I am using a Google Service account to create Google Drive resources.
However when i try to execute Drive create folder API i get connection reset error.
I can confirm that the credentials for the service account are properly configured and loaded in my program.
Below is the code and the stacktrace
public static File createFolder(Drive driveService) {
File fileMetadata = new File();
fileMetadata.setName("Testing");
fileMetadata.setMimeType("application/vnd.google-apps.folder");
File file =null;
try {
file = driveService.files().create(fileMetadata)
.setFields("id")
.execute();
} catch (IOException e) {
// TODO Auto-generated catch block
System.out.println("Exception here in create folder");
e.printStackTrace();
}
System.out.println("Folder ID: " file.getId());
return file;
}
Below is how the credentials are read and instance of Drive is created
/**
* Creates credentials for the service account
* @param HTTP_TRANSPORT
* @return
* @throws IOException
*/
private static Credential getServiceAccountCredential(final NetHttpTransport HTTP_TRANSPORT) throws IOException {
InputStream in = DriveQuickStart.class.getResourceAsStream(CREDENTIALS_FILE_PATH);
if (in == null) {
throw new FileNotFoundException("Resource not found: " CREDENTIALS_FILE_PATH);
}
GoogleCredential credential = GoogleCredential.fromStream(in)
.createScoped(SCOPES);
System.out.println("loaded credential " credential.getServiceAccountId()) ;
return credential;
}
public static void main(String... args) throws IOException, GeneralSecurityException {
// Build a new authorized API client service.
final NetHttpTransport HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
SCOPES.add(DriveScopes.DRIVE_FILE);
Drive service = new Drive.Builder(HTTP_TRANSPORT, JSON_FACTORY, getServiceAccountCredential(HTTP_TRANSPORT))
.setApplicationName(APPLICATION_NAME)
.build();
//create folder
File parentFolder = createFolder(service);

CodePudding user response：
you are using DriveScopes.DRIVE_FILE this scope can act a bit strange sometimes. Its basicly used to lock an application and only allow it to edit files that it created itself. When creating folders I have found it can act very strangely if the directory its creating is not inside a directory it created in the first place.
https://www.googleapis.com/auth/drive See, edit, create, and delete all of your Google Drive files
The solution is to just use. DriveScopes.DRIVE technically you are using a service account anyway there is really no reason to limit it.
https://www.googleapis.com/auth/drive.file View and manage Google Drive files and folders that you have opened or created with this app
