錯誤仙王星經紀不轉發更新到仙王座CEP

Question

我使用Cepheus GE爲我的用例，我啓用它在多租戶模式，並上傳我的config.json文件，但當我開始發送更新到仙王座經紀人的順序爲了將它們轉發給CEP，Cepheus經紀人只收到更新，但不會將它們轉發給Cepheus上限，因爲它無法識別在config.json中設置的服務和服務路徑。當我試圖將我的更新直接發送到Cepheus-CEP時，它接受併成功處理了它們。所以我想知道爲什麼Cepheus經紀人在多租戶模式下啓用時無法識別Fiware服務。

配置文件服務定義如下

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

這是仙王座經紀人的日誌。

併發送更新的腳本文件如下所示

    {

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

現在請我想知道這個問題可能是什麼？

Answer 1

到目前爲止，Fiware-Cepheus代理不支持多租戶請求（使用Fiware-Service和Fiware-ServicePath標頭），只有CEP可以處理多租戶。更一般地說，與像Orion這樣的全面經紀人相比，經紀人的功能非常少。

如果你需要一個多租戶代理，請使用獵戶座上下文經紀人：https://fiware-orion.readthedocs.io/en/master/user/multitenancy/index.html
