Creating a file in Google Drive (G Suite) from Java with Service Account: 403 Insufficient Permission
问题
我正在尝试在Google Drive文件夹中创建一个文件。
从文件夹中读取是有效的。我已经在不同应用程序中使用不同服务账号读取文件。
我已将我的G Suite Drive文件夹与生成的服务账号电子邮件共享，并赋予了编辑者访问权限（读取、写入、编辑）。
我试图从我的Java Springboot应用程序复制一个现有文件（也可以从头开始创建一个空文件）。
public class TemplateDocumentManager {@Value("${printing.template.id}")private String baseTemplateFileId;@Autowiredprivate Drive driveService;public void createNewContractFromEmptyTemplate() throws IOException {File templateFile = getDriveFiles().get(baseTemplateFileId).execute();File newFileInstance = getDriveFiles().copy(baseTemplateFileId, templateFile).setSupportsAllDrives(true).execute();log.error("Id of newly created file is: {}", newFileInstance.getId());}protected Drive.Files getDriveFiles() {return driveService.files();}}
使用@Autowired注解注入的Google Drive服务运行良好。它的创建方式如下：
@Configurationpublic class DriveService {public static final String APPLICATION_NAME = "appname";@AutowiredGoogleCredential googleCredential;@Bean("driveService")public Drive createDriveService() throws GeneralSecurityException, IOException {return new Drive.Builder(GoogleNetHttpTransport.newTrustedTransport(), JacksonFactory.getDefaultInstance(), googleCredential).setApplicationName(APPLICATION_NAME).build();}...}
关于服务账号需要什么权限才能在G Suite Drive文件夹上进行写入，有什么想法吗？
英文:
I'm trying to create a file in a Google Drive folder.
Reading from the folder works. I'm already reading files in different applications with different Service Accounts.
I shared my G Suite Drive folder with the generated service account email and gave it Editor access (read, write, edit).
I tried to copy an existing file (but also create an empty one from scratch) from my Java Springboot application.
public class TemplateDocumentManager {@Value("${printing.template.id}")private String baseTemplateFileId;@Autowiredprivate Drive driveService;public void createNewContractFromEmptyTemplate() throws IOException {File templateFile = getDriveFiles().get(baseTemplateFileId).execute();File newFileInstance = getDriveFiles().copy(baseTemplateFileId, templateFile).setSupportsAllDrives(true).execute();log.error("Id of newly created file is: {}", newFileInstance.getId());}protected Drive.Files getDriveFiles() {return driveService.files();}}
The google drive service injected with the @Autowired annotation is working properly. It is created as follows:
@Configurationpublic class DriveService {public static final String APPLICATION_NAME = "appname";@AutowiredGoogleCredential googleCredential;@Bean("driveService")public Drive createDriveService() throws GeneralSecurityException, IOException {return new Drive.Builder(GoogleNetHttpTransport.newTrustedTransport(), JacksonFactory.getDefaultInstance(), googleCredential).setApplicationName(APPLICATION_NAME).build();}...}
Any ideas on what the service account needs to be able to write on the G Suite Drive folder?

你必须为GoogleCredentials对象授予所需的权限，即：
GoogleCredential.fromStream(source).createScoped(scopes)
作用域可以在SheetsScopes或DriveScopes中找到（取决于您的Google依赖项）。
英文:
You have to give the required permissions to the GoogleCredentials Object, i.e.
GoogleCredential.fromStream(source).createScoped(scopes)
Scopes could be found in e.g. SheetsScopes or DriveScopes ( depending on your Google dependencies )
