boost::urls::url_base::set_encoded_params

Set the query params

Synopsis

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


url_base&
set_encoded_params(std::initializer_list<param_pct_view> ps) noexcept;

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

Calls to allocate may throw. Exceptions thrown on invalid input.


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

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