错误 Cepheus 代理未将更新转发到 Cepheus CEP

Question

我将 Cepheus GE 用于我的用例，并在多租户模式下启用它并将我的 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到 CEP 时， Cepheus 代理仅接收更新，但不会将它们转发到 Cepheus 上限，因为它无法识别在 config.json 中设置的服务和服务路径。当我尝试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 代理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": "string",
            "value": "Controller111"
        }
        ]
    }
],
    "updateAction": "UPDATE"
}
EOF

现在我想知道问题可能出在哪里？

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 Orion 这样的成熟代理相比，代理的功能非常少。

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