app.py文件--------创建项目、设置路由、启动项目

from app.num_check import num_check
#添加路由接口
api.add_resource(num_check, "/num_check/LV/check_test/")

num_check.py------利用Resource模板设置get请求的响应信息

from flask_restful import Resource

        time.sleep(3)
        t = current_app.executor.submit(num_check_load, num)
        check_info = t.result()
