Google Analytics API 和 .Net

使用Google Analytics API 和 .Net 进行数据分析

csharp
using Google.Apis.AnalyticsReporting;
using Google.Apis.Auth.OAuth2;
using Google.Apis.Services;
using Google.Apis.Util.Store;
using System;
using System.Collections.Generic;
using System.IO;
using System.Threading;

csharp
string[] scopes = { AnalyticsReportingService.Scope.AnalyticsReadonly };
string applicationName = "YOUR_APPLICATION_NAME";
UserCredential credential;
using (var stream = new FileStream("client_secret.json", FileMode.Open, FileAccess.Read))
{
    string credPath = "token.json";
    credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
        GoogleClientSecrets.Load(stream).Secrets,
        scopes,
        "user",
        CancellationToken.None,
        new FileDataStore(credPath, true)).Result;
}

csharp
var analyticsService = new AnalyticsReportingService(new BaseClientService.Initializer()
{
    HttpClientInitializer = credential,
    ApplicationName = applicationName
});
var dateRange = new DateRange
{
    StartDate = DateTime.Today.AddDays(-7).ToString("yyyy-MM-dd"),

    DateRanges = new List { dateRange },
    Metrics = new List { sessions }
};
var getReportsRequest = new GetReportsRequest
{

};
var batchRequest = analyticsService.Reports.BatchGet(getReportsRequest);
var response = batchRequest.Execute();

csharp
foreach (var report in response.Reports)

    foreach (var row in report.Data.Rows)
    {
        var dateRangeValues = row.Metrics.First().Values;
        var sessions = dateRangeValues.FirstOrDefault();
