appfog 怎么用node连接自带的redis - CNode技术社区

文档没看懂

{"redis-2.2":[
 {
 "name":"redis-example",
 "label":"redis-2.2",
 "plan":"free",
 "tags":["redis","redis-2.2","key-value","nosql"],
 "credentials":{
 "hostname":"10.7.66.164",
 "host":"10.7.66.164",
 "port":5004,
 "password":"191dc43f-69a3-4d31-ac5e-4b66155b2e8e",
 "name":"9e3f3a9c-82ba-4c2e-bc83-b498e5447251"
 }
 }
]}

是不是要这样写

var options = {
 host: '10.7.66.164',
 hostname:'10.7.66.164',
 port: 5004,
 prefix: 'chs-sess',
 pass:这里怎么写?
 还有有这里貌似没有写name的选项
}
 app.use(express.cookieParser());
 app.use(express.session({ store: new RedisStore(options), secret: 'zclcat' }))

还有prefix有什么用

https://docs.appfog.com/add-ons/rediscloud#rediscloud-node

var redis = require('redis');
var url = require('url');
var redisURL = url.parse(process.env.REDISCLOUD_URL);
var client = redis.createClient(redisURL.port, redisURL.hostname, {no_ready_check: true});
client.auth(redisURL.auth.split(":")[1]);

谢谢,不过这个是在add-ons里,我选的是在service,貌似也没有输入用户名密码的,直接能用

https://docs.appfog.com/services/redis

process.env.VCAP_SERVICES

这个取到的就是 那个 json对象 var env = JSON.parse(process.env.VCAP_SERVICES); var db = env[‘redis-2.2’][0][‘credentials’]; store: new RedisStore(db); 这样就ok了,要学会看文档!

错了 var db = env[‘redis-2.2’][‘credentials’]; 没有那个[0]我是在我mysql上改的改错了

@javanode 非常感谢,我去试试
