如何调用Google Analytics（分析）多渠道路径API请求以获取数据

Question

在请求多渠道路径之前，我正在使用Core Reporting API，并且运行良好，但是现在我需要多渠道路径数据，并且已经阅读了Google提供的MCF完整指南。

但是我不确定该怎么做。下面，我粘贴我以前的核心报告api代码，该代码运行良好。现在，我应该为多渠道路径api请求做什么。

我必须使用另一个php库或另一个函数，还是应该使用与核心报告api相同的函数。

将参数传递给自定义创建的函数以调用库函数

$arrMetrics = ['ga:users' => 'Users', 'ga:adClicks' => 'Clicks', 'ga:adCost' => 'Cost', 'ga:CPC' => 'CPC'];
        $duration = $_POST['chart_duration'];
        $arrParam = getDurationFromText($_POST['chart_duration']);

        $arrConfig = [];
        $arrConfig['StartDate'] = $arrParam['StartDate'];
        $arrConfig['EndDate'] = $arrParam['EndDate'];

        $analyticsData = $ga->getReport($site,$arrMetrics,$arrConfig);

        if($analyticsData['is_success'])
        {
            $arrProccessData = printResults($analyticsData['data']);

            $arrData = [];
            $arrData['Clicks']['data'] = $arrProccessData[0][0]['metrics']['Clicks'];
            $arrData['Cost']['data'] = round($arrProccessData[0][0]['metrics']['Cost'], 2);
            $arrData['CPC']['data'] = round($arrProccessData[0][0]['metrics']['CPC'], 2);

            $arrTotal = [];
            foreach($arrData as $key => $data)
            {

                $arrTotal[$key] = $data['data'];
            }

            $arrResult['is_success'] = true;
            $arrResult['total'] = $arrTotal;
        }
        else
        {
            $arrResult['is_success'] = false;
            $arrResult['message'] = $analyticsData['error']->error->message;
        }

这是getReport函数

function getReport($objSite,$arrMetrics,$arrConfig) {

        $this->client->setAccessToken($objSite->accessToken);
        $analytics = new Google_Service_AnalyticsReporting($this->client);
          // Replace with your view ID, for example XXXX.
        $VIEW_ID = $objSite->project_id;

        $request = new Google_Service_AnalyticsReporting_ReportRequest();
        $request->setViewId($VIEW_ID);

        // Create the Metrics object.
        $setMetrics=[];
        foreach($arrMetrics as $key => $alias)
        {
            $ga_metrics = new Google_Service_AnalyticsReporting_Metric();
            $ga_metrics->setExpression($key);
            $ga_metrics->setAlias($alias);
            $setMetrics[] = $ga_metrics;
        }
        $request->setMetrics($setMetrics);

        //Create the Dimensions object.
        if(!empty($arrConfig['dimensions']))
        {
            $setDimensions=[];
            foreach($arrConfig['dimensions'] as $dimensions)
            {
                $objDimensions = new Google_Service_AnalyticsReporting_Dimension();
                $objDimensions->setName($dimensions);
                $setDimensions[] = $objDimensions;
            }
            $request->setDimensions($setDimensions);
        }
        if(!empty($arrConfig['filter']))
        {
            $setFilter=[];
            foreach($arrConfig['filter'] as $filter)
            {
                $dimensionFilter = new Google_Service_AnalyticsReporting_DimensionFilter();
                $dimensionFilter->setDimensionName($filter['dimension']);
                $dimensionFilter->setOperator($filter['operator']);
                $dimensionFilter->setExpressions([$filter['value']]);
                $setFilter[] = $dimensionFilter;
            }
            // Create the DimensionFilterClauses
            $dimensionFilterClause = new Google_Service_AnalyticsReporting_DimensionFilterClause();
            $dimensionFilterClause->setFilters($setFilter);
            $request->setDimensionFilterClauses(array($dimensionFilterClause));
        }
        if(!empty($arrConfig['StartDate']))
        {
          // Create the DateRange object.
            $dateRange = new Google_Service_AnalyticsReporting_DateRange();
            $dateRange->setStartDate($arrConfig['StartDate']);
            $dateRange->setEndDate($arrConfig['EndDate']);
            $request->setDateRanges($dateRange);
        }

        if(!empty($arrConfig['sort']))
        {
            $orderby =new Google_Service_AnalyticsReporting_OrderBy();
            $orderby->setFieldName($arrConfig['sort']['field']);
            $orderby->setSortOrder($arrConfig['sort']['order']);
            $request->setOrderBys($orderby);
        }
        if(!empty($arrConfig['page_size']))
        {
            $request->setPageSize($arrConfig['page_size']);
        }
        $return = [];
        try{
            $body = new Google_Service_AnalyticsReporting_GetReportsRequest();
            $body->setReportRequests( array( $request) );
            $return['data'] = $analytics->reports->batchGet( $body );
            $return['is_success'] = true;
        }
        catch(exception $e)
        {
            $return['is_success'] = false;
            $return['error'] = json_decode($e->getMessage());
        }
        return $return;
    }

在阅读了一些指南并提供了帮助之后，我才知道必须调用不同的类和方法，但仍然感到困惑。
