asp.net-mvc-4 - 在 mvc 4 应用程序中获取 gmail 日历事件

Question

我正在开发 mvc 4 Web 应用程序。我想实现一个功能，其中场景如下 - 将有 gmail id 作为输入：abc@gmail.com。当用户输入此内容时，应用程序应获取相应电子邮件 ID 的所有日历事件并显示它们。

我经历过这个-

请检查以下步骤。

1. 添加谷歌数据 API SDK。

2. 试试这段代码。我为一个项目编写了这段代码，但我删除了一些与谷歌日历无关的代码。如果您不想使用 SDK，您可以简单地根据规范对您的日历链接执行 http-get 或 http-post。

           CalendarService service = new CalendarService("A.Name");
           const string GOOGLE_CALENDAR_FEED = "https://www.google.com/calendar/feeds/";
           const string GOOGLE_CALENDAR_DEFAULT_ALL_CALENDAR_FULL = "default/allcalendars/full";
           const string GOOGLE_CALENDAR_ALL_PRIVATE_FULL = "private/full";
   
           private void SetUserCredentials() {
               var userName = ConfigurationManager.AppSettings["GoogleUserName"];
               var passWord = Security.DecryptString(ConfigurationManager.AppSettings["GooglePasswrod"]).ToInsecureString();
               if (userName != null && userName.Length > 0) {
                   service.setUserCredentials(userName, passWord);
               }
           }        
   
           private CalendarFeed GetCalendarsFeed() {
               CalendarQuery calendarQuery = new CalendarQuery();
               calendarQuery.Uri = new Uri(GOOGLE_CALENDAR_FEED + GOOGLE_CALENDAR_DEFAULT_ALL_CALENDAR_FULL);
   
               CalendarFeed resultFeed = (CalendarFeed)service.Query(calendarQuery);
               return resultFeed;
           }
   
       private TherapistTimeSlots GetTimeSlots(CalendarEntry entry2) {
   
   
       string feedstring = entry2.Id.AbsoluteUri.Substring(63);
       var postUristring = string.Format("{0}{1}/{2}", GOOGLE_CALENDAR_FEED, feedstring, GOOGLE_CALENDAR_ALL_PRIVATE_FULL);
   
       EventFeed eventFeed = GetEventFeed(postUristring);
       slot.Events = new List<Event>();
   
       if (eventFeed != null) {
           var orderEventList = (from entity in eventFeed.Entries
                                 from timeslot in ((EventEntry)entity).Times
                                 orderby timeslot.StartTime
                                 select entity).ToList();
   
       }
       return slot;
   }
   
   private EventFeed GetEventFeed(string postUristring) {
   
       var eventQuery = new EventQuery();
       eventQuery.Uri = new Uri(postUristring);
       var h = Convert.ToInt32(DateTime.Now.ToString("HH", System.Globalization.DateTimeFormatInfo.InvariantInfo));
       eventQuery.StartTime = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, h, 0, 0);
       eventQuery.EndTime = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, h + 2, 0, 0);
       try {
           EventFeed eventFeed = service.Query(eventQuery) as EventFeed;
           return eventFeed;
       }
       catch (Exception ex) {
           /*
            * http://groups.google.com/group/google-calendar-help-dataapi/browse_thread/thread/1c1309d9e6bd9be7
            * 
            *  Unfortunately, the calendar API will always issue a redirect to give you a 
               gsessionid that will optimize your subsequent requests on our servers. 
               Using the GData client library should be transparent for you as it is taking 
               care of handling those redirect; but there might some times where this error 
               occurs as you may have noticed. 
               The best way to work around this is to catche the Exception and re-send the 
               request as there is nothing else you can do on your part.
