请求中的重定向URI：http：// localhost：12349 / authorize /与注册的重定向URI不匹配

Question

我在尝试运行我的c＃控制台应用程序时遇到此错误...我正在尝试调用google calender api v3来获取日历并将事件添加到日历。根据google-api-dotnet-client的示例代码，我这样做。（https://code.google.com/p/google-api-dotnet-client/source/browse/Calendar.VB.ConsoleApp/Program.vb?repo=samples）这是vb.net代码。我在将其转换为c＃代码后使用此示例。

这是我的代码：

class Program
{
    static void Main(string[] args)
    {
        try
        {
            new Program().Run().Wait();
        }
        catch (AggregateException ex)
        {
            foreach (var e in ex.InnerExceptions)
            {
                Console.WriteLine("ERROR: " + e.Message);
            }
        }
    }

    private async Task Run()
    {
        UserCredential credential;
        IList<string> scopes = new List<string>();

        CalendarService service;
        scopes.Add(CalendarService.Scope.Calendar);


        using (var stream = new FileStream("client_secrets.json", FileMode.Open, FileAccess.Read))
        {
            // problem occuring during executing this statement.
            credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
                GoogleClientSecrets.Load(stream).Secrets,
                scopes,
                "user", CancellationToken.None, new FileDataStore("Calender.SampleApp") );
        }

        BaseClientService.Initializer initializer = new BaseClientService.Initializer();
        initializer.HttpClientInitializer = credential;
        initializer.ApplicationName = "C# Calendar Sample";

        service = new CalendarService(initializer);

        Event newEvent = new Event();

        newEvent.Summary = "Appointment";
        newEvent.Description = "Need to meet my Uncle";

        IList<EventReminder> reminders = new List<EventReminder>();
        reminders.Add(new EventReminder { Method = "sms", Minutes = 10 });
        newEvent.Reminders = new Event.RemindersData { UseDefault = false, Overrides = reminders };

        newEvent.Recurrence = new String[] { "DTSTART;TZID=Bangladesh Standard Time:20140124T163000;RRULE:FREQ=DAILY" };

        IList<EventAttendee> attendees = new List<EventAttendee>();
        attendees.Add(new EventAttendee { Email = "hannan.cse.m@gmail.com", Organizer = true, DisplayName = "Hannan" });
        newEvent.Attendees = attendees;

        newEvent.GuestsCanInviteOthers = false;
        newEvent.GuestsCanModify = false;
        newEvent.GuestsCanSeeOtherGuests = false;
        newEvent.Location = "Dhaka, Bangladesh";
        newEvent.Start = new EventDateTime { DateTime = DateTime.Now, TimeZone = "Bangladesh Standard Time" };

        Event recurringEvent = service.Events.Insert(newEvent, "primary").Execute();

        var list = await service.CalendarList.List().ExecuteAsync();
    }
}

这是我的GoogleDevelopers控制台项目中的重定向URI。

Redirect URIs: http://localhost:7744/authorize/

这是浏览器中显示的错误消息。

我找不到任何解决此问题的方法。一些帮助将是值得的。我还在stackoverflow中搜索所有已发布的帖子。但我找不到它的解决方案。

Answer 1

我认为您在GoogleDevelopers Console中“创建客户端ID”时做错了什么。确保您已在应用程序类型中选择“已安装的应用程序”以从控制台应用程序访问您的项目。

查看附图。根据请求类型，您必须创建clientid 和您在Google Developers Console中注册的应用程序中的信誉。

在进行身份验证时，您无需在控制台应用程序中定义重定向uri。

我在一个简单的测试程序（https://ctrlq.org/google.apps.script/docs/guides/rest/quickstart/dotnet.html）上遇到了这个错误，它碰巧是client_secret.json是错误的，再次下载它就有用了。
