错误仙王星经纪不转发更新到仙王座CEP

Question

我使用Cepheus GE为我的用例，我启用它在多租户模式，并上传我的config.json文件，但当我开始发送更新到仙王座经纪人的顺序为了将它们转发给CEP，Cepheus经纪人只收到更新，但不会将它们转发给Cepheus上限，因为它无法识别在config.json中设置的服务和服务路径。当我试图将我的更新直接发送到Cepheus-CEP时，它接受并成功处理了它们。所以我想知道为什么Cepheus经纪人在多租户模式下启用时无法识别Fiware服务。

配置文件服务定义如下

"brokers":[ 
    { 
     "url":"http://XXX.XX.XX.XX:1026", 
     "serviceName": "f", 
     "servicePath": "/f", 
     "authToken": "XXX" 
    } 
] 

这是仙王座经纪人的日志。

并发送更新的脚本文件如下所示

     "isPattern": "false", 
     "id": "Lab111", 
     "attributes": [ 
     { 
      "name": "priority", 
      "type": "double", 
      "value": "1" 
     },        
     { 
      "name": "controller", 
      "type": "string", 
      "value": "Controller111" 
     } 
     ] 
    } 
], 
    "updateAction": "UPDATE" 
} 
EOF 

现在请我想知道这个问题可能是什么？

到目前为止，Fiware-Cepheus代理不支持多租户请求（使用Fiware-Service和Fiware-ServicePath标头），只有CEP可以处理多租户。更一般地说，与像Orion这样的全面经纪人相比，经纪人的功能非常少。

如果你需要一个多租户代理，请使用猎户座上下文经纪人：https://fiware-orion.readthedocs.io/en/master/user/multitenancy/index.html
