列出聊天室

本指南說明如何使用 Google Chat API Space 資源的 list() 方法列出聊天室。列出空間會傳回可分頁顯示和篩選的空間清單。

Space資源代表使用者和 Chat 應用程式可傳送訊息、共用檔案及協作的空間。聊天室分為以下幾種類型：

  • 即時訊息 (DM) 是指兩位使用者之間，或使用者與 Chat 應用程式之間的對話。
  • 群組對話是指三位以上使用者和即時通訊應用程式之間的對話。
  • 具名聊天室是持續存在的空間，可供使用者傳送訊息、分享檔案及協作。

使用應用程式驗證列出聊天室時，系統會列出 Chat 應用程式有權存取的聊天室。列出具有使用者驗證的空間：列出已驗證使用者可存取的空間。

必要條件

Node.js

Python

Java

Apps Script

列出具有使用者驗證的空間

如要列出 Google Chat 中的聊天室，請在要求中傳遞下列項目：

以下範例列出經過驗證的使用者可見的具名聊天室 (但會篩除群組對話和即時訊息)：

Node.js

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

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

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

  // Initialize request argument(s)
  const request = {
    // Filter spaces by space type (SPACE or GROUP_CHAT or DIRECT_MESSAGE)
    filter: 'space_type = "SPACE"'
  };

  // Make the request
  const pageResult = chatClient.listSpacesAsync(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_spaces_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.spaces.readonly"]

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

    # Initialize request argument(s)
    request = google_chat.ListSpacesRequest(
        # Filter spaces by space type (SPACE or GROUP_CHAT or DIRECT_MESSAGE)
        filter = 'space_type = "SPACE"',
        # Number of results that will be returned at once
        page_size = 100
    )

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

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

list_spaces_with_user_cred()

Java

chat/client-libraries/cloud/src/main/java/com/google/workspace/api/chat/samples/ListSpacesUserCred.java
import com.google.chat.v1.ChatServiceClient;
import com.google.chat.v1.ListSpacesRequest;
import com.google.chat.v1.ListSpacesResponse;
import com.google.chat.v1.Space;

// This sample shows how to list spaces with user credential.
public class ListSpacesUserCred{

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

  public static void main(String[] args) throws Exception {
    try (ChatServiceClient chatServiceClient =
        AuthenticationUtils.createClientWithUserCredentials(
          ImmutableList.of(SCOPE))) {
      ListSpacesRequest.Builder request = ListSpacesRequest.newBuilder()
        // Filter spaces by space type (SPACE or GROUP_CHAT or
        // DIRECT_MESSAGE).
        .setFilter("spaceType = \"SPACE\"")
        // Number of results that will be returned at once.
        .setPageSize(10);

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

Apps Script

chat/advanced-service/Main.gs
/**
 * This sample shows how to list spaces with user credential
 * 
 * It relies on the OAuth2 scope 'https://www.googleapis.com/auth/chat.spaces.readonly'
 * referenced in the manifest file (appsscript.json).
 */
function listSpacesUserCred() {
  // Initialize request argument(s)
  // Filter spaces by space type (SPACE or GROUP_CHAT or DIRECT_MESSAGE)
  const filter = 'space_type = "SPACE"';

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

Chat API 會傳回分頁列出的空間清單。

使用應用程式驗證列出空間

如要列出 Google Chat 中的聊天室，請在要求中傳遞下列項目：

以下範例會列出 Chat 應用程式可見的具名聊天室 (但不包括群組即時通訊和即時訊息)：

Node.js

chat/client-libraries/cloud/list-spaces-app-cred.js
import {createClientWithAppCredentials} from './authentication-utils.js';

// This sample shows how to list spaces with app credential
async function main() {
  // Create a client
  const chatClient = createClientWithAppCredentials();

  // Initialize request argument(s)
  const request = {
    // Filter spaces by space type (SPACE or GROUP_CHAT or DIRECT_MESSAGE)
    filter: 'space_type = "SPACE"'
  };

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

# This sample shows how to list spaces with app credential
def list_spaces_app_cred():
    # Create a client
    client = create_client_with_app_credentials()

    # Initialize request argument(s)
    request = google_chat.ListSpacesRequest(
        # Filter spaces by space type (SPACE or GROUP_CHAT or DIRECT_MESSAGE)
        filter = 'space_type = "SPACE"',
        # Number of results that will be returned at once
        page_size = 100
    )

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

    # Handle the response. Iterating over page_result will yield results and

Chat API 會傳回分頁列出的空間清單。

自訂分頁或篩選清單

如要在 Google Chat 中列出聊天室，請傳遞下列選用查詢參數，自訂列出聊天室的分頁或篩選條件：

  • pageSize：要傳回的空間數量上限。服務傳回的產品數量可能會少於這個值。如未指定，最多將傳回 100 個空間。最大值為 1,000；超過 1,000 的值會自動變更為 1,000。
  • pageToken：先前呼叫 list spaces 時收到的頁面權杖。 提供此權杖即可擷取後續網頁。進行分頁時，篩選器值應與提供網頁權杖的呼叫相符。傳遞其他值可能會導致非預期的結果。
  • filter：查詢篩選器。如需支援的查詢詳細資料，請參閱ListSpacesRequest參考資料。
