2. Flask
flask主要使用装饰器将URL和application联系起来,如@app.route('/', methods=['GET', 'POST'])
Flask也是基于WSGI的,进一步进行封装.
from flask import Flask from flask import request app = Flask(__name__) @app.route('/', methods=['GET', 'POST']) def home(): return 'at home' @app.route('/signin', methods=['GET']) def sigin_form(): return 'input x-auth-user and x-auth-pass' @app.route('/signin', methods=['POST']) def signin_auth(): username = request.headers.get('x-auth-user') passwd = request.headers.get('x-auth-pass') if username == 'coral' and passwd == '123': return 'success\nx-auth-user: %s and x-auth-pass: %s' %(username, passwd) else: return 'failed\nx-auth-user: %s and x-auth-pass: %s' %(username, passwd) if __name__ == '__main__': app.run()
