regarded and expertly designed C++ library projects in the

Set the query params.
url_base& set_encoded_params( std::initializer_list< param_pct_view > ps);
This sets the query params to the elements in the list, which may contain percent-escapes and can be empty. An empty list of params is distinct from having no query. Escapes in the string are preserved, and reserved characters in the string are percent-escaped in the result.
assert( url( "http://example.com" ).set_encoded_params( { "id" , "42" } ).encoded_query() == "id=42" );
this->has_query() == true
Linear.
Strong guarantee. Calls to allocate may throw. Exceptions thrown on invalid input.
