使用fastify-session和fastify-webockets时，如何访问会话？

Question

当我在我的应用程序中同时使用fastify-websocket和fastify-session时，我遇到了一个问题。

  fastify.get( myWebsocketPath, websocket: true },
               async (connection, rawRequest) => {

    console.log(`request for websocket connection`)
    if( request.session.authenticated ) {
      myApi( connection.socket )
    }
  })

除非这会失败，因为我只有rawRequest，而不是用会话修饰的常规请求。

似乎要为它获取一个外部句柄，您需要自己设置会话存储。最好使用定制存储，但为了简单起见，在本例中我将使用fastify-session提供的内置存储。

let fastifySession = require(`fastify-session`)
let mySessionStore = new fastifySession.MemoryStore /// TODO: customize
let options = { store: mySessionStore, secret: `itsasecrettoeverybody`,  cookieName: `sessionId`, expires: 3600000, cookie:  { secure: false } }
fastify.register(fastifySession, options)

// ...

const routes = async (fastify, options) => {
  fastify.get( myWebsocketPath, websocket: true },
               async (connection, rawRequest) => {

    /// Retrieve the session
    let cookies = rawRequest.headers.cookie.split(`;`)
    for( c of cookies ) {
      if( c.startsWith(`sessionId=`) ) {

        /// Get SessionID from the cookie
        let sessionID = c.substring(10).trim()
        sessionID = sessionID.substring( 0, sessionID.indexOf(`.`) )

        /// Collect session and check the authentication state.
        mySessionStore.get( sessionID, ( o, session ) => {
          if( session != null && session.authenticated == true ) {
            myApi( connection.socket )
          }
        })
        break
      }
    }
  })
}
