...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

This is the documentation for a snapshot of the develop branch, built from commit 2ef9bb34b9.

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( 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.

Parameters

Name	Description
`s`	The string to set.

Exceptions

Type	Thrown On
`system_error`	`s` contains an invalid percent-encoding.

BNF

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

query-param     = key [ "=" value ]
query-params    = [ query-param ] *( "&" query-param )
