谷歌应用程序脚本可以发现一个学生是否在谷歌课堂上迟交作业

Question

对于我正在开发的谷歌应用程序脚本，我需要过滤掉那些迟交的学生提交来降低他们的成绩。

根据Google的文档，我假设这是通过使用classroom.courses.coursework.studentsubmissions.list得到的，但我不知道如何将late参数应用到列表中，以便只得到迟交作业的人。

function onlyLate(){
   var courseId = ID;
   var courseWorkId = ID;
   var la = {"late":"LATE_ONLY"};
   var lat = Classroom.Courses.CourseWork.StudentSubmissions.list(courseId, courseWorkId, la);
   Logger.log(lat);

   for (i = 0; i < lat.length; i++) {
      // lower grades here
   }
} 

Answer 1

function getAllLateSubmissionsByFiltering_(courseId, assignmentId) {
  const options = {
    // late: "LATE_ONLY"
    // or perhaps
    // late: "true"
  };
  const results = [];

  // Collect all results, not just those from the first page.
  do {
    var search = Classroom.Courses.CourseWork.StudentSubmissions.list(courseId, assignmentId, options);
    options.pageToken = search.nextPageToken;
    if (search.studentSubmissions && search.studentSubmissions.length)
      Array.prototype.push.apply(results, search.studentSubmissions);
  } while(options.pageToken);

  // Return only the results that were actually submitted late.
  return results.filter(function (studentSub) {
    studentSub.late === true;
  });
}
