Question

是否可以检查是否通过云功能验证了电子邮件即，如果我有该用户的uid，可以检查该特定用户的电子邮件是否经过验证。在我的用例中，我需要确保在执行交易之前已验证电子邮件。我要在服务器端进行检查

样本云功能：

exports.executeTransaction = functions.https.onCall((data,context)=>{ 

const userid = context.auth.uid 

//Check if email is verified
//I want to use context variable to somehow extract whether email is verified. Is there a way to do it ?
//Execute Transaction if email is verified
})

Answer 1

没关系，我设法弄清楚了。

遇到类似问题的人，请参见以下内容：

exports.executeTransaction = functions.https.onCall((data,context)=>{ 
const userid = context.auth.uid 
//Check if email is verified
return admin.auth().getUser(context.auth.uid).then(user => {
//Check if email verified
  if(user.emailVerified)
  {
return "Verified"
}
else{
console.log("User Email not verified")
return "Not Verified"
}
}).catch(function(err){
  console.log(err)
  throw new functions.https.HttpsError('Error Validating', err.message, err)
})
})

根据文档，上下文包括decodedIdToken，该文本已经包含email_verified字段。

因此，您所需要做的就是：

exports.executeTransaction = functions.https.onCall((data, context) => {
  const { token } = context.auth;
  if (!token.firebase.email_verified)
    throw new functions.https.HttpsError(
      "failed-precondition",
      "The function must be called while authenticated."
    );

  // ...do stuff
})
