Membuat daftar pesan

Panduan ini menjelaskan cara menggunakan list() di resource Message Google Chat API untuk melihat halaman yang telah diberi nomor halaman, daftar pesan yang dapat difilter dalam ruang.

Di Chat API, pesan Chat diwakili oleh resource Message. Meskipun pengguna Chat hanya dapat mengirim pesan yang berisi teks, Aplikasi chat dapat menggunakan banyak fitur pesan lainnya, termasuk menampilkan antarmuka pengguna yang statis atau interaktif, mengumpulkan informasi dari pengguna, dan mengirim pesan secara pribadi. Untuk mempelajari lebih lanjut fitur pesan yang tersedia untuk Chat API, lihat ringkasan pesan Google Chat.

Mencantumkan pesan

Untuk mencantumkan pesan dengan autentikasi pengguna, teruskan hal berikut dalam permintaan Anda:

  • Tentukan cakupan otorisasi chat.messages.readonly atau chat.messages.
  • Panggil metode ListMessages().

Contoh berikut mencantumkan pesan di ruang Chat:

Node.js

chat/client-libraries/cloud/list-messages-user-cred.js
import {createClientWithUserCredentials} from './authentication-utils.js';

const USER_AUTH_OAUTH_SCOPES = ['https://www.googleapis.com/auth/chat.messages.readonly'];

// This sample shows how to list messages with user credential
async function main() {
  // Create a client
  const chatClient = await createClientWithUserCredentials(USER_AUTH_OAUTH_SCOPES);

  // Initialize request argument(s)
  const request = {
    // Replace SPACE_NAME here
    parent: 'spaces/SPACE_NAME'
  };

  // Make the request
  const pageResult = chatClient.listMessagesAsync(request);

  // Handle the response. Iterating over pageResult will yield results and
  // resolve additional pages automatically.
  for await (const response of pageResult) {
    console.log(response);
  }
}

main().catch(console.error);

Python

chat/client-libraries/cloud/list_messages_user_cred.py
from authentication_utils import create_client_with_user_credentials
from google.apps import chat_v1 as google_chat

SCOPES = ["https://www.googleapis.com/auth/chat.messages.readonly"]

# This sample shows how to list messages with user credential
def list_messages_with_user_cred():
    # Create a client
    client = create_client_with_user_credentials(SCOPES)

    # Initialize request argument(s)
    request = google_chat.ListMessagesRequest(
        # Replace SPACE_NAME here
        parent = 'spaces/SPACE_NAME',
        # Number of results that will be returned at once
        page_size = 100
    )

    # Make the request
    page_result = client.list_messages(request)

    # Handle the response. Iterating over page_result will yield results and
    # resolve additional pages automatically.
    for response in page_result:
        print(response)

list_messages_with_user_cred()

Java

chat/client-libraries/cloud/src/main/java/com/google/workspace/api/chat/samples/ListMessagesUserCred.java
import com.google.chat.v1.ChatServiceClient;
import com.google.chat.v1.ListMessagesRequest;
import com.google.chat.v1.ListMessagesResponse;
import com.google.chat.v1.Message;

// This sample shows how to list messages with user credential.
public class ListMessagesUserCred {

  private static final String SCOPE =
    "https://www.googleapis.com/auth/chat.messages.readonly";

  public static void main(String[] args) throws Exception {
    try (ChatServiceClient chatServiceClient =
        AuthenticationUtils.createClientWithUserCredentials(
          ImmutableList.of(SCOPE))) {
      ListMessagesRequest.Builder request = ListMessagesRequest.newBuilder()
        // Replace SPACE_NAME here.
        .setParent("spaces/SPACE_NAME")
        // Number of results that will be returned at once.
        .setPageSize(10);

      // Iterate over results and resolve additional pages automatically.
      for (Message response :
          chatServiceClient.listMessages(request.build()).iterateAll()) {
        System.out.println(JsonFormat.printer().print(response));
      }
    }
  }
}

Apps Script

chat/advanced-service/Main.gs
/**
 * This sample shows how to list messages with user credential
 * 
 * It relies on the OAuth2 scope 'https://www.googleapis.com/auth/chat.messages.readonly'
 * referenced in the manifest file (appsscript.json).
 */
function listMessagesUserCred() {
  // Initialize request argument(s)
  // TODO(developer): Replace SPACE_NAME here
  const parent = 'spaces/SPACE_NAME';

  // Iterate through the response pages using page tokens
  let responsePage;
  let pageToken = null;
  do {
    // Request response pages
    responsePage = Chat.Spaces.Messages.list(parent, {
      pageSize: 10,
      pageToken: pageToken
    });
    // Handle response pages
    if (responsePage.messages) {
      responsePage.messages.forEach((message) => console.log(message));
    }
    // Update the page token to the next one
    pageToken = responsePage.nextPageToken;
  } while (pageToken);
}

Untuk menjalankan contoh ini, ganti SPACE_NAME dengan ID dari kolom name ruang. Anda bisa mendapatkan ID dengan memanggil ListSpaces() atau dari URL ruang.

Chat API menampilkan daftar pesan dikirim ke ruang yang ditentukan. Jika tidak ada pesan dari permintaan, Respons Chat API menampilkan objek kosong. Saat menggunakan REST/HTTP , respons akan berisi objek JSON kosong, {}.
