google-analytics - 错误 : Analytics Reporting API V4 has not been used in project

Question

我正在尝试从 JAVA 代码访问我的 Analytics(分析)数据。但是当下面的代码运行时，

package com.test.googleapi;

import java.io.File;
import java.io.FileInputStream;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collections;

import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;
import com.google.api.client.googleapis.javanet.GoogleNetHttpTransport;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.json.JsonFactory;
import com.google.api.client.json.jackson2.JacksonFactory;
import com.google.api.services.analyticsreporting.v4.AnalyticsReporting;
import com.google.api.services.analyticsreporting.v4.model.DateRange;
import com.google.api.services.analyticsreporting.v4.model.Dimension;
import com.google.api.services.analyticsreporting.v4.model.GetReportsRequest;
import com.google.api.services.analyticsreporting.v4.model.GetReportsResponse;
import com.google.api.services.analyticsreporting.v4.model.Metric;
import com.google.api.services.analyticsreporting.v4.model.ReportRequest;

public class AnalyticsApiTest {
    public static void main(String[] args) throws Exception {
        GoogleCredential credential = GoogleCredential
                .fromStream(new FileInputStream(new File("assets/client-secrets/service-account-key.json")))
                .createScoped(Collections.singleton("https://www.googleapis.com/auth/analytics.readonly"));
        HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
        JsonFactory jsonFactory = JacksonFactory.getDefaultInstance();
        AnalyticsReporting analyticsReporting = new AnalyticsReporting.Builder(httpTransport, jsonFactory, credential)
                .setApplicationName("Test")
                .build();

        DateRange dateRange = new DateRange();
        dateRange.setStartDate("2015-06-15");
        dateRange.setEndDate("2015-06-30");

        // Create the Metrics object.
        Metric sessions = new Metric()
            .setExpression("ga:sessions")
            .setAlias("sessions");

        //Create the Dimensions object.
        Dimension browser = new Dimension()
            .setName("ga:browser");

        // Create the ReportRequest object.
        ReportRequest request = new ReportRequest()
            .setViewId("XXXX")
            .setDateRanges(Arrays.asList(dateRange))
            .setDimensions(Arrays.asList(browser))
            .setMetrics(Arrays.asList(sessions));

        ArrayList<ReportRequest> requests = new ArrayList<ReportRequest>();
        requests.add(request);

        // Create the GetReportsRequest object.
        GetReportsRequest getReport = new GetReportsRequest()
            .setReportRequests(requests);

        // Call the batchGet method.
        GetReportsResponse response = analyticsReporting.reports().batchGet(getReport).execute();

    }
}

我收到以下错误:

我已经在 analytics-test-1279 项目中设置了服务帐户 key 。 Analytics API 也已启用。

我无法弄清楚这里到底是什么问题。

如错误消息中所述，您需要启用 Analytics Reporting API .他们在错误中轻松地为您提供了指向同一页面的直接链接。

从您的屏幕截图中，您已经启用了 Analytics API .其中包含 Management API V3和旧Core Reporting API V3 .

随着 Analytics Reporting API V4 的发布您需要启用全新的 API。好消息是authorize仍然使用相同的范围，因此您的用户无需重新授权您的应用程序。
