使用自定义的状态码检测前端传空值的方法

from sanic.exceptions import SanicException, add_status_code
# 自定义状态码
@add_status_code(7416)
class Attribute(SanicException):
    pass
 
# 定义一个类来判断前端传的值是否为空
class httpnew(HTTPMethodView):
    def getparms(self, request, *args, **kwargs):
        try:
            return request.json.get(*args, **kwargs).strip()
        except AttributeError as e:
            raise Attribute('sasadadad')
 
# 从教师APP过来通过手机号码获取教师MID
class GetTeacherMID(httpnew):
    # @jwtauth
    async def post(self, request):
        TeacherCode = self.getparms(request, "TeacherCode", "")
