问题
Using perseo cep, I set a rule to it. I get this message in the Perseo fron End's Log: http://perseo-core:8080/perseo-core/rules returns {"code":200,"body":{}}. Then when I modify an attribute, in the Perseo Core's Log I see this message: msg=Firing Rule: MapEventBean. So far, so good, but then again in the Perseo FE's log I get the message: msg=missing subservice header msg=missing service header, and it is not updating my entity.
This is the log: time=2019-05-11T14:30:48.774Z | lvl=INFO | corr=n/a | trans=n/a | op=checkRequest | comp=perseo-fe | srv=n/a | subsrv=n/a | msg=missing subservice header time=2019-05-11T14:30:48.774Z | lvl=INFO | corr=n/a | trans=n/a | op=checkRequest | comp=perseo-fe | srv=n/a | subsrv=n/a | msg=missing service header time=2019-05-11T14:30:48.774Z | lvl=INFO | corr=5229c32c-362a-43f6-acda-11d6d8198261; perseocep=21 | trans=5229c32c-362a-43f6-acda-11d6d8198261 | op=/version | path=/version | comp=perseo-fe | srv=unknownt | subsrv=/ | from=::1 | msg=incoming request {"method":"GET","url":"/version","headers":{"host":"localhost:9090","user-agent":"curl/7.52.1","accept":"/"},"body":{},"subservice":"/","service":"unknownt"} time=2019-05-11T14:30:48.774Z | lvl=INFO | corr=5229c32c-362a-43f6-acda-11d6d8198261; perseocep=21 | trans=5229c32c-362a-43f6-acda-11d6d8198261 | op=/version | path=/version | comp=perseo-fe | srv=unknownt | subsrv=/ | from=::1 | msg=sending
Mi Rule:
{ "name": "pruebaUpdate", "text": "select ev.temperature? as temperature, ev.id? as id, \"pruebaUpdate\" as ruleName from pattern [every ev=iotEvent(cast(cast(temperature?,String),float) > 45 and type=\"AirQualityObserved\")]", "action": [{ "type": "update", "parameters": { "id":"${id}", "type":"AirQualityObserved", "version": "2", "attributes":[ { "name": "abnormal", "type": "boolean", "value": "true" } ] } }] }
I want to update one attribute when other attribute is higher than a value, that attribute is in some entities but not in other of the same type. I am not getting to update that attribute.
回答1:
msg=missing subservice header, msg=missing service header typically mean that the incoming request doesn't have the fiware-service and fiware-servicepath HTTP headers in which multitenancy is based. The FIWARE multitenancy model is described here.
回答2:
Placing the rule in the correct place I didn't get the error of "missing service subservice". I registered the rule with http://perseo-fe-ip:9090/rules and I fixed the problems.
