我可以使用我的php应用程序在谷歌日历添加事件吗?

Question

是否可以在谷歌日历中添加/编辑/删除事件?因为我所完成的只是阅读我的事件。我启用了所有的作用域我可以找到关于日历API，但我仍然得到一个错误403关于"请求没有足够的身份验证范围/PERMISSION denied"。

我已经做了很多尝试来解决这个问题，每次我都遇到同样的问题。我正在使用OAuth 2.0客户端id凭证，我还有一个问题是我应该为授权重定向uri使用哪个url。

我能够通过使用相同的代码进行小编辑来创建事件。我修改了只读作用域，允许读/写访问，而不是只读。这是最终的结果:

<?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%sn", $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(', ', $accessToken));
}
}
// Save the token to a file.
if (!file_exists(dirname($tokenPath)))
{
mkdir(dirname($tokenPath) , 0700, true);

file_put_contents($tokenPath, json_encode($client->getAccessToken()));

return $client;
