   package com.google.chat.app.authsample;
   
   import com.google.api.client.auth.oauth2.Credential;
   import com.google.api.client.extensions.java6.auth.oauth2.AuthorizationCodeInstalledApp;
   import com.google.api.client.extensions.jetty.auth.oauth2.LocalServerReceiver;
   import com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeFlow;
   import com.google.api.client.googleapis.auth.oauth2.GoogleClientSecrets;
   import com.google.api.client.googleapis.javanet.GoogleNetHttpTransport;
   import com.google.api.client.http.HttpTransport;
   import com.google.api.client.json.JsonFactory;
   import com.google.api.client.json.gson.GsonFactory;
   import com.google.api.client.util.store.FileDataStoreFactory;
   import com.google.api.services.chat.v1.HangoutsChat;
   import com.google.api.services.chat.v1.model.Space;
   
   import java.io.InputStreamReader;
   import java.util.Collection;
   import java.util.Collections;
   
   /**
    * Authenticates with Chat API via user credentials, then creates a Chat space.
    */
   public class App {
       // Application OAuth credentials.
       private static final String KEYS_RESOURCE_URI = "/client_secrets.json";
   
       // Define your app's authorization scopes.
       private static final Collection<String> SCOPES =
           Collections.singleton("https://www.googleapis.com/auth/chat.spaces.create");
   
       // Directory to store user credentials.
       private static final java.io.File DATA_STORE_DIR =
           new java.io.File(System.getProperty("user.home"), ".store/auth-sample-app");
   
       // Global instance of the JSON factory.
       private static final JsonFactory JSON_FACTORY = GsonFactory.getDefaultInstance();
   
       // Global instance of the HTTP transport.
       private static HttpTransport httpTransport;
   
       // Global instance of the DataStoreFactory. The best practice is to make it a single
       // globally shared instance across your application.
       private static FileDataStoreFactory dataStoreFactory;
   
       public static void main( String[] args ) {
           try {
               // Run app.
               httpTransport = GoogleNetHttpTransport.newTrustedTransport();
               dataStoreFactory = new FileDataStoreFactory(DATA_STORE_DIR);
               Credential userCredential = authorize();
               Space response = App.createChatSpace(userCredential);
               // Print details about the created space.
               System.out.println(response);
           } catch (Exception e) {
               e.printStackTrace();
           }
       }
   
       /**
        * Authorizes the installed application to access user's protected data.
        */
       private static Credential authorize() throws Exception {
           // Load client secrets.
           GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY,
               new InputStreamReader(App.class.getResourceAsStream("/client_secrets.json")));
           // Set up authorization code flow.
           GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
               httpTransport, JSON_FACTORY, clientSecrets, SCOPES)
               .setDataStoreFactory(dataStoreFactory)
               .build();
           // Authorize.
           return new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize("user");
       }
   
       /**
        * Creates a Chat space.
        */
       private static Space createChatSpace(Credential userCredential) throws Exception {
           // Build the Chat API client and authenticate with the user account.
           HangoutsChat chatService = new HangoutsChat.Builder(
               httpTransport, JSON_FACTORY, userCredential)
               .setApplicationName("auth-sample-app")
               .build();
   
           // Create a Chat space.
           Space space = new Space()
               // To create a named space, set spaceType to SPACE.
               .setSpaceType("SPACE")
               // The user-visible name of the space.
               .setDisplayName("API-made");
           return chatService.spaces().create(space).execute();
       }
   }
   

3. 在项目的目录中创建一个名为 resources 的新子目录。

4. 将 client_secrets.json 文件复制到 resources 子目录。

5. 如需配置 Maven 以在项目软件包中添加客户端密钥文件，请修改项目目录中的 pom.xml 文件，并将以下配置添加到 <build> 部分：

   <build>
     <!-- ... existing configurations ... -->
     <resources>
       <resource>
         <directory>resources</directory>
       </resource>
     </resources>
   </build>
   

6. 如需配置 Maven 以在项目软件包中添加依赖项并执行应用的主类，请修改项目目录中的 pom.xml 文件，并将以下配置添加到 <plugins> 部分：

   <plugins>
     <!-- ... existing configurations ... -->
     <plugin>
       <artifactId>maven-assembly-plugin</artifactId>
       <configuration>
         <archive>
           <manifest>
             <mainClass>com.google.chat.app.authsample.App</mainClass>
           </manifest>
         </archive>
         <descriptorRefs>
           <descriptorRef>jar-with-dependencies</descriptorRef>
         </descriptorRefs>
       </configuration>
     </plugin>
   </plugins>
   

