我已经配置了Orion和Proton FIWARE Generic Enablers并在Orion中进行了订阅,以便在修改Node类型的实体时向Proton发送通知 .
碰巧Proton返回与解析收到的XML有关的错误 .
proton | Mar 02, 2016 11:46:47 AM com.ibm.hrl.proton.webapp.providers.EventXmlNgsiMessageReader readFrom
proton | INFO: started event message body reader
proton | Mar 02, 2016 11:46:47 AM com.ibm.hrl.proton.webapp.providers.EventXmlNgsiMessageReader readFrom
proton | INFO: Event: NodeContextUpdate
proton | Mar 02, 2016 11:46:47 AM com.ibm.hrl.proton.webapp.providers.EventXmlNgsiMessageReader readFrom
proton | SEVERE: Could not parse XML NGSI event java.lang.NullPointerException, reason: null
proton | last attribute name: null last value: null
我发现至少另一个用户发布了类似的问题,但该问题的答案并不适合(并解决)我的情况 .
编辑:
这是Proton收到的POST请求:
