示例1: __construct

 /**
  * Construct a new write guard for a request. Only one write guard may be
  * active at a time. You must explicitly call @{method:dispose} when you are
  * done with a write guard:
  *
  *    $guard = new AphrontWriteGuard($callback);
  *    // ...
  *    $guard->dispose();
  *
  * Normally, you do not need to manage guards yourself -- the Aphront stack
  * handles it for you.
  *
  * This class accepts a callback, which will be invoked when a write is
  * attempted. The callback should validate the presence of a CSRF token in
  * the request, or abort the request (e.g., by throwing an exception) if a
  * valid token isn't present.
  *
  * @param   callable CSRF callback.
  * @return  this
  * @task    manage
  */