Python

1. 将以下代码保存到 client_secrets.json 所在目录内名为 chat_space_create_named.py 的文件中：

   from google_auth_oauthlib.flow import InstalledAppFlow
   from googleapiclient.discovery import build
   
   # Define your app's authorization scopes.
   # When modifying these scopes, delete the file token.json, if it exists.
   SCOPES = ["https://www.googleapis.com/auth/chat.spaces.create"]
   
   def main():
     '''
     Authenticates with Chat API via user credentials,
     then creates a Chat space.
     '''
   
     flow = InstalledAppFlow.from_client_secrets_file(
                       'client_secrets.json', SCOPES)
     creds = flow.run_local_server()
   
     # Build a service endpoint for Chat API.
     service = build('chat', 'v1', credentials=creds)
   
     # Use the service endpoint to call Chat API.
     result = service.spaces().create(
   
       # Details about the space to create.
       body = {
   
         # To create a named space, set spaceType to SPACE.
         'spaceType': 'SPACE',
   
         # The user-visible name of the space.
         'displayName': 'API-made'
   
       }
   
     ).execute()
   
     # Prints details about the created space.
     print(result)
   
   if __name__ == '__main__':
     main()
   

Node.js

1. 将以下代码保存在包含 Node.js 项目和 client_secrets.json 的目录中名为 chat_space_create_named.js 的文件中：

   const fs = require('fs');

   const http = require('http');
   const url = require('url');
   const destroyer = require('server-destroy');
   
   const chat = require('@googleapis/chat');
   
   // Application OAuth credentials.
   const keys = require('./client_secrets.json').installed;
   
   // Define your app's authorization scopes.
   // When modifying these scopes, delete the file token.json, if it exists.
   const scopes = ["https://www.googleapis.com/auth/chat.spaces.create"];
   
   // Create a new OAuth2 client with the configured keys.
   const oauth2Client = new chat.auth.OAuth2(
     keys.client_id,
     keys.client_secret,
     'http://localhost:3000'
   );
   
   /**
    * Opens an HTTP server to accept the OAuth callback.
    * In this simple example, the only request to our webserver is to /?code=<code>.
    */
   async function authenticate(scopes) {
     const opn = (await import('open')).default;
   
     return new Promise((resolve, reject) => {
       // Generate the URL for authorization.
       const authorizeUrl = oauth2Client.generateAuthUrl({
         access_type: 'offline',
         scope: scopes.join(' '),
       });
       // Start the HTTP server to listen for the callback.
       const server = http
         .createServer(async (req, res) => {
           try {
             const qs = new url.URL(req.url, 'http://localhost:3000').searchParams;
             res.end('Authentication successful! Please return to the console.');
             server.destroy();
             const { tokens } = await oauth2Client.getToken(qs.get('code'));
             oauth2Client.credentials = tokens;
             resolve(oauth2Client);
           } catch (e) {
             reject(e);
           }
         })
         .listen(3000, () => {
           // Open the browser to the authorize URL to start the workflow.
           opn(authorizeUrl, { wait: false }).then(cp => cp.unref());
         });
       destroyer(server);
     });
   }
   
   /**
    * Authenticates with Chat API via user credentials, then creates a Chat space.
    */
   async function createSpace() {
     // Create the Chat API client and authenticate with the authorized user.
     const chatClient = await chat.chat({
       version: 'v1',
       auth: oauth2Client
     });
   
     // Call the Chat API to create a space.
     const result = await chatClient.spaces.create({
   
       // Details about the space to create.
       requestBody: {
   
         // To create a named space, set spaceType to SPACE.
         'spaceType': 'SPACE',
   
         // The user-visible name of the space.
         'displayName': 'API-made'
   
       }
   
     });
     return result;
   }
   
   // Authenticate the user, execute the function,
   // then print details about the created space.
   authenticate(scopes)
     .then(createSpace)
     .then(console.log);

   function createSpace() {
     try {
       // Details about the space to create.
       // To create a named space, set spaceType to SPACE.
       // The user-visible name of the space is displayName.
       const space = {'displayName': 'API-made', 'spaceType': 'SPACE'};
   
       // Call Chat API with user credentials to create the space.
       const result = Chat.Spaces.create(space);
   
       // Log details about the created space.
       console.log(result);
     } catch (err) {
       // TODO (developer) - Handle exception
       console.log('Failed to create space with error %s', err.message);
     }
