java Google Drive API:共享文件夹时出错500

Question

我使用谷歌教育应用程序为学生和教职员工创建和共享文件夹。 这是使用服务器端流完成的，因为我们可能需要增加存储。 当共享一些文件夹时，它是有效的，但当共享其他文件夹时，我会得到内部错误500。 有时这种情况会发生在绝大多数文件夹中，但很少发生在所有文件夹中

例如，我为大约1000个用户创建了文件夹，但每次共享都失败了。 它们与type=user、role=writer共享

而且，就像今天发生的那样，有时候分享不会导致任何错误，而我 可以为所有用户创建和共享文件夹

有人有什么想法吗？ 谢谢 迈克尔

我这样称呼shareFolder： 共享文件夹（，“用户”，“作者”，真）

public boolean shareFolder(String fileId, String sharerEmail, String type, String role, boolean forcesharing) {

    if (sharerEmail == null || sharerEmail.length() == 0) {
        return true;
    }

    sharerEmail = sharerEmail.toLowerCase();
    Permission perm = sharedAlready(fileId, sharerEmail, type, role);

    if (forcesharing && perm == null) {
        logger.info("File id " + fileId + " will be force shared with " + sharerEmail + ".");
        Permission permission = new Permission();
        permission.setValue(sharerEmail);
        permission.setEmailAddress(sharerEmail);
        permission.setType(type);
        permission.setRole(role);

        return insertSharingperm(fileId, permission);
    } else if (forcesharing) {
        // I do this in the hope that it my have an effect, but I'm beginning to doubt it.
        // There seems to be a problem with sharing the class folders with the class email, as readers.
        return updateSharingperm(fileId, perm);
    } else {
        if (perm != null) {
            logger.info("File " + fileId + " already shared with " + sharerEmail + ".");
            return true;
        } else {
            Permission permission = new Permission();
            permission.setValue(sharerEmail);
            permission.setEmailAddress(sharerEmail);
            permission.setType(type);
            permission.setRole(role);

            return insertSharingperm(fileId, permission);
        }
    }
}



public boolean insertSharingperm(String fileId, Permission perm) {
    try {
        if (null != executeWithEB(service.permissions().insert(fileId, perm))) {
            logger.info("File id " + fileId + " shared with " + perm.getEmailAddress() + ".");
            return true;
        } else {
            logger.warning("File id " + fileId + " not shared with " + perm.getEmailAddress() + ".");
            return false;
        }

    } catch (GoogleJsonResponseException e) {
        logger.severe("Failed. Code: "
                + e.getDetails().getCode() + "\nMessage: "
                + e.getDetails().getMessage() + " FileID=" + fileId
                + " SharerEmail=" + perm.getEmailAddress() + " Type=" + perm.getType()
                + " Role=" + perm.getRole());
    } catch (IOException e) {
        logger.severe("Failed:" + e.getMessage());
    } catch (InterruptedException e) {
        logger.severe("Failed:" + e.getMessage());
    }

    return false;
