“web-request” package 的依賴關系問題。 無法解析 'stream'、'tls'、'zlib'、'path'、'net'、'https'、'http'、'fs'、'crypto'

Question

在開發 web/node.js 應用程序方面，我是初學者（如果我對自己的解釋不夠好，請道歉），現在我正在研究 angular 和 angular 材料項目。 然而我認為這不是重點……

我的應用程序是用 typescript 編寫的 - 但是我使用的是編譯為 javascript 的 typescript 庫。 該庫使用“網絡請求”。 到目前為止，我只使用該庫中的一個文件（但該文件使用同一庫中的其他文件），我將通過import { MyClass } from '../../lib/file_1'和myclass = new MyClass(); .

file_1.d.ts和file_1.js.map存在，我只能假設它們已正確實施。 事實上，我已經從我不久前從事的一個反應項目中復制粘貼了這個庫，它在那里工作得很好。

file_1.js 僅在兩種情況下使用此庫：因此具有：

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

我非常有信心圖書館本身是健全的。 當嘗試通過ng serve運行我的服務器時，我遇到了很多問題，即 web-request 的依賴關系沒有得到解決：

I tried applying the solution suggested by snorberhuis here: Angular 6 many Can't resolve errors (crypto, fs, http, https, net, path, stream, tls, zlib) by adding this to my package.json:

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

然后服務器啟動沒有問題 - 但瀏覽器 window 仍然是空白，控制台中出現錯誤：

問題是“web-request”模塊不是為了在瀏覽器中工作，而是在節點服務器上工作。 您需要使用不同的 package 來實現您需要的目標。
