django rest_framework 权限

在视图里面去设置权限

class OrderView(APIView):
    authentication_classes = [MyAuthtication]

    def get(self, request, *args, **kwargs):
        ret = {"state_code": 1000, "msg": "数据请求成功", "data": ORDER_DICT}
        if request.user.user_type != 3:
            ret = {"state_code": 1001, "msg": "无权限", "data": []}

        return JsonResponse(ret)

• postman校验

基本使用

class MyPermission(object):

    def has_permission(self,request,view):
        if request.user.user_type != 3:
            return False
        return True
                                            
            
class OrderView(APIView):
    """
    订单相关业务(只有SVIP用户有权限)
    """
    permission_classes = [MyPermission,]
                    
    def get(self,request,*args,**kwargs):
        # request.user
        # request.auth
        self.dispatch
        ret = {'code':1000,'msg':None,'data':None}
        try:
            ret['data'] = ORDER_DICT
        except Exception as e:
            pass
        return JsonResponse(ret)

• 我们可以添加一个message

class MyPermission(object):
    message = "无权访问"
    def has_permission(self, request, view):
        if request.user.user_type != 3:
            return False
        return True

源码流程

梳理：

1. 使用
   • 类，必须继承：BasePermission，必须实现：has_permission方法

from rest_framework.permissions import BasePermission

class SVIPPermission(BasePermission):
    message = "必须是SVIP才能访问"
    dehas_permission(self,request,view):
        if request.useuser_type != 3:
            return False
        return True

• 返回值：
  • True, 有权访问
  • False，无权访问
• 局部

class UserInfoView(APIView):
    """
    订单相关业务（普通用户、VIP）
    """
    permission_classes = [MyPermission1, ]

    def get(self,request,*args,**kwargs):
        return HttpResponse('用户信息')

• 全局

REST_FRAMEWORK = {
"DEFAULT_PERMISSION_CLASSES":['api.utils.permission.SVIPPermission']
}
