...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

static_url_base::params (3 of 4 overloads)

(Inherited from url_base)

Return the query as a container of parameters.

Synopsis

params_ref
params(
    encoding_opts opt);

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.

Parameters

Name	Description
`opt`	The options for decoding. If this parameter is omitted, the `space_as_plus` is used.

BNF

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

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