url::set_encoded_query

Set the query.

Synopsis
url&
set_encoded_query(
    pct_string_view s);
Description

This sets the query to the string, which may contain percent-escapes and can be empty. An empty query is distinct from having no query. Escapes in the string are preserved, and 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_encoded_query `set_encoded_query`]( "id=42" ).[link url.ref.boost__urls__url.encoded_query `encoded_query`]() == "id=42" );
Postconditions
this->[link url.ref.boost__urls__url.has_query `has_query`]() == true && this->[link url.ref.boost__urls__url.query `query`]() == decode_view( s );
Exception Safety
