列出聊天室

本指南介绍了如何使用 list() Google Chat API 的 Space 资源中的方法列出聊天室。列出聊天室会返回一个可过滤的分页聊天室列表。

`Space` 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。聊天室有多种类型：

  • 私信 (DM) 是两位用户之间或用户与 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场所。

使用 应用身份验证 列出聊天室会列出 Chat 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。

使用用户身份验证列出聊天室

如需列出 Google Chat 中的聊天室，请在请求中传递以下内容：

以下示例列出了已通过身份验证的用户可见的命名聊天室（但不包括群聊和私信，这些内容会被过滤掉）：

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);
  }
}

await main();

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()

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 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) {
      for (const space of responsePage.spaces) {
        console.log(space);
      }
    }
    // Update the page token to the next one
    pageToken = responsePage.nextPageToken;
  } while (pageToken);
}

Chat API 会返回一个 分页聊天室列表。

使用应用身份验证列出聊天室

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）：

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);
  }
}

await main();

from authentication_utils import create_client_with_app_credentials
from google.apps import chat_v1 as google_chat

# 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
    # resolve additional pages automatically.
    for response in page_result:

  } while (pageToken);
}

Chat API 会返回一个 分页聊天室列表。

自定义分页或过滤列表

如需列出 Google Chat 中的聊天室，请传递以下可选查询参数来自定义分页或过滤列出的聊天室：

  • pageSize：要返回的聊天室数量上限。服务可能会返回小于此值的结果。如果未指定，则最多返回 100 个聊天室。最大值为 1,000；如果值高于 1,000，则会自动更改为 1,000。
  • pageToken：从之前的列出聊天室调用中收到的页面令牌。 提供此令牌可检索后续页面。进行分页时，过滤条件值应与提供页面令牌的调用匹配。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。
