url::set_params

Set the query params.

Synopsis
url&
set_params(
    std::initializer_list< param_view > s);
Description

This sets the query params to the list of param_view, which can be empty. An empty list of params is distinct from having no params. Reserved characters in the string are percent-escaped in the result.

Example
assert( [link url.ref.boost__urls__url.url `url`]( "http://example.com" ).[link url.ref.boost__urls__url.set_params `set_params`]( { "id" , "42" } ).[link url.ref.boost__urls__url.query `query`]() == "id=42" );
Postconditions
this->[link url.ref.boost__urls__url.has_query `has_query`]() == true
