app.yaml /项目文件结构适用于app引擎localhost调试器，但不适用于谷歌应用引擎服务器

Question

This issue is probably a result of my limited understanding of project structures in Python and app engine as well as my limited understanding of the app.yaml file.

I have a python 2.7 project who's file structure looks like this:

Project_name
 > src
   app.yaml
   > python
     __init__.py
     > package_folder1
       __init__.py
       package1_file.py
     > package_folder2
       __init__.py

My app.yaml file has this in it:

- url: /package1/resource1
  script: package_folder1.package1_file1.py
  secure: always

This works fine when debugging on localhost using app engine's simulator, but on the server, I am getting this warning (which in this case is an error because the script is not being served) when I try to access the resource /package1/resource1 :

File referenced by handler not found: python.package_folder1.package1_file1.py

I also tried changing the line in the app.yaml file to this script: package_folder1.package1_file1.py and still got the same error.

Any ideas? Thanks!

Answer 1

What runtime are you using python 2.5 or python 2.7? There are some differences when using one or the other. Also, where in your project structure are you storing the app.yaml file?

For python 2.5 you specify the actual python script, but for python 2.7 you specify the WSGI application. See https://developers.google.com/appengine/docs/python/config/appconfig#Script_Handlers for more details.

The runtime is defined in the app.yaml file with the key runtime.

runtime: python   #python 2.5
runtime: python27 #python 2.7

Answer 2

Is the python folder the entire python runtime? If so, you should not be including that.

Project_name
> src
  app.yaml
  > package_folder1
    __init__.py
    package1_file.py
  > package_folder2
    __init__.py

Use slashes instead of periods to specify the script in the app.yaml file:

script: package_folder1/package1_file1.py
