一、websocket介绍:
channels 4.0之后默认不带Daphne服务器了。
解决方案可以有两种:
1.指定channels的版本为3.x;
2.安装时使用pip3 install -U channels[“daphne”]
二、后端
1. 安装(基于django3.x)
pip3 install channels==3.0.3 -i https://pypi.douban.com/simple
2. settings配置
a. app注册
INSTALLED_APPS = [
'channels',
]
b. 配置变量
ASGI_APPLICATION = "qq_chart.asgi.application"
ASGI_APPLICATION = '当前项目名同名的文件名.asgi.application'
3.修改asgi文件(默认不支持websocket,只支持http)
import os
from django.core.asgi import get_asgi_application
from channels.routing import ProtocolTypeRouter, URLRouter
from . import routings
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'qq_chart.settings')
# application = get_asgi_application()
application = ProtocolTypeRouter({
'http':get_asgi_application(),
'websocket':URLRouter(routings.websocket_urlpatterns)
})
