The routine to invoke when the request completes. One of the following result codes may be passed into the completion callback: - ZOK operation completed successfully - ZAUTHFAILED authentication failed

返回值

成功时返回 TRUE, 或者在失败时返回 FALSE

错误/异常

This method emits PHP error/warning when parameters count or types are wrong or operation fails.

Caution

Since version 0.3.0, this method emits ZookeeperException and it's derivatives.

范例

Example #1 Zookeeper::addAuth() example

Add auth before requesting node value.

<?php
$zookeeper 
= new Zookeeper('locahost:2181');
$path '/path/to/node';
$value 'nodevalue';
$zookeeper->set($path$value);

$zookeeper->addAuth('digest''user0:passwd0');
$r $zookeeper->get($path);
if (
$r)
  echo 
$r;
else
  echo 
'ERR';
?>

以上例程会输出:

nodevalue
