# 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()
