boost::urls::url_view_base::params

Return the query as a container of parameters

Synopsis

params_view
params() const noexcept;
params_view
params(encoding_opts opt) const noexcept;

Description

This function returns a bidirectional view of key/value pairs over the query. The returned view references the same underlying character buffer; ownership is not transferred. Any percent-escapes in strings returned when iterating the view are decoded first.

params_view pv = url_view( "/sql?id=42&name=jane%2Ddoe&page+size=20" ).params();

Constant.

Throws nothing.

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

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