Python RawPostDataException:从请求读取后无法访问正文'；s数据流

我在谷歌云上托管了一个网站，我让所有的东西都运行得很好，然后突然我开始出现这个错误

我不知道这意味着什么，没完没了的谷歌搜索并没有解决我的问题

以下是可能相关的代码：

视图.py

        account = authenticate(email=email, password=password)

        if account is not None:
            if account.is_active:
                login(request, account)

                serialized = AccountSerializer(account)

发生这种情况是因为您试图从

body

---

使用->

data=json.loads（request.data）

嘿，谢谢你的回复，但我已经搞定了！它不起作用，因为我发现了一个小错误，即使我已经登录，我仍然可以访问登录页面，因此错误是由于尝试再次登录造成的。我修复了这个问题，如果尝试访问登录页面，请重定向到主页

使用

request.data

而不是

request.body

---

请求。数据

不会再次读取数据流。
