我正在使用Flask建立一個網站，我遇到了一個問題，在創建一個賬戶后，網站并沒有將我重定向到主頁上。
main.py
from Flask import Flask, render_template, url_for, flash, redirect
from forms import RegistrationForm, LoginForm
app = Flask(__name__)
帖子 = [
{
'author': 'Corey',
'title': 'blg post',
'content': 'first post',
'date_posted': 'april 20 2021'。
},
{
'author': 'Hus',
'title': '2nd post',
'content': '2nd post',
'date_posted': 'May 20 2021'.
}
]
@app.route("/"))
@app.route("/home")>
def home（）。
return render_template('home.html'/span>, posts=posts)
@app.route("/about")
def about() 。
return render_template('about.html', title='關于')
@app.route("/register", methods=['GET', 'POST')>
def register():
form = RegistrationForm()
if form.validate_on_submit（）。
flash(f'Account Created for {form.username.data}!', 'success')
return redirect(url_for('home'))
return render_template('register.html', title='注冊', form=form)
@app.route("/login")
def login（）。
form = LoginForm()
return render_template('login.html', title ='login', form=form)
if __name__ == '__main __':
app.run(debug=True)
form page
from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmissionField, BooleanField
from wtforms.validators import DataRequired, Length, Email, EqualTo
class RegistrationForm（FlaskForm）。
username = StringField('用戶名',
validators=[DataRequired(), Length(min=3, max=20) ])
email = StringField('Email', validators=[DataRequired(), Email()] )
password = PasswordField('密碼', validators=[DataRequired()])
confirm_password = PasswordField('Confirm Password', validators=[DataRequired(), EqualTo('password')])
submit = SubmitField('Sign Up')
class LoginForm（FlaskForm）。
email = StringField('Email', validators=[DataRequired(), Email()] )
password = PasswordField('密碼'/span>, validators=[DataRequired()])
remember = BooleanField('記住我',)
submit = SubmitField('Login')
html中的注冊頁面
{% extends "layout.html"%}{% block content %}.
{% block content %}

在點擊注冊頁面的注冊按鈕后，該頁面將我重定向到同一頁面，而不是主頁。
