通过REST API调用将设备添加到OPC-UA IoT Agent

Question

我正在努力尝试通过API调用添加设备。如果我用docker-compse.yml启动docker容器，我可以通过以下REST API调用将设备加载到本地OPC-UA服务器。

curl http://localhost:4001/iot/devices -H "fiware-service: opcua_car" -H "fiware-servicepath: /demo" -H "Content-Type: application/json" -d @testCommands/add_device_NGSIv2.json

但是，如果我用docker-compse-external-server.yml启动docker容器，而不是iotagent4fiware/iotagent-opcua:latest使用iotagent4fiware/iotagent-opcua:1.3.4，并且我使用相同的API调用，我得到以下错误:

{"name":"WRONG_SYNTAX","message":"Wrong syntax in request: Errors found validating request."}

从Docker日志:

"op":"IoTAgentNGSI.RestUtils","time":"2022-05-12T19:47:59.467Z","lvl":"DEBUG","msg":"Errors found validating request: {
"valid":false,"errors": [
{"attribute":"pattern","property":"devices.0.commands.1.object_id","expected":"^([^<>();'="]+)+$","actual":"ns=3;s=Accelerate","message":"invalid input"},
{"attribute":"pattern","property":"devices.0.commands.0.object_id","expected":"^([^<>();'="]+)+$","actual":"ns=3;s=Stop","message":"invalid input"},
{"attribute":"pattern","property":"devices.0.attributes.4.object_id","expected":"^([^<>();'="]+)+$","actual":"ns=3;s=Oxigen","message":"invalid input"},
{"attribute":"pattern","property":"devices.0.attributes.3.object_id","expected":"^([^<>();'="]+)+$","actual":"ns=3;s=Temperature","message":"invalid input"},
{"attribute":"pattern","property":"devices.0.attributes.2.object_id","expected":"^([^<>();'="]+)+$","actual":"ns=3;s=EngineStopped","message":"invalid input"},
{"attribute":"pattern","property":"devices.0.attributes.1.object_id","expected":"^([^<>();'="]+)+$","actual":"ns=3;s=Acceleration","message":"invalid input"},
{"attribute":"pattern","property":"devices.0.attributes.0.object_id","expected":"^([^<>();'="]+)+$","actual":"ns=3;s=EngineBrake","message":"invalid input"},
{"attribute":"pattern","property":"devices.0.lazy.0.object_id","expected":"^([^<>();'="]+)+$","actual":"ns=3;s=Speed","message":"invalid input"}
]
}

然后，如果我在Node.js中运行代理，我得到相同的错误:

{"name":"WRONG_SYNTAX","message":"Wrong syntax in request: Errors found validating request."}

如果我尝试使用iotagent4fiware/iotagent-opcua:latest，这应该与在Node.js中运行克隆存储库相同，它似乎忽略了configuration.properties文件中存在的endpointUrl，并且它尝试始终连接到opc.tcp://iotcarsrv:5001/UA/CarServer。当然，连接失败…

我很困惑的行为，我不能添加任何东西到IoTAgent。

请尝试使用此curl添加新设备

curl --location --request POST 'http://localhost:4001/iot/devices' 
--header 'fiware-service: opcua_car' 
--header 'fiware-servicepath: /demo' 
--header 'Content-Type: application/json' 
--data-raw '{

我找到了一种使其工作的方法，查看了存储库上的另一个问题。使用"*";不是"="one_answers":"我已经克服了语法问题，而不是";"

该语法存在于文件testCommandsMultiDeviceTestadd_device_lazy_attrs.json中，但没有记录。
