列出聊天室

本指南介绍了如何对 Google Chat API 的 Space 资源使用 list() 方法来列出聊天室。列出聊天室会返回可分页且可过滤的聊天室列表。

Space 资源表示用户和 Chat 应用可以发送消息、共享文件和协作的场所。聊天室有以下几种类型：

  • 私信 (DM) 是指两位用户或用户与 Chat 应用之间的对话。
  • 群聊是三位或更多用户与 Chat 应用之间的对话。
  • 命名聊天室是用户发送消息、共享文件和协作的永久性场所。

使用应用身份验证列出聊天应用有权访问的聊天室。使用用户身份验证列出聊天室会列出已通过身份验证的用户有权访问的聊天室。

列出需要用户身份验证的聊天室

如需列出 Google Chat 中的聊天室，请在请求中传递以下内容：

以下示例列出了经过身份验证的用户可以看到的已命名聊天室（但不包括过滤掉的群聊和私信）：

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)

import com.google.chat.v1.ListSpacesResponse;

// 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 {

        // 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 脚本

chat/advanced-service/Main.gs
/**

 * 
 * 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 会返回分页聊天室列表。

列出需要应用身份验证的聊天室

如需列出 Google Chat 中的聊天室，请在请求中传递以下内容：

以下示例列出了 Chat 应用可见的命名聊天室（但不包括群聊和私信）：

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);

    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 会返回分页聊天室列表。

自定义分页或过滤列表

如需在 Google Chat 中列出聊天室，请传递以下可选查询参数，以自定义列出聊天室的分页或过滤列出聊天室：

  • pageSize：要返回的空格数上限。服务返回的数量可能小于此值。如果未指定，则最多返回 100 个空格。最大值为 1,000；大于 1,000 的值会自动更改为 1,000。
  • pageToken：从上一个列出聊天室的调用接收的页面令牌。 提供此令牌以检索后续页面。进行分页时，过滤条件值应与提供页面令牌的调用相一致。传递不同的值可能会导致意外结果。
  • filter：查询过滤条件。如需了解支持的查询详情，请参阅 ListSpacesRequest 参考文档。
