boost::urls::url_base::set_params

Set the query params

Declared in header <boost/url/url_base.hpp>

url_base&
set_params(
    std::initializer_list<param_view> ps,
    encoding_opts opts = = {}) noexcept;

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

Calls to allocate may throw.

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

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