问题描述

任何人都知道在python中嵌入python的好方法吗？


现在在你告诉我'傻了之前，让我解释一下/>
我想做什么。


我想允许用户定义的可编写脚本的对象。我想要给他们修改我课程的部分。

我想禁止访问其他的

模块。


任何想法/例子？

Anyone know a good way to embed python within python?

Now before you tell me that''s silly, let me explain
what I''d like to do.

I''d like to allow user-defined scriptable objects. I''d
like to give them access to modify pieces of my classes.
I''d like to disallow access to pretty much the rest of
the modules.

Any ideas/examples?

推荐答案

你可能想要这样的东西：


globalDict = {}

exec（stringOfPythonCodeFromUser，globalDict）


globalDict现在是

stringOfPythonCodeFromUser中的任何内容的全局命名空间，因此您可以从中获取值并且选择性地导入

它们进入你的命名空间。

You probably want something like this:

globalDict = {}
exec(stringOfPythonCodeFromUser, globalDict)

globalDict is now the global namespace of whatever was in
stringOfPythonCodeFromUser, so you can grab values from that and
selectivly import them into your namespace.

在旧版本的b / b
版本的Python中有一个名为rexec / Bastion的功能，但由于它不安全而被删除了。

There was a feature called rexec/Bastion for that purposes in older
version of Python, but it was removed because it was insecure.
Any ideas/examples?

在一个单独的过程（或单独的计算机）中运行敏感的东西

并允许敌意客户通过套接字进行沟通。

Run your sensitive stuff in a separate process (or separate computer)
and allow the hostile clients to communicate through sockets.

globalDict现在是 stringOfPythonCodeFromUser，所以你可以从中获取值，然后选择性地将它们导入你的命名空间。


所以使用它（带一点额外的读数）它看起来像我

可以做到这一点：


globalDict = {''__ builtin__''：< my modules here>}

exec（< pythonCodeFromUser>，globalDict）


这将禁止导入新模块并直接访问我的命名空间。然而它将允许访问


这是否安全？


保罗，您对此有何看法？

So using this (with a little additional reading) it looks like I
can do this:

globalDict = {''__builtins__'': <my modules here>}
exec(<pythonCodeFromUser>, globalDict)

And that this will disallow both importing of new modules and direct
access to my namespace. It will however allow access to the

Would this be secure?

Paul, what''s your take on this?
