将 Google Http Batch 与 Google Classroom Api 一起使用

Question

我正在编写一个应用程序（使用 PHP），它将学生添加到 Google 课堂。我正在关注以下文档：

https://developers.google.com/classroom/guides/batch

我正在使用批量请求将多个学生添加到 Google 课堂。但是，批处理请求似乎失败了。我的代码如下：

$service = new Google_Service_Classroom($client);

$service->getClient()->setUseBatch(true);

$batch = $service->createBatch();

$courseId = "123456";
$studentEmails = ["user1@domain.com","user2@domain.com"];

foreach($studentEmails as $email) {
  $student = new Google_Service_Classroom_Student(['userId' => $email]);
  $request = $service->courses_students->create($courseId, $student);
  $requestId = $email;
  $batch->add($request, $requestId);
}

$results = $batch->execute();


foreach($results as $responseId => $student) {
  $studentEmail = substr($responseId, strlen('response-') );
  if ($student instanceof Google_Service_Exception) {
    $e = $student;
    printf("Error adding user '%s' to the course: %s\n", $studentEmail,
      $e->getMessage());
  } else {
    printf("User '%s' was added as a student to the course.\n",
        $student->profile->name->fullName, $courseId);
  }
}

$service->getClient()->setUseBatch(false);

这段代码的输出是：

Error adding user 'user1@domain.com' to the course: Not Found ...

但是，用户和课程都存在于域中。如果我删除批处理代码并一次发出一个请求，学生会成功添加到课堂，这让我相信我在批处理请求中遗漏了一些东西

您可能需要先检查PHP Quickstart，并确保您完成了给定页面其余部分中描述的步骤，以便能够向 Classroom API 发出请求，如批处理请求中的using client libraries 中所述。

成功安装并设置库后，您可以尝试代码示例，该示例演示如何使用 Google API 客户端库发出批处理请求。

$courseId = '123456';
$studentEmails = array('alice@example.edu', 'bob@example.edu');
$service->getClient()->setUseBatch(true);
$batch = $service->createBatch();
foreach($studentEmails as $studentEmail) {
  $student = new Google_Service_Classroom_Student(array(
    'userId' => $studentEmail
  ));
  $request = $service->courses_students->create($courseId, $student);
  $requestId = $studentEmail;
  $batch->add($request, $requestId);
}
$results = $batch->execute();
foreach($results as $responseId => $student) {
  $studentEmail = substr($responseId, strlen('response-') + 1);
  if ($student instanceof Google_Service_Exception) {
    $e = $student;
    printf("Error adding user '%s' to the course: %s\n", $studentEmail,
        $e->getMessage());
  } else {
    printf("User '%s' was added as a student to the course.\n",
        $student->profile->name->fullName, $courseId);
  }
}
$service->getClient()->setUseBatch(false);
