如何从AppEngine下载特定服务的源代码？

问题描述

我有一些php源代码在应用程序引擎生产环境中工作，无法在其他任何地方使用。该代码的旧版本似乎根本不起作用，因此我需要获取该源代码，并了解它的做法有何不同。

本讨论概述了我遇到的挑战：

我被告知尝试使用appcfg.py download_app：

  
从 appcfg.py download_app --help ：
这个调用允许我下载非默认python模块的代码：
 
 
  appcfg.py --module =< my_module> download_app -A< my_app> 。 
  
当然，您需要满足认证和所有权要求等
并且您的应用程序不应该被配置为防止源代码下载（可变配置） 
I have some php source code working in an app engine production environment that won't work anywhere else.  Old versions of that code don't seem to work at all either so I need to get that source and see what the heck it is doing differently.
This discussion outlines the challenges I'm having:http://google-app-engine.75637.x6.nabble.com/Download-specific-Module-code-td699.html
I was told to try using appcfg.py download_app:
appcfg.py download_app -A <APP_NAME> -V <Version> <DIR>
The problem is that this command does not allow me to specify module / service so I can't target my source code.  Also I'm not the App owner so I can't download everything but from what I understand that still wouldn't work because appcfg only seems to target the default service.
The article I linked ends with a suggestion to use gcloud to download the app but I haven't been able to find how to do that.  Does anyone here know how to resolve this?  The service is running in a Flexible instance - not sure if that makes a difference...
 解决方案 
From appcfg.py download_app --help:
This invocation allowed me to download the code for the non-default  python module of :
appcfg.py --module=<my_module> download_app -A <my_app> .
Of course, you need to meet authentication and ownership requirements, etc.And your app shouldn't have been configured for prevention of source code downloads (ireversible config)
