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回购中.我想部署一个应用程序并将令牌值设置为真正的key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它们.我不想在应用程序的任何部分中写入真正的访问令牌.如何部署应用程序并将假 token 价值更改为真实价值？如果我将实际值设为src/environments/environment.development.ts，它就会公开，但我必须这样做，因为它是Netlify或Vercel获取代码的地方.

如果我添加:

  production: true,
  token: '345',

价值观仍然没有改变.
