我已经在固件映像 CentOS-7-x64 上安装了 cygnus 0.8.2,我使用以下方式订阅了 orion 上下文代理:
(curl 193.48.247.246:1026/v1/subscribeContext -s -S --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Fiware-Service: egmmqtt' --header 'Fiware-ServicePath: /egmmqttpath' -d @- | python -mjson.tool) <<EOF
{
"entities": [
{
"type": "sensors",
"isPattern": "false",
"id": "sensors:switch2A"
}
],
"attributes": [
"switch2A"
],
"reference": "http://193.48.247.223:5050/notify",
"duration": "P1M",
"notifyConditions": [
{
"type": "ONCHANGE",
"condValues": [
"switch2A"
]
}
],
"throttling": "PT1S"
}
EOF
没有通知到达 cygnus,我在 orionContextBroker 日志中收到此错误:
time=2015-10-06T17:43:37.898CEST | lvl=WARNING | trans=1443447780-161-00000000423 | function=sendHttpSocket | comp=Orion | msg=clientSocketHttp.cpp[358]: Notification failure for 193.48.247.223:5050 (curl_easy_perform failed: Couldn't connect to server)
我不知道为什么在关联的公共 IP 地址下无法访问 cygnus 实例。事实上,我无法从 Orion 实例 ping cygnus 机器实例。关于我错过了什么的任何想法?谢谢!
