Question

我正在使用Google客户端库来使用Google Analytics Reporting API第4版从Google Analytics获取数据。问题是它不接受我的正则表达式。我已经确认正则表达式适用于Google的查询资源管理器。当我尝试将它与Google_Service_AnalyticsReporting_DimensionFilter（）类一起使用时，它无效。输出显示Totals等于零意味着没有返回任何记录。请看下面的代码：

function getReport($analytics)
{

    // Replace with your view ID, for example XXXX.
    $VIEW_ID = $this->viewId;

    // Create the DateRange object.
    $dateRange = new Google_Service_AnalyticsReporting_DateRange();
    $dateRange->setStartDate($this->startDate);
    $dateRange->setEndDate($this->endDate);

    // Create the Metrics object.
    $sessions = new Google_Service_AnalyticsReporting_Metric();
    $sessions->setExpression($this->metrics);
    $sessions->setAlias($this->metricAlias);

    //Create the Dimensions object.
    $pagePath = new Google_Service_AnalyticsReporting_Dimension();
    $pagePath->setName("ga:pagePath");

    // Create Dimension Filter 1, Must use: =~
    $dimensionFilter1 = new Google_Service_AnalyticsReporting_DimensionFilter();
    $dimensionFilter1->setDimensionName("ga:pagePath");
    $dimensionFilter1->setOperator('REGEXP');
    $dimensionFilter1->setExpressions('27-of-the-most-beautiful-small-towns-to-visit-in-europe');
    $dimensionFilter1->setNot(FALSE);

    // Create Dimension Filter 2, Must use: !~
    $dimensionFilter2 = new Google_Service_AnalyticsReporting_DimensionFilter();
    $dimensionFilter2->setDimensionName("ga:pagePath");
    $dimensionFilter2->setOperator('REGEXP');
    $dimensionFilter2->setExpressions('\/.*?\/[0-9]+');
    $dimensionFilter2->setNot(TRUE);

    // Create Dimension Filter 3, Must use !~
    $dimensionFilter3 = new Google_Service_AnalyticsReporting_DimensionFilter();
    $dimensionFilter3->setDimensionName("ga:pagePath");
    $dimensionFilter3->setOperator('REGEXP');
    $dimensionFilter3->setExpressions('\/.*?\/images/images');
    $dimensionFilter3->setNot(TRUE);

    // Create the DimensionFilterClauses
    $dimensionFilterClause = new Google_Service_AnalyticsReporting_DimensionFilterClause();
    $dimensionFilterClause->setFilters([$dimensionFilter1, $dimensionFilter2, $dimensionFilter3]);

    // Create the ReportRequest object.
    $request = new Google_Service_AnalyticsReporting_ReportRequest();
    $request->setViewId($VIEW_ID);
    $request->setDateRanges($dateRange);
    $request->setMetrics([$sessions]);
    $request->setDimensions([$pagePath]);
    $request->setDimensionFilterClauses([$dimensionFilterClause]);

    $request->setIncludeEmptyRows(false);

    $body = new Google_Service_AnalyticsReporting_GetReportsRequest();
    $body->setReportRequests([$request]);

    return $analytics->reports->batchGet($body);
}

这段代码不正确吗？

 // Create Dimension Filter 1.
    $dimensionFilter = new Google_Service_AnalyticsReporting_DimensionFilter();
    $dimensionFilter->setDimensionName("ga:pagePath");
    $dimensionFilter->setOperator('REGEXP');
    $dimensionFilter->setExpressions('ga:PagePath !~ \/.*?\/[0-9]+');

Answer 1

是。代码中有错误。您不应在ga:pagePath方法中包含维度名称，即setExpression。

我假设您尝试在过滤器中添加Does not match Regular Expression运算符。

所以你的代码应该是这样的：

$dimensionFilter = new Google_Service_AnalyticsReporting_DimensionFilter();
$dimensionFilter->setDimensionName("ga:pagePath");
$dimensionFilter->setOperator('REGEXP');
$dimensionFilter->setExpressions('\/.*?\/[0-9]+');
$dimensionFilter->setNot(TRUE);

看看它是否有效。
