我遇到了一个奇怪的问题,正在寻找解决方案,但到目前为止,它似乎是独一无二的

我的问题是,在GAE中使用localhost运行应用程序时,我的静态文件(css、模板、javascript等)没有加载。然而,当我将应用程序部署到GAE服务器(appspot)上时,这些静态文件运行得非常好

这甚至发生在GAE文档中的默认留言簿应用程序中

我正在Windows上使用GAE launcher(Python)1.9.6。Python是64位版本,2.7.7。已经确保GAE指向python的正确位置

到目前为止,我在每个应用程序中都遇到了这个问题,所以我怀疑这是代码的问题。但是,以下代码供您参考:

谢谢大家!

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

见以下最近的问题:

请在GAE错误跟踪器中报告。

请更换:

- url: /stylesheets
  static_dir: stylesheets
与:


如果您的
静态
文件夹不在您的根目录中,而是在另一个文件夹中,例如
应用程序
(如我的情况),您需要将其包括在您的
应用程序中。yaml

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

我看不出有错。但是您可以使用它进行测试:1)您可以键入静态目录资源的url来获取静态文件。2) 您可以使用chrome调试器查看请求、响应和错误。
- url: /stylesheets
  static_dir: stylesheets
- url: /(.*\.css)
  static_files: static/\1
  upload: static/.*\.css
- url: /app/static
  static_dir: static
  secure: always
