Function url:: set_params

Set the query params

            url&
set_params(std::initializer_list ps);

This sets the query params to the list of param_view, which can be empty.

An empty list of params is distinct from having no params.

Reserved characters in the string are percent-escaped in the result.


assert( url( "http://example.com" ).set_params( {"id", "42"} ).query() == "id=42" );


this->has_query() == true

Strong guarantee. Calls to allocate may throw.

Linear.


query           = *( pchar / "/" / "?" )

query-param     = key [ "=" value ]
query-params    = [ query-param ] *( "&" query-param )
