Question

我尝试使用服务帐户在Google日历上创建条目。我真的很接近这一点，但最后一行不会奏效。当我让它运行时，我得到一个500 Internal Service Error。否则，程序运行无错误，无论值得做什么。

可以找到Calendar.php个文件内容here。我尝试调用的insert()方法从该文件的第1455行开始。

<?php

function calendarize ($title, $desc, $ev_date, $cal_id) {

    session_start();

    /************************************************
    Make an API request authenticated with a service
    account.
    ************************************************/
    set_include_path( '../google-api-php-client/src/');

    require_once 'Google/Client.php';
    require_once 'Google/Service/Calendar.php';

    // (not real keys)
    $client_id = '843319906820-jarm3f5ctbtjj9b7lp5qdcqal54p1he6.apps.googleusercontent.com';
    $service_account_name = '843319906820-jarm3f5ctbtjj7b7lp5qdcqal54p1he6@developer.gserviceaccount.com';
    $key_file_location = '../google-api-php-client/calendar-249226a7a27a.p12';

//    echo pageHeader("Service Account Access");
    if (!strlen($service_account_name) || !strlen($key_file_location))
        echo missingServiceAccountDetailsWarning();

    $client = new Google_Client();
    $client->setApplicationName("xxxx Add Google Calendar Entries");

    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()) {
        $client->getAuth()->refreshTokenWithAssertion($cred);
    }
    $_SESSION['service_token'] = $client->getAccessToken();

    // Prior to this, the code has mostly come from Google's example
    //     google-api-php-client / examples / service-account.php
    // and relates to getting the access tokens. 

    // The rest of this is about setting up the calendar entry.
    //Set the Event data
    $event = new Google_Service_Calendar_Event();
    $event->setSummary($title);
    $event->setDescription($desc);

    $start = new Google_Service_Calendar_EventDateTime();
    $start->setDate($ev_date);
    $event->setStart($start);

    $end = new Google_Service_Calendar_EventDateTime();
    $end->setDate($ev_date);     
    $event->setEnd($end);

    $calendarService = new Google_Service_Calendar($client);
    $calendarList = $calendarService->calendarList;

    $events = $calendarService->events;

    // if I leave this line, my code won't crash (but it won't do anything, either)
    //echo "here"; die(); 

    $events.insert($cal_id, $event, false);
} 

?>

Answer 1

我想出来了。由于我没有看到任何使用API v3服务帐户的完整示例，因此我将发布完整的解决方案以供参考。但是，除了实现代码之外，您还需要做一些事情：

1）您需要转到Google Developer's console并将您的帐户标记为“＆＃39;服务帐户”。这将使其与Web应用程序区分开来。重要的区别是，在添加事件之前，系统不会提示用户登录其帐户，因为该帐户将属于您的应用程序，而不是最终用户。有关详细信息，请参阅第5页上的article。

2）您需要创建公钥/私钥对。在开发人员的控制台中，单击“凭据”。在您的服务帐户下，点击“生成新的P12密钥＆＃39;”。你需要把它存放在某个地方。该文件位置成为下面代码中的$key_file_location变量字符串。

3）同样来自开发人员的控制台，您需要启用Calendar API。从您的项目左侧边缘，您将看到APIs。选择该选项并找到Calendar API。点击它，接受服务条款，并确认它现在显示在Enabled APIs下，状态为On

4）在Google日历中，您要添加活动，在设置下点击日历设置，然后点击“分享此日历”＆＃39;在顶部。根据＆＃39;与特定人员分享＆＃39;在＆＃39;人物中字段，从服务帐户凭据粘贴到电子邮件地址。将权限设置更改为“对事件进行更改＆＃39;”。不要忘记保存更改。

然后，在某处实现此代码。

评论某些内容是否令人困惑或遗漏。祝你好运！

Answer 2

以下是Google API Client 2.0的使用方法

按照Alex的答案转到Google Developer's console创建服务帐户，但在 JSON

中创建凭证

关注Google API Client Upgrade Guide，由作曲家安装，并以

的方式加入

 require_once 'vendor/autoload.php';

按照Alex的答案转到Google日历，与服务帐户ID分享日历

xxxxx@yyyy.iam.gserviceaccount.com

采取参考。以下编码和最重要的一个是日历ID应该是日历创建者的电子邮件，但不是主要的

<?php


require_once __DIR__.'/vendor/autoload.php';
   session_start();     


$client = new Google_Client();
$application_creds = __DIR__.'/secret.json';  //the Service Account generated cred in JSON
$credentials_file = file_exists($application_creds) ? $application_creds : false;
define("APP_NAME","Google Calendar API PHP");   //whatever
$client->setAuthConfig($credentials_file);
$client->setApplicationName(APP_NAME);
$client->addScope(Google_Service_Calendar::CALENDAR);
$client->addScope(Google_Service_Calendar::CALENDAR_READONLY);

//Setting Complete

//Go Google Calendar to set "Share with ..."  Created in Service Account (xxxxxxx@sustained-vine-198812.iam.gserviceaccount.com)

//Example of Use of API
$service = new Google_Service_Calendar($client);  


$calendarId = 'xxxx@gmail.com';   //NOT primary!! , but the email of calendar creator that you want to view
$optParams = array(
  'maxResults' => 10,
  'orderBy' => 'startTime',
  'singleEvents' => TRUE,
  'timeMin' => date('c'),
);
$results = $service->events->listEvents($calendarId, $optParams);

if (count($results->getItems()) == 0) {
  print "No upcoming events found.\n";
} else {
  echo "Upcoming events:";
  echo "<hr>";
  echo "<table>";
  foreach ($results->getItems() as $event) {
    $start = $event->start->dateTime;
    if (empty($start)) {
      $start = $event->start->date;
    }
    echo "<tr>";
    echo"<td>".$event->getSummary()."</td>";
    echo"<td>".$start."</td>";
    echo "</tr>";
  }
  echo "</table>";
}
