Uploading data to shared drive using service account in java
问题
我想使用Java将文件上传到共享驱动器。
我已经创建了一个服务帐户,并且已经与服务帐户的地址共享了共享驱动器(名称为DB-Drive)。
全局变量
private static HttpTransport httpTransport;
private static Drive drive;
主要函数(初始化和列出文件)
httpTransport = GoogleNetHttpTransport.newTrustedTransport();
Credential credential = authorize();
drive = new Drive.Builder(httpTransport, JacksonFactory.getDefaultInstance(), credential).setApplicationName(
"Quickstart").build();
uploadFile();
FileList result = drive.files().list().execute();
List<File> files = result.getFiles();
if (result == null || result.isEmpty()) {
System.out.println("No files found.");
} else {
System.out.println("Files:");
for (File file : files) {
System.out.printf("%s %s \n", file.getName(), file.getId());
}
}
授权代码
GoogleCredential credential = GoogleCredential.fromStream(new FileInputStream("resources/credentials.json"))
.createScoped(Collections.singleton(DriveScopes.DRIVE_FILE));
return credential;
上传代码
String folderId = "***DB-Drive id****";
File fileMetadata = new File();
fileMetadata.setName("photo.jpg");
fileMetadata.setParents(Collections.singletonList(folderId));
java.io.File filePath = new java.io.File("/home/*****/Downloads/qck_1552369371.jpeg");
FileContent mediaContent = new FileContent("image/jpeg", filePath);
File file = drive.files().create(fileMetadata, mediaContent)
.setFields("id, parents")
.execute();
System.out.println("File ID: " + file.getId());
return file;
我正在将DB-Drive设置为上传文件的父级,但仍然无法在共享驱动器文件夹中查看它。请帮助我。
我正在添加完整的流程:
1.) 我使用https://developers.google.com/identity/protocols/oauth2/service-account上的步骤创建了服务帐户。
我选择了项目并提供了描述等信息。
2.) 我没有为服务帐户提供域级别的委派,而是使用了服务帐户地址共享了DB-drive(团队驱动器)(该地址在credentials.json文件中作为client_email *****.gserviceaccount.com进行了提及)。
3.) 然后,我使用上面的代码要求服务帐户将文件上传到共享驱动器,即DB-Drive,通过指定DB-Drive的ID作为文件的父ID。
4.) 但是文件仍然上传到服务帐户的驱动器,而没有链接到共享驱动器。
5.) DB-Drive是父文件夹(唯一的文件夹)。
任何线索都将是极大的帮助。

I want to upload the files to shared drive using java.
I have created a service account and I have shared the shared-drive (name is DB-Drive) with the service account's address.
Global variables
private static HttpTransport httpTransport;
private static Drive drive;
Main function (initialize and listing of the files)
httpTransport = GoogleNetHttpTransport.newTrustedTransport();
Credential credential = authorize();
drive = new Drive.Builder(httpTransport, JacksonFactory.getDefaultInstance(), credential).setApplicationName(
"Quickstart").build();
uploadFile();
FileList result = drive.files().list().execute();

Authorization code
GoogleCredential credential = GoogleCredential.fromStream(new FileInputStream("resources/credentials.json"))

String folderId = "***DB-Drive id****";
File fileMetadata = new File();

fileMetadata.setParents(Collections.singletonList(folderId));
java.io.File filePath = new java.io.File("/home/*****/Downloads/qck_1552369371.jpeg");

I am setting DB-Drive which is the teamdrive or the shareddrive as the parent of the uploaded file but still I am not able to view this in the shared drive folder.. Please help me with this.
I am adding the complete flow :-
1.) I create the service account using the steps mentioned at https://developers.google.com/identity/protocols/oauth2/service-account
I selected the project and gave the description and everything.
2.) I did'nt gave domain level delegation to service account rather I shared the DB-drive(team drive) with service account address (which was mentioned in credentials.json file as client_email *****.gserviceaccount.com)
3.) Then I used the above code to upload the file asking service account to upload the file to shared drive i.e DB-Drive by specifying the DB-Drive's id as the parent id of the file.
4.) but still the file is getting uploaded to service account's drive it is not getting linked to shared drive.
5.) DB-Drive is the parent folder (the only folder).
Any leads would be a great help.

如 @ziganotschka 指出的,如果要在共享驱动器中创建文件,您需要将 supportsAllDrives
设置为 true。Java 客户端的 setSupportsTeamDrives
选项已被弃用。而是使用 setSupportsAllDrives
设置为 true。
当您在使用服务帐户将文件上传到共享驱动器时遇到问题,您应采取以下故障排除步骤:
- 隔离问题
- 自己问一下 - 问题是否与服务帐户的使用或其他事情有关?
- 为此,请尝试在没有服务帐户的情况下进行相同的请求
- 如果服务帐户被证明是问题的原因
- 验证您是否在 GCP 控制台中正确启用了域代表授权
- 验证您是否在管理控制台中为委派的服务帐户提供了正确的范围
- 验证您的代码实现是否正确
- 如果问题与服务帐户无关 - 验证是否与代码语法相关或与请求相关
- 为此,请使用尝试此 API工具,在不编码的情况下测试您的请求
- 如果问题与编码有关 - 调试您的代码
- 如果问题与请求有关,则根据尝试此 API返回的错误采取行动
- 如果收到
404 文件未找到
错误 - 这可能意味着- 文件位于共享驱动器上(在这种情况下,您必须将
supportsAllDrives
设置为true
,如上所述) - 或者 fileId 不正确
- 或者文件对您用于身份验证的帐户不可访问
- 文件位于共享驱动器上(在这种情况下,您必须将

As @ziganotschka points out you need to set supportsAllDrives
to true if creating a file in a shared drive. The Java client's setSupportsTeamDrives
option is deprecated. Instead use setSupportsAllDrives
to true.
When you have troubles uploading a file with a service ccount to a shared Drive, you should take the following steps for troubleshooting:
- Isolate the problem
- Ask yourself - is the problem related to the usage of the service account or something else?
- For this, test the same request without a service account
- If the service account turns out to be the culpit
- Verify that you enabled domain-wide delegation correctly in the GCP console
- Verify that you provided the correct scopes to the delegated service account in the Admin console
- Verify that your code implementation is correct
- If the problem is not service account related - verify either it is code syntax related or request related
- For this, use the Try this API tool to test your request without coding
- If the issue is coding related - debug your code
- If the issue is request related, act according to the error the Try this API returns you
- If you receive a
404 File not found
error - it either means that- the file is located on a shared Drive (in this case you have to set
supportsAllDrives
totrue
as mentioned above) - or the fileId is not correct
- Or the file is not accessible to the account you use for authentication
- the file is located on a shared Drive (in this case you have to set
