使用正则表达式获取不含查询字符串的网址

Question

I am looking for a way to parse URL without queryString using Regular expression.

i have url like "http://abc.com/csd?/aaa/bbb"

expected is like "http://abc.com/csd"

Anybody help me on this.

Answer 1

如果只需要查询字符串之前的所有内容：

^[^?]+

Answer 2

You could use Substring and IndexOf

var someString = "http://abc.com/csd?/aaa/bbb";
someString.Substring(0, someString.IndexOf('?') - 1);

while this does not fully comply with the requirements stated in your question, it might be an easier approach - if actual implementation does not need to be RegEx.

Answer 3

Regex r = new Regex("(^[^?]+)");
Match m = r.Match("http://example.com/csd?/aaa/bbb");
// m.Groups[0].Value is your URL
