使用URL传递参数

1、传递普通参数

@app.route('/article/<aid>/')
def article(aid):
    return aid

2、传递指定类型的参数

@app.route('/article/<path:aid>/')
def article(aid):
    return aid


# uuid：2062b250-4b97-11ec-a0d1-a0fa6f178116
@app.route('/article/<uuid:aid>/')
def article(aid):
    return aid


@app.route('/<any(article,news):url>/')
def article(url):
    return 'same page'

3、传递查询参数

@app.route('/article/')
def item():
    aid = request.args.get('aid')
    return aid
