javascript - 从获取响应 Javascript/Nodejs 创建缓冲区对象

问题描述

我正在使用 fetch 发送 API 请求并返回 JSON 响应。我很难创建缓冲区对象，因此我可以像处理/解析 JSON 响应一样，如果它是包含 JSON 对象的本地文件或变量。以下是我的获取代码（有效）：

const fetch = require("node-fetch");


const asset = 'Build_Artifacts'
const url2 = 'http://localhost:8081/service/rest/v1/components?repository='
const myHeaders = {
    "Authorization": "Basic token",
    "Content-Type": "application/json",
};

const requestOptions = {
    method: 'GET',
    headers: myHeaders,
    redirect: 'follow'
}

const getData = async () => {
    const res = await fetch(url2 + asset, requestOptions);
    const data = await res.text()
    return data
}

getData()   // Returns JSON response

从阅读： https ://developer.mozilla.org/en-US/docs/Learn/JavaScript/Client-side_web_APIs/Fetching_data 如何将 Node.js 流的内容读入字符串变量？ https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch

我认为我应该创建一个缓冲区对象来将获取响应放入其中。完成此操作后，我应该能够继续操作响应内容。我做了一些新手尝试，并意识到我离得很近。以下是基于上述阅读的新手尝试：

getData().then(data.arrayBuffer().then(function(buffer) {
    //do something with the buffered object
}))

更新我使用 res.text() 而不是 res.json() 因为我在使用 res.json() 时的获取响应不会作为经过验证的 JSON 输出返回。见下文：

//Output when using res.text():

从上面可以看出 res.text() 提供了经过验证/准确的 JSON，而 res.json() 没有。没有准确的 JSON 会使解析变得更加困难。

结束更新

我离得到这个很近吗？谁能指出我正确的方向或给我一个从我可以使用的提取请求创建缓冲对象的简单示例？任何和所有的帮助表示赞赏。
