将来自HTML表单的用户输入作为Python脚本的变量 [英] Taking user input from HTML form as a variable for Python script

问题描述

我正在Python/Flask中创建一个Web应用程序，以通过使用tweepy的twitters API显示推文.我已经建立了HTML表单，并获得了使用特定输入查找推文的脚本，目前，这是硬编码的.我希望用户输入主题标签或类似标签，然后在提交时运行脚本，并将其作为参数

I'm creating a web app in Python/Flask to display tweets using twitters API using tweepy. I have set up an HTML form, and have got the script that finds the tweets with a certain input, currently, this is hard coded. I want the users to input a hashtag or similar, and then on submit, the script to run, with that as its parameter

我已经创建了一个表单，其中包含GET方法，并且操作是要运行脚本.

I've created a form, with method GET and action is to run the script.

<form class="userinput" method="GET" action="Tweepy.py">
    <input type="text" placeholder="Search..">
    <button type="submit"></button>
</form>

我不知道如何获取用户输入并将其存储在变量中以用于扭曲代码，将不胜感激

I dont know how I would get the users input and store it in a variable to use for the tweepy code, any help would be greatly appreciated

推荐答案

templates/index.html

<form method="POST">
    <input name="variable">
    <input type="submit">
</form>

app.py

from flask import Flask, request, render_template
app = Flask(__name__)

@app.route('/')
def my_form():
    return render_template('index.html')

@app.route('/', methods=['POST'])
def my_form_post():
    variable = request.form['variable']
    return variable
