使用oauth游乐场(java)上传到Google Drive不工作
我想用google drive api用java把一些文件上传到我的硬盘上 问题是上传成功了,但是当我打开我的驱动器时,我找不到文件,所以我编辑了权限并添加了我的电子邮件(与我共享),但我无法下载文件,只有上传的名称知道为什么吗
public static void connect() throws IOException, GeneralSecurityException {
UL.debug("Creating HTTP_TRANSPORT & a JSON_FACTORY");
HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
UL.debug("Login-in with credentials");
GoogleCredential credential = GoogleCredential.fromStream(new FileInputStream(CREDENTIALS_FILE))
.createScoped(Collections.singleton(DriveScopes.DRIVE));
UL.debug("User: " + credential.getServiceAccountUser() + " ID: " + credential.getServiceAccountProjectId());
UL.debug("Creating Drive Instance");
DRIVE_SERVICE = new Drive.Builder(
HTTP_TRANSPORT, JSON_FACTORY, credential)
.setApplicationName("Backup")
.build();
}
public static void upload() throws IOException {
UL.debug("Creating file metadata");
File fileMetadata = new File();
fileMetadata.setName("Test");
fileMetadata.setMimeType("application/rar");
UL.debug("creating new filepath");
java.io.File filePath = new java.io.File(DATA_FOLDER, "test3.rar");
UL.debug("Creating file content (rar)");
FileContent rarContent = new FileContent("application/rar", filePath);
UL.debug("Pushing the file to drive !");
Drive.Files.Create upload = DRIVE_SERVICE.files().create(fileMetadata, rarContent);
upload.getMediaHttpUploader().setProgressListener(new FileUploadProgressListener());
upload.setFields("*");
File e = upload.execute();
UL.debug("Push success: " + e.getId() + " " + e.getName() + " " + e.getMimeType());
Permission newPermission = new Permission();
newPermission.setEmailAddress("eaglezledozo@gmail.com");
newPermission.setType("user");
newPermission.setRole("writer");
DRIVE_SERVICE.permissions().create(e.getId(), newPermission).execute();
}

您正在使用服务帐户执行上载
按照你的方式,文件将被上传到服务的账户驱动器,而不是你的账户驱动器
如果你想用一个服务帐户执行上传,而这个服务帐户应该代表你(也就是把一个文件上传到你的驱动器),你需要使用impersonation
在java中,在构建
DRIVE_SERVICE
时,必须添加行.setServiceAccountId(emailAddress)
指定服务帐户应代表其行事的用户的电子邮件地址(在本例中为您的电子邮件地址)
