如何将路由配置参数传递给 hapijs 插件？

Question

我正在尝试定义可由插件检查的附加路由参数。

插件看起来像这样：

import { Server, Request } from "@hapi/hapi"

declare module "@hapi/hapi" {
  export interface PluginSpecificConfiguration {
    permissions: string[]
  }
}

const permissions = () => {
  return {
    plugin: {
      name: "permissions",
      register: async (app: Server) => {
        app.ext("onRequest", (request: Request, h) => {
          Log.info(
            `permissions: ${request.route.settings.plugins?.permissions}`,
          )
          return h.continue
        })
      },
    },
  }
}

export default async ({ app }: { app: Server }) => {
  app.register(permissions())
}

我的路线：

export default ({ app }: Readonly<{ app: Server }>) => {
  app.route({
    method: "GET",
    options: {
      auth: "session",
      handler: async ({ auth, query }) => {
        // omitted
      },
      plugins: {
        permissions: ["permission 1"],
      },
    },
    path: "/users",
  })
}

但是，当插件收到请求时，permissions 字段总是 undefined。

出于某种原因，插件信息未通过 onRequest 事件传递。但是它用于 onPreHandler 事件，因此我能够进行更改：

app.ext("onPreHandler", (request: Request, h) => {
    Log.info(
        `permissions: ${request.route.settings.plugins?.permissions}`,
    )
    return h.continue
})
