权限模型

\Permission Model

Node.js 权限模型是一种在执行期间限制对特定资源的访问的机制。API 存在于标志 --permission 之后,启用后将限制对所有可用权限的访问。

\The Node.js Permission Model is a mechanism for restricting access to specific resources during execution. The API exists behind a flag --permission which when enabled, will restrict access to all available permissions.

可用权限由 --permission 标志记录。

\The available permissions are documented by the --permission flag.

使用 --permission 启动 Node.js 时,通过 fs 模块访问文件系统、生成进程、使用 node:worker_threads、使用原生插件、使用 WASI 和启用运行时检查器的能力将受到限制。

\When starting Node.js with --permission, the ability to access the file system through the fs module, spawn processes, use node:worker_threads, use native addons, use WASI, and enable the runtime inspector will be restricted.

$ node --permission index.js
Error: Access to this API has been restricted
 at node:internal/main/run_main_module:23:47 {
 code: 'ERR_ACCESS_DENIED',
 permission: 'FileSystemRead',
 resource: '/home/user/index.js'
} 拷贝

允许访问生成进程和创建工作线程可以分别使用 --allow-child-process 和 --allow-worker 来完成。

\Allowing access to spawning a process and creating worker threads can be done using the --allow-child-process and --allow-worker respectively.

要在使用权限模型时允许原生插件,请使用 --allow-addons 标志。对于 WASI,请使用 --allow-wasi 标志。

\To allow native addons when using permission model, use the --allow-addons flag. For WASI, use the --allow-wasi flag.
