params

Return the query as a container of parameters

Synopsis


                params_view
params() noexcept;

Declared in file <src/url_view_base.cpp> at line 542

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.

Example


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

Complexity

Constant.

Exception Safety

Throws nothing.

BNF


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

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