pg-ntex-session 0.1.0

Overview

By default, only cookie session backend is implemented. This crate provides PostgreSQL back end with Diesel's engine

In general, you insert a session middleware and initialize it, such as a PgNtexSession. To access session data, Session extractor must be used. Session extractor allows us to get or set session data.

Example

use ntex::web::{self, App, HttpResponse, Error};
use pg_ntex_session::{encryption::Simple, PgNtexSession};
use diesel::{r2d2::{ConnectionManager, Pool}, PgConnection};
use std::sync::Arc;

fn index(session: Session) -> Result<&'static str, Error> {
    // access session data
    if let Some(count) = session.get::<i32>("counter")? {
        println!("SESSION value: {}", count);
        session.set("counter", count+1)?;
    } else {
        session.set("counter", 1)?;
    }
!
    Ok("Welcome!")
}

//DB connection sting
const DATABASE_URL:&'static str="postgres://postgres:password@localhost/my_db";
//32 characters
const ENC_KEY:&'static str="29dba93e4ce64609bb5d592dab92ec00";
//Pool of connection manager
const :Arc<Pool<ConnectionManager<PgConnection>>>=Arc::new(

       .build(ConnectionManager::<PgConnection>::new(DATABASE_URL))
       .unwrap()
