python - 用于帐户创建和登录的Firebase错误处理-Pyrebase

Question

我正在尝试处理用户注册或登录我的应用程序时出现的错误。我要处理的第一个错误是用户尝试使用数据库中已存在的电子邮件创建帐户时。我得到以下HTTPError:

 requests.exceptions.HTTPError: [Errno 400 Client Error: Bad Request for url: https://www.googleapis.com/identitytoolkit/v3/relyingparty/signupNewUser?key=] {
   "error": {
     "code": 400,
     "message": "EMAIL_EXISTS",
     "errors": [
       {
         "message": "EMAIL_EXISTS",
         "domain": "global",
         "reason": "invalid"
       }
     ]
   }
 }

我想在下面访问"message": "EMAIL_EXISTS"值，但是我不确定该怎么做。我添加了以下代码，但产生以下错误:

     error_message = error["error"]["message"]
 TypeError: 'HTTPError' object is not subscriptable

import requests
import pyrebase

class CreateAccount():

    def create_account(self):

        try:
            auth.create_user_with_email_and_password(self.email, self.password)

        except requests.exceptions.HTTPError as error:
            print(error)
            error_message = error["error"]["message"]
            print(error_message)

经过大量搜索后，我找到了此问题的答案:

        except requests.HTTPError as e:
            error_json = e.args[1]
            error = json.loads(error_json)['error']['message']
            if error == "EMAIL_EXISTS":
                print("Email already exists")
