尝试到达应用引擎端点时出现 SSLHandshakeException

Question

我正在尝试从 android 客户端连接到我的端点方法之一到我的本地运行应用引擎后端。问题是我遇到了 SSLHandshakeException。我的 API 不受 OAuth 保护。我尝试达到的方法如下所示：

@ApiMethod(name = "register")
public UserInfo registerUser(UserInfo userInfo) {
    try {
        checkUserParameters(userInfo);
        ofy().save().entity(userInfo).now();
        return ofy().load().entity(userInfo).now();
    } catch (InvalidPropertiesFormatException e) {
        logger.info(e.getMessage());
        return null;
    }
}

从我的客户那里我这样做：

  if (regService == null) {
            UserInfoApi.Builder builder = new UserInfoApi.Builder(AndroidHttp.newCompatibleTransport(),
                   new AndroidJsonFactory(), null)
                .setRootUrl(LoginActivity.LOCALHOST_IP)
                .setGoogleClientRequestInitializer(new GoogleClientRequestInitializer() {
                    @Override
                    public void initialize(AbstractGoogleClientRequest<?> abstractGoogleClientRequest)
                            throws IOException {
                        abstractGoogleClientRequest.setDisableGZipContent(true);
                    }
           });

           regService = builder.build();
           UserInfo userInfo = new UserInfo();
           userInfo.setGcmId(registerToGcm());
           userInfo.setAccountName(params[0]);
           userInfo.setEmail(params[0]);
           userInfo.setProfilePictureUrl(null);
           UserInfo userInfo = regService.register(userInfo).execute();
  }

出于某种原因，这不起作用，我也尝试过将后端模块导入 android studio 时得到的 API，但它给出了相同的错误。

所以...问题是我在客户端上设置 rootUrl 时使用的是 https 而不是 http。
