Orion CB不处理物联网代理回复-Java 学习之路

我正在开发一个系统，我使用Orion CB作为主要事件总线，也使用iotagent节点lib，以便与第三方API Build 接口 .

现在发生的是我在iotagent上注册一个只有惰性属性的新设备，其中一个应该是一个json字符串 .

覆盖查询处理程序及其子函数我尝试将这个json字符串字符串化并将其保留为json格式，这就是我得到的：

1）字符串化json：
当我查询Orion来检索实体时，它会回复该实体不存在，状态代码为404.查看iotagent调试日志，我看到它的响应正是我所期望的（所有属性格式正确），并以"statusCode"结束：{"code"：200，"reasonPhrase"："OK"}所以似乎iotagent正在回复Orion，状态代码为200（成功！） .

2）保持json原样：
当我查询Orion以检索它回复状态代码为200的实体时，所有属性都可以，但是带有json的属性是空的 . 再次，看看iotagent调试日志，我看到响应是我想要查询到Orion的响应，它以"statusCode"结尾：{"code"：200，"reasonPhrase"："OK"} .

这里发生了什么？第一种情况可能是什么问题？似乎由于某种原因，Orion不喜欢iotagent的反应，它说实体不存在 . 而在第二种情况下，我认为问题可能出在不允许的数据结构中（json作为属性值） .

我错过了什么吗？如果有人可以帮助我解决这个问题，我会很高兴，如果您需要更多信息，请告诉我 .

编辑：

这就是我配置设备的方式：

{
    "devices": [
        {
            "device_id": "taxi_list",
            "entity_name": "taxi_list",
            "entity_type": "taxilist",
            "lazy": [
                {
                    "name": "taxiPosition",
                    "type": "StructuredValue"
                },
                {
                    "name": "error",
                    "type": "string"
                },
                {
                    "name": "status",
                    "type": "string"
                },
                {
                    "name": "corsaRuntime",
                    "type": "string"
                }
            ]
        }
    ]
}

我需要拥有json的属性是“taxiPosition”，因此它的类型是“StructuredValue” . 创建响应我只是在'device'检索的有效负载上使用JSON.parse（），并将此值分配给属性，如：

responses.push({
                name: 'taxiPositions',
                type: 'StructuredValue',
                value: [{...}, {...}]
        });

其中值是具有简单的一级键值对的对象数组，其格式如下：

{ "idTaxi": "100", "idStato": "1", "lat": "90.843227100000000", "lng": "64.228254600000000", "nome": "Name", "cognome": "Surname", "licenza": "24XX", "cellulare": "+39320662332XX", "email": "xxxxxx@xxxx.eu", "targa": "XX000XX", "modelloAuto": "Focus SW", "marcaAuto": "Ford", "annoImmatricolazione": "2020", "passeggeri": "4", "dataCreazione": "2014-05-05", "rank": "4.2", "n_corse": "6", "os": "A", "dataOraInizioTurno": "05-01-2018 07:51", "dataOraFineTurno": "05-01-2018 11:50", "radio": "1", "pos": "0", "nome_radio": null, "iban": "" }

当我尝试将值作为字符串传递时，代码是相同的，但属性的类型是“string”，并且通过在先前解析的json上使用JSON.stringify（）来获取值 .

要从Orion查询实体，我只需调用/ v2 / entities / taxi_list

我测试了一些格式，最后两个是最好的选择：这是一个验证json：

POST / v2 /实体

{
            "device_id": "taxi_list",
            "entity_name": "taxi_list",
            "entity_type": "taxilist",
            "lazy": [
                {
                    "name": "taxiPosition",
                    "type": "StructuredValue"
                },
                {
                    "name": "error",
                    "type": "string"
                },
                {
                    "name": "status",
                    "type": "string"
                },
                {
                    "name": "corsaRuntime",
                    "type": "string"
                }
            ]
}

答案：

POST / v2 /实体

                    "type": "string"
                }
            ]
}

答案：

POST / v2 /实体

{
            "id": "taxi_list",
            "name": "taxi_list",
            "type": "taxilist",
            "taxiPosition":{

                }
}

答案：

{
    "error": "BadRequest",
    "description": "attribute must be a JSON object, unless keyValues option is used"
}

最佳示例POST v2 / entities？options = keyValues

{
                "id": "taxi_list",
                "name": "taxi_list",

    "name": {
        "type": "Text",
        "value": "taxi_list",
        "metadata": {}
    }
}

然后，您可以使用：

？options = keyValues

此示例中的实体“id”：“taxi_list”，更有趣 . 因为Orion创建结构化格式，Orion将验证 . 在tax_list3的有效负载中，值中的字符串将表示值，而不进行Orion验证 .

阿拉戈纳]（https://stackoverflow.com/users/8362361/f-aragona）

您使用的Fiware Orion版本是什么？对于IotAgent，您使用的是最新的吗？

另一方面，强烈建议使用docker-compose来部署你正在使用的所有服务，除非是Mosquitto

version : "2"

services:
  mongo:
    image: mongo:3.2
    command: --nojournal
    ports:
      - "27017:27017"
    expose:
      - "27017"
  orion:
    image: fiware/orion
    links:
      - mongo
    ports:
      - "1026:1026"
    command: -dbhost mongo
    expose:
      - "1026"

对于Mosquitto和IotAgent，您必须从源代码安装它 .

git clone https://github.com/telefonicaid/iotagent-json.git

克隆并安装后，必须根据IP容器设置 config.js . 附上我给你一些脚本，以创建一个实体和一个设备 . 为了将 device 分配给 entity ，一步一步地遵循是很重要的

Scripts

1.Create Service

#!/bin/bash

    curl -X POST -H "Fiware-Service: myHome" -H "Fiware-ServicePath: /environment" -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{
"services": [
    {
          "resource": "/",
          "apikey": "1234",
          "type": "multiSensor",
          "cbroker":"172.18.0.3:1026"
    }
    ]
}' 'http://localhost:4041/iot/services'

注意：

必须在 config.js IotAgent JSON文件中定义 "apikey": "1234" 字段 .
"cbroker":"172.18.0.3" 字段是ORION IP容器

2 Create Device

#!/bin/bash

    curl -X POST -H "Fiware-Service: myHome" -H "Fiware-ServicePath: /environment" -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{ 
    "devices": [ 
        { 
            "device_id": "sensor00", 
            "entity_name": "R2-D2", 
            "entity_type": "robot",
            "attributes": [
              {
                "name": "temperature",
                "type": "celsius"
              },
              {
                "name": "Position",
                "type": "string"
              }
            ]
        }
    ]
}

' 'http://localhost:4041/iot/devices'

3.Send meassures to OCB （使用IotAgent-JSON导致有效负载）

mosquitto_pub -t /1234/sensor00/attrs -m '{"temperature": 40.2,"Position": "left"}'

4.Query to Orion to see results

curl -X POST -H "Content-Type: application/json" -H "Accept: application/json" -H "Fiware-Service: myHome" -H "Fiware-ServicePath: /environment" -d '{
    "entities": [
        {
            "isPattern": "false",
            "id": "R2-D2",
            "type": "robot"
        }
    ]
}' 'http://172.18.0.3:1026/NGSI10/queryContext'

如果你解决了，请告诉我 .
