Question

我使用Cepheus GE作为我的用例，我在多租户模式下启用它并将config.json文件上传到它，但是当我开始向Cepheus代理发送更新以便将它们转发给CEP，Cepheus经纪人只是接收更新，但没有将它们转发给Cepheus上限，因为它无法识别config.json中设置的服务和服务路径。当我尝试将更新直接发送到Cepheus-CEP时，它接受了它们并成功处理了它们。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。

发送更新的脚本文件如下

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

现在请问我想知道问题出在哪里？

截至今天，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，与像猎户座这样的全权经纪人相比，经纪人的功能很少。

如果您需要多租户代理，请使用猎户座上下文代理：https://fiware-orion.readthedocs.io/en/master/user/multitenancy/index.html

错误Cepheus经纪人没有转发Cepheus CEP的更新
