Set the query params.

Synopsis
url&
set_params(
    std::initializer_list< param_view > ps);
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( url( "http://example.com" ).set_params( { "id" , "42" } ).query() == "id=42" );
Postconditions
this->has_query() == true
Exception Safety

Strong guarantee. Calls to allocate may throw.

Complexity

Linear.
