好吧,我想我会去做一个混合的自定义函数集:
编码:使用encodeURIComponent(),然后将斜杠重新插入。
解码:解码找到的任何%十六进制值。
这是一个更完整的变体,我最终使用(它也正确处理Unicode):
函数quoteUrl(url,safe){
if(typeof(safe)!=='string'){
safe ='/'; //默认情况下不要退出斜杠
}
url = encodeURIComponent(url);
//取消对安全列表中的字符
toUnencode = [];
for(var i = safe.length - 1; i> = 0; --i){
var encoded = encodeURIComponent(safe [i]);
if(encoded!== safe.charAt(i)){//如果没有转义,则忽略安全字符
toUnencode.push(encoded);
}
}
url = url.replace(new RegExp(toUnencode.join('|'),'ig'),decodeURIComponent);
return url;
}
var unquoteUrl = decodeURIComponent; //使别名具有对称函数名称
请注意,如果不需要安全字符在Python中默认编码('/'
)时,您只需使用内置的 encodeURIComponent()
和 decodeURIComponent()
函数直接。
另外,如果有Unicode字符(即具有codepoint> = 128的字符),然后为了保持与JavaScript的 encodeURIComponent()
的兼容性,Python quote_url()
将必须:
$ b
def quote_url(url,safe):
URL编码一个字符串ASCII)或unicode);
使用事实上的UTF-8编码来处理给定字符串中的Unicode代码点
return urllib.quote(unicode(url)).encode(' utf-8'),安全)
和 unquote_url()
将是:
def unquote_url(url):
解码使用quote_url编码的网址。
返回一个unicode实例。
return urllib.unquote(url).decode('utf-8')
Are there any equivalent Javascript functions for Python's urllib.quote()
and urllib.unquote()
?
The closest I've come across are escape()
, encodeURI()
, and encodeURIComponent()
(and their corresponding un-encoding functions), but they don't encode/decode the same set of special characters as far as I can tell.
Thanks,
Cameron
OK, I think I'm going to go with a hybrid custom set of functions:
Encode: Use encodeURIComponent(), then put slashes back in.
Decode: Decode any %hex values found.
Here's a more complete variant of what I ended up using (it handles Unicode properly, too):
function quoteUrl(url, safe) {
if (typeof(safe) !== 'string') {
safe = '/'; // Don't escape slashes by default
}
url = encodeURIComponent(url);
// Unescape characters that were in the safe list
toUnencode = [ ];
for (var i = safe.length - 1; i >= 0; --i) {
var encoded = encodeURIComponent(safe[i]);
if (encoded !== safe.charAt(i)) { // Ignore safe char if it wasn't escaped
toUnencode.push(encoded);
}
}
url = url.replace(new RegExp(toUnencode.join('|'), 'ig'), decodeURIComponent);
return url;
}
var unquoteUrl = decodeURIComponent; // Make alias to have symmetric function names
Note that if you don't need "safe" characters when encoding ('/'
by default in Python), then you can just use the built-in encodeURIComponent()
and decodeURIComponent()
functions directly.
Also, if there are Unicode characters (i.e. characters with codepoint >= 128) in the string, then to maintain compatibility with JavaScript's encodeURIComponent()
, the Python quote_url()
would have to be:
def quote_url(url, safe):
"""URL-encodes a string (either str (i.e. ASCII) or unicode);
uses de-facto UTF-8 encoding to handle Unicode codepoints in given string.
"""
return urllib.quote(unicode(url).encode('utf-8'), safe)
And unquote_url()
would be:
def unquote_url(url):
"""Decodes a URL that was encoded using quote_url.
Returns a unicode instance.
"""
return urllib.unquote(url).decode('utf-8')
