如何使用 PHP 创建 Google 日历的列表视图

Question

我需要将 Google 日历中的事件列表放在网页上。我需要的列表可以在 Google 日历本身中看到，它是事件列表（议程样式），内容来自多个不同颜色的日历。 Google 日历也允许在 iframe 中包含此列表，但问题是，要查看这些列表，用户必须登录，否则我需要制作日历 public，但我做不到做。

以前有私人日历 url，但现在只有 iCal 提要私人可用。

所以我试图找到一个 PHP 脚本来创建这样一个列表。令人惊讶的是，我没有找到太多。大多数页面依赖于 public 日历，或者只是关于如何连接的非常基本的示例，例如 Google 的 php 示例 https://developers.google.com/google-apps/calendar/quickstart/php#step_3_set_up_the_sample 我设法开始工作，但这与我需要的相去甚远。我需要一些可以格式化的 html 输出，以及来自 3 个不同日历的数据。

要做到这一点让我有点头疼，但也许有人以前做过类似的事情，在其他地方见过吗？或者能够摆脱他们的袖子？或者有更好的建议？

我做的另一个尝试是使用 phantomjs 登录日历并截屏，但我不能运行在我的网络服务器上。

Answer 1

我设法用下面的代码模仿了议程视图。

我遇到了一些问题，即全天活动的结束日期是第二天，非全天活动返回日期时间与全天的唯一日期。

我认为代码过于复杂，这是我在缓慢的迭代步骤中找到解决方案...

这里有一些代码，如果 GET phone 号码位于 google 事件字段中的某处，有 5 种不同的 phone 数字格式之一，您将需要与日历共享的服务帐户以及创建服务帐户时获得的我的 Project.json 文件需要放入服务器上的工作文件夹（与 .

相同的文件夹）

<?php

//error_reporting(E_ALL);
//ini_set("display_errors", 1);

$credentialJson= __DIR__ . '/My Project-somehexidecimal.json'; //name of your My Project .json file
$calendarId='youremail'; //your google calendar id
$phone= $_GET['phone'];

$display = preg_replace('/^(\d{3})(\d{3})(\d{4})$/', '--', $phone);
$display1 = preg_replace('/^(\d{3})(\d{3})(\d{4})$/', '() -', $phone);
$display2 = preg_replace('/^(\d{3})(\d{3})(\d{4})$/', '', $phone);
$display3 = preg_replace('/^(\d{3})(\d{3})(\d{4})$/', '  ', $phone);
$display4 = preg_replace('/^(\d{3})(\d{3})(\d{4})$/', '()-', $phone);

$client->setAuthConfig($credentialJson);
$client->addScope('https://www.googleapis.com/auth/calendar');

$service = new Google_Service_Calendar($client);

$params = array(

$params1 = array(

$params4 = array(
