mosquitto 基本操作

查看证书信息：

openssl x509 -in certificate.pem -text -noout

检查证书有效期：

// 是证书信息的一部分；只能是证书，不可是私钥

openssl x509 -in server.crt -noout -dates

证书校验:

openssl verify -CAfile ca/ca.crt server/server.crt

订阅和发布,没有 TLS

mosquitto_sub -h 192.168.111.100 -p 8883 -t "topicA" -d

mosquitto_pub -h 192.168.17.123 -p 8883 -t "topicA" -m "hello" -d

订阅和发布, +TLS

• -t:topic
• -h:host
• -p:port
• -m:message
• –cert:certificate
• –key:私钥

订阅

mosquitto_sub -h 192.168.17.123 -i 111 -p 8883 -t "111" --cafile ~/openssl/ca/ca.crt --cert ~/openssl/client/client.crt --key ~/openssl/client/client.key    

发布

mosquitto_pub -h 192.168.17.123 -p 8883 -t "111" -m "hello" --cafile ~/openssl/ca/ca.crt --cert ~/openssl/client/client.crt --key ~/openssl/client/client.key -d

调试行

printf("file:%s function:%s line:%d\n",__FILE__,__FUNCTION__,__LINE__);

websocket 调试

 curl -v -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Host: devicedrivetestIoTHub.azure-devices.net" -H "Origin: https://devicedrivetestIoTHub.azure-devices.net" -H "Sec-WebSocket-Key: SGVsbG8sIHdvcmxkIQ==" -H "Sec-WebSocket-Protocol: mqtt" -H "Sec-WebSocket-Version: 13" 'https://devicedrivetestIoTHub.azure-devices.net/$iothub/websocket'
