boost::urls::url_base::params

Synopsis

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

params_ref
params(encoding_opts opt) 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. The container is modifiable; changes to the container are reflected in the underlying URL.

encoding_opts opt;
opt.space_as_plus = true;
params_ref pv = url( "/sql?id=42&name=jane+doe&page+size=20" ).params(opt);

Complexity

Constant.

Exception Safety

Throws nothing.

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

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