c# - 如何实现OAUTH 2.0访问Google Analytics(分析)

Question

我已经读到Google停止了以前的身份验证方法来访问Google API，因此现在我们必须使用该OAuth2身份验证方法。我已经读到我们必须进入开发人员控制台并获取ClientID和Client Secret，以便我们可以执行身份验证。但是我在编写必要的更改以成功登录时遇到了很多麻烦。

我正在搜索准则以在登录级别进行更改。我尝试应用一些在网络上找到的代码，但未成功。关于开发者控制台我已经有一个带有ClientID和Secret的项目，所以我没有生成一个新项目，而是使用了已经生成的ClientID和Secret。

这是Google更改之前的工作代码：

    {
    /// <summary>
    /// Summary description for GoogleAnalytics
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    [System.Web.Script.Services.ScriptService]
    public class GoogleAnalytics : System.Web.Services.WebService
    {
        [WebMethod]
        public string GetAnalyticsPageViews()
        {
            string returnValue = string.Empty;

            object cacheObjPageViewsCount = CacheService.Get(CacheService.ANALYTICSPAGEVIEWS);

            if (cacheObjPageViewsCount != null)
                returnValue = cacheObjPageViewsCount as string;
            else
            {
                try
                {
                    string userName = Configurations.GetConfigurationValueAsString("GoogleAnalyticsUsername");
                    string passWord = Configurations.GetConfigurationValueAsString("GoogleAnalyticsPassword");
                    string profileId = Configurations.GetConfigurationValueAsString("GoogleAnalyticsProfileId");

                    const string dataFeedUrl = "https://www.googleapis.com/analytics/v2.4/data";

                    AnalyticsService service = new AnalyticsService("ApplicationName");
                    if (!string.IsNullOrEmpty(userName))
                    {
                        service.setUserCredentials(userName, passWord);
                    }

                    DataQuery query1 = new DataQuery(dataFeedUrl);
                    query1.Ids = "ga:" + profileId;
                    query1.Metrics = "ga:visits";
                    query1.Sort = "ga:visits";
                    query1.GAStartDate = DateTime.Now.AddYears(-1).ToString("yyyy-MM-dd");
                    query1.GAEndDate = DateTime.Now.ToString("yyyy-MM-dd");
                    query1.StartIndex = 1;
                    DataFeed dataFeedVisits = service.Query(query1);
                    DataEntry dataEntry = (DataEntry)dataFeedVisits.Entries[0];
                    returnValue = dataEntry.Metrics[0].Value;
                }
                catch (Exception exc)
                {
                    LogService.LogException(exc);
                    returnValue = string.Empty;
                }

                CacheService.Add(CacheService.PP_ANALYTICSPAGEVIEWS_COUNT_CACHE_KEY, returnValue);
            }

            return returnValue;
        }
    }
}

这是我尝试执行的更改

而不是使用if“ service.setUserCredentials（userName，passWord）;”
我使用“ GoogleOAutho2.authenticate（）;”
结果是它打开了一个新页面，并出现以下错误：请求： http://localhost:60279/authorize/中的重定向URI与注册的重定向URI不匹配。

我不明白为什么即时通讯会发送到新页面，而以前的身份验证方法却没有发生，我在哪里失踪？

提前致谢，

我发送到的页面：

https://accounts.google.com/o/oauth2/auth?access_type=offline&response_type=code&client_id= clientid＆redirect_uri = http://localhost:60279/authorize/&scope=https://www.googleapis.com/auth/analytics%20https://www.googleapis.com/auth/analytics.edit%20https://www.googleapis.com/auth/analytics.manage.users%20https://www.googleapis.com/auth/analytics.readonly

不知道这是否有帮助。我没有使用这些相同的类，甚至没有使用C＃。我使用的方法是直接HTTP调用。在我的实现中，我调用https://accounts.google.com/o/oauth2/auth作为redirect_uri参数传递在API控制台中指定的相同值（请参见屏幕截图）。

是否可以在任何地方通过/指定？
