我在python控制台中尝试了Group(groupname).send
它似乎不起作用。这是为什么?
这是我的consumer.py安排:
def ws_connect(message):
message.reply_channel.send({"accept": True})
Group(secure_group).add(message.reply_channel)
def ws_receive(message):
# Nothing to do here
Group(secure_group).send({
"text": "Received {}".format(message.content['text'])
})
def ws_disconnect(message):
Group(secure_group).discard(message.reply_channel)
路由:
from channels.routing import route
from App.consumers import (
ws_connect,
ws_receive,
ws_disconnect
)
channel_routing = [
route("websocket.connect", ws_connect),
route("websocket.receive", ws_receive),
route("websocket.disconnect", ws_disconnect),
]
终端命令:
from channels import Group
#import secure_group here
Group(secure_group).send({ "text": "Tester" })
我的所有客户都没有收到过该文本。
CHANNEL_LAYERS
config:
CHANNEL_LAYERS = {
"default": {
"BACKEND": "asgiref.inmemory.ChannelLayer",
"ROUTING": "App.routing.channel_routing",
},
}

Inmemory
频道图层不支持cross-process communication
。您无法在其他终端中执行群组发送。尝试使用Redis后端,您可以发送消息。
