flask 通过url_for动态构建特定函数url

from flask import Flask, redirect, url_for
app = Flask(__name__)

@app.route('/admin')
def hello_admin():
return 'Hello Admin'

@app.route('/guest/<guest>')

def hello_guest(guest):
return 'Hello %s as Guest' % guest


@app.route('/user/<name>')
def hello_user(name):
if name =='admin':
return redirect(url_for('hello_admin'))
else:
return redirect(url_for('hello_guest',guest = name))


if __name__ == '__main__':
app.run(debug = True)

打开浏览器并输入URL - http://localhost:5000/user/admin
浏览器中的应用程序响应是：

Hello Admin

在浏览器中输入以下URL - http://localhost:5000/user/mvl
应用程序响应现在更改为：

Hello mvl as Guest
