Question

我已下载适用于PHP的Google API库客户端，现在正尝试与OAuth建立连接。但是，使用 service-account.php 中的以下代码：

$client_id = 'CLIENT-ID-GENERATED-FROM-GOOGLE-DEVELOPERS-CONSOLE.apps.googleusercontent.com';

    array('https://www.googleapis.com/auth/analytics.readonly'),
    $key
);
$client->setAssertionCredentials($cred);
if($client->getAuth()->isAccessTokenExpired()) {
  $client->getAuth()->refreshTokenWithAssertion($cred);
}
$_SESSION['service_token'] = $client->getAccessToken();

/************************************************
  We're just going to make the same call as in the
  simple query as an example.
 ************************************************/
$optParams = array('filter' => 'free-ebooks');
$results = $service->volumes->listVolumes('Henry David Thoreau', $optParams);
echo "<h3>Results Of Call:</h3>";
foreach ($results as $item) {
  echo $item['volumeInfo']['title'], "<br /> \n";
}

echo pageFooter(__FILE__);

我收到此错误：

致命错误：未捕获的异常＆＃39; Google_Auth_Exception＆＃39;有消息＆＃39;错误刷新OAuth2令牌，消息：＆＃39; {＆＃34;错误＆＃34; ：＆＃34; invalid_grant＆＃34; }＆＃39;＆＃39;在/home/texterx1/public_html/google-api-php-client-master/src/Google/Auth/OAuth2.php:327堆栈跟踪：＃0 / home / texterx1 / public_html / google-api-php-client-master /src/Google/Auth/OAuth2.php(289）：Google_Auth_OAuth2-＆gt; refreshTokenRequest（数组）＃1 /home/texterx1/public_html/google-api-php-client-master/examples/service-account.php(75 ）：：第327行/home/texterx1/public_html/google-api-php-client-master/src/Google/Auth/OAuth2.php中引用的Google_Auth_OAuth2-＆gt; refreshTokenWithAssertion（Object（Google_Auth_AssertionCredentials））＃2 {main} < / p>

我做错了什么？

怀疑

我怀疑的是，我已将错误的值复制/粘贴到$client_id，$service_account_name和$key_file_location。我从字段服务帐户客户端ID $client_id获得了$service_account_name，我从同意屏幕＆gt;获取了$key_file_location当我点击生成服务帐户下面的新密钥时，下载到我电脑的.p12文件上的文件名中的产品名称和{{1}}。我首先在我的计算机上打开.p12文件，然后按照指南进行操作，例如导入证书（不确定我是否应该这样做）。
