c++ - 将字符串与 regEx 通配符值进行比较

Question

因此，我需要根据 reg ex 通配符值列表检查字符串(url)，以查看是否存在匹配项。我将拦截 HTTP 请求并根据预配置值列表进行检查，如果存在匹配，则对 URL 执行某些操作。示例:

Request URL: http://www.stackoverflow.com

Wildcards: *.stackoverflow.com/
           *.stack*.com/
           www.stackoverflow.*

有没有好的 C++ 库可以做到这一点？任何好的例子都会很棒。我的伪代码看起来像:

std::string requestUrl = "http://www.stackoverflow.com";
std::vector<string> urlWildcards = ...;

BOOST_FOREACH(string wildcard, urlWildcards) {
    if (requestUrl matches wildcard) {
        // Do something
    } else {
        // Do nothing
    }
}

非常感谢。

The following code example uses regular expressions to look for exact substring matches. The search is performed by the static IsMatch method, which takes two strings as input. The first is the string to be searched, and the second is the pattern to be searched for.

#using <System.dll>

using namespace System;
using namespace System::Text::RegularExpressions;

int main()
{
    array<String^>^ sentence = 
        {
            "cow over the moon",
            "Betsy the Cow",
            "cowering in the corner",
            "no match here"
        };

    String^ matchStr = "cow";
    for (int i=0; i<sentence->Length; i++)
    {
        Console::Write( "{0,24}", sentence[i] );
        if ( Regex::IsMatch( sentence[i], matchStr,
                 RegexOptions::IgnoreCase ) )
            Console::WriteLine("  (match for '{0}' found)", matchStr);
        else
            Console::WriteLine("");
        }
        return 0;
    }
}
