文件系统权限

¥File System Permissions

默认情况下，权限模型通过 node:fs 模块限制对文件系统的访问。它不能保证用户无法通过其他方式（例如通过 node:sqlite 模块）访问文件系统。

¥The Permission Model, by default, restricts access to the file system through the node:fs module. It does not guarantee that users will not be able to access the file system through other means, such as through the node:sqlite module.

要允许访问文件系统，请使用 --allow-fs-read 和 --allow-fs-write 标志：

¥To allow access to the file system, use the --allow-fs-read and --allow-fs-write flags:

$ node --experimental-permission --allow-fs-read=* --allow-fs-write=* index.js
Hello world!
(node:19836) ExperimentalWarning: Permission is an experimental feature
(Use `node --trace-warnings ...` to show where the warning was created)

两个标志的有效参数是：

¥The valid arguments for both flags are:

  • * - 分别允许所有 FileSystemRead 或 FileSystemWrite 操作。

    ¥* - To allow all FileSystemRead or FileSystemWrite operations, respectively.

  • 以逗号 (,) 分隔的路径分别仅允许匹配 FileSystemRead 或 FileSystemWrite 操作。

    ¥Paths delimited by comma (,) to allow only matching FileSystemRead or FileSystemWrite operations, respectively.

示例：

¥Example:

  • --allow-fs-read=* - 它将允许所有 FileSystemRead 操作。

    ¥--allow-fs-read=* - It will allow all FileSystemRead operations.

  • --allow-fs-write=* - 它将允许所有 FileSystemWrite 操作。

    ¥--allow-fs-write=* - It will allow all FileSystemWrite operations.

  • --allow-fs-write=/tmp/ - 它将允许 FileSystemWrite 访问 /tmp/ 文件夹。

    ¥--allow-fs-write=/tmp/ - It will allow FileSystemWrite access to the /tmp/ folder.

  • --allow-fs-read=/tmp/ --allow-fs-read=/home/.gitignore - 它允许 FileSystemRead 访问 /tmp/ 文件夹和 /home/.gitignore 路径。

    ¥--allow-fs-read=/tmp/ --allow-fs-read=/home/.gitignore - It allows FileSystemRead access to the /tmp/ folder and the /home/.gitignore path.

也支持通配符：

¥Wildcards are supported too:

  • --allow-fs-read=/home/test* 将允许读取与通配符匹配的所有内容。例如：/home/test/file1 或 /home/test2

    ¥--allow-fs-read=/home/test* will allow read access to everything that matches the wildcard. e.g: /home/test/file1 or /home/test2

传递通配符 (*) 后，所有后续字符都将被忽略。例如：/home/*.js 的工作方式与 /home/* 类似。

¥After passing a wildcard character (*) all subsequent characters will be ignored. For example: /home/*.js will work similar to /home/*.

初始化权限模型时，如果指定的目录存在，它将自动添加通配符 (*)。例如，如果 /home/test/files 存在，它将被视为 /home/test/files/*。但是，如果目录不存在，则不会添加通配符，并且访问将仅限于 /home/test/files。如果要允许访问尚不存在的文件夹，请确保明确包含通配符：/my-path/folder-do-not-exist/*。

¥When the permission model is initialized, it will automatically add a wildcard (*) if the specified directory exists. For example, if /home/test/files exists, it will be treated as /home/test/files/*. However, if the directory does not exist, the wildcard will not be added, and access will be limited to /home/test/files. If you want to allow access to a folder that does not exist yet, make sure to explicitly include the wildcard: /my-path/folder-do-not-exist/*.
