标记未在Google App Engine中显示在Google地图上

Question

我在Python中创建了一个Google App Engine项目,它在我的localhost上运行但是当我将它上传到geo-event-maps.appspot.com时,标记没有显示.我有一个cron,它可以调用/放置.我没有日志错误我的数据存储空了!正在上传txt文件:

    file_path = os.path.dirname(__file__)
    path = os.path.join(file_path, 'storing', 'txtFiles')

有没有办法检查文件是否已上传？!

我绝对亏损.以前有没有人遇到过这些问题？

下面是我的main.py:

    wsgiref.handlers.CGIHandler().run(application)


if __name__ == '__main__':
    main()

这是我的cron.yaml

    cron:
- description: running place
  url: /place
  schedule: every day 11:05

App.yaml如下:

application: geo-event-maps
version: 2
runtime: python
api_version: 1

handlers:
- url: .*
  script: main.py
builtins:
- datastore_admin: on

您需要确保您的文件是与您的应用程序代码一起上传的，它们不能被标记为静态文件，否​​则您的代码将无法访问它们。使用该--verbose标志运行 appcfg.py 并确保它们已上传。

第二个问题，在您的place班级中您将路径定义为path = '/storing/txtFiles'。那是错的。你的路径可能更像是：

file_path = os.path.dirname(__file__)
path = os.path.join(file_path, 'storing', 'txtFiles')

另外，我建议你不要使用print，而是使用self.response.out.write(stuff_to_write).

您可能还想了解如何使用 key_names。通过在嵌套 for 循环内运行批处理 db.get 而不是 db.Query，您将能够使代码更加高效。使用Appstats并尝试最小化 RPC 的数量。
