Google Calendar API v3 – 在服务器上部署时请求超时

我试图登录localhost，一切正常。

代码：

public static bool LoginGoogleCalendar(string clientId, string clientSecret, string idGCalendarUser, string calendarServiceScope, string folder) { try { UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync( new ClientSecrets { ClientId = clientId, ClientSecret = clientSecret, }, new[] { calendarServiceScope }, idGCalendarUser, CancellationToken.None, new FileDataStore(folder)).Result; return true; } catch (Exception ex) { Elmah.ErrorSignal.FromCurrentContext().Raise(ex); return false; } } 

（我正确设置了fileDataStore的授权）

在Google Developers Console中：

重定向URI： http://localhost/authorize/ Javascript起源： http://localhost:8081

我使用Visual Studio 2013，IIS 8

当我尝试登录服务器时，会阻塞整个服务器几分钟，之后的答案是：System.Web.HttpException请求超时。

在Google Developers Console中：

重定向URI： http://pippo.pluto.it/authorize/ ： http://pippo.pluto.it/authorize/ Javascript起源： http://pippo.pluto.it ： http://pippo.pluto.it

在服务器上：IIS 7

我走到了同样的问题。 互联网上的很多例子告诉你使用这个课程。 对于Web应用程序，这不是要使用的类。 这个类适用于“离线”应用程序，但是当你在IIS服务器上使用这个类时，它会尝试打开服务器上的弹出窗口，但它不会让它。

我使用的课程：GoogleAuthorizationCodeFlow

 using Google.Apis.Analytics.v3; using Google.Apis.Auth.OAuth2; using Google.Apis.Auth.OAuth2.Flows; using Google.Apis.Auth.OAuth2.Requests; using Google.Apis.Auth.OAuth2.Web; using Google.Apis.Services; using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading; using System.Threading.Tasks; using System.Web; namespace GoogleOauth2DemoWebApp { public class GoogleOauth { public AnalyticsService Handle(string _userId, string _connectionString, string _googleRedirectUri, string _applicationName, string[] _scopes) { try { string UserId = _userId;//The user ID wil be for examlpe the users gmail address. AnalyticsService service; GoogleAuthorizationCodeFlow flow; //use extended class to create google authorization code flow flow = new ForceOfflineGoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer { DataStore = new DbDataStore(_connectionString),//DataStore class to save the token in a SQL database. ClientSecrets = new ClientSecrets { ClientId = "XXX-YOUR CLIENTID-XXX", ClientSecret = "XXX-YOURCLIENTSECRET-XXX" }, Scopes = _scopes, }); var uri = HttpContext.Current.Request.Url.ToString(); string redirecturi = _googleRedirectUri;//This is the redirect URL set in google developer console. var code = HttpContext.Current.Request["code"]; if (code != null) { var token = flow.ExchangeCodeForTokenAsync(UserId, code, uri.Substring(0, uri.IndexOf("?")), CancellationToken.None).Result; var test = HttpContext.Current.Request["state"]; // Extract the right state. var oauthState = AuthWebUtility.ExtracRedirectFromState( flow.DataStore, UserId, HttpContext.Current.Request["state"]).Result; HttpContext.Current.Response.Redirect(oauthState); } else { var result = new AuthorizationCodeWebApp(flow, redirecturi, uri).AuthorizeAsync(UserId, CancellationToken.None).Result; if (result.RedirectUri != null) { // Redirect the user to the authorization server. HttpContext.Current.Response.Redirect(result.RedirectUri); } else { // The data store contains the user credential, so the user has been already authenticated. service = new AnalyticsService(new BaseClientService.Initializer() { HttpClientInitializer = result.Credential, ApplicationName = _applicationName }); return service; } } return null; } catch (Exception ex) { throw ex; } } internal class ForceOfflineGoogleAuthorizationCodeFlow : GoogleAuthorizationCodeFlow { public ForceOfflineGoogleAuthorizationCodeFlow(GoogleAuthorizationCodeFlow.Initializer initializer) : base(initializer) { } public override AuthorizationCodeRequestUrl CreateAuthorizationCodeRequest(string redirectUri) { var ss = new Google.Apis.Auth.OAuth2.Requests.GoogleAuthorizationCodeRequestUrl(new Uri(AuthorizationServerUrl)); ss.AccessType = "offline"; ss.ApprovalPrompt = "force"; ss.ClientId = ClientSecrets.ClientId; ss.Scope = string.Join(" ", Scopes); ss.RedirectUri = redirectUri; return ss; } }; } } 

我也用一个DataStore类。 将令牌保存到服务器上的文件不是最佳做法。 我用了一个SQL数据库。

数据存储类的示例。 它会为你制作一张桌子，而不是最好的方法，但测试足够好。

 using Google.Apis.Json; using Google.Apis.Util.Store; using System; using System.Collections.Generic; using System.Data.SqlClient; using System.Linq; using System.Text; using System.Threading.Tasks; namespace GoogleOauth2DemoWebApp { public class DbDataStore : IDataStore { readonly string connectionString; public string ConnectionString { get { return connectionString; } } private Boolean _ConnectionExists { get; set; } public Boolean connectionExists { get { return _ConnectionExists; } } ///

使用class级：

 GoogleOauth g = new GoogleOauth(); AnalyticsService service = g.Handle(userEmailAddress, connectionString, redirectUrl, "YOURAPLICATIONNAME", new[] {AnalyticsService.Scope.AnalyticsReadonly}); DataResource.RealtimeResource.GetRequest request = service.Data.Realtime.Get(String.Format("ga:{0}", profileId), "rt:activeUsers"); RealtimeData feed = request.Execute(); 

如果有人感兴趣，我可以将示例项目上传到github。
