“web-request”包的依赖问题。无法解析'stream'、'tls'、'zlib'、'path'、'net'、'https'、'http'、'fs'、'crypto'

Question

在开发 web/node.js 应用程序方面，我是一个初学者（如果我解释得不够好，请见谅），现在我正在研究一个角度和角度材料项目。我认为这不是重点...

我的应用程序是用 typescript 编写的 - 但是我使用的是编译为 javascript 的 typescript 库。该库使用“网络请求”。到目前为止，我只使用该库中的一个文件（但该文件使用同一库中的其他文件），我将通过 import { MyClass } from '../../lib/file_1' 和 myclass = new MyClass(); 将其命名为“file_1.js”。

file_1.d.ts 和 file_1.js.map 也存在，我只能假设它们已正确实施。事实上，我已经从我之前工作过的一个 react 项目中复制粘贴了这个库，它在那里工作得很好。

file_1.js 仅在两种情况下使用此库：因此具有：

const WebRequest = require("web-request");
let response = yield WebRequest.get(openUri, requestOptions);
let response = yield WebRequest.post(postUri, requestOptions, jsonBody);

我非常有信心图书馆本身是健全的。当尝试通过 ng serve 运行我的服务器时，我遇到了很多问题，即 web-request 的依赖关系没有得到解决：

我尝试在此处应用 snorberhuis 建议的解决方案：Angular 6 many Can't resolve errors (crypto, fs, http, https, net, path, stream, tls, zlib)，将其添加到我的 package.json：

  "browser": {
    "http": false,
    "https":false,
    "net": false,
    "path": false,
    "stream": false,
    "tls": false,
    "crypto": false,
    "fs": false,
    "zlib": false
  }

服务器启动时没有问题 - 但浏览器窗口仍然是空白，控制台中出现错误：

问题在于“web-request”模块不是在浏览器中工作，而是在节点服务器上工作。您需要使用不同的包来实现您需要实现的目标。
