使用自定义令牌进行 Firebase 身份验证 [英] Firebase authentication with custom token

问题描述

我有一个 firebase 项目，我试图从我的 rails 服务器进行身份验证，并使用库 ruby​​-jwt 创建自定义令牌，正如文档中所说，但我一直收到相同的错误:

I have a firebase project which Im trying to authenticate from my rails server creating a custom token with the library ruby-jwt as it says on the docs, but i keep getting the same error:

auth/invalid-custom-token，自定义token格式不正确.请检查文档.

auth/invalid-custom-token, The custom token format is incorrect. Please check the documentation.

credentials.json来自我在google console中创建的服务账号，uid是从前端发送到api的.

The credentials.json is from the service account I made in google console, uid is sent from the front end to the api.

def generate_auth_token(uid)
  now_seconds = Time.now.to_i
  credentials = JSON.parse(File.read("credentials.json"))
  private_key = OpenSSL::PKey::RSA.new credentials["private_key"]
  payload = {
      :iss => credentials["client_email"],
      :sub => credentials["client_email"],
      :aud => 'https://identitytoolkit.googleapis.com/google.identity.identitytoolkit.v1.IdentityToolkit',
      :iat => now_seconds,
      :exp => now_seconds+(60*60), # Maximum expiration time is one hour
      :uid => uid.to_s,
      :claims => {:premium_account => true}
    }
  JWT.encode(payload, private_key, 'RS256')
end

在 jwt.io 中是这样的

it looks like this in jwt.io

{
  "iss": "[e-mail]",
  "sub": "[e-mail]",
  "aud": "https://identitytoolkit.googleapis.com/google.identity.identitytoolkit.v1.IdentityToolkit",
  "iat": 1486824545,
  "exp": 1486828145,
  "uid": "4",
  "claims": {
     "premium_account": true
   }
}

推荐答案

我找到了一种更好的身份验证方法，我只是发送 firebase 给你的令牌，并使用我需要的信息在 Rails 上验证它，仅此而已.

I found a better way to authenticate, I'm just sending the token that firebase gives you and verifying it on rails with the information I need and that's it.
