如何在Google Insights中通过Google授权下载cvs文件-必须使用zend类而不是其他php方式（zend_gbase等。）

$email

$passwd

// setup the autoloader first or require used classes
// using the example code in the example to get auth tokens
try {
    $client = Zend_Gdata_ClientLogin::getHttpClient($email, $passwd, \'xapi\', $httpClient);
} 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\";
}

// extract authentication tokens from response body
$ck_count = preg_match_all(\'/^(.+)=(.+)$/m\', $client->getLastResponse()->getBody(), $cookies);

// build a new http client
$auth = new Zend_Http_Client(\'http://www.google.com/trends/viz?q=facebook&graph=all_csv&sa=N\');

for ($i = 0; $i < $ck_count; $i++) {
    // authenticate it using the provided tokens as cookies
    $auth->setCookie($cookies[1][$i], $cookies[2][$i]);
}
// make the request and dump cvs data
Zend_Debug::dump($auth->request()->getBody());
