95 - 在Flask中如何使用动态路由

1. 静态路由和动态路由有什么区别？

• 路由
  • Utl Path
  • http://loaclhost/abc/test.html
• 静态路由
  • Path与路由函数一一对应
• 动态路由
  • 多个Path与同一个路由函数对应
  • http://loaclhost/abc/test.html
  • http://loaclhost/xyz/test.html
  • 不管访问哪一个Url，都会执行同一个服务端的路由函数

2. 如何使用Flask实现动态路由

'''
pip install flack
'''

from flask import Flask
app = Flask('__name__')

# 静态路由
@app.route('/')
def index():
    return '<h1>root</h1>'

@app.route('/greet')
def greet():
    return '<h1>Hello everyone</h1>'

@app.route('/greet/bill')
def greetBill():
    return '<h1>你好 Bill</h1>'

# 动态路由
@app.route('/greet/<name>')
def greetName(name):
    return '<h1>Hello {}</h1>'.format(name)

'''
如果静态路由和动态路由有冲突，优先使用静态路由
'''

@app.route('/greet/<a1>/<a2>/<a3>')
def args1(a1, a2, a3):
    return '<h1>{},{},{}</h1>'.format(a1, a2, a3)

@app.route('/greet/<a1>-<a2>-<a3>')
def args2(a1, a2, a3):
    return '<h1>{}*{}*{}</h1>'.format(a1, a2, a3)

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