我正在尝试使用google analytics报告api v4，我按照此链接中的说法执行了每一步：reporting api v4
现在我收到了这个错误：
Fatal error: Uncaught exception 'Google_Service_Exception' with message '{ "error": "invalid_grant", "error_description": "Invalid JWT Signature." } ' in C:\xampp\htdocs\gaapi\vendor\google\apiclient\src\Google\Http\REST.php:118 Stack trace: #0 C:\xampp\htdocs\gaapi\vendor\google\apiclient\src\Google\Http\REST.php(94): Google_Http_REST::decodeHttpResponse(Object(GuzzleHttp\Psr7\Response), Object(GuzzleHttp\Psr7\Request), 'Google_Service_...') #1 [internal function]: Google_Http_REST::doExecute(Object(GuzzleHttp\Client), Object(GuzzleHttp\Psr7\Request), 'Google_Service_...') #2 C:\xampp\htdocs\gaapi\vendor\google\apiclient\src\Google\Task\Runner.php(181): call_user_func_array(Array, Array) #3 C:\xampp\htdocs\gaapi\vendor\google\apiclient\src\Google\Http\REST.php(58): Google_Task_Runner->run() #4 C:\xampp\htdocs\gaapi\vendor\google\apiclient\src\Google\Client.php(779): Google_Http_REST::execute(Object(GuzzleHttp\Client), Object(GuzzleHttp\Psr7\Request), 'Google_Service_...', Array) #5 C:\xampp\htdocs\gaapi\vendor\google\a in C:\xampp\htdocs\gaapi\vendor\google\apiclient\src\Google\Http\REST.php on line 118
这是rest.php，我收到了这个错误：

如果您需要我为您上传其他文件，请告诉我。
答案 0 :(得分：0)
我应该在try catch块中放入正在异常的部分代码。它工作正常。因此，如果您想使用GA报告API版本4，您应该添加此try catch，其他所有内容都必须与文档完全相同，并且您已完成。
