“开发人员对App Engine上的文件系统具有只读权限”是否正确？ [英] Is it correct that "Developers have read-only access to the filesystem on App Engine"?

问题描述

根据这篇关于Google App Engine的Wikipedia文章：

开发人员对App Engine上的文件系统具有只读访问权限

我听说过允许上传的App Engine应用程序，Google也销售额外的存储空间 - 如果是这样，这个声明是不是显示不正确？

额外的存储不一定在文件系统中，而在存储本身中。

从 Google App Engine 页面：

App Engine应用程序无法写入文件系统。应用程序必须使用App Engine数据存储来存储持久性数据。从文件系统读取是允许的

According to this Wikipedia article on Google App Engine:

Developers have read-only access to the filesystem on App Engine.

I have heard of App Engine apps that allow uploads and Google also sells additional storage - if so, wouldn't this statement appear to be incorrect?

解决方案

No.

Those apps would likely store the uploaded data into the store directly rather than the filesystem.

The additional storage is not necessarily in the filesystem but in the storage itself.

From this Google App Engine page:

An App Engine application cannot [...] write to the filesystem. Applications must use the App Engine datastore for storing persistent data. Reading from the filesystem is allowed
