static_url_base::set_port (2 of 2 overloads)

(Inherited from url_base)

Set the port.

url_base&
set_port(
    string_view s);

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)
