[#0F3A8CA5A257D8EDB9BCF17110DE440D3C94EAEC]
A view representing query parameters in a URL
class params_view : public params_base;
Objects of this type are used to interpret the query parameters as a bidirectional view of key/value pairs.
The view does not retain ownership of the elements and instead references the original character buffer. The caller is responsible for ensuring that the lifetime of the buffer extends until it is no longer referenced.
url_view u( "?first=John&last=Doe" );
params_view p = u.params();
Percent escapes in strings returned when dereferencing iterators are automatically decoded.
Changes to the underlying character buffer can invalidate iterators which reference it.
