I have tried sending "CreateElement" by Json but the response is 500 Internal Error.

Does DataMiner support Json format of this method?

The response is as belows.

{
"Message": "型 'System.String' のオブジェクトを型 'System.Int32[]' のオブジェクトに変換できません",
"StackTrace": " 場所 System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)\r\n 場所 System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)\r\n 場所 System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams)\r\n 場所 System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)\r\n 場所 System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)\r\n 場所 System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)",
"ExceptionType": "System.InvalidOperationException"
}

The following is the request I send to DataMiner.

Hi Tomoya,

I performed a small test using the driver (connector) Microsoft Platform and I was able to create the element using the following JSON message:

  • URL: http://localhost/API/v1/json.asmx/CreateElement
  • HTTP Method: POST

Headers:

  • Content-Type: application/json
  • host: localhost

Body:

{
    "connection": "10df979a-6bbd-412b-9182-66a38f0ec4eb",
    "dmaID": 24202,
    "viewIDs":
    [
        154
    ],
    "configuration":
    {
        "name": "TEST_MICROSOFT_ELEMENT",
        "description": "Description Text",
        "protocolName": "Microsoft Platform",
        "protocolVersion": "Production",
        "type": "Information Platform",
        "ipAddress": "127.0.0.1",
        "ports":
        [
            {
            "__type": "Skyline.DataMiner.Web.Common.v1.DMAElementSerialPortInfo",
            "ipAddress": "127.0.0.1",
            "type": "tcp",
            "retries": 0,
            "timeoutTime": 1500,
            "elementTimeoutTime": 30000
            }
        ]     }
}

I modified the following attributes according to your example:

  • connection: "10df979a-6bbd-412b-9182-66a38f0ec4eb"
  • dmaID: 24202
  • ViewID: 154

Please could you test creating an element and let us know if it works for you?

DMA version used for tests: 10.1.3.0-9963
