google classroom api student list

Question

Can anyone help me list the students for a specific class using Google Classroom API. I have searched through the API documentation and I can't seem to find out how to do it.

I basically need to do this https://developers.google.com/classroom/reference/rest/v1/courses.students/list

Here is the code I am using. It works with other functions (e.g. $service->students->listCoursesStudents($course_id);):

function G_Course_Roster($course_id) {

    $clientId = '111111111111111111'; 
    $serviceAccountName = '[email protected]';
    $delegatedAdmin = '[email protected]';
    // service account p12 key file:
    $keyFile = '/home/rootfolder/vendor/Google OAuth Login-1111111111.p12';
    $appName = 'name';
    $scopes = array(
        'https://www.googleapis.com/auth/classroom.profile.emails',
        'https://www.googleapis.com/auth/classroom.profile.photos',
        'https://www.googleapis.com/auth/classroom.rosters.readonly'
        );
    $creds = new Google_Auth_AssertionCredentials(
        $serviceAccountName,
        $scopes,
        file_get_contents($keyFile)
    ); 
    $creds->sub = $delegatedAdmin;
    $client = new Google_Client();
    $client->setApplicationName($appName);
    $client->setClientId($clientId);
    $client->setAssertionCredentials($creds);
    $service = new Google_Service_Classroom($client);
    $optParams = array(
        'courseId' => $course_id
    );
    $response = $service->students->listCoursesStudents($course_id);
    return $response;

}

Ok the fix for PHP is $response = $service->courses_students->listCoursesStudents($course_id);

I basically had to guess based on the post above from Mr.Rebot. If someone knows where the PHP documentation is for Google I would appreciate a link

function G_Course_Roster($course_id) {

$clientId = '111111111111111111'; 
$serviceAccountName = '[email protected]';
$delegatedAdmin = '[email protected]';
// service account p12 key file:
$keyFile = '/home/rootfolder/vendor/Google OAuth Login-1111111111.p12';
$appName = 'name';
$scopes = array(
    'https://www.googleapis.com/auth/classroom.profile.emails',
    'https://www.googleapis.com/auth/classroom.profile.photos',
    'https://www.googleapis.com/auth/classroom.rosters.readonly'
    );
$creds = new Google_Auth_AssertionCredentials(
    $serviceAccountName,
    $scopes,
    file_get_contents($keyFile)
); 
$creds->sub = $delegatedAdmin;
$client = new Google_Client();
$client->setApplicationName($appName);
$client->setClientId($clientId);
$client->setAssertionCredentials($creds);
$service = new Google_Service_Classroom($client);
$optParams = array(
    'courseId' => $course_id
);
$response = $service->courses_students->listCoursesStudents($course_id);
return $response;

}

I've tried in the Apps Script and it is working properly. Here is the code snippet:

function listStudent(){

var optionalArgs = {
    pageSize: 10
  };
  var response = Classroom.Courses.list(optionalArgs);
  var courses = response.courses;
  if (courses && courses.length > 0) {
    for (i = 0; i < courses.length; i++) {
      var course = courses[i];
      Logger.log('%s (%s)', course.name, course.id);

      var response2 = Classroom.Courses.Students.list(course.id)
      var students = response2.students;
      if(students && students.length > 0){
      for (j = 0; j < students.length; j++){
           var student = students[j];
           Logger.log('%s (%s)', student.profile, student.userId);
           }
      }


    }
  } else {
    Logger.log('No courses found.');
  }

}

You can test it out, apologies if this is not in PHP code.

Hope this helps.
