#includeIn this example, we create a KURL object from the URL string, extract the protocol component of the URL using the protocol function, and then call the protocolIsInHTTPFamily function to check if the protocol is in the HTTP family. The KURL library is part of the KDE frameworks, a collection of libraries that provide a wide range of functionality for developing desktop applications on Linux, Windows, and macOS.... bool isHTTPProtocol(const std::string& url) { KURL kurl(url); std::string protocol = kurl.protocol(); return protocolIsInHTTPFamily(protocol); }
