Question

我有一个JSON响应，其中填充了配置数据，我想用JSON响应中的各个元素动态填充我的配置变量，而不用写一行来分配每个变量。

检索我的JSON文件的代码：

configObj = require("./Config.js");

ws_server.getConfigHTTPRequest(function(data){

    jsonObject = JSON.parse(data.toString().replace("//","",));

        var keys = Object.keys(jsonObject);
        keys.forEach(function(key){

        //here i want to assign the values to their respective values in the 
        //config object according to the key value
        //i tried this : configObj.key = jsonObject[key], but it doesnt 
        //assign the values although JSON object keys are named the same 
        // as my config object variables

       console.log(key +': '+ jsonObject[key])

        });  

});

这是我的配置对象：

module.exports = {
    coldfusion_WS : "ws://192.168.#####/cfusion/cfusion/", 
    readerURI: "tmr://192.168.###",
    serialPort: "COM5",
    KIOSKID: "3",
    kiosktype: "IN",
    baudRate: 9600 ,
    coldFusionIP:"192.168.###",
    coldFusionPort:"81",
    JAR_path:"C:/inetpub/wwwroot/KiosksClient/javaapi/",
    applicationName:"KioskServerV2",
    HTTPPrintUrl:"http://192.168.###/IQNFLOW/kiosk_files/",
    PdfFilePath:"C:/inetpub/wwwroot/KiosksClient/print_files/",
    PingReaderSleep:"6",
    readerPingAddress: "192.168.###" ,
    printerName:"USBPRN:Star TUP900 Presenter (TUP992)",
    printerThrearSleep:"30000" ,
    RFIDThreadSleep:"20" ,
    HTTPPath:"/KiosksServer/components/WS.cfc" ,
    GOUTIP:"172.16###" ,
    GINIP:"172.16.###" ,
    paperOut:16 ,
    doorOpen:4194304 ,
    paperLow:131072 ,
    paperNotPulled:2048 ,
    readerPower:"20",
    driverImagePath:"http://localhost:81/28010948_personal_092957.png" ,
    DriverRegWS:"http://localhost:81/driverregistrar/WS/cards.cfc",
    driverRegIP:"localhost"

}

Answer 2

请注意，如果您只想将传入对象中的每个值复制到配置对象中，则可以不使用循环进行操作：

Object.assign(configObject, jsonObject)
