【问题描述】:
我是网络编程的新手,我需要帮助。
我正在使用 Node.js 通过 RapidAPI 获取数据 获取的结果以数组中的 Parsed JSON 格式返回给我。 但是,如果我要给出一个索引,它会返回字母而不是我想查看的项目。
以下是我必须获取 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("/", function(request, 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特定字段,例如“netDebt”,我将如何访问它?
ex) chunck[0] 返回一个类似“l”的字母。我想我不清楚它的结构。 我在想类似 chunk[0]["netDebt"]
谢谢,
