[英]Google Calendar API with ASP.NET
我對使用 Google Calendar API 在 ASP.NET webforms (C#) 中添加/修改事件感到困惑。
我不確定我是否需要 oAuth 或什么。 我的應用程序在我自己的服務器上訪問我自己的域和我自己的日歷。 我不需要其他用戶讓我訪問他們的日歷; 我只需要通過我的應用程序訪問我自己的。
在我的一個 aspx 頁面上,我想將事件信息發送到我的 Google 日歷以添加(或稍后修改)事件。
我檢查了各種代碼示例和 Google 入門指南。 我只是不清楚到底需要什么。 我已經設置了一個 API 密鑰和一個 oAuth2 客戶端 ID。 谷歌的說明讓我轉了一圈,這可能是因為我需要澄清什么是需要的。
有人可以澄清我的困惑並指出正確的方向嗎?
調用谷歌雲 oauth2 保護資源
從您的服務器到谷歌服務器
無需用戶交互
訪問您自己的數據
使用 C#
代碼 :
var private_key = @"-----BEGIN PRIVATE KEY-ccc-END PRIVATE KEY-----\n";
string calendarId = @"xxxxxxxxxxxxx@group.calendar.google.com";
var client_email = @"my-google-calender@xxx.iam.gserviceaccount.com";
var credential =
new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(client_email)
{
Scopes = new string[] { CalendarService.Scope.Calendar }
}.FromPrivateKey(private_key));
var service = new CalendarService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
});
使用服務方法獲取數據
可以從此鏈接生成私鑰和 client_email
日歷 ID 可以在 calendar.google.com 上找到
您必須與 client_email 共享您的日歷,請參閱演示
