Question

我是新来的，我不是程序员，我需要你的帮助。

我正在测试说明管理在这里找到的老师和学生： https://developers.google.com/classroom/guides/manage-users

我尝试在PHP QuickStart中使用身份验证和范围： https://developers.google.com/classroom/quickstart/php

我成功运行了quickstart.php示例，这意味着该作曲家已成功安装，但我无法运行代码//由于认证范围不足，在课程中注册学生。

错误讯息：

致命错误：未捕获的异常＆＃39; Google_Service_Exception＆＃39;同消息＆＃39;调用POST时出错 h_ttps：//classroom.googleapis.com/v1/courses/559522327/students enrollmentCode = 2j1l21l：（403）请求的认证范围不足。＆＃39;在 C：\ ProgramData \ ComposerSetup \ BIN \供应商\谷歌\ apiclient的\ src \谷歌\ HTTP \ REST.php：110 堆栈跟踪：＃0 C：\ ProgramData \ ComposerSetup \ BIN \供应商\谷歌\ apiclient的\ src \谷歌\ HTTP \ REST.php（62）： Google_Http_REST :: decodeHttpResponse（对象（Google_Http_Request）对象（Google_Client））＃1 [内部函数]： Google_Http_REST :: doExecute（对象（Google_Client）对象（Google_Http_Request））＃2 C：\ ProgramData \ ComposerSetup \ BIN \供应商\谷歌\ apiclient的\ src \谷歌\工作\ Runner.php（174）： call_user_func_array（Array，Array）＃3 C：\ ProgramData \ ComposerSetup \ BIN \厂商\谷歌\ apiclient \ SRC \谷歌\ HTTP \ REST.php（46）： Google_Task_Runner-＆gt; run（）＃4 C：\ ProgramData \ ComposerSetup \ BIN \供应商\谷歌\ apiclient的\ src \谷歌\ Client.php（593）： Google_Http_REST ::执行（对象（Google_Client）对象（Google_Http_Request））＃5 C：\ Pr INC：\ ProgramData \ ComposerSetup \ BIN \供应商\谷歌\ apiclient的\ src \谷歌\ HTTP \ REST.php 在线110

尝试调整示例代码：

<?php

require __DIR__ . '/vendor/autoload.php';

define('APPLICATION_NAME', 'Classroom API PHP Quickstart');
define('CREDENTIALS_PATH', '~/.credentials/classroom-php-quickstart.json');
define('CLIENT_SECRET_PATH', __DIR__ . '/client_secret.json');
define('SCOPES', implode(' ', array(
  Google_Service_Classroom::CLASSROOM_ROSTERS) 
));

if (php_sapi_name() != 'cli') {
 //  throw new Exception('This application must be run on the command line.');
}

/**
 * Returns an authorized API client.
 * @return Google_Client the authorized client object
 */
function getClient() {
  $client = new Google_Client();
  $client->setApplicationName(APPLICATION_NAME);
  $client->setScopes(SCOPES);
  $client->setAuthConfigFile(CLIENT_SECRET_PATH);
  $client->setAccessType('offline');

  // Load previously authorized credentials from a file.
  $credentialsPath = expandHomeDirectory(CREDENTIALS_PATH);
  if (file_exists($credentialsPath)) {
    $accessToken = file_get_contents($credentialsPath);
  } else {
    // Request authorization from the user.
   $authUrl = $client->createAuthUrl();
    printf("Open the following link in your browser:\n%s\n", $authUrl);
    print 'Enter verification code: ';
    $authCode = trim(fgets(STDIN));

    // Exchange authorization code for an access token.
    $accessToken = $client->authenticate($authCode);

    // Store the credentials to disk.
    if(!file_exists(dirname($credentialsPath))) {
      mkdir(dirname($credentialsPath), 0700, true);
    }
    file_put_contents($credentialsPath, $accessToken);
    printf("Credentials saved to %s\n", $credentialsPath);
  }
  $client->setAccessToken($accessToken);

  // Refresh the token if it's expired.
  if ($client->isAccessTokenExpired()) {
    $client->refreshToken($client->getRefreshToken());
    file_put_contents($credentialsPath, $client->getAccessToken());
  }
  return $client;
}

/**
 * Expands the home directory alias '~' to the full path.
 * @param string $path the path to expand.
 * @return string the expanded path.
 */
function expandHomeDirectory($path) {
  $homeDirectory = getenv('HOME');
  if (empty($homeDirectory)) {
    $homeDirectory = getenv("HOMEDRIVE") . getenv("HOMEPATH");
  }
  return str_replace('~', realpath($homeDirectory), $path);
}

// Get the API client and construct the service object.
$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;
  }
}

?>

它与范围和Google_Service_Classroom类有关吗？

如果你能帮助我，我将非常感激！

According to the docs，需要以下范围之一：

https://www.googleapis.com/auth/classroom.rosters
https://www.googleapis.com/auth/classroom.profile.emails
https://www.googleapis.com/auth/classroom.profile.photos
