Is there any code example of a desktop application how to authorize to Google Drive service and upload a file?
Currently I have:
var parameters = new OAuth2Parameters
{
ClientId = ClientCredentials.ClientId,
ClientSecret = ClientCredentials.ClientSecret,
RedirectUri = ClientCredentials.RedirectUris[0],
Scope = ClientCredentials.GetScopes()
};
string url = OAuthUtil.CreateOAuth2AuthorizationUrl(parameters);
// Open url, click to allow and copy secret code
parameters.AccessCode = secretCodeFromBrowser;
OAuthUtil.GetAccessToken(parameters);
string accessToken = parameters.AccessToken;
// So, there is the access token
But what are the next steps? As I see from examples I should get IAuthenticator instance and pass it into constructor of DriveService class... How to get an instance of IAuthenticator? If my above code is correct... Thanks in advance.
Here is a complete command-line sample in C# to upload a file to Google Drive:
using System;
using System.Diagnostics;
using DotNetOpenAuth.OAuth2;
using Google.Apis.Authentication.OAuth2;
using Google.Apis.Authentication.OAuth2.DotNetOpenAuth;
using Google.Apis.Drive.v2;
using Google.Apis.Drive.v2.Data;
using Google.Apis.Util;
namespace GoogleDriveSamples
{
class DriveCommandLineSample
{
static void Main(string[] args)
{
String CLIENT_ID = "YOUR_CLIENT_ID";
String CLIENT_SECRET = "YOUR_CLIENT_SECRET";
// Register the authenticator and create the service
var provider = new NativeApplicationClient(GoogleAuthenticationServer.Description, CLIENT_ID, CLIENT_SECRET);
var auth = new OAuth2Authenticator<NativeApplicationClient>(provider, GetAuthorization);
{
Authenticator = auth
});
File body = new File();
body.Title = "My document";
body.Description = "A test document";
body.MimeType = "text/plain";
byte[] byteArray = System.IO.File.ReadAllBytes("document.txt");
System.IO.MemoryStream stream = new System.IO.MemoryStream(byteArray);
FilesResource.InsertMediaUpload request = service.Files.Insert(body, stream, "text/plain");
request.Upload();
File file = request.ResponseBody;
Console.WriteLine("File id: " + file.Id);
Console.ReadLine();
}
private static IAuthorizationState GetAuthorization(NativeApplicationClient arg)
{
// Get the auth URL:
IAuthorizationState state = new AuthorizationState(new[] { DriveService.Scopes.Drive.GetStringValue() });
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();
Console.WriteLine();
// Retrieve the access token by using the authorization code:
return arg.ProcessUserAuthorization(authCode, state);
}
}
}
