Set the port

set_port(

Declared in file <boost/url/url.hpp> at line 458

This port is set to the string, which must contain only digits or be empty. An empty port string is distinct from having no port.


assert( url( "http://www.example.com" ).set_port( "8080" ).authority().buffer() == "www.example.com:8080" );


this->has_port() == true && this->port_number() == n && this->port() == std::to_string(n)
