Return the query as a container of parameters
Synopsis
Declared in header <boost/url/url_view_base.hpp>
params_view
params() 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.
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 )
