1 启动Redis服务

从 Redis for Windows https://github.com/tporadowski/redis/releases

安装后启动redis-server.exe

2 验证

python manage.py shell

import channels.layers
channel_layer = channels.layers.get_channel_layer()
from asgiref.sync import async_to_sync
async_to_sync(channel_layer.send)('test_channel', {'type': 'hello'})
async_to_sync(channel_layer.receive)('test_channel')

期望输出：

{'type': 'hello'}

3 运行项目

python manage.py runserver

进入 http://127.0.0.1:8000/chat/ 输入聊天室名称进入聊天

4. 运行测试
