【问题描述】：

我正在尝试使用 vuejs 和 typescript 在我的项目中实施加密。我在 .vue 文件中成功实现了它，但是当我尝试将加密写入 typescript 类时，mocha 测试会运行它，但是当我尝试在浏览器中编译并打开它时，我在控制台中收到一个 javascript 错误：

app.js:128620 Uncaught ReferenceError: require is not defined
at Object.crypto (app.js:128620)
at __webpack_require__ (app.js:20)

at Module../resources/js/Components/Includes/Login.vue? 
vue&type=script&lang=js& (app.js:124322)
at __webpack_require__ (app.js:20)

app.js中的标记行是：

module.exports = require("crypto");

我已经在打字稿文件中尝试了不同的导入“策略”，例如：

import * as crypto from "crypto";
import crypto from "crypto";
var crypto = require("crypto");

并且还在 webpack.mix.js 中添加这个

"node": 
        fs: "empty",
        crypto: true,
        http: true,
        https: true,
        os: true,
        vm: true,
        stream: true,
        path: true
    ,

但是没有用。

Crypter.ts

import crypto from "crypto";

export default class Crypter 

    public constructor() 
    

    public static publicEncrypt(data: JSON, publicKey: string): string
        let dataStr = JSON.stringify(data);
        let dataB64 = Buffer.from(dataStr).toString("base64");
        var buffer = Buffer.from(dataB64);
        return crypto.publicEncrypt(publicKey, buffer).toString("base64"); 
    

tsconfig.json

        ,

    "exclude": [

        "**/*.spec.ts"
    ],
    "files": [
        "./node_modules/@types/node/index.d.ts"
      ]

我认为错误是由错误的编译或其他错误配置引起的。

【参考方案1】：

您无法在 Web 应用程序中访问 nodejs 加密模块。 Node.js 使用相同的 javascript 语法，但不在浏览器中运行。

您可能需要安装另一个加密库，例如 crypto-js，您可以使用 npm install crypto-js 进行安装。可能还有很多其他库可供您选择 (some ideas)
