static_url_base::params (1 of 4 overloads)

(Inherited from url_base)

Return the query as a container of parameters.

Synopsis
params_ref
params();
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
[link url.ref.boost__urls__url_base.params_ref `params_ref`] pv = [link url.ref.boost__urls__url_base.url `url`]( "/sql?id=42&name=jane%2Ddoe&page+size=20" ).params();
Complexity

Constant.

Exception Safety

Throws nothing.

BNF
[link url.ref.boost__urls__static_url_base.query `query`]           = *( pchar / "/" / "?" )

[link url.ref.boost__urls__static_url_base.query `query`]-param     = key [ "=" value ]
[link url.ref.boost__urls__static_url_base.query `query`]-[link url.ref.boost__urls__static_url_base.params `params`]    = [ [link url.ref.boost__urls__static_url_base.query `query`]-param ] *( "&" [link url.ref.boost__urls__static_url_base.query `query`]-param )
