尝试从RapidAPI提取的结果中获取数据

编程问答 2022-06-04

问题描述

我对Web编程非常陌生，需要帮助。

我正在使用Node.js通过RapidAPI获取数据 提取的结果以数组的形式向我返回了JSON解析格式。 但是，如果我要提供索引，它将返回字母，而不是我想要查看的项目。

下面是我要获取Apple结果的代码： 

const express = require('express');
const bodyParser = require('body-parser');
const http = require("https");

const app = express();
app.use(bodyParser.urlencoded({extended:true}));

app.get("/",function(request,response){
    response.sendFile(__dirname + "/index.html");
});

app.post("/",response){
const options = {
    "method": "get","hostname": "rapidapi.p.rapidapi.com","port": null,"path": "/income-statement/AAPL?apikey=demo","headers": {
        "x-rapidapi-key": "895157e459mshecb81dbe427f124p1fe70cjsn772a488898eb","x-rapidapi-host": "financial-modeling-prep.p.rapidapi.com","useQueryString": true
    }
};

const req = http.request(options,function (res) {
    const chunks = [];
    
    if (res.statusCode === 200) {
        console.log("Success");
    } else {
        console.log("Fail");
    }

    res.on("data",function (chunk) {
        console.log(chunk.toString('utf-8')[23]);
        chunks.push(chunk);
    });

    res.on("end",function () {
        const body = Buffer.concat(chunks); 

    });
});    
req.end();
});

“块”的日志结果：

}，...]

问题：如果我特别想从响应中访问“ netDebt”之类的特定字段，我将如何访问它？

ex）chunck [0]返回类似“ l”的字母。我想我不太清楚它的结构。 我在想像块[0] [“ netDebt”]

谢谢
