java - 如何访问DRF服务器端的请求主体模型字段？

Question

在 Android 客户端，我向服务器端点发出请求，其正文为 ContactRequest:

public class ContactRequest {

    @SerializedName("senderId")
    @Expose
    private int senderId;

    @SerializedName("receiverId")
    @Expose
    private int receiverId;

    public ContactRequest(int senderId, int receiverId) {
        this.senderId = senderId;
        this.receiverId = receiverId;
    }
}

使用改造，我将此对象作为请求正文传递:

@POST("friendship/create-friend-request/")
Call<Void> sendRequest(@Body ContactRequest contactRequest);

然后，在服务器端，我将此端点映射到 CreateFriendRequestView:

class CreateFriendRequestView(views.APIView):

    def post(self, request, *args, **kwargs):
        sender = User.objects.get(pk=request.senderId)
        receiver = User.objects.get(pk=request.receiverId)
        Friend.objects.add_friend(sender, receiver)
        return Response({'status': 'Request sent'}, status=201)

但是，当向此端点发出请求并调用 View 时，会出现内部服务器错误，状态代码 500。

AttributeError: 'Request' object has no attribute 'senderId'

如何在 django Rest Framework 客户端引用字段 senderId 和 receiverId？

Answer 1

请求数据位于请求对象的data字段中。

结帐http://www.django-rest-framework.org/api-guide/requests/#data

你必须使用:

sender = User.objects.get(pk=request.data.get('senderId'))

request.data是一个Python字典。
