Django Rest框架自定义错误格式

def custom_exception_handler(exc, context):
    # 调用DRF默认的异常处理函数获取响应
    response = exception_handler(exc, context)

    # 如果DRF已经处理了异常，返回其响应
    if response is not None:
        # 自定义错误格式
        custom_response_data = {
            'error_code': response.status_code,

            'details': response.data
        }
        return Response(custom_response_data, status=response.status_code)

    # 如果DRF没有处理异常，返回一个通用的错误响应
