我猜我的组织的代理设置阻止了请求，因此请引导我在上面的代码中包含代理设置。
例如，如果地址是＆＃39; proxy.xyz.com＆＃39;和端口号是＆＃39; 0000＆＃39;我的网络用户名是＆＃39; xyz＆＃39;和密码是＆＃39; abc＆＃39;

Answer 1

您还没有提到您正在谈论的代理类型，但假设您要使用HTTP代理。

由于两个协议不兼容，您无法使用HTTP代理转发原始MQTT流量。

如果您要连接的代理通过Websockets支持MQTT，那么您应该能够连接现代HTTP代理，但这不适用于您发布的代码。

Answer 2

您的代码应遵循以下规定

import socks
import socket
import paho.mqtt.client as mqtt

client = mqtt.Client(client_id='the-client-id')
client.username_pw_set('username', 'password')
# set proxy ONLY after client build but after connect
socks.setdefaultproxy(proxy_type=socks.PROXY_TYPE_HTTP, addr="proxy.xyz.com", port=0000, rdns=True,username="xyz", password="abc")
socket.socket = socks.socksocket
# connect
client.connect('mqtt.host', port=1883, keepalive=60, bind_address="")
client.loop_forever()

Answer 3

我在使用socks代理服务器和PySocks的情况下解决了此问题

import socks
import socket
import paho.mqtt.client as mqtt

client = mqtt.Client(client_id='the-client-id')
client.username_pw_set('username', 'password')
# set proxy ONLY after client build but after connect
socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS4, "socks.proxy.host", 1080)
socket.socket = socks.socksocket
# connect
client.connect('mqtt.host', port=1883, keepalive=60, bind_address="")
client.loop_forever()

Answer 4

Paho社区在2018年添加了此功能。 https://github.com/eclipse/paho.mqtt.python/pull/315

由于没有人添加代码段，因此我正在添加代码段。只需为客户端对象设置代理选项。

client = mqtt.Client()    
client.proxy_set(proxy_type=socks.HTTP, proxy_addr=proxy_host, proxy_port=proxy_port)

如何在Paho-MQTT中添加代理设置？
