    判断请求是否成功,可以从返回的状态码来区别,所以当写接口的时候也要这样做,标准化.

    from rest_framework import status通过导入status,里面已经定义好了状态码,源码如下:

    """

    django rest framework 已经封装好了接口的类,通过导入from rest_framework.views import APIView,继承APIView类,APIView类会自动判断请求的方式,通过不同的请求(get,post)触发不同的方法,代码如下:

    from rest_framework.views import APIView
    from django.http import JsonResponse
    from rest_framework import status
    import hashlib
    import base64
    
    
    class CeShi(APIView):
        def dispatch(self, request, *args, **kwargs):
            """
            请求到来之后,都要执行dispatch方法,dispatch方法根据请求方式不同触发 get/post/方法
            """
            return super().dispatch(request, *args, **kwargs)
    
        def get(self, request):
            # get 请求
            key = self.get_token()
            token = request.GET.get('token')
            print(key)
            if key != token:
                return JsonResponse({'status': status.HTTP_401_UNAUTHORIZED, 'msg': 'Token error'}, status=status.HTTP_401_UNAUTHORIZED)
            return JsonResponse({'status': status.HTTP_200_OK, 'data': []}, status=status.HTTP_200_OK)
    
        def post(self, request):
            token = request.data.get('token')
            key = self.get_token()
            print(request.data)
            # 判断token是否正确
            if key != token:
                return JsonResponse({'status': status.HTTP_401_UNAUTHORIZED, 'msg': 'Token error'}, status=status.HTTP_401_UNAUTHORIZED)
            return JsonResponse({'status': status.HTTP_200_OK, 'data': []}, status=status.HTTP_200_OK)
    
        def get_token(self):
            """
            sha256+base64得到token
            :return: token
            """
            appkey = 'helloworld'
            # sha256加密
            s = hashlib.sha256(appkey.encode("utf-8")).hexdigest()
            # base64编码
            token = base64.b64encode(s.encode("utf-8")).decode('utf-8')
            return token


    postman截图效果: 可以看到http请求的状态码变成401,验证错误!

    请求成功截图: 请求状态码200
