PHP google-api-php-client获取用户文件结构

Question

我试图建立一个内容管理系统，使用谷歌驱动器帐户作为存储和显示其内容，文件/文件夹，用户应该能够通过我的角度FrontEnd管理这些文件。我是google-api的新手，我想试一试，但我被卡住了。

我正在使用这个库让它在我本地的xampp上用PHP运行。

Git Google PHP API

我尝试在用户文件的.php测试文件中获得响应，如下所示：

/*************************************************
 * Ensure you've downloaded your oauth credentials
 ************************************************/
if (!$oauth_credentials = getOAuthCredentialsFile())
{
    echo missingOAuth2CredentialsWarning();
    return;
}

/************************************************
 * The redirect URI is to the current page, e.g:
 * http://localhost:8080/simple-file-upload.php
 ************************************************/
$redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];

$client = new Google_Client();
$client->setAuthConfig($oauth_credentials);
$client->setRedirectUri($redirect_uri);
$client->addScope(Google_Service_Drive::DRIVE);
$service = new Google_Service_Drive($client);


$pageToken = null;
do {
    $response = $service->files->listFiles();

    foreach ($response->files as $file) {
        printf("Found file: %s (%s)\n", $file->name, $file->id);
    }
} while ($pageToken != null);

但这会抛出致命错误:未捕获Google_Service_Exception：{ "error"：{ "errors"：[{ "domain"："usageLimits"，"reason"："dailyLimitExceededUnreg"，"message"：“超过每日未授权使用限制。继续使用需要注册。”，

我让git存储库的示例正常工作。但是我没有找到一个有用的例子来查询用户的文件结构。

我发现了我在测试应用程序中缺少的东西:像这样设置访问令牌->

   if (isset($_GET['code']))
{
    $token = $client->fetchAccessTokenWithAuthCode($_GET['code']);
    $client->setAccessToken($token); //really needed? we also set it when the session is not empty 

    // store in the session also
    $_SESSION['upload_token'] = $token;

    // redirect back to the example
    header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}

// set the access token as part of the client
if (!empty($_SESSION['upload_token']))
{
    $client->setAccessToken($_SESSION['upload_token']);
    if ($client->isAccessTokenExpired())
    {
        unset($_SESSION['upload_token']);
    }
}
else
{
    $authUrl = $client->createAuthUrl();
}

使用客户端创建服务，如->

$service = new Google_Service_Drive($client);

最后，重要的一点是:只有在登录的情况下才能访问它

/************************************************
 * If we're signed in then lets try to do something
 ************************************************/
if ( $client->getAccessToken())
{
    $response = $service->files->listFiles();

    foreach ($response->files as $file)
    {
        echo "<div>" . $file->name . " - " . $file->id . "</div><br>";
    }
}
