Question

我正在尝试使用简单的NodeJS HTTP服务器从远程API获取JSON（它使用request进行HTTP调用）。当我通过一些JSON验证器运行HTTP响应时，它说它是一个有效的JSON，但是我无法管理访问密钥甚至是数组等的密钥。

JSON看起来像：

{
    "submissions": [{
        "token": "db7fa11f970f376cc17c5f8d1760ab98",
        "created_at": "2017-03-02T13:01:35Z",
        "saved_at": "2017-03-02T12:50:35Z",
        "changed_at": "2017-03-02T12:50:35Z",
        "email": "",

            ]
        },
        "attachments": []
    }]
}

NodeJS脚本如下：

'use strict'

const Hapi = require('hapi');
const Express = require('express');
const Request = require('request');
const Vision = require('vision');
const Handlebars = require('handlebars');
const _ = require('lodash');
const LodashFilter = require('lodash.filter');
const LodashTake = require('lodash.take');
const JSONStream = require('JSONStream');
const jQuery = require('jsdom');

const server = new Hapi.Server();

server.connection({
    host: '127.0.0.1',
    port: 3000,
    routes: {
        cors: {
            origin: ['*'],
            additionalHeaders: ['X-API-KEY']
        },

    }
});

server.register(Vision, (err) => {
    server.views({
        engines: {
            html: Handlebars
        },
        relativeTo: __dirname,
        path: './views',
    });
});

server.start((err) => {
    if (err) {
        throw err;
    }
    getJSON();
    console.log(`Server running at: ${server.info.uri}`);
});

function getJSON() {

    // URL and APIKEY ommitted for security reasons
    var as_host = '';
    var as_apiKey = ''
    var as_endpoint = '/api/public/v1/projects/';
    var as_projectId = '736';
    var as_endpointExt = '/submissions';
    var as_url = as_host + as_endpoint + as_projectId + as_endpointExt;

    var options = {
        url: as_url,
        headers: {
            'X-API-KEY': as_apiKey,

        },
        json: true
    };

    function callback(error, response, body) {
        if (!error && response.statusCode == 200) {         
            var jsonString1 = JSON.stringify(body);
            var jsonObject = JSON.parse(jsonString1);


            console.log("BODY2: " + jsonObject);

        }
    }
    Request(options, callback);
}

console.log("BODY2: " + jsonObject);输出BODY2: [object Object]这不是我想要的。当我从json: true的options变量中删除request时，它会输出JSON（或至少看起来像一个），但我仍然无法访问JSON中的键/值对。我需要特别访问JSON的data部分，其中包含需要切换到第二个远程REST API的相关数据集（只接受特殊格式，这就是为什么我不能简单地处理检索到的JSON到其他API）。我已经尝试了几个解决方案并在这里阅读了很多帖子，它们似乎都不适用于我（JSON.parse()，JSONStream.parse()，_.get()等等。非常感谢任何帮助！
