执行 Google Sheets API php Quickstart 授权时出现 Http 错误 500

Question

我一直在关注 Google Sheets API v4 以通过 PHP 在我的 Google Sheet 中执行特定任务。我遵循API quickstart 并只是复制粘贴代码并在我的代码中更改了工作表的凭据。当我运行代码时，页面未加载并出现此错误：

localhost 当前无法处理此请求。 HTTP 错误 500。

我不知道为什么它没有加载。这几行可能有问题，但我不确定：

if ($client->isAccessTokenExpired()) {
    $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
    file_put_contents($credentialsPath, json_encode($client->getAccessToken()));
}

我的代码在下面

<?php
require __DIR__ . '/vendor/autoload.php';
function getClient()
{
    $client = new Google_Client();
    $client->setApplicationName('Google Sheets API PHP Quickstart');
    $client->setScopes(Google_Service_Sheets::SPREADSHEETS_READONLY);
    $client->setAuthConfig('client_secret.json');
    $client->setAccessType('offline');
    // Load previously authorized credentials from a file.
    $credentialsPath = expandHomeDirectory('credentials.json');
    if (file_exists($credentialsPath)) {
        $accessToken = json_decode(file_get_contents($credentialsPath), true);
    } else {
        // Request authorization from the user.
        $authUrl = $client->createAuthUrl();
        printf("Open the following link in your browser:\n%s\n", $authUrl);
        print 'Enter verification code: ';
        $authCode = trim(fgets(STDIN));
        // Exchange authorization code for an access token.
        $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);
        // Store the credentials to disk.
        if (!file_exists(dirname($credentialsPath))) {
            mkdir(dirname($credentialsPath), 0700, true);
        }
        file_put_contents($credentialsPath, json_encode($accessToken));
        printf("Credentials saved to %s\n", $credentialsPath);
    }
    $client->setAccessToken($accessToken);
    // Refresh the token if it's expired.
    if ($client->isAccessTokenExpired()) {
        $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
        file_put_contents($credentialsPath, json_encode($client->getAccessToken()));
    }
    return $client;
}
/**
 * Expands the home directory alias '~' to the full path.
 * @param string $path the path to expand.
 * @return string the expanded path.
 */
function expandHomeDirectory($path)
{
    $homeDirectory = getenv('HOME');
    if (empty($homeDirectory)) {
        $homeDirectory = getenv('HOMEDRIVE') . getenv('HOMEPATH');
    }
    return str_replace('~', realpath($homeDirectory), $path);
}
// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Sheets($client);
// Prints the names and majors of students in a sample spreadsheet:
// https://docs.google.com/spreadsheets/d/1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms/edit
$spreadsheetId = '1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms';
$range = 'Class Data!A2:E';
$response = $service->spreadsheets_values->get($spreadsheetId, $range);
$values = $response->getValues();
if (empty($values)) {
    print "No data found.\n";
} else {
    print "Name, Major:\n";
    foreach ($values as $row) {
        // Print columns A and E, which correspond to indices 0 and 4.
        printf("%s, %s\n", $row[0], $row[4]);
    }
}
// [END sheets_quickstart]

我实际上不知道如何在我的本地主机中运行这个 api。

使用以下命令运行示例：

php quickstart.php / or your php file name

第一次运行示例时，它会提示您授权访问：

1. 在您的网络浏览器中浏览到提供的 URL。
   如果您尚未登录 Google 帐户，系统会提示您登录。如果您登录了多个 Google 帐户，系统会要求您选择一个帐户用于授权。

2. 点击接受按钮。

3. 复制您提供的代码，将其粘贴到命令行提示符中，然后按 Enter。
