我正在用 python 开发一个模块,它允许我将我的树莓派连接到我的电脑上托管的 hivemq 版本。
它连接正常,但是当我添加 hivemq 的文件身份验证插件时,它似乎不起作用
我使用 username_pw_set 设置我的用户名和密码
这是我的代码目前的样子:
import paho.mqtt.client as mqtt
client = mqtt.Client()
#The callback for when the client recieves a CONNACK response from the server
def on_connect(client, userdata, flags, rc):
print("connected with the result code "+str(rc))
#Define any topics you would like the pi to
#automatically subscribe to here
#The callback for when this client publishes to the server.
def on_publish(client, userdata, mid):
print("message published")
#The callback for when a PUBLISH message is recieve from the server.
def on_message(client, userdata, msg):
print(msg.topic+" "+str(msg.payload))
def on_log(client, userdata, level, buf):
print(str(level)+" "+str(buf))
#set callbacks
def setup():
client.on_connect = on_connect
client.on_message = on_message
client.on_publish = on_publish
client.on_log = on_log
#setup connection to broker
def connect(username, password):
client.username_pw_set(username, password)
client.connect("10.19.109.152")
def publish(topic, message):
client.publish(topic, message)
def loop():
client.loop()
这可能与python客户端格式化连接请求的方式有关吗?
编辑:
服务器给我错误信息:
2015-11-26 09:50:53,723 ERROR - Could not get valid results from the webservice
org.apache.http.NoHttpResponseException: The target server failed to respond
at org.apache.http.impl.conn.DefaultHttpResponseParser.parseHead(Default
HttpResponseParser.java:143)
我的客户端(on_connect 函数)输出一条带有代码 5 的 connack 消息,该消息用于拒绝连接,因为它未经授权。
