Question

我的IoT项目遇到一些问题后，请参见以下主题： Mosquitto Broker Bridge Configuration - unacceptable protocol version实现网桥连接还有一个问题。

我在安装了Raspbian Stretch的Raspberry Pi上使用Mosquitto v1.6.7。 mosquitto代理桥与远程代理（SAP IoT Cloud）之间的连接无法建立。我再次仔细检查了所有设置（端点地址正确，CAcert.pem是我从客户端发送到没有桥的远程代理时使用的相同名称，再次感谢所有提示！

这是我为蚊子经纪人更新的配置：

我已经取消了连接名称和地址的个性化设置。连接名称在远程代理（SAP Cloud）中用作clientId，并且经过仔细检查和端点地址。

listener 8883

connection raspberryPiZero
address xxxxxxxx.eu10.cp.iot.sap:8883
bridge_protocol_version mqttv311
try_private false
topic # both
log_type all
bridge_cafile /etc/mosquitto/certs/CAcert.pem

这是更新的日志文件：

远程客户端ID

设置此网桥连接的客户端ID。如果未定义，则此   默认为'name.hostname'，其中name是连接名称，   hostname是这台计算机的主机名。

这将替换旧的“ clientid”选项，以避免与   桥梁的本地/远端。 “ clientid”对于   暂时。

这意味着提供给远程代理的clientid是raspberryPiZero.raspberrypi而不是raspberryPiZero。如果客户端ID仅需raspberryPiZero，则需要使用remote_clientid选项进行设置。

那将使客户端ID正确。接下来，您需要告诉本地代理使用您的客户端使用的所有相同证书。

您将需要使用bridge_certfile指向客户端证书文件，并使用bridge_keyfile指向未加密的客户端私钥。

connection raspberryPiZero
address xxxxxxxx.eu10.cp.iot.sap:8883
bridge_protocol_version mqttv311
remote_clientid raspberryPiZero
try_private false
bridge_cafile /etc/mosquitto/certs/CAcert.pem
bridge_certfile /etc/mosquitto/certs/clientCert.pem
bridge_keyfile /etc/mosquitto/certs/clientKey.pem
