Google 报告 API V4 缺失值

Question

我在使用 Google 的分析报告 api v4 时遇到了问题。当我发出请求时，我可以取回数据，但缺少某些维度和指标值and/or 不一致。

例如，如果我想要 fullRefferer，它将 return（未设置）。或者当我确实获得值时，我的页面浏览量值可能是 1312，而我的会话数可能是 26。

我提出请求的代码如下：

public GetReportsResponse Get(string viewId, DateTime startDate, DateTime endDate, string nextPageToken = null)
    {
        try
        {
            var credential = GetCredential();
            using (var svc = new AnalyticsReportingService(
                new BaseClientService.Initializer
                {
                    HttpClientInitializer = credential
                }))
            {
                var mets = new List<Metric>
                {
                    new Metric
                    {
                        Alias = "Users",
                        Expression = "ga:users"
                    },
                    new Metric
                    {
                        Alias = "Bounce Rate",
                        Expression = "ga:bounceRate"
                    },
                    new Metric
                    {
                        Alias = "Page Views",
                        Expression = "ga:pageViews"
                    },
                    new Metric()
                    {
                        Alias = "Sessions",
                        Expression = "ga:sessions"
                    }
                };

                var dims = new List<Dimension>
                {
                    new Dimension { Name = "ga:date" },
                    new Dimension { Name = "ga:hour" },
                    new Dimension { Name = "ga:browser" },
                    new Dimension { Name = "ga:pagePath" },
                    new Dimension { Name = "ga:fullReferrer"}
                };

                var dateRange = new DateRange
                {
                    StartDate = startDate.ToFormattedString(),
                    EndDate = endDate.ToFormattedString()
                };

                var reportRequest = new ReportRequest
                {
                    DateRanges = new List<DateRange> { dateRange },
                    Dimensions = dims,
                    Metrics = mets,
                    ViewId = viewId,
                    PageToken = nextPageToken
                };
                var getReportsRequest = new GetReportsRequest
                {
                    ReportRequests = new List<ReportRequest> { reportRequest },
                };
                var batchRequest = svc.Reports.BatchGet(getReportsRequest);
                var response = batchRequest.Execute();

                return response;
            }
        }
        catch (Exception e)
        {
            return null;
        }
    }

我过滤结果的代码在这里：

Answer 1

已解决！

最初我试图根据数组中值的位置找到 'metric name'。所以使用位置我会得到名称并设置值。

问题是数组可能有多个相同的值。

例如：

var arr = [1,0,3,1,1];

如果值为 1，我试图使用 1 在数组中的位置来获取名称。因此，如果数组中 1 的索引为 0，我将通过使用该索引并在另一个数组中查找名称来找到它的名称。

例如：

var names = ['a','b','c'];
var values = [1,2,1];

var value = 1;
var index = values.indexOf(value); // which would be 0  

SetProperty(
    propertyName:names[index], // being a
    value: value);

尽管很难解释，但由于数组中有多个值等于同一事物，所以我多次设置了相同的值。

答案在这里。已测试并有效

public List<GoogleDataDto> Filter(GetReportsResponse response)
    {
        if (response == null) return null;

        List<GoogleDataDto> gData = new List<GoogleDataDto>();
        foreach (var report in response.Reports)
        {
            foreach (var row in report.Data.Rows)
            {
                GoogleDataDto dto = new GoogleDataDto();

                foreach (var metric in row.Metrics)
                {
                    int index = 0; // Index counter, used to get the metric name
                    foreach (var value in metric.Values)
                    {
                        var metricHeader = report.ColumnHeader.MetricHeader.MetricHeaderEntries[index];

                        //Sets property value based on the metric name
                        dto.SetMetricValue(metricHeader.Name, value);
                        index++;
                    }
                }

                int dIndex = 0; // Used to get dimension name
                foreach (var dimension in row.Dimensions)
                {
                    var dimensionName = report.ColumnHeader.Dimensions[dIndex];

                    //Sets property value based on dimension name
                    dto.SetDimensionValue(dimensionName, dimension);

                    dIndex++;
                }

                // Will only add the dto to the list if its not a duplicate
                if (!gData.IsDuplicate(dto))
                    gData.Add(dto);
            }
