php - 我可以使用我的 php 应用程序在 Google 日历中添加事件吗？

Question

是否可以在 Google 日历中添加/编辑/删除事件？因为我所做的只是阅读我的事件。我正在启用我可以找到的有关日历 API 的所有“范围”，但仍然收到有关“请求的身份验证范围不足/权限被拒绝”的错误 403。

我已经做了很多尝试来解决这个问题，而且每次我都达到了相同的点。我正在使用 OAuth 2.0 客户端 ID 凭据，还有一个问题是我应该将哪个 url 用于授权重定向 URI。

        $accessToken = json_decode(file_get_contents($tokenPath), true);

我可以通过使用与您相同的代码稍作修改来创建事件。我修改了只读范围以允许读/写访问而不是只读。这是最终结果：

<?php
require __DIR__ . '/vendor/autoload.php';
/*
if (php_sapi_name() != 'cli') {
    throw new Exception('This application must be run on the command line.');
}
*/
/**
 * Returns an authorized API client.
 * @return Google_Client the authorized client object
 */
function getClient()
{
    $client = new Google_Client();
    $client->setApplicationName('Google Calendar API PHP Quickstart');
    $client->setScopes(Google_Service_Calendar::CALENDAR);
    $client->setAuthConfig('credentials.json');
    $client->setAccessType('offline');
    $client->setPrompt('select_account consent');

    // Load previously authorized token from a file, if it exists.
    // The file token.json stores the user's access and refresh tokens, and is
    // created automatically when the authorization flow completes for the first
    // time.
    $tokenPath = 'token.json';
    if (file_exists($tokenPath))
    {
        $accessToken = json_decode(file_get_contents($tokenPath) , true);
        $client->setAccessToken($accessToken);
    }

    // If there is no previous token or it's expired.
    if ($client->isAccessTokenExpired())
    {
        // Refresh the token if possible, else fetch a new one.
        if ($client->getRefreshToken())
        {
            $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
        }
        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);
            $client->setAccessToken($accessToken);

            // Check to see if there was an error.
            if (array_key_exists('error', $accessToken))
            {
                throw new Exception(join(', ', $accessToken));
            }
        }
        // Save the token to a file.

        {
            mkdir(dirname($tokenPath) , 0700, true);
        }
        file_put_contents($tokenPath, json_encode($client->getAccessToken()));
    }
    return $client;
