Django 通道,AttributeError
Django channels, AttributeError
我正在尝试学习如何使用通道 2 通过 websocket 发送消息。
我只是想在客户端连接时发送一条简单的消息,但我一直收到属性错误:
class CameraOnlineConsumer(JsonWebsocketConsumer):
def connect(self):
self.accept()
return self.send({
"type": "websocket.accept",
"send": {'a': "Hi"}
})
加注:
self.sendMessage(content.encode("utf8"), binary)
AttributeError: 'dict' object has no attribute 'encode'
WebSocket DISCONNECT /ws/camera_online/connect [127.0.0.1:36006]
更改为:
return self.send({
"type": "websocket.accept",
"send": "Hi"
})
例如returns同样的错误。
Try convert it to json like this ..
import json
class CameraOnlineConsumer(JsonWebsocketConsumer):
def connect(self):
self.accept()
return self.send(json.dumps({
"type": "websocket.accept",
"send": {'a': "Hi"}
}))
