经过数小时的阅读Google API文档和搜索网络，我设法编写了一个简单的PHP函数，将事件插入我的Google日历（如果有人想要代码，请询问）。
但是，我想做的下一件事是删除Google日历的全部内容。 最初我以为我会通过读取所有事件然后删除每个事件来做到这一点，但根据 Google 的说法，我可以在单个命令中做到这一点：
$service->calendars->clear（$cal_id）;
但是，由于Google API文档仅涵盖实际命令，并且没有显示任何需要在此之前的代码，因此我使用了在事件插入脚本中起作用的授权代码，但是我无法让它用于清除数据，并且出现错误：
注意：未定义的变量：索引中的服务.php在第 68 行
我的整个代码如下：
<?php
//
// example code taken from:
// https://developers.google.com/google-apps/calendar/v3/reference/calendars/clear
//
//
calendclear('xxxxxxxxxxx@googlemail.com');
//---------------------------------------------------//
// funtion to delete all events from Google calendar //
//---------------------------------------------------//
function calendclear ($cal_id) {
session_start();
require_once '../google-api-php-client-master/autoload.php';
//Google credentials
$client_id = 'xxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com';
$service_account_name = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxx@developer.gserviceaccount.com';
$key_file_location = '../google-api-php-client-master/API Project-xxxxxxxxxxxx.p12';
if (!strlen($service_account_name) || !strlen($key_file_location))
echo missingServiceAccountDetailsWarning();
$client = new Google_Client();
$client->setApplicationName("Whatever the name of your app is");
if (isset($_SESSION['service_token'])) {
$client->setAccessToken($_SESSION['service_token']);
}
$key = file_get_contents($key_file_location);
$cred = new Google_Auth_AssertionCredentials(
$service_account_name,
array('https://www.googleapis.com/auth/calendar'),
$key
);
$client->setAssertionCredentials($cred);
if($client->getAuth()->isAccessTokenExpired()) {
try {
$client->getAuth()->refreshTokenWithAssertion($cred);
} catch (Exception $e) {
var_dump($e->getMessage());
}
}
$_SESSION['service_token'] = $client->getAccessToken();
$calendarService = new Google_Service_Calendar($client);
$calendarList = $calendarService->calendarList;
//delete all calendar data
try {
$service->calendars->clear($cal_id);
} catch (Exception $e) {
var_dump($e->getMessage());
}
echo 'Calendar Successfully Cleared';
}
?>
经过多次试验和错误，我找到了一种使用 API v3 清除 Google 日历的方法。
我无法获得明确的命令来工作，所以这样做我不得不：1. 读取日历中的所有事件2. 删除每个
首先，确保您的Google日历设置正确，以允许任何这些东西工作 - 答案中有4个简单的步骤 使用服务帐户插入Google日历条目
接下来，这是我使用的代码 - 请注意，最后 2 个对 xxxxxxxxxxxx@googlemail.com 引用是日历所有者电子邮件地址 - 删除不适用于"主要"或 $service_account_name。
如果你正在玩这些东西，我希望这有所帮助，因为我生命的最后两天我试图解决这个问题并没有完全浪费:)
