Question

我想让一个MQTT代理与OAUTH2服务器进行身份验证。

我正在使用Paho在Python 3中编码MQTT客户端。

我已成功连接到IS以获取访问令牌。

我已经通过MQTT Message Broker成功发送了json消息。

我已经按照正式说明将WSO2 Message Broker和Identity Server配置为可以一起工作。

当我尝试连接身份验证信息时，无法正确发送要处理的acces令牌。

client = mqtt.Client("oauthmqttcli") 
client.connect(broker_address, port=1883) #connect to broker
client.username_pw_set(access_token)
client.publish("test","{'a':'b'}")

在日志中，我看到了：

如何将访问令牌发送到要访问的服务器？ Message Broker在哪里搜索访问令牌？

Answer 1

我终于找到了。访问令牌必须作为用户名发送，密码为空。

client = mqtt.Client("dev7") 
client.username_pw_set(username=access_token,password="")
client.connect(broker_address, port=broker_port) #connect to broker
print("Connected")
client.publish("test","{'c':'Payload!'}")
print("Sending message")
