reactjs - 通过加密反应原生应用程序构建错误

问题描述

While trying to resolve module `crypto` from file `C:\Users\munge\SemaApp\node_modules\request\lib\helpers.js`, the package `C:\Users\munge\SemaApp\node_modules\crypto\package.json` was successfully found. However, this package itself specifies a `main` module field that could not be resolved (`C:\Users\munge\SemaApp\node_modules\crypto\index.js`. Indeed, none of these files exist:

  * C:\Users\munge\SemaApp\node_modules\crypto\index.js(.native|.android.ts|.native.ts|.ts|.android.tsx|.native.tsx|.tsx|.android.js|.native.js|.js|.android.jsx|.native.jsx|.jsx|.android.json|.native.json|.json)

我的 react native 应用程序在使用 web（expo 小吃）打开时可以正常工作。但是当我尝试通过 apk 类型构建我的应用程序时发生了上述错误。它说模块加密存在问题，但我什至没有在我的代码中使用加密。有什么问题，我该如何解决？

解决方案

Crypto 模块与 request 相关，已弃用。使用 fetch 而不是 request。“https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch”展示了如何使用 fetch。
