这是我的asgi.py文件：

import os
import django
from channels.routing import get_default_application
from channels.layers import get_channel_layer

os.environ.setdefault('DJANGO_SETTINGS_MODULE','ProfilesApp.settings.development')
django.setup()
application = get_default_application()
channel_layer = get_channel_layer()

settings.py

Asgi_APPLICATION = "ProfilesApp.routing.application"
Wsgi_APPLICATION = 'ProfilesApp.wsgi.application'
CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "channels_redis.core.RedisChannelLayer","CONfig": {
            "hosts": [os.environ.get('REdis_URL','redis://localhost:6379')],},}

请先让我知道如何解决此问题

解决方法

您使用了错误的asgi配置，该配置用于1.x频道

documentation的状态应为

extension Image {
    func centerCropped() -> some View {
        Color.clear
        .overlay(
            self
            .resizable()
            .scaledToFill()
        )
        .clipped()
    }
}

,

asgi.py应该是这样的：

import os
import django
from channels.routing import get_default_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE","myproject.settings")
django.setup()
application = get_default_application()

和ProcFile应该是这样的

web: daphne myproject.asgi:application --port $PORT --bind 0.0.0.0 -v2
chatworker: python manage.py runworker --settings=myproject.settings.production -v2
