週期性活動

本文件將說明如何處理週期性活動及其執行個體。

建立週期性活動

建立週期性活動的方式與使用 event 資源的 recurrence 欄位組合「建立」一般 (單一) 活動類似。

print response.id

存取執行個體

如要查看指定節點的所有執行個體您可以使用 events.instances() 要求，

預設的 events.list() 要求只會傳回單一活動、週期性活動，例外狀況；非例外狀況的執行個體則不會傳回。如果 singleEvents 參數如果設為 true，則所有個別例項都會出現在結果中，但基礎的週期性事件則不會。當擁有有空/忙碌權限的使用者查詢 events.list() 時，則等同於 singleEvent 為 true 的行為。如要進一步瞭解存取控制清單規則，請參閱 Acl。

個別例項與單一事件相似。有別於家長週期性活動執行個體並未設定 recurrence 欄位。

下列事件欄位專屬於執行個體：

recurringEventId：此執行個體所屬的父項週期性事件 ID
originalStartTime：根據父項週期性事件中的重複週期資料，啟動這個執行個體的時間。如果執行個體重新排程，則此時間可能會與實際的 start 時間不同。它可明確識別週期性活動系列中的例項，即使執行個體已移動也一樣。

修改或刪除執行個體

如要修改單一執行個體 (建立例外狀況)，用戶端應用程式必須先擷取該執行個體，然後傳送已授權的 PUT 要求，傳送至主體中含有更新後的資料的執行個體編輯網址以進行更新。網址格式為：

https://www.googleapis.com/calendar/v3/calendars/calendarId/events/instanceId

使用適當的值取代 calendarId 和 instanceId。

注意： 特殊 calendarId 值 primary 可用來參照已驗證使用者的主要日曆。

成功時，伺服器會傳回 HTTP 200 OK 狀態碼以及更新的執行個體。以下範例說明如何取消週期性活動的執行個體。

print response.updated

修改下列所有執行個體

如要在特定 (目標) 例項當天或之後變更週期性活動的所有例項，您必須發出兩個不同的 API 要求這些要求會將原本的週期性活動拆成兩個部分：原始的快照不會變更執行個體，而新的週期性活動套用變更的執行個體：

呼叫 events.update() 即可：修剪待更新執行個體的原始週期性活動。方法是將 RRULE 的 UNTIL 元件，指向第一個目標執行個體您也可以設定 COUNT 元件，而不 UNTIL。
呼叫 events.insert() 即可：建立新的週期性活動，並在其中的所有資料與原始活動完全一樣，但除了您嘗試進行的變更新週期性活動的開始時間必須設為目標執行個體

本例說明如何將位置從第三個值變更為「其他位置」上一個例子中的週期性事件例項。
