[英]Python MQTT publisher doesn't publish
Trying to publish some data from a raspberry pi, but nothing gets through.试图从树莓派发布一些数据,但没有通过。 However, publishing via MQTT.fx works fine.
但是,通过 MQTT.fx 发布可以正常工作。 This is my python script:
这是我的 python 脚本:
import paho.mqtt.client as mqtt
import paho.mqtt.publish as publish
publish.single("example_topic", payload="example message", qos=0, retain=False,\
hostname="example.com",port=8883, client_id="random_number", \
keepalive=60, will=None,auth = {'username':"example_username",\
'password':"example_password"}, tls=None, protocol=mqtt.MQTTv311, transport="tcp")
This might be important to know: In MQTT.fx I wasn't able to connect without navigating to "SSL/TLS", making a cross next to "Enable SSL/TLS" and then making a cross next to "CA signed server certificate".这可能很重要:在 MQTT.fx 中,我无法连接,除非导航到“SSL/TLS”,在“启用 SSL/TLS”旁边打叉,然后在“CA 签名服务器证书”旁边打叉”。
Can someone tell me what I'm doing wrong?有人可以告诉我我做错了什么吗? :)

You seem to be mixing different things up here.你似乎在这里混合了不同的东西。 The
publish.single
doesn't need any of the mqtt.Client()
stuff. publish.single
不需要任何mqtt.Client()
东西。 It is designed to to EVERYTHING in a single function call.它设计用于在单个 function 调用中处理所有内容。
publish.single()
takes options for everything. publish.single()
接受所有选项。 The docs are here文档在这里
import paho.mqtt.publish as publish
publish.single(topic, payload=None, qos=0, retain=False, hostname="localhost",
port=1883, client_id="", keepalive=60, will=None,
auth={username:"user", password:"pass"}, tls=None,
protocol=mqtt.MQTTv311, transport="tcp")
