Django Rest Framework批量请求

Question

我试图在Google的batch requests精神中，在Django Rest Framework中创建一个批处理端点。为此，端点使用TokenAuthentication并在必要时请求带有路径，方法和数据的json编码的字典列表，如下所示：

[
    {
        "path": "/endpoint1",
        "method": "GET"
    },
    {
        "path": "/endpoint2",
        "method": "GET"
    },
    {
        "path": "/endpoint3",
        "method": "POST",
        "data": {
            "file": "<base64>"
        }
    }
]

视图迭代列表，复制请求（使用令牌），根据每个项目设置路径和方法，并通过解析路径获得响应。这是代码：

from copy import copy

@api_view(["POST"])
@authentication_classes((SessionAuthentication, TokenAuthentication))
@permission_classes((IsAuthenticated,))
def batch(request):
    operations = request.data
    responses = []
    for operation in operations:
        op_request = copy(request._request)
        op_request.path = operation["path"]
        op_request.method = operation["method"]
        view, args, kwargs = resolve(operation["path"])
        response = view(op_request, *args, **kwargs)
        operation["response"] = {
            "status": response.status_code,
            "data": response.data
        }
    return Response(operations)

所有非批处理端点都使用相同的autentication_classes和permission_classes。我遇到的问题是，身份验证标头与调度视图不同。也就是说，/endpoint3在发送文件（带有用户令牌）时的常规响应是成功的响应：

{
    "id": "asdf",
    "name": "asdf.txt",
}

但是当批量运行时它会像这样结束：

[
    ...<other operations>...,
    {
        "response": {
            "status": 403,
            "data": {
                "detail": "CSRF Failed: CSRF cookie not set."
            }
        },
        "path": "/endpoint3",
        "method": "POST",
        "data": {
            "file": "<Base64>"
        }
    }
]

我是否正确地将标题传递给我要发送的新请求？
