Question

当我进行授权时，请使用以下命令调用Firebase：

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)

我收到此回复：

"[Errno 400 Client Error: Bad Request for url:

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"
}
}"

我试图解析响应中的消息和代码，但我一直收到可订阅的错误。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引发了更新requests.HTTPError exception;重新包装原始异常。

您可以使用.args属性获取该异常包含的两个值。它是原始异常的元组，第二个是request_object.text值。这是您要解析的第二个值，或您可以使用原始异常来获取响应对象，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']

说实话，我不太清楚为什么这个项目会这样做;原始异常已包含他们捆绑的信息;例如而不是重新包装异常，使用original_exception.response.text生成相同的文本值。
