使用 oauth2.0 java 获取谷歌访问令牌的简单示例

Question

我想使用谷歌访问令牌获取谷歌分析数据，但我没有找到任何示例，我收到“线程中的异常”

"main" java.net.SocketException: 连接重置"

错误，下面是代码：-

import java.io.File;
import java.io.FileInputStream;

import java.util.Arrays;
import java.util.Collections;

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("d:\\clientsecretnew.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("testing_analytics")
                .build();

        DateRange dateRange = new DateRange();
        dateRange.setStartDate("2017-06-11");
        dateRange.setEndDate("2017-06-13");

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

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

        // Create the ReportRequest object.
        ReportRequest request = new ReportRequest()
            .setViewId("ga:152411###")
            .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();


    }
}

谁能告诉这其中有什么问题？？

我认为您应该尝试关注Googles tutorials。这是我使用的代码ga:pageview 不是一个有效的指标，它的ga:pageviews
