使用php zend重置gmail密码

我正在努力使用php重置gmail密码，我已经遵循了这一点。运行此代码时抛出PHP致命错误：未捕获异常“Zend_Gdata_App_HttpException”，消息为“预期响应代码200，获得400” /usr/share/php/Zend/Gdata/App.php:717中的请求URI'无效

我的代码：

 <?php

//Change this for your domain
$domain = 'http://www.gmail.com/';
$email = 'mymail@gmail.com';
$passwd = 'myoldpasswd';
$user = 'mymail@gmail.com';
$newuserpassword = 'mynewpasswd';

//Connect as admin to Google Appss
require_once 'Zend/Loader.php';
Zend_Loader::loadClass('Zend_Http_Client');
Zend_Loader::loadClass('Zend_Gdata');
Zend_Loader::loadClass('Zend_Gdata_ClientLogin');
Zend_Loader::loadClass('Zend_Gdata_Gapps');
try {
  $client = Zend_Gdata_ClientLogin::getHttpClient($email, $passwd, Zend_Gdata_Gapps::AUTH_SERVICE_NAME);
} catch (Zend_Gdata_App_CaptchaRequiredException $cre) {
    echo 'URL of CAPTCHA image: ' . $cre->getCaptchaUrl() . "\n";
    echo 'Token ID: ' . $cre->getCaptchaToken() . "\n";
} catch (Zend_Gdata_App_AuthException $ae) {
   echo 'Problem authenticating: ' . $ae->exception() . "\n";
}
$gdata = new Zend_Gdata_Gapps($client, $domain);

//Now change the user's password
$updateUser = $gdata->retrieveUser($user);
$updateUser->login->password = $newuserpassword;
$updateUser = $updateUser->save();
$user->login->changePasswordAtNextLogin = true;

?>
