Return the query as a container of parameters
Synopsis
Declared in header <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.
Example
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.
