddZeddZedd Z d S) _NetlocResultMixinBasezHShared methods for the parsed result objects containing a netloc elementcCs |jdS)Nr) _userinfo)rTr:r:r;usernamesz_NetlocResultMixinBase.usernamecCs |jdS)NrL)r])rTr:r:r;passwordsz_NetlocResultMixinBase.passwordcCs(|jd}|sd}n|dk r$|j}|S)Nr) _hostinfolower)rThostnamer:r:r;rbs  z_NetlocResultMixinBase.hostnamecCs<|jd}|dk r8t|d}d|ko.dkns8dS|S)NrL ri)r`r)rTportr:r:r;rds   z_NetlocResultMixinBase.portN) rUrVrWrXrYpropertyr^r_rbrdr:r:r:r;r\s    r\c@s(eZdZfZeddZeddZdS)_NetlocResultMixinStrcCsD|j}|jd\}}}|r4|jd\}}}|s:///;?# Return a 6-tuple: (scheme, netloc, path, params, query, fragment).

RFC 2396 Uniform Resource Identifiers (URI): Generic Syntax lists the following reserved characters. reserved = ";" | "/" | "?" | ":" | "@" | "&" | "=" | "+" | "$" | "," Each of these characters is reserved in some component of a URL, but not necessarily in all of them. By default, the quote function is intended for quoting the path section of a URL. Thus, it will not encode '/'. This character is reserved, but in typical usage the quote function is being called on a path where the existing slash characters are used as reserved characters. string and safe may be either str or bytes objects. encoding must not be specified if string is a str. The optional encoding and errors parameters specify how to deal with non-ASCII characters, as accepted by the str.encode method. By default, encoding='utf-8' (characters are encoded with UTF-8), and errors='strict' (unsupported characters raise a UnicodeEncodeError).
