public static HashTable<string,string> parse_params (string uri, size_t length = -1, string separators = "&;", UriParamsFlags flags = 0) throws UriError
Many URI schemes include one or more attribute/value pairs as part of the URI value.
This method can be used to parse them into a hash table. When an attribute has multiple occurrences, the last value is the final returned value. If you need to handle repeated attributes differently, use UriParamsIter.
params string is assumed to still be `%`-encoded, but the returned values will be fully decoded. (Thus it is possible that the
returned values may contain `=` or
separators, if the value was encoded in the input.) Invalid `%`-encoding is treated as with the
g_uri_flags_parse_relaxed rules for parse.
params is the path or query string from a Uri that was parsed
without g_uri_flags_parse_relaxed and g_uri_flags_encoded, then you already
know that it does not contain any invalid encoding.)
g_uri_params_www_form is handled as documented for UriParamsIter.
If g_uri_params_case_insensitive is passed to
flags, attributes will be compared
case-insensitively, so a params string `attr=123&Attr=456` will only return a single attribute–value pair, `Attr=456`. Case will be
preserved in the returned attributes.
params cannot be parsed (for example, it contains two
separators characters in a row), then
throws is set and null is returned.
the length of
the separator byte character set between parameters. (usually `&`, but sometimes `;` or both `&;`). Note that this function works on bytes not characters, so it can't be used to delimit UTF-8 strings for anything but ASCII characters. You may pass an empty set, in which case no splitting will occur.

A hash table of attribute/value pairs, with both names and values fully-decoded; or null on error.
