我需要访问Analytics Reporting API V4。我按照下面的文档来完成这项工作。
https://developers.google.com/analytics/devguides/reporting/core/v4/quickstart/service-php
但是从一开始我就得到了这个错误
致命错误：未捕获的异常'Google_Service_Exception' 消息'in C：\ wamp64 \ WWW \ ga_test \供应商\谷歌\ apiclient的\ src \谷歌\ HTTP \ REST.php 在第118行
Google_Service_Exception：{“error”：{“code”：401，“message”：“The 请求没有有效的身份验证凭据。“，”错误“：[ {“message”：“请求没有有效的身份验证 凭证。“，”“域名”：“全球”，“原因”：“未授权”}]， “status”：“UNAUTHENTICATED”}} in C：\ wamp64 \ WWW \ ga_test \供应商\谷歌\ apiclient的\ src \谷歌\ HTTP \ REST.php 在第118行调用堆栈
如何解决此问题。我按照文档和确切的PHP代码遵循所有步骤。
<?php
// Load the Google API PHP Client Library.
require_once __DIR__ . '/vendor/autoload.php';
$analytics = initializeAnalytics();
$response = getReport($analytics);
printResults($response);
function initializeAnalytics()
{
// Creates and returns the Analytics Reporting service object.
// Use the developers console and download your service account
// credentials in JSON format. Place them in this directory or
// change the key file location if necessary.

// Create and configure a new client object.
$client = new Google_Client();
$client->setApplicationName("Hello Analytics Reporting");
$client->setAuthConfig($KEY_FILE_LOCATION);
$client->setScopes(['https://www.googleapis.com/auth/analytics.readonly']);
$analytics = new Google_Service_AnalyticsReporting($client);
return $analytics;
}
function getReport($analytics) {
// Replace with your view ID, for example XXXX.
$VIEW_ID = "xxxxxxx";
// Create the DateRange object.
$dateRange = new Google_Service_AnalyticsReporting_DateRange();

$body = new Google_Service_AnalyticsReporting_GetReportsRequest();
$body->setReportRequests( array( $request) );
return $analytics->reports->batchGet( $body );
}
function printResults($reports) {
for ( $reportIndex = 0; $reportIndex < count( $reports ); $reportIndex++ ) {
$report = $reports[ $reportIndex ];
$header = $report->getColumnHeader();
$dimensionHeaders = $header->getDimensions();
$metricHeaders = $header->getMetricHeader()->getMetricHeaderEntries();
$rows = $report->getData()->getRows();
for ( $rowIndex = 0; $rowIndex < count($rows); $rowIndex++) {
$row = $rows[ $rowIndex ];
$dimensions = $row->getDimensions();
$metrics = $row->getMetrics();
for ($i = 0; $i < count($dimensionHeaders) && $i < count($dimensions); $i++) {
print($dimensionHeaders[$i] . ": " . $dimensions[$i] . "\n");
}
for ($j = 0; $j < count( $metricHeaders ) && $j < count( $metrics ); $j++) {
$entry = $metricHeaders[$j];
$values = $metrics[$j];
print("Metric type: " . $entry->getType() . "\n" );
for ( $valueIndex = 0; $valueIndex < count( $values->getValues() ); $valueIndex++ ) {
$value = $values->getValues()[ $valueIndex ];
print($entry->getName() . ": " . $value . "\n");
}
}
}
}
}
请帮助解决此问题。当var_dump $ analytics得到这个结果时，
