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)
