权限模型


🌐 Permission Model

稳定性: 1.1 - 处于活跃开发中

Node.js 权限模型是一种在执行期间限制访问特定资源的机制。API 位于标志 --experimental-permission 之后,当启用时,它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 --experimental-permission which when enabled, will restrict access to all available permissions.

可用的权限由 --experimental-permission 标志记录。

🌐 The available permissions are documented by the --experimental-permission flag.

在使用 --experimental-permission 启动 Node.js 时,通过 fs 模块访问文件系统、创建进程、使用 node:worker_threads、使用本地插件、使用 WASI 以及启用运行时调试器的能力将受到限制。

🌐 When starting Node.js with --experimental-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 --experimental-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'
} 

允许访问以生成进程和创建工作线程可以分别使用 --allow-child-process--allow-worker 来实现。

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

在使用权限模型时允许本地插件,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.
