Match Url path without query string
提问by JCoder23
I would like to match a path in a Url, but ignoring the querystring. The regex should include an optional trailing slash before the querystring.
我想匹配 Url 中的路径，但忽略查询字符串。正则表达式应该在查询字符串之前包含一个可选的尾部斜杠。
Example urls that should give a valid match:
应该给出有效匹配的示例网址：
/path/?a=123&b=123
/path?a=123&b=123
So the string '/path' should match either of the above urls.
所以字符串 '/path' 应该匹配上述任一网址。
I have tried the following regex: (/path[^?]+).*
我尝试了以下正则表达式： (/path[^?]+).*
But this will only match urls like the first example above: /path/?a=123&b=123
但这只会匹配上面第一个示例的网址： /path/?a=123&b=123
Any idea how i would go about getting it to match the second example without the trailing slash as well?
知道我将如何让它与第二个示例相匹配而没有尾部斜杠吗？
Regex is a requirement.
正则表达式是一项要求。

No need for regexp:
不需要正则表达式：
url.split("?")[0];
If you really need it, then try this:
如果你真的需要它，那么试试这个：
\/path\?*.*
EDITActually the most precise regexp should be:
编辑实际上最精确的正则表达式应该是：
^(\/path)(\/?\?{0}|\/?\?{1}.*)$
because you want to match either /pathor /path/or /path?somethingor /path/?somethingand nothing else. Note that ?means "at most one" while \?means a question mark.
因为你想匹配/pathor/path/或/path?somethingor/path/?something并且没有别的。请注意，这?意味着“最多一个”，而\?意味着一个问号。
BTW: What kind of routing library does not handle query strings?? I suggest using something else.
BTW：什么样的路由库不处理查询字符串？？我建议使用其他东西。

var re = /(\/?[^?]*?)\?.*/;
var p1 = "/path/to/something/?a=123&b=123";
var p2 = "/path/to/something/else?a=123&b=123";
var p1_matches = p1.match(re);
var p2_matches = p2.match(re);
document.write(p1_matches[1] + "<br>");
document.write(p2_matches[1] + "<br>");
