远程服务器返回错误：(404) 未找到。 谷歌在 C# 中的实现

Question

我正在使用 OAuth2 凭据，但出现 404 错误：

using Google.Analytics;
using Google.GData.Analytics;

    void Analytics()
        {
            try
            {
                string userName = ConfigurationManager.AppSettings["username"];
                string passWord = ConfigurationManager.AppSettings["password"];
                string gkey = "key=api _key";
                string dataFeedUrl = "https://www.googleapis.com/analytics/v3/data/ga";//+ gkey;
                AccountQuery query = new AccountQuery();
                AnalyticsService service = new AnalyticsService("Web App");
                service.setUserCredentials(userName, passWord);

                DataQuery query1 = new DataQuery(dataFeedUrl);
                query1.Ids = "ga:123456789";
                query1.Metrics = "ga:visits,ga:sessions,ga:pageValue,ga:bounces,ga:bounceRate,ga:pageviews";
                query1.Dimensions = "ga:city,ga:date";
                query1.GAStartDate = ("2016-03-15");//DateTime.Now.AddMonths(-1).AddDays(-2).ToString("yyyy-MM-dd");
                query1.GAEndDate = ("2016-03-17");//DateTime.Now.AddDays(-3).ToString("yyyy-MM-dd");
                query1.ExtraParameters = gkey;
                DataFeed dataFeedVisits = service.Query(query1);
                foreach (DataEntry entry in dataFeedVisits.Entries)
                {
                    string st = entry.Title.Text;
                    string ss = entry.Metrics[0].Value;
                    int _intVisists = Int32.Parse(ss);
                    Response.Write("<br/>");
                    Response.Write("Total Visits : " + ss);
                    Response.Write("<br/>");
                }
            }
            catch (Exception ex)
            {
                Response.Write("Error : " + ex);
            }
        }

例外是：

请求执行失败： https : //www.googleapis.com/analytics/v3/data/ga?key=api_key&dimensions= ga:city,ga: date&end-date=2016-03-17&ids= ga: 123456789&metrics= ga: visits ,ga:sessions,ga:pageValue,ga:bounces,ga:bounceRate,ga:pageviews&start-date=2016-03-15

不知何故，它重定向到https://www.google.com/accounts/ClientLogin被谷歌关闭。

Answer 1

1. 客户端登录已于 2015 年 5 月关闭，因此您需要使用 Open 身份验证。
2. 您正在使用 GData 库，它需要将数据作为 XML 返回。
3. 您正在请求 Google Analytics V3 API，它不是 gdata api 并以 JSon 形式返回数据。

解决方案：

安装当前版本的 Google .net 客户端库

PM> 安装包 Google.Apis.Analytics.v3

验证：

string[] scopes = new string[] {AnalyticsService.Scope.AnalyticsReadonly};      // View Google Analytics Data

var clientId = "[Client ID]";      // From https://console.developers.google.com
var clientSecret = "xxx";          // From https://console.developers.google.com
// here is where we Request the user to give us access, or use the Refresh Token that was previously stored in %AppData%
var credential = GoogleWebAuthorizationBroker.AuthorizeAsync(new ClientSecrets { ClientId = clientId,
                                                                                 ClientSecret = clientSecret},
                                                            scopes,
                                                            Environment.UserName,
                                                            CancellationToken.None,
                                                            new FileDataStore("Daimto.GoogleAnalytics.Auth.Store")).Result;

创建分析服务

var service = new AnalyticsService(new BaseClientService.Initializer() { HttpClientInitializer = credential,
                                                                         ApplicationName = "Analytics API Sample",});

请求数据

DataResource.GaResource.GetRequest request = service.Data.Ga.Get("ga:8903098", "2014-01-01", "2014-01-01", "ga:sessions");
request.MaxResults = 1000;
GaData result = request.Execute();
