Kelola Topik

Resource topik mewakili sekelompok item streaming yang dikategorikan berdasarkan kemiripan, seperti minggu yang ditetapkan atau mata pelajaran kursus.

Setiap topik diidentifikasi dengan ID unik yang ditetapkan oleh server. ID kursus yang terkait dengan ID ini adalah ID kursus tempat topik berada, nama topik sebenarnya yang ditampilkan di UI Classroom, serta tanggal dan waktu pembaruan terakhir.

Membuat topik

Anda dapat membuat topik baru dalam kursus menggunakan metode topics.create(), seperti yang ditunjukkan dalam contoh berikut:

Java

classroom/snippets/src/main/java/CreateTopic.java
Topic topic = null;
try {
  // Create the new Topic.
  Topic content = new Topic().setName("Semester 1");
  topic = service.courses().topics().create(courseId, content).execute();
  System.out.println("Topic id: " + topic.getTopicId() + "\n" + "Course id: " + courseId);
} catch (GoogleJsonResponseException e) {
  // TODO (developer) - handle error appropriately
  GoogleJsonError error = e.getDetails();
  if (error.getCode() == 404) {
    System.out.printf("The courseId does not exist: %s.\n", courseId);
  } else {
    throw e;
  }
} catch (Exception e) {
  throw e;
}
return topic;

Python

topic = {
    "name": 'Example Topic'
}
response = service.courses().topics().create(
  courseId=<course ID or alias>,
  body=topic).execute()
print('Topic created: ', response['name'])

Mengambil detail topik

Anda dapat mengambil topik kursus yang sesuai dengan metode topics.get(), seperti yang ditunjukkan dalam contoh berikut:

Java

classroom/snippets/src/main/java/GetTopic.java
Topic topic = null;
try {
  // Get the topic.
  topic = service.courses().topics().get(courseId, topicId).execute();
  System.out.printf("Topic '%s' found.\n", topic.getName());
} catch (GoogleJsonResponseException e) {
  // TODO (developer) - handle error appropriately
  GoogleJsonError error = e.getDetails();
  if (error.getCode() == 404) {
    System.out.printf("The courseId or topicId does not exist: %s, %s.\n", courseId, topicId);
  }
  throw e;
} catch (Exception e) {
  throw e;
}
return topic;

Python

response = service.courses().topics().get(
  courseId=<course ID or alias>,
  id=<topic ID>).execute()
print('{0} ({1})'.format(response['name'], response['topicId']))

Untuk daftar kursus, gunakan metode topics.list(), seperti yang ditunjukkan dalam contoh berikut:

Java

classroom/snippets/src/main/java/ListTopics.java
List<Topic> topics = new ArrayList<>();
String pageToken = null;

try {
  do {
    ListTopicResponse response =
        service
            .courses()
            .topics()
            .list(courseId)
            .setPageSize(100)
            .setPageToken(pageToken)
            .execute();

    /* Ensure that the response is not null before retrieving data from it to avoid errors. */
    if (response.getTopic() != null) {
      topics.addAll(response.getTopic());
      pageToken = response.getNextPageToken();
    }
  } while (pageToken != null);

  if (topics.isEmpty()) {
    System.out.println("No topics found.");
  } else {
    for (Topic topic : topics) {
      System.out.printf("%s (%s)\n", topic.getName(), topic.getTopicId());
    }
  }
} catch (GoogleJsonResponseException e) {
  // TODO (developer) - handle error appropriately
  GoogleJsonError error = e.getDetails();
  if (error.getCode() == 404) {
    System.out.printf("The courseId does not exist: %s.\n", courseId);
  } else {
    throw e;
  }
} catch (Exception e) {
  throw e;
}
return topics;

Python

topics = []
page_token = None
while True:
    response = service.courses().topics().list(
        pageToken=page_token,
        pageSize=30,
        courseId=<course ID or alias>).execute()
    topics.extend(response.get('topic', []))
    page_token = response.get('nextPageToken', None)
    if not page_token:
        break
if not topics:
    print('No topics found.')
else:
    print('Topics:')
    for topic in topics:
        print('{0} ({1})'.format(topic['name'], topic['topicId']))

Perbarui beberapa topik

Anda dapat memperbarui nama topik yang ada dengan metode topics.patch(), seperti yang ditunjukkan dalam contoh berikut:

Java

classroom/snippets/src/main/java/UpdateTopic.java
Topic topic = null;
try {
  // Retrieve the topic to update.
  Topic topicToUpdate = service.courses().topics().get(courseId, topicId).execute();

  // Update the name field for the topic retrieved.
  topicToUpdate.setName("Semester 2");

  /* Call the patch endpoint and set the updateMask query parameter to the field that needs to
  be updated. */
  topic =
      service
          .courses()
          .topics()
          .patch(courseId, topicId, topicToUpdate)
          .set("updateMask", "name")
          .execute();

  /* Prints the updated topic. */
  System.out.printf("Topic '%s' updated.\n", topic.getName());
} catch (GoogleJsonResponseException e) {
  // TODO(developer) - handle error appropriately
  GoogleJsonError error = e.getDetails();
  if (error.getCode() == 404) {
    System.out.printf("The courseId or topicId does not exist: %s, %s.\n", courseId, topicId);
  } else {
    throw e;
  }
} catch (Exception e) {
  throw e;
}
return topic;

Python

topic = {
  "name": "New Topic Name"
}
response = service.courses().topics().patch(
  courseId=<course ID or alias>,
  id=<topic ID>,
  updateMask="name",
  body=topic).execute()
print('{0} ({1})'.format(response['name'], response['topicId']))

Hapus topik

Anda dapat menghapus topik yang ada dengan metode topics.delete(), seperti yang ditunjukkan dalam contoh berikut:

Java

classroom/snippets/src/main/java/DeleteTopic.java
try {
  service.courses().topics().delete(courseId, topicId).execute();
} catch (GoogleJsonResponseException e) {
  // TODO(developer) - handle error appropriately
  throw e;
} catch (Exception e) {
  throw e;
}
