How to run a python script on flask backend?
提问by Jason Stein
I have a small flask app where it takes user input and returns some text. Here the user input is fed to another python script say temp.py and this temp.py will return a value which should be returned to user. For eg:
我有一个小烧瓶应用程序，它接受用户输入并返回一些文本。在这里，用户输入被馈送到另一个 python 脚本中，比如 temp.py，这个 temp.py 将返回一个应该返回给用户的值。例如：
flask.py
烧瓶.py
from flask import Flask, render_template, request
app = Flask(__name__)
@app.route('/')
def result():
return render_template("index.html")
@app.route('/getconfig', methods=['GET', 'POST'])
def config():
value = request.form['config']
print ("This is the user value : ", value);
// This value is written to a file say x.pol and my temp.py reads from x.pol file and writes the output to y.pol. I'm not sure how to trigger the script like "python temp.py" on the server.
// The reason I'm doing this because I don't want to tweak the third party tool where, the third party tool reads from input files and generates output files.
return content_generated_by_temp.py // by reading y.pol.
if __name__ == '__main__':
app.run(debug = True)
By the way, temp.py is itself a nightmare. I understood what the tool does. For more info about the tool: Google Caprica
顺便说一下，temp.py 本身就是一场噩梦。我了解该工具的作用。有关该工具的更多信息：Google Caprica

Wrap whatever temp.pyis doing in a function. Place it in the same directory as flask.py. Call import tempin flask.py, then use temp.myfunction()
将temp.py正在执行的操作包装在一个函数中。将其放在与flask.py. 通话import temp中flask.py，然后使用temp.myfunction()
