問題描述
這是我的代碼:
var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
var xhr = new XMLHttpRequest();
xhr.open("GET", "http://URL")
xhr.setRequestHeader("Content-Type: application/json", "Authorization: Basic //AuthKey");
xhr.send();
我收到錯誤:
Cannot find module 'xmlhttprequest'
當(dāng)我刪除第一行時，我得到:
When I remove the first line, I am getting:
XMLHttpRequest is not defined
我到處搜索，人們到處都提到了 Node.js 的問題，但我的 Node 安裝是正確的，所以我不確定問題是什么.
I have searched all over and people have mentioned a problem with Node.js here and there but my installation of Node was correct so I'm not sure what the issue is.
推薦答案
XMLHttpRequest 是網(wǎng)絡(luò)瀏覽器中的內(nèi)置對象.
XMLHttpRequest is a built-in object in web browsers.
它不與 Node.js 一起分發(fā).http 模塊 是從 Node 發(fā)出 HTTP 請求的內(nèi)置工具.
It is not distributed with Node. The http module is the built-in tool for making HTTP requests from Node.
大多數(shù)從節(jié)點(diǎn)發(fā)出 HTTP 請求的人都使用具有更友好 API 的第三方庫.兩個流行的選擇是 Axios(用于 Node.js 和瀏覽器)和 node-fetch (它實(shí)現(xiàn)了瀏覽器內(nèi)置的 fetch API，是XMLhttpRequest 的現(xiàn)代替代品.
Most people making HTTP requests from node use a third party library with a friendlier API. Two popular choices are Axios (for use both in Node.js and browsers) and node-fetch (which implements the fetch API which is built into browsers and is a modern replacement for XMLhttpRequest.
如果你真的想在 Node.js 中使用 XHR，那么有幾個第三方實(shí)現(xiàn).xmlhttprequest (似乎沒有維護(hù))和 xhr2(今年有更新).
If you really want to use XHR in Node.js then there are a couple of third party implementations. xmlhttprequest (which seems to be unmaintained) and xhr2 (which has had an update this year).
用 npm 安裝，
Install it with npm,
npm install xhr2
現(xiàn)在你可以在你的代碼中require它.
var XMLHttpRequest = require('xhr2');
var xhr = new XMLHttpRequest();
