Google API v3 for dotnet; using the calendar with an API key
11,653
Hi for me this works:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Google.Apis.Calendar;
using Google.Apis.Calendar.v3;
using Google.Apis.Authentication;
using Google.Apis.Authentication.OAuth2;
using Google.Apis.Authentication.OAuth2.DotNetOpenAuth;
using DotNetOpenAuth.OAuth2;
using System.Diagnostics;
using Google.Apis.Calendar.v3.Data;
namespace consoleGoogleResearch
{
class Program
{
public static void Main(string[] args)
{
// Register the authenticator. The Client ID and secret have to be copied from the API Access
// tab on the Google APIs Console.
var provider = new NativeApplicationClient(GoogleAuthenticationServer.Description);
provider.ClientIdentifier = "fill_in_yours";
provider.ClientSecret = "fill_in_yours";
// Create the service. This will automatically call the authenticator.
var service = new CalendarService(new OAuth2Authenticator<NativeApplicationClient>(provider, GetAuthentication));
Google.Apis.Calendar.v3.CalendarListResource.ListRequest clrq = service.CalendarList.List();
var result = clrq.Fetch();
if (result.Error != null)
{
Console.WriteLine(result.Error.Message);
Console.ReadKey();
return;
}
Console.WriteLine("Calendars: ");
foreach (CalendarListEntry calendar in result.Items)
{
Console.WriteLine("{0}", calendar.Id);
Console.WriteLine("\tAppointments:");
Google.Apis.Calendar.v3.EventsResource.ListRequest elr = service.Events.List(calendar.Id);
var events = elr.Fetch();
foreach (Event e in events.Items)
{
Console.WriteLine("\t From: {0} To: {1} Description: {2}, Location: {3}", e.Start, e.End, e.Description, e.Location);
}
}
Console.ReadKey();
}
private static IAuthorizationState GetAuthentication(NativeApplicationClient arg)
{
// Get the auth URL:
//IAuthorizationState state = new AuthorizationState(new[] { CalendarService.Scopes.Calendar.ToString() });
IAuthorizationState state = new AuthorizationState(new[] { "https://www.google.com/calendar/feeds" });
state.Callback = new Uri(NativeApplicationClient.OutOfBandCallbackUrl);
Uri authUri = arg.RequestUserAuthorization(state);
// Request authorization from the user (by opening a browser window):
Process.Start(authUri.ToString());
Console.Write(" Authorization Code: ");
string authCode = Console.ReadLine();
// Retrieve the access token by using the authorization code:
return arg.ProcessUserAuthorization(authCode, state);
}
}
}

I'm trying to read my own Google calendar with the v3 API (http://code.google.com/p/google-api-dotnet-client/). What I eventually want is to display my own calendar from Google Calendar on my site through a custom control (and later on let people make custom appointments). Every sample I'm reading is based on the premise that I should manually give access to my data. Still in the Google API console I created an application with a API key. I’m trying to create a valid IAuthentication for my code. Never the less I don’t get which authentication I have to use. Below is a miserable attempt, who can help me with this?
public void TestMethod1() { // http://code.google.com/p/google-api-dotnet-client/wiki/OAuth2 NativeApplicationClient provider = NativeApplicationClient(GoogleAuthenticationServer.Description); NativeApplicationClient(GoogleAuthenticationServer.Description); provider.ClientIdentifier = "x"; provider.ClientSecret = "x"; var auth = new OAuth2Authenticator<NativeApplicationClient>(provider, GetAuthorization); Google.Apis.Calendar.v3.CalendarService service = new Google.Apis.Calendar.v3.CalendarService(auth); var result = service.Events.List("primary").Fetch(); Assert.IsTrue(result.Items.Count > 0); } private static IAuthorizationState GetAuthorization(NativeApplicationClient arg) { IAuthorizationState state = new AuthorizationState(new[] { CalendarService.Scopes.Calendar.GetStringValue() }); return arg.ProcessUserAuthorization("", state); }
