Question

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

app = Flask(__name__)

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

@app.route('/graph', methods=['POST'])
def graph():
    fchoice = request.form['user']
    schoice = request.form['password']
    return choice + " " + choice

这是index.html中的html：

<form action="/graph" method="post">
    <input type="text" placeholder="first choice" name="user" disabled id="chose">
    <input type="text" placeholder="second choice" name="password" disabled id="chose1">

    <input type="submit" value="Vote">
</form>

Answer 1

您正在尝试连接未定义的变量。

return choice + " " + choice

你没有choice。您有fchoice和schoice。

@app.route('/graph', methods=['POST'])
def graph():
    fchoice = request.form['user']
    schoice = request.form['password']
    return fchoice + " " + schoice
