如何将“url-route”键/值添加到测试的“scope”中?

我想测试一下我的消费者 scope['url_route'] HttpCommunicator 或 ApplicationCommunicator ,该参数未设置。如何设置此参数?测试文档非常有限,没有任何关于此的文档 https://channels.readthedocs.io/en/latest/topics/testing.html .

测试.py

from channels.testing import HttpCommunicator
import pytest

from my_app import consumers

@pytest.mark.asyncio
async def test_consumers():
    communicator = HttpCommunicator(consumers.MyConsumer, 'GET', '/project/1')
    response = await communicator.get_response()
    assert response['status'] == 400

我的应用程序.py

import json

from channels.db import database_sync_to_async
from channels.generic.http import AsyncHttpConsumer

from projects import model

class MyConsumer(AsyncHttpConsumer):
    async def handle(self, body):
        _id = int(self.scope['url_route']['kwargs'].get('project_id', 1))
        record = await database_sync_to_async(models.Project.objects.get)(id=_id)
        data = json.dumps({"id": _id})
        await self.send_response(200, data.encode('utf8'))
