Người dùng của bạn có đang sử dụng Lớp học với Google Meet không? Hãy tham khảo bài viết hướng dẫn nhanh về Apps Script để biết cách điểm danh học viên trong các khóa học của Google Meet.

Quản lý khóa học

Tài nguyên khoá học đại diện cho một lớp (chẳng hạn như "Math 127)" cũng như giáo viên, danh sách học viên và siêu dữ liệu đã chỉ định cho lớp.

Mỗi khóa học được xác định bằng một mã nhận dạng duy nhất do máy chủ chỉ định. Ngoài ra, tên có thể được liên kết với một khóa học và được sử dụng thay cho mã nhận dạng duy nhất. Mỗi tên, được gọi là Bí danh, tồn tại trong một không gian tên hạn chế những người có thể tạo và xem tên.

Hai vùng chứa tên được hỗ trợ:

  • Miền: Không gian tên miền hữu ích cho việc tạo các bí danh mà tất cả người dùng cần quyền truy cập, nhưng không dành riêng cho bất kỳ chương trình nào. Ví dụ: bạn nên tạo các trang thông tin thay thế cho một khoá học, chẳng hạn như MATH 127 và COMSCI 127 trong vùng chứa tên miền. Chỉ quản trị viên miền mới có thể tạo bí danh trong vùng chứa tên miền, nhưng tất cả người dùng trong miền đều có thể nhìn thấy bí danh.
  • Dự án dành cho nhà phát triển: Không gian tên của dự án dành cho nhà phát triển sẽ hữu ích cho việc quản lý bí danh dành riêng cho ứng dụng. Ví dụ: Một ứng dụng sử dụng giá trị nhận dạng thay thế cho các khoá học có thể tạo các bí danh để liên kết giá trị nhận dạng đó với các khoá học của Lớp học. Các bí danh được tạo trong không gian tên này được liên kết với một dự án Bảng điều khiển API của Google cụ thể. Bất kỳ người dùng ứng dụng nào cũng có thể tạo và xem các bí danh trong không gian tên của dự án nhà phát triển ứng dụng đó.

Tạo khóa học

Bạn có thể thêm một khoá học bằng cách sử dụng phương thức courses.create(), như trong ví dụ sau:

Khi tạo khoá học, bạn có thể tuỳ ý thêm siêu dữ liệu như nội dung mô tả, thời gian hoặc vị trí của khoá học.

Để tạo một khóa học, người dùng phải đưa ra yêu cầu phải có quyền thích hợp trong hồ sơ người dùng của mình.

Các khoá học được tạo bằng courseState đặt thành PROVISIONED theo mặc định; tuy nhiên, bạn có thể ghi đè các lớp này thành ACTIVE. Nếu khoá được tạo ở trạng thái PROVISIONED, thì giáo viên được xác định trong ownerId phải chấp nhận lớp trong giao diện người dùng của Lớp học hoặc khoá học phải được cập nhật thông qua API để thay đổi courseState thành ACTIVE và cung cấp cho học viên của lớp đó.

Truy xuất thông tin chi tiết về khoá học

Bạn có thể truy xuất siêu dữ liệu về một khoá học bằng phương thức courses.get() như trong mẫu sau:

Cập nhật thông tin khóa học

Bạn có thể cập nhật một số siêu dữ liệu khoá học sau khi tạo khoá học. Bạn có thể cập nhật các trường sau đây bất cứ lúc nào sau khi tạo khoá học:

  • name
  • section
  • descriptionHeading
  • description
  • room
  • courseState
  • ownerId

Để cập nhật tất cả các trường trong một khoá học, hãy sử dụng phương thức courses.update(), như trong ví dụ sau:
