Question

当用户提交输入时，我尝试执行将用户输入作为参数的脚本，并将用户重定向回主页。当我运行下面的脚本时，除了重定向之外，一切似乎都有效。当我在网络浏览器中点击提交时，我收到了无数据提交。

from flask import Flask, render_template, redirect, request
from Index_generator import index_generator
from Yelp_api import request_yelp

@app.route('/home_city',methods = ['POST'])
def home_city():
    CITY=request.form['city']
    request_yelp(DEFAULT_LOCATION=CITY) #This function executes the script
    return redirect('/')

如果将url_for与redirect一起使用，该怎么办？

from flask import Flask, render_template, redirect, request, url_for
from Index_generator import index_generator
from Yelp_api import request_yelp

@app.route('/', methods = ['GET'])
def home():
    return 'Hello World'

@app.route('/home_city',methods = ['POST'])
def home_city():
    CITY=request.form['city']
    request_yelp(DEFAULT_LOCATION=CITY) #This function executes the script
    return redirect(url_for('home'))

Flask：用户输入[POST]
