params

Return the query as a container of parameters

Synopsis

params_ref
params(encoding_opts opt) noexcept;

Declared in file <include/boost/url/url_base.hpp> on line 2136

Defined in file <src/url_base.cpp> on line 1424

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.

BNF
