[Flask] url_for

from flask import Flask, url_for

app = Flask(__name__)

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

@app.route('/login')
def login():
    return 'login'

@app.route('/user/<username>')
def profile(username):
    return '{}\'s profile'.format(username)

with app.test_request_context():
    print(url_for('index'))
    print(url_for('login'))
    print(url_for('login', next='/'))
    print(url_for('profile', username='John Doe'))

/
/login
/login?next=/
/user/John%20Doe

그냥 함수와 인자를 넣어주면 그에 맞는 url을 반환하는 것 같다.
