如何列出静态目录中的文件？ [英] How to list the files in a static directory?

问题描述

我正在使用Google App Engine和Python，但无法列出静态目录的文件。以下是我目前使用的代码。

app.yaml

   -  url：/ data 
 static_dir：data 
  

Python代码列出文件

  myFiles = [] 
 for root，dirs，files in os.path（os.path.join（os.path.dirname（__ file__），'data /'））：
用于文件中的名称：
 full_name = os.path.join（root，name ）
 myFiles.append（'％s;％s\\\
'％（name，datetime.fromtimestamp（os.stat（full_name）.st_mtime）））
  

当我在本地机器上运行此代码时，一切都可以。我在目录的根目录下有我的Python脚本，它将数据目录下的文件遍历。但是，当我上传并在GAE中运行完全相同的代码时，它不起作用。在我看来，我的应用程序的目录结构并未在Google App Engine中完全复制。 静态文件在哪里？

谢谢！

它们不在你认为的位置，GAE会将静态内容放入GoogleFS，相当于CDN。这个想法是，静态内容意味着直接提供给您的用户，而不是您可以操作的文件存储。此外，GAE有1K文件限制，如果你可以操纵你的静态文件存储，那么很难监管这条规则。

I am playing with Google App Engine and Python and I cannot list the files of a static directory. Below is the code I currently use.

app.yaml

- url: /data
  static_dir: data

Python code to list the files

myFiles = []
for root, dirs, files in os.walk(os.path.join(os.path.dirname(__file__), 'data/') ):
    for name in files:
        full_name = os.path.join(root, name)
        myFiles.append('%s;%s\n' % (name, datetime.fromtimestamp(os.stat(full_name).st_mtime)))

When I run this code locally on my machine, everything is alright. I have my Python script at the root of the directory and it walks the files under the data directory. However, when I upload and run the exact same code in GAE, it doesn`t work. It seems to me that the directory structure of my application is not exactly replicated in Google App Engine. Where are the static files?

Thanks!

They're not where you think they are, GAE puts static content into GoogleFS which is equivalent of a CDN. The idea is that static content is meant to be served directly to your users and not act as a file store you can manipulate. Furthermore GAE has 1K file limit and it would be difficult to police this rule if you could manipulate your static file store.
