对于我的 API GET 操作，我使用节点获取，我的代码是

var fetch = require('node-fetch');

const HttpProxyAgent = require('http-proxy-agent');
const HttpsProxyAgent = require('https-proxy-agent');

fetch('https://threemashery.rb.ipdesign.info/cit1/apigw/tibs/nbrmgmt/NumberManagementService/v1/RetrieveListDNForSelection?apikey=5w8anhcabembfp7tne67rhk8&userID=cpacadm&quantity=2&operatorId=3UK&orderNumber=ORD12341&numberCategory=Normal', {method: 'GET', agent: new 
HttpsProxyAgent('http://10.10.104.4:50683') })
.then(resRaw=>{

    return resRaw.text();


})
.then(resJson=>{

    console.log(resJson);

    console.log(resJson.Header);

})

下面是我的两个控制台日志输出

{"Header":{"ActivityName_T":"AS_DNLogicalResource_NM","MsgType_T":"RESPONSE","msgName":"Error occured while processing request for List DN","Source":"RetrieveListDNLogicalResourceNM","ActivityStatusEnum_T":"FAILURE","ActivityStatus_T":"rcFailure","Timestamp":"2018-07-26T14:45:14.009Z","ProviderInfo":[{"name":"b08359a6-dea1-4e34-9c47-8d5971e1a9dd1532616302405","valueType":"rcFailure","description":"Order is being modified.","Value":{"CharacteristicValue":[{"value":"FAILURE"}]}}]},"Payload":{"NotificationDetails":[{"errorCode":"rcFailure","errorDescription":"Order is being modified."}]}}

undefined

为什么我在尝试获取第一个元素时变得未定义？有人请帮助我。

即使我尝试了以下

console.log(resJson);
    let res=JSON.stringify(resJson);
    console.log(res);

但我越来越喜欢

{"Header":{"ActivityName_T":"AS_DNLogicalResource_NM","MsgType_T":"RESPONSE","msgName":"Error occured while processing request for List DN","Source":"RetrieveListDNLogicalResourceNM","ActivityStatusEnum_T":"FAILURE","ActivityStatus_T":"rcFailure","Timestamp":"2018-07-26T14:40:40.189Z","ProviderInfo":[{"name":"4463c84f-4d38-4173-8f11-3b82b2c539a51532616029573","valueType":"rcFailure","description":"Order is being modified.","Value":{"CharacteristicValue":[{"value":"FAILURE"}]}}]},"Payload":{"NotificationDetails":[{"errorCode":"rcFailure","errorDescription":"Order is being modified."}]}}

为什么我在尝试获取第一个元素时变得未定义？

你说return resRaw.text()的resJson是回复的文字。

简单的字符串没有Header属性。

如果return resRaw.json()要将响应解析为 JSON 并将生成的对象放入resJson.

即使我尝试了以下

let res=JSON.stringify(resJson);

那是在错误的方向上。您正在获取字符串，然后用JSON 表示它。

您需要将 JSON 解析为 JavaScript 数据。
