How to obtain request variables in TypeORM subscribers?

[seepine]

My oauth2 Middleware

app.use(async (c, next) => {
  const user = jwt.verify() // ....
  c.set("user", user)
  await next()
})

Any my typeorm

@EventSubscriber()
  class AutoPrimaryKeySubscriber implements EntitySubscriberInterface {
    async beforeInsert(event: InsertEvent<any>) {
      for await (const item of event.metadata.columns) {
        if (item.propertyName === 'createId') {
          // How to obtain the user variable set by the middleware here, and the variable should be independent for each request? 
          event.entity[item.propertyName] = user.id     
        }
      }
      return event
    }
}

const dataSourceOptions: DataSourceOptions = {
    type: db.type,
    host: db.host,
    port: db.port,
    username: db.username,
    password: db.password,
    database: db.database,
    synchronize: db.synchronize,
    entities: ['src/models/*.ts'],
    subscribers: [AutoPrimaryKeySubscriber]
  }

Like fastify can set request level var

fastify.decorateRequest('user')

And in typeorm of subscriber

event.entity[item.propertyName] = fastify.user?.id
