# Sessions for Rocket.rs
|
||
|
|
|
||
|
|
Adding cookie-based sessions to a rocket application is extremely simple:
|
||
|
|
|
||
|
|
```rust
|
||
|
|
#![feature(proc_macro_hygiene, decl_macro)]
|
||
|
|
#[macro_use] extern crate rocket;
|
||
|
|
|
||
|
|
use rocket_session::Session;
|
||
|
|
use std::time::Duration;
|
||
|
|
|
||
|
|
fn main() {
|
||
|
|
rocket::ignite()
|
||
|
|
.attach(Session::fairing(Duration::from_secs(3600)))
|
||
|
|
.mount("/", routes![index])
|
||
|
|
.launch();
|
||
|
|
}
|
||
|
|
|
||
|
|
#[get("/")]
|
||
|
|
fn index(session: Session) -> String {
|
||
|
|
let mut count: usize = session.get_or_default("count");
|
||
|
|
count += 1;
|
||
|
|
session.set("count", count);
|
||
|
|
|
||
|
|
format!("{} visits", count)
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Anything serializable can be stored in the session, just make sure to unpack it to the right type.
|
||
|
|
|
||
|
|
The session driver internally uses `serde_json::Value` and the `json_dotpath` crate.
|
||
|
|
Therefore, it's possible to use dotted paths and store the session data in a more structured way.
