HTTPError处理Python3防火墙数据库

Question

当我进行授权调用Firebase时：

email = request.POST['email']
password = request.POST['password']
config = {
    "apiKey": "",
    "authDomain": "",
    "databaseURL": "",
    "storageBucket": ""
}
firebase = pyrebase.initialize_app(config)
auth = firebase.auth()
try:
    user = auth.create_user_with_email_and_password(email, password)
    user = auth.refresh(user['refreshToken'])
    request.session['user_uuid'] = user
    if user != "":
        print("You're logged in.")
        return redirect('')
    else:
        print("")

except requests.exceptions.HTTPError as e:
    print(e)

我收到以下答复：

"[Errno 400 Client Error: Bad Request for url: 
https://www.googleapis.com/identitytoolkit/v3/relyingparty/signupNewUser?
key=%20AIzaSyCm0XR9oECpQOBTp_iouf3RJTD-Nq0fuXg] {
"error": {
  "errors": [
{
  "domain": "global",
  "reason": "invalid",
  "message": "WEAK_PASSWORD : Password should be at least 6 characters"
 }
],
"code": 400,
"message": "WEAK_PASSWORD : Password should be at least 6 characters"
}
}"

我正在尝试解析来自响应的消息和代码，但是我始终得到一个可订阅的错误。我使用以下代码来解析响应：

data = e[-1]
data = (json.dumps(json.loads(data), sort_keys = True, indent = 4))
data = json.loads(data)
error = data['error']
error_message = error['message']
print(error_message)
context_dict = {
    'message': error_message
}

pyrebase引发更新的 exception；重新包装原始异常。

您可以得到该异常用.args属性包装的两个值。它是一个带有原始异常的元组，request_object.text值作为第二个。它是要解析的第二个值，或，您可以使用原始异常获取响应对象，并使用.json()让请求库进行解析。

except requests.exceptions.HTTPError as e:
    error_json = e.args[1]
    error = json.loads(error_json)['error']

或

except requests.exceptions.HTTPError as e:
    response = e.args[0].response
    error = response.json()['error']

老实说，我不太清楚项目为什么要这样做；原始异常已经包含了它们绑定的信息；例如，使用original_exception.response.text不是重新包装异常，而是生成相同的文本值。
