Flask restful Api基于蓝图,实现解耦

安装flask-restful
from flask import Flask
from flask_restful import Resource, Api

app = Flask(__name__)
api = Api(app) //封装app


class HelloWorld(Resource):
    def get(self,todo_id):
        return {"name":"alex"}

　　def put(self,todo_id):
　　　　pass

api.add_resource(HelloWorld,'/<string:todo_id>') //路由,资源和url建立映射关系
一种资源只能添加一次,#url匹配到http://127.0.0.1:5000/todo.?  

if __name__ == "__main__": app.run(debug=True,host="0.0.0.0")


#基于蓝图实现,目录结构如下

 

 

#run.py
from flask import Flask
from views import user_bp

app = Flask(__name__)
#
app.register_blueprint(user_bp.user_bp)
# # app.register_blueprint(order_bp)
#
if __name__ == "__main__":
    app.run()

#user_bp.py
from flask import Blueprint
from flask_restplus import Api,Resource, fields
#创建蓝图对象,解耦不同业务的接口
user_bp = Blueprint("user",__name__,url_prefix="/user") #user参数,用于url_for翻转使用,url_prefix用于区分不同的蓝图路由
# print(url_for("user.printf")) 没有endpoint,默认是函数名
api = Api(user_bp)
# 数据校验格式
tu_info = api.model("tuInfo",{
    "tuName": fields.String(required=True,description="测试项名称", enum=["Demo"]),
    "uuid": fields.Raw(required=True,description="自定义对象")
})

cloud_ate_base = api.model("cloudAteBase",{
    "version": fields.String(required=True, description="版本信息", enum=["v1.0.0.0"]),
    "tuinfo": fields.Nested(tu_info,required=True,description="测试项信息")
})

comrst = api.model("Commonresult",{
    "result": fields.Boolean(required=True, description="返回值=[True, False]"),
    "value": fields.Raw(required=True,description="返回结果=[string,list,dict]"),
    "info": fields.Raw(required=True, description="失败错误原因")
})

ns = api.namespace("Version", description="版本")

#使用API进行restful风格
@api.route("/index","/nomal") #支持多个路由指向同一资源
class Demo(Resource):
    #数据校验
    # @ns.expect(cloud_ate_base)
    @ns.marshal_with(comrst)
    def get(self):
        "逻辑处理"
        return {"result": True, "value": "测试结果", "info": "todo "}#返回结果进行marshal_with处理(字段类型一直)
