Django:如何在每次请求时创建和调用构造函数?

POST

所以我想要的代码是:

import validator

class ViewClass():
    def __CONSTRUCTOR__(self, request):
        is_valid = validator.validate()
        if is_valid == FALSE
           return HttpResponse('Request is Invalid')

    def request_function_one(request):
        if request.method == 'POST':
            return HttpResponse('Request 1 is Valid')

    def request_function_two(request):
        if request.method == 'POST':
            return HttpResponse('Request 2 is Valid')
