Django Rest -当身份验证失败时，我如何返回自定义json响应？

from rest_framework.exceptions import AuthenticationFailed
from rest_framework.views import exception_handler
from rest_framework.response import Response

class CustomAuthenticationFailed(AuthenticationFailed):
    def __init__(self, detail=None):
        if detail is not None:
            self.detail = detail
        else:
            self.detail = "身份验证失败。"

def custom_exception_handler(exc, context):
    response = exception_handler(exc, context)  # 调用Django Rest的默认异常处理器

    if isinstance(exc, CustomAuthenticationFailed):  # 检查异常类型是否为自定义的身份验证失败异常
        response.data = {  # 构建自定义JSON响应
            'error': True,
            'message': str(exc.detail)
        }

    return response

REST_FRAMEWORK = {
    'EXCEPTION_HANDLER': 'your_project.custom_auth_responses.custom_exception_handler',
    # 其他设置项...
}
