(403)请求的身份验证范围不足 - OAuth 范围为 Google 课堂 API

我是新来的，我不是程序员，那么我需要你的帮助。

我正在测试说明 管理教师和学生 在这里找到：https://developers.google.com/classroom/guides/manage-users

我尝试使用身份验证和作用域，就像它们在 PHP 快速入门中所做的那样：https://developers.google.com/classroom/quickstart/php

我成功运行了快速入门.php示例，然后这意味着作曲家已成功安装，但由于身份验证范围不足，我无法运行代码来//在课程中注册学生。

错误信息：

致命错误：未捕获的异常"Google_Service_Exception" 消息"调用开机自检时出错 h_ttps：//classroom.googleapis.com/v1/courses/559522327/students？enrollmentCode=2j1l21l： （403） 请求的身份验证范围不足。 C：''ProgramData''ComposerSetup''bin''vendor''google''apiclient''src''Google''Http''REST.php：110 堆栈跟踪：#0 C：''ProgramData''ComposerSetup''bin''vendor''google''apiclient''src''Google''Http''REST.php（62）： Google_Http_REST：:d ecodeHttpResponse（Object（Google_Http_Request）， 对象（Google_Client）） #1 [内部函数]： Google_Http_REST：:d oExecute（Object（Google_Client）， 对象（Google_Http_Request）） #2 C：''ProgramData''ComposerSetup''bin''vendor''google''apiclient''src''Google''Task''Runner.php（174）： call_user_func_array（阵列，阵列）#3 C：''ProgramData''ComposerSetup''bin''vendor''google''apiclient''src''Google''Http''REST.php（46）： Google_Task_Runner->run（） #4 C：''ProgramData''ComposerSetup''bin''vendor''google''apiclient''src''Google''Client.php（593）： Google_Http_REST：：execute（Object（Google_Client）， 对象（Google_Http_Request）） #5 C：''Pr inC：''ProgramData''ComposerSetup''bin''vendor''google''apiclient''src''Google''Http''REST.php 在 110 行

尝试调整示例代码：

<?php

  if (empty($homeDirectory)) {

$client = getClient();
$service = new Google_Service_Classroom($client);

//Enroll the student in the course given below
$courseId = '559522327';
$enrollmentCode = '2j1l21l';
$student = new Google_Service_Classroom_Student(array(
  'userId' => 'me',
));
$params = array(
  'enrollmentCode' => $enrollmentCode
);
try {
  $student = $service->courses_students->create($courseId, $student, $params);
  printf("User '%s' was enrolled  as a student in the course with ID '%s'.'n",
      $student->profile->name->fullName, $courseId);
} catch (Google_Service_Exception $e) {
  if ($e->getCode() == 409) {
    print "You are already a member of this course.'n";
  } else {
    throw $e;
  }
}
?>

这与作用域和Google_Service_Classroom类有关吗？

如果你能帮助我，我将不胜感激！
