假设有一款应用可以帮助用户查找最佳徒步路线。通过将 远足计划作为日历活动,那么用户会获得很多帮助 自动整理照片Google 日历能帮助他们 提醒他们要做的事,以便他们可以放心无忧。此外,多亏了 无缝集成了 Google 产品,Google 即时会向他们发出 Google 地图会准时将其定向到会面地点。

本文介绍了如何创建日历活动并将其添加到用户的 日历。

添加活动

要创建事件,请调用 events.insert() 方法提供 至少这些参数:

  • calendarId 是日历标识符,可以是电子邮件地址 日历的名称或特殊关键字 'primary',将使用登录用户的主日历。如果 您不知道要使用的日历的电子邮件地址, 可以在 Google 日历网页版的日历设置中查看 (在“日历网址”部分),您也可以查找 的 calendarList.list() 调用。
  • event 是要创建的事件,其中包含所有必要详细信息(例如 start) 和结束。仅有的两个必填字段是 startend。请参阅 有关完整事件集的 event 参考文档 字段。

要成功创建事件,您需要:

  • 将 OAuth 范围设置为 https://www.googleapis.com/auth/calendar, 您拥有该用户的日历的编辑权限。
  • 确保通过身份验证的用户拥有对该日历的写入权限, 您提供的 calendarId(例如,通过调用 calendarList.get()适用于 calendarId 并检查 accessRole)。

添加事件元数据

您可以在创建日历活动时选择添加活动元数据。如果您 选择在创建过程中不添加元数据,您可以使用 events.update();但有些字段 只能在活动触发期间设置 events.insert() 操作。

位置

在位置字段中添加地址可启用一些功能,例如:

“该出发了”或显示包含路线的地图。

事件 ID

创建活动时,您可以选择生成自己的活动 ID

并且符合我们的格式要求这样,您可以将实体 与 Google 日历中的活动保持同步。它还 防止在操作失败后某个时间点创建重复的活动 已成功在日历后端执行。如果拒绝 事件 ID,服务器会为您生成一个。请参阅事件 ID 参考

参加者

您创建的活动会显示在以下所有主 Google 日历中:

同一活动 ID 所关联的参加者。如果您将 插入请求向 true 发送 sendNotifications,参加者将 还会收到有关该活动的电子邮件通知。使用 针对多名参加者的指南 。

以下示例演示了如何创建事件并设置其元数据:

为活动添加云端硬盘附件

您可以附加 Google 云端硬盘 如 Google 文档中的会议记录、Google 文档中的预算 表格、Google 幻灯片中的演示文稿 将相关的 Google 云端硬盘文件与您的日历活动相关联。您可以将 创建活动时添加附件 events.insert() 或更高版本(作为 更新,例如使用 events.patch()

将 Google 云端硬盘文件附加到活动的过程包含两个部分:

  1. 获取文件 alternateLink 网址、titlemimeType Drive API Files 资源,通常是 使用 files.get() 方法。
  2. 使用请求中设置的 attachments 字段创建或更新事件 并将 supportsAttachments 参数设为 true

以下代码示例演示了如何更新现有要添加的事件 附件:

Java

public static void addAttachment(Calendar calendarService, Drive driveService, String calendarId,
    String eventId, String fileId) throws IOException {
  File file = driveService.files().get(fileId).execute();
  Event event = calendarService.events().get(calendarId, eventId).execute();

  List<EventAttachment> attachments = event.getAttachments();
  if (attachments == null) {
    attachments = new ArrayList<EventAttachment>();
  }
  attachments.add(new EventAttachment()
      .setFileUrl(file.getAlternateLink())
      .setMimeType(file.getMimeType())
      .setTitle(file.getTitle()));

  Event changes = new Event()
      .setAttachments(attachments);
  calendarService.events().patch(calendarId, eventId, changes)
      .setSupportsAttachments(true)
      .execute();
}

PHP

function addAttachment($calendarService, $driveService, $calendarId, $eventId, $fileId) {
  $file = $driveService->files->get($fileId);
  $event = $calendarService->events->get($calendarId, $eventId);
  $attachments = $event->attachments;

  $attachments[] = array(
    'fileUrl' => $file->alternateLink,
    'mimeType' => $file->mimeType,
    'title' => $file->title
  );
  $changes = new Google_Service_Calendar_Event(array(
    'attachments' => $attachments
  ));

  $calendarService->events->patch($calendarId, $eventId, $changes, array(
    'supportsAttachments' => TRUE
  ));
}

Python

def add_attachment(calendarService, driveService, calendarId, eventId, fileId):
    file = driveService.files().get(fileId=fileId).execute()
    event = calendarService.events().get(calendarId=calendarId,
                                         eventId=eventId).execute()

    attachments = event.get('attachments', [])
    attachments.append({
        'fileUrl': file['alternateLink'],
        'mimeType': file['mimeType'],
        'title': file['title']
    })

    changes = {
        'attachments': attachments
    }
    calendarService.events().patch(calendarId=calendarId, eventId=eventId,
                                   body=changes,
                                   supportsAttachments=True).execute()

为活动添加视频和电话会议

您可以将事件与 HangoutsGoogle Meet 会议 让您的用户通过电话或视频通话进行远程会议。

conferenceData 字段 用于读取、复制和清除现有会议详细信息;也可以是 用于请求生成新会议。要允许创建和 修改会议详细信息,设置 conferenceDataVersion 请求 参数设为 1

目前支持三种类型的 conferenceData,分别以 conferenceData.conferenceSolution.key.type

  1. 个人用户版 Hangouts (eventHangout)
  2. 面向用户的 传统版 Hangouts (已弃用;eventNamedHangout
  3. Google Meet (hangoutsMeet)

您可以了解某个日历服务的任何指定日历支持哪种会议类型, 通过查看 API 中的 conferenceProperties.allowedConferenceSolutionTypes calendarscalendarList 个集合。您还可以 了解用户是否更愿意 通过检查autoAddHangoutssettings”集合。

type 之外,conferenceSolution 还提供 nameiconUri 字段,您可以使用这些字段来表示会议解决方案,如下所示 如下:

JavaScript

const solution = event.conferenceData.conferenceSolution;

const content = document.getElementById("content");
const text = document.createTextNode("Join " + solution.name);
const icon = document.createElement("img");
icon.src = solution.iconUri;

content.appendChild(icon);
content.appendChild(text);

您可以提供 createRequest,以便为活动创建新会议,具体方法是: 新生成的 requestId,可以是随机 string。会议为 但您可以随时查看请求的状态 告知用户所发生的情况

例如,如需为现有活动请求生成会议,请使用以下代码:

JavaScript

const eventPatch = {
  conferenceData: {
    createRequest: {requestId: "7qxalsvy0e"}
  }
};

gapi.client.calendar.events.patch({
  calendarId: "primary",
  eventId: "7cbh8rpc10lrc0ckih9tafss99",
  resource: eventPatch,
  sendNotifications: true,
  conferenceDataVersion: 1
}).execute(function(event) {
  console.log("Conference created for event: %s", event.htmlLink);
});

此调用的即时响应可能尚未包含完全填充的 conferenceData;则会返回 pending 状态代码, 状态 字段。收到会议信息后,状态代码会更改为 success 填充。entryPoints 字段包含 您的用户可通过电话 URI 拨号加入会议。

如果您希望在同一项活动中安排多个日历活动, 您可将一个活动中的整个conferenceData复制到 另一个。

复制操作在某些情况下非常有用。例如,假设您正在开发 为候选人和 即您不仅希望保护面试官的身份, 希望确保所有参与者都加入同一场电话会议。
