本文介绍了带有ASP.NET的Google Calendar API的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

对于使用Google Calendar API在ASP.NET网络表单(C#)中添加/修改事件感到困惑.

I'm confused about using the Google Calendar API for adding/modifying events in ASP.NET webforms (C#).

我不确定是否需要oAuth或什么.我的应用程序在我自己的服务器上，用于访问我自己的域和日历.我不需要其他用户给我访问他们的日历的权限；我只需要通过我的应用程序访问自己的内容即可.

I'm not sure if I need oAuth or what. My app is on my own server accessing my own domain and my own calendar. I don't need other users to give me access to their calendar; I only need to access my own via my app.

在我的aspx页面之一上，我想将事件信息发送到我的Google日历以添加(或以后修改)该事件.

On on one of my aspx pages, I'd like to send event info to my Google calendar to add (or later modify) the event.

我检查了各种代码示例和Google入门指南.我只是不清楚确切需要什么.我已经设置了API密钥和oAuth2客户端ID. Google的说明使我发了圈，这很可能是由于我需要澄清所需要的内容.

I've checked all kinds of code examples and the Google getting started guides. I'm just not clear on what exactly is needed. I've set up an API key and an oAuth2 client ID. The Google instructions have sent me in circles and it's likely due to my needing clarification on what's need.

有人可以消除我的困惑并指出正确的方向吗?

Can someone please clear-up my confusion and point me in the right direction?

摘要:

呼叫Google clood oauth2受保护的资源

To Call a google clould oauth2 protected resource

从您的服务器到Google服务器

From your server to google server

没有用户交互

访问您自己的数据

使用C#

代码:

    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 service 方法获取数据

Use service methods to get the data

生成私钥和client_email. "noreferrer>此链接

Private Key and client_email can be generated from this link

日历ID可以在calendar.google.com

Calendar Id can be found on calendar.google.com

您必须与client_email共享您的日历查看演示

                }
             };
    }
}

第22步:用您的json文件名替换json文件名

  string jsonFile = "xxxxxxx-xxxxxxxx.json";

步骤23:将日历ID替换为步骤14中的calendarId

 string calendarId = @"xxxxxxxxxxxxx@group.calendar.google.com";

第24步:运行应用
