我試圖使用高速公路python連接到蚊子經紀人。 如果我使用sub.py裏面有這個代碼:autobahn mosquitto服務器聊天
import mosquitto
def on_connect(mosq, obj, rc):
print("rc: "+str(rc))
def on_message(mosq, obj, msg):
print(msg.topic+" "+str(msg.qos)+" "+str(msg.payload))
def on_publish(mosq, obj, mid):
print("mid: "+str(mid))
def on_subscribe(mosq, obj, mid, granted_qos):
print("Subscribed: "+str(mid)+" "+str(granted_qos))
def on_log(mosq, obj, level, string):
print(string)
mqttc = mosquitto.Mosquitto()
mqttc.on_message = on_message
mqttc.on_connect = on_connect
mqttc.on_publish = on_publish
mqttc.on_subscribe = on_subscribe
# Uncomment to enable debug messages
mqttc.on_log = on_log
mqttc.connect("localhost", 1883, 60)
mqttc.subscribe("control", 0)
rc = 0
while rc == 0:
rc = mqttc.loop()
print("rc: "+str(rc))
它連接到代理和檢索一個客戶端發佈到控制通道的所有消息。
我倒是想以某種方式使用WebSockets的這些消息推到網頁中,我想使用的WebSocket高速公路PY,從這裏修改的例子http://autobahn.ws/python/getstarted#yourfirstserver
我的代碼是這樣的
import sys
import mosquitto
from twisted.internet import reactor
from twisted.python import log
from autobahn.websocket import WebSocketServerFactory, \
WebSocketServerProtocol, \
listenWS
class EchoServerProtocol(WebSocketServerProtocol):
def on_connect(mosq, obj, rc):
print("rc: "+str(rc))
def on_message(mosq, obj, msg):
print(msg.topic+" "+str(msg.qos)+" "+str(msg.payload))
def onMessage(self, msg, binary):
print "sending echo:", msg
self.sendMessage(msg, binary)
def on_publish(mosq, obj, mid):
print("mid: "+str(mid))
def on_subscribe(mosq, obj, mid, granted_qos):
print("Subscribed: "+str(mid)+" "+str(granted_qos))
mqttc = mosquitto.Mosquitto()
mqttc.on_message = on_message
mqttc.on_connect = on_connect
mqttc.on_publish = on_publish
mqttc.on_subscribe = on_subscribe
# Uncomment to enable debug messages
mqttc.on_log = on_log
mqttc.connect("192.168.2.109", 1883, 60)
mqttc.subscribe("control", 0)
rc = 0
while rc == 0:
rc = mqttc.loop()
print("rc: "+str(rc))
if __name__ == '__main__':
log.startLogging(sys.stdout)
factory = WebSocketServerFactory("ws://192.168.2.109:8899", debug = TRUE)
factory.protocol = EchoServerProtocol
listenWS(factory)
reactor.run()
但我收到此錯誤,當我嘗試運行它:
[email protected]:~/authobahn# python myserver.py Traceback (most recent call last): File "myserver.py", line 30, in mqttc.on_message = on_message NameError: name 'on_message' is not defined
Thsnk您重播。這是否是問題所在。 – bogdanioanliviu
