使用 Forge 模块时未定义错误 window
Error window is not defined when using Forge module
我是 NativeScript 的新手，我正在尝试在项目中进行加密。
我打算使用 Forge 模块并使用 npm install --save node-forge 来安装锻造。但是一旦我添加了 import 语句 (var forge = require("node-forge");
) 在 home-page.js 文件中出现此错误。window 未定义

有人知道这个问题吗？
您可能只能在 NativeScript 中使用 CommonJS 模块。任何浏览器/节点特定的功能都不会在 NativeScript 环境中工作。
此包使用 window.forge 来保持全局引用，window 确实是浏览器特定的功能。但由于它仅用于存储全局引用，所以一个技巧是在加载此包之前创建全局 window 对象。
global.window = {};
但是这个包似乎还使用了其他浏览器特定的功能，例如加载 SWF/ActionScript，这些没有任何解决方法。您必须为 iOS / Android 找到相同的本地等效项。
