通过API提取Google分析多通道漏斗数据

Question

我试图从中提取多通道漏斗报告，并得到以下错误：

无效值'mcf:source‘。值必须匹配以下正则表达式：'(ga:.+)?'

下面是我使用的代码，当维度和度量来自ga：.时，它工作得很好。家人，但出于某种原因，它不让我拉mcf:报告。

$analytics = new Google_Service_Analytics($client);
$analytics_id   = 'ga:XXXXXXXX';
$lastWeek       = date('Y-m-d', strtotime('-26 day', time()));
$today          = date('Y-m-d', strtotime('-26 day', time()));

try {
    $optParams = array();
    $optParams['dimensions'] = "mcf:source";
    #$optParams['sort'] = "";
    $optParams['max-results'] = "10000";
    $metrics = 'mcf:totalConversions';
    $results = $analytics->data_ga->get($analytics_id,
                       $lastWeek,
                       $today,$metrics,$optParams);

    $rows = $results->getRows();
    foreach ($results->columnHeaders as $header) {
        $headerName = ucwords(preg_replace('/(\w+)([A-Z])/U', '\\1 \\2', str_replace('ga:', '', $header->name)));
        printf('%s', $headerName);
        print ',';
    }

    print "\n";

    foreach ($results->rows as $row) {
        foreach ($row as $cell) {
            printf('%s', $cell);
            print ',';
        }
        print "\n";
    }
}

从我的头看，这是因为您使用的是$analytics->data_ga->get()而不是$analytics->data_mcf->get() (多通道数据有自己的API)。
