PHP Google 日历 API

Question

在项目中进行设置的初始阶段。我已在 Google 开发者页面启用它并尝试遵循快速入门指南

https://developers.google.com/calendar/quickstart/php

然而，与大多数 Google API 教程一样，此 'quickstart' 不起作用。我浏览了授权页面并获得了我在终端中输入的代码，但很长一段时间后我才收到错误

PHP Fatal error:  Uncaught RuntimeException: Unable to read from stream in [site root]/vendor/guzzlehttp/psr7/src/Stream.php

    Stack trace:

没有创建 token.json 文件，但是该目录是可写的。

怀疑Google代码有误。更改第 16 行的范围允许它正确运行。

$client->setScopes("https://www.googleapis.com/auth/calendar.readonly");

完整代码：

<?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_READONLY);
    $client->setScopes("https://www.googleapis.com/auth/calendar.readonly");

    $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(', ', $accessToken));
            }
        }
        // Save the token to a file.
        if (!file_exists(dirname($tokenPath))) {
            mkdir(dirname($tokenPath), 0700, true);
        }
        file_put_contents($tokenPath, json_encode($client->getAccessToken()));
    }
    return $client;
}


// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Calendar($client);

// Print the next 10 events on the user's calendar.
$calendarId = 'primary';
$optParams = array(
    'maxResults' => 10,
    'orderBy' => 'startTime',
    'singleEvents' => true,
    'timeMin' => date('c'),

$results = $service->events->listEvents($calendarId, $optParams);

if (empty($events)) {
    print "No upcoming events found.\n";

    foreach ($events as $event) {
        $start = $event->start->dateTime;

}
