parsing调用后JavaScript JavaScriptJS

我正在与fiware合作，当进行订阅时，这些信息被发送到我的rest API中定义的一个方法，并且我想将这些信息保存在我的数据库中。

从ContextBroker获得的信息是：

{   "subscriptionId": "5a268a598dc68904bbc7b3cf",   "originator": "localhost",   "contextResponses": [     {       "contextElement": {         "type": "Temperature",         "isPattern": "false",         "id": "S_Temp001",         "attributes": [           {             "name": "Tem_int",             "type": "float",             "value": 22,             "metadatas": [               {                 "name": "accuracy",                 "type": "Float",                 "value": 44}             ]           },           {             "name": "Tem_out",             "type": "Integer",             "value": 22           }         ]       },       "statusCode": {         "code": "200",         "reasonPhrase": "OK"       }     }   ] } 

我在我的API中定义的方法是这样的：

 // insertBD    function postinsertbdarduino1 (req, res) {      var inver = {        fiwareServicePath: String,        entityId: String,        entityType: String,        attrName: String,        attrType: String,        attrValue: String,        attrMd: String      };      var params = req.body;      // check if the pass && name etc arrive and encrypt        // Assign values ​​to the user object        //inver.entityId = params.entityId;        inver.fiwareServicePath = params.fiwareServicePath;        inver.entityId = params.id;        inver.entityType = params.type;        inver.attrName = params.name;            inver.attrType = params.attrType;            inver.attrValue = params.attrValue;            inver.attrMd = params.attrMd;        pool.getConnection (function (err, connection) {        if (err) {          console.log ('Error requesting a connection:' + err);          return;        }        console.log ("connection tests");        // if we want to add other conditions in the where would it be to put the fields and? and then to what is it equivalent        // 'SELECT * FROM all WHERE id =? AND username =? ', [Req.params.id, user.username], function (err, rows)        connection.query ('INSERT INTO inver SET?', [inver], function (err, rows) {          if (err)          {            throw err;            console.log ('Error when connecting' + error);          }          else          {            res.status (200) .json (rows);          }        });        // so that it can be reused by the pool, it is important to "release" it        connection.release ();        });    } 

现在我只是通过id，types和名称。

但是他把我的logging保存在空的数据库中。

我怎样才能解决这个问题？

感谢问候。

EDIT1

我刚刚启动了JSON，我的API方法更改了subscriptionId值inver.entityId = params.subscriptionId; 如果数据到达，但我需要恢复数据" type ":" Temperature " " id ":" S_Temp001 ",

 {                "name": "Tem_int",                "type": "float",                "value": 22,                "metadatas": [                  {                    "name": "accuracy",                    "type": "Float",                    "value": 44}                ]              },    {                "name": "Tem_out",                "type": "Integer",                "value": 22              } 

我怎样才能到达JSON的那一部分？

谢谢。

好，

我修改这个问题。

我如何在NODEJS JavaScript中运行这个JSON：

  {  "subscriptionId": "5a268a598dc68904bbc7b3cf",  "originator": "localhost",  "contextResponses": [    {      "contextElement": {        "type": "Temperature",        "isPattern": "false",        "id": "S_Temp001",        "attributes": [          {            "name": "Tem_int",            "type": "float",            "value": 2,            "metadatas": [              {                "name": "accuracy",                "type": "Float",                "value": 2}            ]          },          {            "name": "Tem_out",            "type": "Integer",            "value": 1          }        ]      },      "statusCode": {        "code": "200",        "reasonPhrase": "OK"      }    }  ] } 

问候，谢谢。
