flask - 定义API接口

flask自行定义API接口,并且可以实现接口调试的增删查改

  1. 需要两个工具

    pip install flask_restful
    pip install flask_marshmallow

  2. 初始化app:

    初始化app的两种方式:
    Api(app=app)
    或者
    api = Api()
    api.init__app(app)

    from flask_restful import Api
        from flask_marshmallow import Marshmallow
    
        api = Api()
        ma = Marshmallow()
    
        api.init_app(app)
        ma.init__app(app)
  3. 显示内容:

    views.py文件中:

    from flask_restful import Resourse
            from utils.function import api
    
            class HelloStudent(Resourse):
    
            显示内容:方式1:
            def get(self, id):
    
            stu = Student.query.get(id)
            data = {
                'name': stu.s_name,
                'age': stu.s_age
            }
            return data
    
            # 显示内容方式2:
            首先同级目录下新建StuMarshmallow.py文件:
            from utils.function import ma
    
            class StuMarsh(ma.Schema):
    
            class Meta:
    
                fields = ('s_name', 's_age') 定义要 展示的对象的内容
    
            stumarsh = StuMarsh()
    
    
            from Stu.StuMarshmallow import stumarsh
            def get(self, id):
    
            stu = Student.query.get(id)
    
            return stumarsh.jsonify(stu)
    
            def post(self, id):
                pass
    
            def patch(self, id):
                pass
    
            def put(self, id):
                pass
    
            def delete(self, id):
                pass

    上面定义的是借口访问的方式,postman中不同的请求方式,返回上面对应的不同方法

  4. 定义api接口访问的url:

    api.add_resourse(HelloStudent, '/api/hello/<int:id>/')
    
    示例: 127.0.0.1:8000/api/hello/3/
