Hello, I’m doing my Database course project using Genie as the back-end server, and I’m wondering how to set and save the session. And my efforts are as follows:

```julia
route("/api/login") do 
  uid = haskey(@params, :id) ? @params(:id) : ""
  password = haskey(@params, :password) ? @params(:password) : ""
  res = UsersController.checkLogin(uid, password, @params)
  println(@params[:SESSION])
  return res
end

```

```julia
  function checkLogin(uid, password, params)
    user = find(User, where("uid = ?", uid) + where("password = ?", password))
    ( (! haskey(params, Genie.PARAMS_SESSION_KEY) || params[Genie.PARAMS_SESSION_KEY] === nothing) ) &&
    (Sessions.start(params[:REQUEST], params[:RESPONSE], params))

    sess = params[:SESSION]
    if length(user) != 0
      return Dict("code" => 1, "msg" => "error!") |> json
    else
      Genie.Sessions.set!(sess, :uid, uid)
      # println(params[:SESSION], "\n\n\n", params)
      return Dict("code" => 0, "msg" => "success!") |> json
    end
  end

```

And I can print the `@params[:SESSION]` in the `route`.  
However, when the browser makes a new request and I want to capture the user name in session, error occures that the `@params` does not have the key.  
And I wonder how to use that properly. And in django framework, I know that I can simply use `request.session['uid'] = 'someid'` and get the session in the same way.  
BTW, I notice that the `Genie.Sessions.session` function has some bugs that when the parameter does not have a `:SESSION` key, it will reture a `HTTP.Request` rather than a `Session` object:

```julia
function start(req::HTTP.Request, res::HTTP.Response, params::Dict{Symbol,Any} = Dict{Symbol,Any}(); options::Dict{String,String} = Dict{String,String}()) :: Tuple{HTTP.Request,HTTP.Response,Dict{Symbol,Any}}

function session(params::Dict{Symbol,Any}) :: Sessions.Session
  ( (! haskey(params, Genie.PARAMS_SESSION_KEY) || params[Genie.PARAMS_SESSION_KEY] === nothing) ) &&
      (params[Genie.PARAMS_SESSION_KEY] = Sessions.start(params[Genie.PARAMS_REQUEST_KEY], params[Genie.PARAMS_RESPONSE_KEY])[1])

  params[Genie.PARAMS_SESSION_KEY]
end

```

@AquaIndigo

1. This test should explain it pretty well:  
[https://github.com/GenieFramework/Genie.jl/blob/master/test/tests\_Sessions.jl](https://github.com/GenieFramework/Genie.jl/blob/master/test/tests_Sessions.jl)

2. It looks like you’re setting up user authentication so I suggest trying the GenieAuthentication plugin: [https://github.com/GenieFramework/GenieAuthentication.jl](https://github.com/GenieFramework/GenieAuthentication.jl)

I’m so glad that I added `Sessions.init()` and the `Sessions.session` worked well.

However, the problem that I cannot get the session in the next request is still bothering me:

```julia
route("/ticket/all") do
  sess = Sessions.session(@params)
  println(sess)
  TicketsController.allTickets()
end

```

where

```julia
Genie.Sessions.Session("70c3a9c2bf659c250b8ad0e3cdba9acd81aa5be1a12be4701e389f957c3ad0d5", Dict{Symbol, Any}())

```

was displayed and I notice that it had a new name.

Thanks for the update @AquaIndigo - so basically a new session is generated with each request? Do you have the `sessions/` folder? Are sessions being created there (you should see files named as the session id).

Do you get any errors and warnings in the REPL?

What’s the output of `pkg> status`?

Yes, when I made a new request in the browser and a new file in the `session/` directory. And each `route` seems to generate one new session.

```julia
(DbTicket) pkg> st
Project DbTicket v0.1.0
Status `~/codes/JuliaProjects/dbTicket/Project.toml`
  [c43c736e] Genie v1.10.0
  [e6f89c97] LoggingExtras v0.4.2
  [739be429] MbedTLS v1.0.3
  [340e8cb6] SearchLight v0.21.1
  [1297d576] SearchLightMySQL v0.5.0
  [ade2ca70] Dates
  [56ddb016] Logging

```

And there were no warnings or errors.

@AquaIndigo as discussed on Genie’s Gitter, today’s v1.11 release should address the session problem in webkit based browsers. Please let me know how it works.

Thanks so much and the latest version works for me!
