(Inherited from url_base
)
Set the query params.
url_base& set_params( std::initializer_list< param_view > 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( [link url.ref.boost__urls__url_base.url `url`]( "http://example.com" ).[link url.ref.boost__urls__static_url.set_params `set_params`]( { "id" , "42" } ).[link url.ref.boost__urls__static_url.query `query`]() == "id=42" );
