我的 express 应用程序使用 PassportJS 来存储身份验证会话,但它在 redis 存储中创建了数量可笑的密钥,并且所有密钥看起来都一样:
"{\"cookie\":{\"originalMaxAge\":null,\"expires\":null,\"httpOnly\":true,\"path\":\"/\"},\"passport\":{}}"
他们确实有 TTL,但商店的规模正在无缘无故地增长。知道为什么要创建这些吗?我的钥匙看起来像:
"sess:8R3A-k6dARJvxXFdAXr5nTG7MeC7JTxb"
"sess:s4VYC-k-nmfSf7n-qGQJimFmt30EYNDp"
"sess:BS7WO92Nyl5R0wAbJ-Vo9o8w1apu0kp7"
"sess:0B1AKS6-MCclPvOXV0nlvNio8U8fxyQO"
"sess:v0UWf60LMwKmMVZgo4RWumX313yPsiD0"
如果我只是观察一下,大约每秒或两秒钟就会创建大约 10 个键。
这是我的会话代码的样子:
var express = require('express'),
....
session = require('express-session'),
redisStore = require('connect-redis')(session);
...
app.use(express.static(path.resolve('./public')));
//Redis
var redisClient = redisHelper.init();
app.use(session({
secret: '...',
store: new redisStore({
client: redisClient,
ttl: 86400
}),
resave: false,
saveUninitialized: false,
cookie:{maxAge:86400}
}));
//Passport
app.use(passport.initialize());
app.use(passport.session());
...
Redis init 函数返回一个 redis 客户端的实例:
exports.init = function () {
redisClient = redis.createClient(config.redis.port, config.redis.server, {});
redisClient.auth(config.redis.auth);
redisClient.on('error', function (error) {
//TODO: log the error
winston.error('Error while talking to Redis', {message: error});
});
return redisClient;
};
