Firebase托管的身份验证 [英] Authentication for firebase hosting

问题描述

我在Firebase托管上托管了一个静态应用程序，其后端也在Firebase上(使用firebase JS api进行通信).我想向该网站的所有页面添加一个简单的身份验证页面，以便只有我想要的用户才能访问该网站.这可能吗?

I have a static app hosted on Firebase hosting whose backend is also on Firebase(communicating using firebase JS api). I want to add a simple auth page to all pages of this website so that only users I want can access this site. Is this possible?

看了看文档，却没有找到任何对我有帮助的东西.

Looked at the docs but didn't find anything that helps me in this regard.

推荐答案

您可以使用Firebase函数和Express调用来做到这一点.将所有静态文件放入名为functions/admin的文件夹，然后将此函数放入functions/index.js:

You can do this using Firebase Functions, and an Express call. Put all of your static files into a folder named functions/admin and put this function into functions/index.js:

exports.admin = functions.https.onRequest((req, res) => {
  const url = req.originalUrl ? req.originalUrl : '/index.html'  // default to index.html
  res.sendfile('admin' + url)
})

然后，向功能服务器请求/admin/*的请求将提供相同名称的文件.

Then, a request to your functions server for /admin/* will serve up the file of the same name.

如果要添加授权，请尝试以下操作:

If you want to add authorization, try this:

exports.admin = functions.https.onRequest(async (req, res) => {
  const url = req.originalUrl ? req.originalUrl : '/index.html'
  const user = await get_user(req)  // get the current user
  if (user && user.is_admin)        // is current user an admin?
    res.sendfile('admin' + url)
  else {
    res.status(403).send(null)
  }
})

您将必须定义get_user()，以便它返回带有is_admin字段的用户对象.

You will have to define get_user() so it returns a user object with an is_admin field.
