【问题描述】：

当他们注册我的应用程序时，我正在尝试在我的平台中创建一个新用户。我希望他们输入他们的详细信息并将其发送到服务器以创建帐户，以便他们可以登录然后接收令牌。每当我使用邮递员发送凭据时，我都会收到此错误：

"detail": "未提供身份验证凭据。"

这是我目前所拥有的：

        user.set_password(password)
        user.save()
        return user

【参考方案1】：

这是因为您的全局 DRF 设置也应用于 createApp_user 视图。 您需要做的是，通过相应的装饰器为您的视图提供空的permission_classes 和authentication_classes 设置，如下所示

from rest_framework.decorators import api_view, authentication_classes, permission_classes


@api_view(['POST', ])
@authentication_classes(())
@permission_classes(())
def createApp_user(request):
    ...
    # your rest of the code
