Hi,
I create one project with asp.net web-form to invoke google calendar API and insert and update events on google calendar. My Code works fine in development server but I am facing problem when i host in IIS . Problem is related to Access-token
and Authorization in IIS.
As per google console, I know first i need to authorize and then exchange the code for token.
Here is my code
public void ImportGoogleEvents(string EventSummary, string EventLocation, string EventDescription, DateTime EventStartDateTime, DateTime EventEndDateTime, string CustomCalenderName, [Optional] string StartDatetimeZone, [Optional] string EndDatetimeZone, [Optional] string attachmentsfileUrl)
{
ClientSecrets secrets = new ClientSecrets()
{
ClientId = clientId,
ClientSecret = clientSecret
};
var valid_token = "VALID TOKEN HERE"; // This i got from Google PlayGround and it works fine but when i close Google Playground or Token Expires it starts generating error.
var token = new Google.Apis.Auth.OAuth2.Responses.TokenResponse()
{
AccessToken = valid_token,
ExpiresInSeconds = 3600,
IssuedUtc = DateTime.Now
};
var apiFlow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = new ClientSecrets
{
ClientId = clientId,
ClientSecret = clientSecret
}
});
UserCredential credential = new UserCredential(apiFlow, "User Id here", token);
bool success = credential.RefreshTokenAsync(CancellationToken.None).Result;
token = credential.Token;
if (credential != null)
{
var calendarService = new Google.Apis.Calendar.v3.CalendarService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = ApplicationName
}
);
if (calendarService != null)
{
var list = calendarService.CalendarList.List().Execute();
var listcnt = list.Items;
var calendar = list.Items.SingleOrDefault(c => c.Summary == CustomCalenderName.Trim());
if (calendar != null)
{
Google.Apis.Calendar.v3.Data.Event calendarEvent = new Google.Apis.Calendar.v3.Data.Event();
calendarEvent.Summary = EventSummary;
calendarEvent.Location = EventLocation;
calendarEvent.Description = EventDescription;
calendarEvent.Start = new Google.Apis.Calendar.v3.Data.EventDateTime
{
DateTime = EventStartDateTime /*new DateTime(StartDate.Year, StartDate.Month, StartDate.Day, StartDate.Hour, StartDate.Minute, StartDate.Second)*/,
TimeZone = StartDatetimeZone
};
calendarEvent.End = new Google.Apis.Calendar.v3.Data.EventDateTime
{
DateTime = EventEndDateTime /*new DateTime(EndDate.Year, EndDate.Month, EndDate.Day, EndDate.Hour, EndDate.Minute, EndDate.Second)*/,
TimeZone = EndDatetimeZone
};
calendarEvent.Recurrence = new List<string>();
var newEventRequest = calendarService.Events.Insert(calendarEvent, calendar.Id);
var eventResult = newEventRequest.Execute();
}
}
}
}
I will be thankful if someone who already worked and can help me on this .
Thanks in Advance,
