我一直在使用Google的分析报告api v4遇到问题。当我发出请求时，我可以取回数据，但是某些维度和指标值丢失和/或不一致。
例如，如果我想要fullRefferer，它将返回（未设置）。或者当我确实获取值时，我的页面浏览量值可能是1312，而我的会话数可能是26。
我发出请求的代码如下：
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;
}
}
我用于过滤结果的代码在这里：
public static List<AnalyticEntry> Filter(Google.Apis.AnalyticsReporting.v4.Data.GetReportsResponse response)
{
if (response == null) return new List<AnalyticEntry>();
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)
{
foreach (var value in metric.Values)
{
int index = metric.Values.IndexOf(value);
var metricHeader = report.ColumnHeader.MetricHeader.MetricHeaderEntries[index];
switch (metricHeader.Name)
{
case "Sessions":
dto.Sessions = Convert.ToInt32(value);
break;
case "Bounce Rate":
dto.BounceRate = Convert.ToDecimal(value);
break;
case "Page Views":
dto.PageViews = Convert.ToInt32(value);
break;
case "Users":
dto.Users = Convert.ToInt32(value);
break;
}
}
}
foreach (var dimension in row.Dimensions)
{
int index = row.Dimensions.IndexOf(dimension);
var dimensionName = report.ColumnHeader.Dimensions[index];
switch (dimensionName)
{
case "ga:date":
dto.Date = dimension;
break;
case "ga:hour":
dto.Hour = dimension;
break;
case "ga:browser":
dto.Browser = dimension;
break;
case "ga:pagePath":
dto.PagePath = dimension;
break;
case "ga:source":
dto.Source = dimension;
break;
case "ga:fullRefferer":
dto.Referrer = dimension;
break;
}
}
gData.Add(dto);
}
}
return Combine(gData);
}
private static List<AnalyticEntry> Combine(IReadOnlyCollection<GoogleDataDto> gData)
{
List<AnalyticEntry> outputDtos = new List<AnalyticEntry>();
var dates = gData.GroupBy(d => d.Date.Substring(0,6)).Select(d => d.First()).Select(d => d.Date.Substring(0,6)).ToList();
foreach (var date in dates)
{
var entities = gData.Where(d => d.Date.Contains(date)).ToList();
AnalyticEntry dto = new AnalyticEntry
{
Date = date.ToDate(),
PageViews = 0,
Sessions = 0,
Users = 0,
BounceRate = 0
};
foreach (var entity in entities)
{
dto.BounceRate += entity.BounceRate;
dto.PageViews += entity.PageViews;
dto.Users += entity.Users;
dto.Sessions += entity.Sessions;
}
dto.BounceRate = dto.BounceRate / entities.Count();
var dictionaries = entities.GetDictionaries();
var commonBrowsers = dictionaries[0].GetMostCommon();
var commonTimes = dictionaries[1].GetMostCommon();
var commonPages = dictionaries[2].GetMostCommon();
var commonSources = dictionaries[3].GetMostCommon();
var commonReferrers = dictionaries[4].GetMostCommon();
dto.CommonBrowser = commonBrowsers.Key;
dto.CommonBrowserViews = commonBrowsers.Value;
dto.CommonTimeOfDay = commonTimes.Key.ToInt();
dto.CommonTimeOfDayViews = commonTimes.Value;
dto.CommonPage = commonPages.Key;
dto.CommonPageViews = commonPages.Value;
dto.CommonSource = commonSources.Key;
dto.CommonSourceViews = commonSources.Value;
dto.CommonReferrer = commonReferrers.Key;
dto.CommonReferrerViews = commonReferrers.Value;
outputDtos.Add(dto);
}
return outputDtos;
}
我不确定还有什么，请发表评论以获取更多信息：）
答案 0 :(得分：0)
解决了！
最初，我试图根据数组中值的位置查找“度量标准名称”。因此，使用位置可以获取名称并设置值。
问题在于数组可能具有多个相同的值。
例如：
var arr = [1,0,3,1,1];
如果值是1，我试图使用数组中1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找到该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。
这是答案。经过测试并有效
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);
}
}
return gData;
}
