Question

我遇到了一个奇怪的问题，寻找解决方案，但到目前为止，它看起来很独特。

我的问题是，当我在GAE中使用localhost运行应用程序时，我的静态文件（css，templates，javascript等）无法加载。但是，当我将应用程序部署到GAE服务器（appspot）时，这些静态文件运行得非常好！

这甚至适用于GAE文档中的默认留言簿应用。

我在Windows上使用GAE启动程序（Python）1.9.6。 Python是64位版本，2.7.7。已经确定GAE指向python的正确位置。

到目前为止，我遇到了每个应用程序的这个问题，所以我怀疑这是代码的问题。但是，这是您的参考代码：

# saying "# AUTOGENERATED").  If you want to manage some indexes
# manually, move them above the marker line.  The index.yaml file is
# automatically uploaded to the admin console when you next deploy
# your application using appcfg.py.

在子文件夹“stylesheets”中，main.css

谢谢！

Answer 1

请替换：

- url: /stylesheets
  static_dir: stylesheets

使用：

- url: /(.*\.css)
  static_files: static/\1
  upload: static/.*\.css

希望它对你有用，就像它适合我一样

Answer 2

我认为这是GAE for Windows中的一个错误，在猜测静态文件的mimetype时，会将标头中的mimetype设置为python unicode字符串，在静态文件处理程序中抛出500错误。 / p>

请参阅以下最近的问题：

Google App Engine: Won't serve static assets with below error:

CSS Files not working on localhost

请在GAE错误跟踪器中报告。

Answer 3

如果您的static文件夹不在根目录中，而是在另一个文件夹中，例如app（以我为例），您需要将其包括在app.yaml中：

- url: /app/static
  static_dir: static
  secure: always

GAE Python：静态文件未在localhost中加载，但在将app部署到appspot时加载完全正常
