Redis Cookie Store

a Redis store for tough-cookie module. See tough-cookie documentation for more info.

Installation

npm install --save @ijs/tough-cookie-redis-store

Options

• client An existing redis client object you normally get from redis.createClient()
• id optional ID for each redis store so that we can use multiple stores with the same redis database [ default: 'default']

Usage

const { createClient } = require('redis');
const { CookieJar } = require('tough-cookie');
const { RedisCookieStore } = require('@ijs/tough-cookie-redis-store');

const client = createClient();

const defaultJar = new CookieJar(new RedisCookieStore(client));

const myJar = new CookieJar(new RedisCookieStore(client, 'my-cookie-store'));

说明

内部使用redis hash结构存储

HSET的三个参数key, value, fieldValue分别是:
key: cookie-store:${store.id}:cookie:${cookie.domain}:${cookie.path}即域名+路径
value: cookie.key
fieldValue: JSON.stringify(cookie.toJSON())

node_redis 库有auto pipeline的能力所以代码使用SCAN进行循环执行HGETALL批量获取cookie
emm 具体性能测试没有详细进行，理论上是会因为大key（一个hash有很多成员）出现性能问题。

但是目前个人使用场景 new CookieJar(new RedisCookieStore(client, userId)) 是按照用户来区分， 理论上一个userId+域名+路径作为一个hash不会出现大key，就是redis中key总量比较大
