Hi,I add koa-session2 Middleware,but when use session ,make error

[soulxy]

I followed your demo to add my middleware, found some problem.

my code:

• app.js

  //if the following ,I cannt view my page; app.use(session({store:new Store()}))

  app.use(convert(session({store: new Store()}))); //the same question

  // so,I have to write like this... , maybe some problem?

  app.use(async (ctx, next) => { session({ store: new Store() }); await next(); });

• user.js

  let result = {......};

  ctx.session.view = result;

  error

@soulxy

koa-session2 has already supported koa2, so you do not need to convert it, just use like this

app.use(session({store:new Store()}))

do not use convert middleware

[soulxy]

I known it,but server response timeout by your demo . So I have to use async/await, Service can respond, while Cannot set property 'view' of undefined .... I am a new koa ,use convert ,just try

[soulxy]

Sorry,Sorry ...I did a very foolish thing, forgot to start redis, then faced to anther error

@soulxy It seems an error in your router file users.js, maybe you can check E:\mywork\koa2.0\routers\users.js and find it. :)

[soulxy]

@Secbone in users.js , I just write ctx.session.userobj = '...' ... I tried my best to find question, but just find console.log('typeof session', typeof ctx.session) , print session is string . And I try to modify your files , Unfortunately, does not find a solution

[Secbone]

@soulxy Could you show me the users.js file ? I think there is something wrong in the userobj

[soulxy]

I writed it in jsbin... app.js users.js

[Secbone]

@soulxy Could you also show me the store.js file? I suspect there may have a problem in set method.

[soulxy]

I copy yours store.js

[Secbone]

@soulxy It seems good, I don't know what's wrong with your code, so I wrote a test for the custom store, and it works well. Maybe you can pull the repo and check it. Commit detail

[soulxy]

@Secbone I resolve this issue :) ~~ There are some issues in your get function of Store.js... At first time, typeof ctx.session is object,But when you got this type second time, it became string.Since reading redis's value without parsing, "[object object]"　appears

[Secbone]

@soulxy Good! I just thought somebody's session was not a object, maybe a string, so I didn't check the type of it. How do you think if I check the type?

[soulxy]

?? I just parse this value in get function of Store.js , will be fine :)
