// Authenticate and get a credential Credential credential = flow.loadToken();
// List files Drive drive = new Drive.Builder( GoogleNetHttpTransport.newTrustedTransport(), GsonFactory.getDefaultInstance(), credential ).build();
Here's an example of how to list files in Google Drive: jav google drive work
Here's an example of how to authenticate with the Google Drive API and upload a file:
import java.io.FileOutputStream; import java.io.InputStream; // Authenticate and get a credential Credential credential
List<com.google.api.services.drive.model.File> files = drive.files().list().execute().getFiles(); for (com.google.api.services.drive.model.File file : files) { System.out.println(file.getName()); } } } That's it! With these steps, you should be able to use Google Drive in your Java application.
import java.io.File; import java.io.FileInputStream; import java.util.Arrays; files = drive.files().list().execute().getFiles()
public class GoogleDriveExample { public static void main(String[] args) throws Exception { // Load client secrets GoogleClientSecrets clientSecrets = GoogleClientSecrets.load( GsonFactory.getDefaultInstance(), new FileInputStream("client_secrets.json") );
// Set up authorization flow GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder( GoogleNetHttpTransport.newTrustedTransport(), GsonFactory.getDefaultInstance(), clientSecrets, Arrays.asList(DriveScopes.DRIVE_FILE) ).build();
// Upload a file File file = new File("example.txt"); FileContent fileContent = new FileContent("text/plain", file); com.google.api.services.drive.model.File driveFile = new com.google.api.services.drive.model.File(); driveFile.setName("example.txt"); driveFile.setMimeType("text/plain"); drive.files().insert(driveFile, fileContent).execute(); } }
// Create a Drive service Drive drive = new Drive.Builder( GoogleNetHttpTransport.newTrustedTransport(), GsonFactory.getDefaultInstance(), credential ).build();
