How to manually save session from ctx.session?

[niftylettuce]

e.g. I want to save session in my error handler middleware, how do I do that?

I'm having a similar issue--unable to save the session when using a socket.io listener

Can read and write:

router.get('/count', ctx => {
    var session = ctx.session;
    session.count = session.count || 0;
    session.count++;
    ctx.body = session.count;
})

Can only read:

io.on('test', (ctx, data) => {
    console.log('test get count', ctx.session.count)
    var session = ctx.session;
    session.count = session.count || 0;
    session.count++;
})

Edit: turns out this has a simple fix. The second fetch will work. Still looking for socket.io workaround

Just as a warning for others, it appears that koa-generic-session does not allow modification to session from a fetch call.

browser:

fetch('/count', {
    method: 'POST',
    headers: {
        count: 1,
    }
})
fetch('/count', {
    method: 'POST',
    headers: {
        count: 2,
    },
    credentials: 'include'
})

server:

router.post('/count', (ctx) => {
    var session = ctx.session
    console.log('sesh1', ctx.session)
    session.count = session.count || 0
    session.count = session.count + ctx.request.header.count
    console.log('sesh2', ctx.session)
    ctx.status = 200   
});

im having the same read only issue in websockets while using koa-session and koa-websocket. tried switching to generic-session using a redis store and had the same issue.

@tbenst did you ever find a solution to this?

@hedgerh haven't tried it yet but this appears to outline a solution: http://stackoverflow.com/questions/26643370/get-user-id-socket-io-passport-koa.

If you do try it, please do post if it works and/or the code, cheers!

Edit: also, if you only need to read this works: LnsooXD/koa-socket-session#1 (comment). May be able to modify this code for writing to session, haven't looked into it yet
