Question

我正在尝试将Web表单的内容放到python脚本中。我使用下面的代码，当我点击提交时，我必须在网页上看到输出。基本上你好，（取自网页作为输入）。我遇到了类型错误。

#!/bin/python

import os

from flask import Flask
from flask import request
from flask import render_template

app = Flask(__name__)

@app.route('/')

def my_form():
    return render_template("index.html")

@app.route('/', methods=['POST'])

def my_form_post():
    text = request.form['text']
    cmd = "sh relay.sh " + text
    rep = os.system(cmd)
    return rep

if __name__ == '__main__':
    app.run()

运行时出现以下错误。我基本上试图从网页（文本框）传递一些信息。我刚刚进入了Damnnn＆＃39;检查输出。

TypeError: 'int' object is not callable

对不起，我是python的新手。

你要返回的对象是一个int，试着像这样强制转换为字符串。

return str(rep)

当我返回Python程序的变量时出现TypeError错误
