GAE-适用于静态页面和Python的app.yaml

Question

I am trying to create a static html component (that will be usable offline) for a Google App that is otherwise Python.

I can't seem to get the app.yaml file configured correctly for that.

handlers:

  # Serve images and JSON as static resources.
- url: /(.+\.(gif|png|jpg|json|ico))$
  static_files: \1
  upload: .+\.(gif|png|jpg|json|ico)$
  application_readable: true

- url: \/(static)\/(index)\.html
  static_files: static/\1/index.html
  upload: static\/index.html

- url: /
  script: roomusage.app
  login: required
  secure: always

- url: /welcome
  script: roomusage.app
  login: required
  secure: always

- url: /record
  script: record_usage.app
  login: required
  secure: always

Here's the error message I'm getting:

appcfg.py: error: Error parsing C:\gcloud\dev-myapp\app.yaml: Unable to assign value '\/(static)\/(index)\.html' to attribute 'url':
Value '\/(static)\/(index)\.html' for url does not match expression '^(?:(?!\^)/.*|\..*|(\(.).*(?!\$).)$'
  in "C:\gcloud\dev-myapp\app.yaml", line 25, column 8.

Answer 1

Your \\/(static)\\/(index)\\.html pattern is an invalid URL regex pattern.

First - the pattern can't start with \\ - you don't need to escape / .

The round paranthesis in the pattern are used to identify positional groupings which can then be referred to as parameters by \\1 , \\2 , etc in subsequent statements, like static_files , for example. From the url row in the Handlers elements table:

url

Required element under handlers . The URL pattern, as a regular expression. The expression can contain groupings that can be referred to in the file path to the script with regular expression back-references. For example, /profile/(. )/(. ) would match the URL /profile/edit/manager and use edit and manager as the first and second groupings.

If you don't need such grouping/parameters then don't use the round paranthesis in your patterns. So to match just /static/index.html you could have:

- url: /static/index\.html
  static_files: static/index.html
  upload: static/index.html

But you should note that the above is redundant if you also have:

- url: /static
  static_dir: static
