koa连接redis做缓存

正确示范

const koa = require('koa');
const app = new koa();
const onError = require('koa-onerror');
const session = require('koa-generic-session');
const redisStore = require('koa-redis');
const config = require('./config');

const routing = require('./routers/index');
const THIRTY_MINTUES =12 * 60 * 60 * 1000;
// 处理错误
onError(app);


const redisConfig = {
    port: config.redis.PORT,
    host: config.redis.HOST,
    db: config.redis.DB,
    ttl: THIRTY_MINTUES               // 失效时间
};

// 配置session 中间件
app.keys = ['keys', 'keyskeys'];            // redis cookies 签名，必须要
app.use(session({
    store: redisStore(redisConfig)
}));


// 装在路由
routing(app);

module.exports = app;

使用示范

class TestController {
    static async setSession(ctx) {
        let session = ctx.session;
        // let session = this.session;
        let test = {
            name: 'yanle',
            age: 26
        };
        session.setSession = test;
        return ctx.body = {
            message: '成功'
        }
    }


    static async getSession(ctx) {
        let session = ctx.session;
        return ctx.body = session;
    }
}
module.export = TestController;

参数说明

After adding session middleware, you can use this.session to set or get the sessions.

Setting this.session = null; will destroy this session.

Altering this.session.cookie changes the cookie options of this user. Also you can use the cookie options in session the store. Use for example cookie.maxAge as the session store's ttl.

Calling this.regenerateSession will destroy any existing session and generate a new, empty one in its place. The new session will have a different ID.

Setting this.sessionSave = true will force saving the session regardless of any other options or conditions.

Setting this.sessionSave = false will prevent saving the session regardless of any other options or conditions.
