关于视图

1 为路由起名

通过endpoint参数为路由起名

  1. api.add_resource(HelloWorldResource, '/', endpoint='HelloWorld')

2 蓝图中使用

  1. from flask import Flask, Blueprint
  2. from flask_restful import Api, Resource
  3. app = Flask(__name__)
  4. user_bp = Blueprint('user', __name__)
  5. user_api = Api(user_bp)
  6. class UserProfileResource(Resource):
  7.     def get(self):
  8.         return {'msg': 'get user profile'}
  9. user_api.add_resource(UserProfileResource, '/users/profile')
  10. app.register_blueprint(user_bp)

3 装饰器

使用method_decorators添加装饰器

  • 为类视图中的所有方法添加装饰器

    1. def decorator1(func):
    2.     def wrapper(*args, **kwargs):
    3.         print('decorator1')
    4.         return func(*args, **kwargs)
    5.     return wrapper
    6. def decorator2(func):
    7.     def wrapper(*args, **kwargs):
    8.         print('decorator2')
    9.         return func(*args, **kwargs)
    10.     return wrapper
    11. class DemoResource(Resource):
    12.     method_decorators = [decorator1, decorator2]
    13.     def get(self):
    14.         return {'msg': 'get view'}
    15.     def post(self):
    16.         return {'msg': 'post view'}

  • 为类视图中不同的方法添加不同的装饰器

    1. class DemoResource(Resource):
    2.     method_decorators = {
    3.         'get': [decorator1, decorator2],
    4.         'post': [decorator1]
    5.     }
    6.     # 使用了decorator1 decorator2两个装饰器
    7.     def get(self):
    8.         return {'msg': 'get view'}
    9.     # 使用了decorator1 装饰器
    10.     def post(self):
    11.         return {'msg': 'post view'}
    12.     # 未使用装饰器
    13.     def put(self):
    14.         return {'msg': 'put view'}
