Set the query

Synopsis

Declared in header </boost/url/url_base.hpp#L2028[boost/url/url_base.hpp,window=blank_]>

url_base&
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( url( "http://example.com" ).set_encoded_query( "id=42" ).encoded_query() == "id=42" );

Postconditions

this->has_query() == true && this->query() == decode_view( s );

Exception Safety

Strong guarantee. Calls to allocate may throw. Exceptions thrown on invalid input.

BNF

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