使用Web服务器上的参数运行python脚本的最简单方法

Question

Thought this would be straightforward, but it's giving me a lot of trouble. What's the simplest way to run a python script with params on a web server? I've tried Node, but had a lot of trouble with spawning child processes, tried PHP but ran into a similar problem and just couldn't get exec to work for even the simplest script. Just spent a while trying Django, but that turned out to be far too involved. How can I do this without re-inventing the wheel?

For example, take the following request:

www.example.com/someprogram?foo=bar&bar=baz

And render the output from a script run with those params:

python someprogram.py foo bar

Answer 1

Try bottle , a micro web framework:

someprogram.py:

def f(foo, bar):
    return "foo: {}, bar: {}"format(foo, bar)

server.py:

from bottle import route, run
import someprogram


@route('/')
def home():
    return someprogram.f(request.query.foo, request.query.bar)

if __name__ == "__main__":
    run(debug=True, reloader=True)

To run:

pip install bottle
python server.py

Use subprocess.check_output() to spawn a process if you don't want to import someprogram.py .
