如何在Angular应用程序部署中安全地管理环境变量

我有一个 environment.ts 文件

export const environment = { token: '345' };

和一个 enviroment.development.ts 文件

export const environment = { token: '123' };

两者都在公共GitHub回购上。我想部署一个应用程序,并将令牌值设置为真正的键值,但在Netlify或Vercel上使用环境变量不起作用,因为我为项目设置了环境变量。我不想在我的应用程序的任何部分写下真正的访问令牌。如何部署应用程序并将伪造的代币值更改为真实值?如果我把真正的价值放在 src/environments/environment.development.ts 它将是公开的,但我必须这样做,因为它是Netlify或Vercel获取代码的地方。

如果我加上:

  production: true,
  token: '345',

这些值仍然没有改变。
