燒瓶：用戶輸入[POST]

Question

當用戶提交輸入時，我試圖執行一個腳本，將用戶輸入作爲參數並將用戶重定向回主頁。當我運行下面的腳本時，一切似乎都適用於重定向的例外。當我點擊網頁瀏覽器提交時，我收到沒有數據提交。

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('/') 

Answer 1

如果使用url_for和redirect怎麼辦？

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'))
