EEException：服务器返回 HTTP 代码：404 --- 使用 Google App Engine 和 Google Earth Engine 测试应用

Question

我正在尝试使用带有 Google Earth Engine 应用程序的时尚灯光示例来测试带有 Google App Engine 的基本应用程序。

我从 GEE github 存储库中克隆了 Trendy-lights 应用程序，并更新了 app.yaml 中的应用程序名称、config.py 中的 EE_ACCOUNT 和 privatekey.pem 文件。我没有做任何其他改变。但是，时尚灯应用程序不起作用。

请查看我在下面得到的错误。我试图弄清楚为什么它不起作用。 （仅供参考，我在 GAE 中尝试了示例烧瓶应用程序，它运行良好，当我进入应用程序网页时，我看到了“Hello World”文本）。

有谁知道我得到的错误指的是什么？我没有头绪，也不知道如何调试它。

另一个问题：要使用 GAE 和 GEE 运行这个应用程序（即时尚灯示例），我是否必须注册 GAE 免费试用？ （我是 GEE 值得信赖的测试人员）

感谢您的帮助！

阿里

我在 Windows 8.1 上运行的 VirtualBox 上运行 osgeo Lubuntu。 （VirtualBox-5.0.0-101573-Win、osgeo-live-8.5、Python 2.7.6、Google App Engine 1.9.24）。

Answer 1

此问题中发布的问题现已解决。

Google Earth Engine 平台的管理员必须将我的服务帐户列入白名单，该应用才能运行。

Answer 2

正如here 发布的那样，您必须调用ee.Initialize() 以便earthengine api 搜索由命令earthengine authenticate 创建的身份验证文件。
