Java

1. Dalam direktori project Anda, buka file src/main/java/com/google/chat/app/authsample/App.java.

2. Ganti konten di App.java dengan kode berikut:

   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.services.chat.v1.model.Space;
   
   import java.io.InputStreamReader;
   import java.util.Collection;
   import java.util.Collections;

               Space response = App.createChatSpace(userCredential);
               // Print details about the created space.
               System.out.println(response);
           } catch (Exception e) {
               e.printStackTrace();
           }
       }
   
       /**

           return chatService.spaces().create(space).execute();
       }
   }
   

3. Buat subdirektori baru bernama resources dalam direktori project Anda.

4. Salin file client_secrets.json ke subdirektori resources.

5. Untuk mengonfigurasi Maven agar menyertakan file rahasia klien dalam paket project, edit file pom.xml di direktori project Anda dan tambahkan konfigurasi berikut ke bagian <build>:

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

6. Untuk mengonfigurasi Maven agar menyertakan dependensi dalam paket project dan menjalankan class utama aplikasi Anda, edit file pom.xml di direktori project dan tambahkan konfigurasi berikut ke bagian <plugins>:

   <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. Simpan kode berikut dalam file bernama chat_space_create_named.py di direktori yang sama yang menyimpan client_secrets.json:

   from __future__ import print_function
   
   import os.path
   
   from google.auth.transport.requests import Request
   from google.oauth2.credentials import Credentials
   from google_auth_oauthlib.flow import InstalledAppFlow
   from googleapiclient.discovery import build
   from googleapiclient.errors import HttpError
   
   # 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. Simpan kode berikut dalam file bernama chat_space_create_named.js di direktori yang sama dengan yang menyimpan project Node.js dan client_secrets.json:

   const fs = require('fs');
   const path = require('path');
   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;

   // 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(' '),

             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);
   

Apps Script

1. Di editor Apps Script, edit file appsscript.json dan tambahkan cakupan OAuth yang diperlukan untuk memanggil API:

     "oauthScopes": [
       "https://www.googleapis.com/auth/chat.spaces.create"
     ]
   

2. Simpan kode berikut dalam file bernama ChatSpaceCreateNamed.gs di project Apps Script:

   /**
    * Authenticates with Chat API via user credentials, then creates a
    * Chat space.
    */
   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);
     }
   }
