Decodes percent-encoded codes in a URI path and converts "+"
signs in the query component to spaces and returns the decoded string in UTF-8 encoding.
uri | a URI request string to decode |
The URI string is divided into three parts:
"?"
or "#"
character"?"
character terminating the path and up to a possible "#"
character"#"
characterFor all parts, any percent-encoded codes (RFC 3986 2.1) are decoded to the corresponinding character. The path component is identified and distinguished by a "?"
or a "#"
character. The path component is subjected to standard percent encoding. The query component is any part of the URI string following a "?"
character up to the end of the URI string or until a "#"
characer is found. The query component is subjected to special decoding for AJAX compatibility; "+"
characters are decoded to ASCII space (therefore any "+"
charaters in the query component of the URI must be encoded with percent encoding, such is the case with Qore::encode_uri_request() for example). The fragment component is identified as any text following a "#"
character, and this is decoded with the same rules as in the path component.
"+"
in the query component of the URI string.nothing Qore::decode_url | ( | ) |
This function variant does nothing at all; it is only included for backwards-compatibility with qore prior to version 0.8.0 for functions that would ignore type errors in arguments.
Decodes percent numeric codes in a URL string and returns the decoded string in UTF-8 encoding.
url | a URL string with percent-encodings to decode |
Encodes URI requests by substituting special characters in the path with percent-encoded equivalents and substituting spaces with "+"
and "+"
with the percent-encoded equivalent in the URI query component.
url | a URL string to encode |
The URI string is divided into three parts:
"?"
or "#"
character"?"
character terminating the path and up to a possible "#"
character"#"
characterFor all parts, any non-ASCII characters and the "%"
character are subjected to percent encoding (RFC 3986 2.1). The path component is identified and distinguished by a "?"
or a "#"
character. Any spaces in the path component are also subjected to percent encoding. The query component is any part of the URI string following a "?"
character up to the end of the URI string or until a "#"
characer is found. Spaces in the query component are encoded with "+"
for compatibility with AJAX libraries, and "+"
signs are subjected to percent encoding. The fragment component is identified as any text following a "#"
character, and this is encoded with the same rules as in the path component.
"+"
in the query component of the URI stringEncodes URLs by substituting '%'
characters with '%25'
, spaces ('
') with '%20'
, and non-ascii characters by percent-encoded representations.
url | a URL string to encode |
encode_all | if True, then in addition to '%' , spaces (' '), and non-ascii characters the following reserved characters (according to RFC 3986 are also encoded: '!' , '*' , '\'' , ' (', ' )', ' ;', ' :', '@' , '&' , '=' , '+' , '$' , ' ,', '/' , ' ?', '#' , ' [', ' ]' |
