pomelo下memcached的安装以及使用(二）

上一篇已经正常安装了memcached和开启了memcached服务，接下来在pomelo中使用memcached

{  "development": [    "127.0.0.1:11211"  ],  "production": [    "127.0.0.1:11211"  ]}

然后在app中创建一个memcached.js

/** * Created by Mic on 16/1/11. */var cachedClient = module.exports;var _mem;cachedClient.init = function (app) {    if (!!_mem) {        return cachedClient;    } else {        var M = require('memcached');        console.log(app.get('memcached'));        _mem = new M(app.get("memcached"), {compressionThreshold: 10});        return cachedClient;    }};cachedClient.set = function (key, args, cb) {    console.log('memcached set ',key,args,cb);    _mem.set(key, args, 0, function (err, result) {        if (err) {            console.error(err);        }        if (!!cb && typeof cb === 'function') {            cb(err, result);        }    });};cachedClient.get = function (key, cb) {    console.log('memcached get ',key,cb);    _mem.get(key, function (err, result) {        console.log('#get ',err,result);        if (err) {            console.error(err);        }        if (!!cb && typeof cb === 'function') {            cb(err, result);        }    });};cachedClient.del = function (key, cb) {    _mem.del(key, function (err, result) {        if (err) {            console.error(err);        }        if (!!cb && typeof cb === 'function') {            cb(err, result);        }    });};

最后在app.js中添加配置

//add for memcachedapp.configure('production|development',function(){   app.loadConfig('memcached',app.getBase()+'/config/memcached.json');   var memclient = require('./app/dao/memcached/memcached').init(app);   app.set('memclient',memclient);});
使用
//testvar pomelo = require('pomelo');var mem = pomelo.app.get('memclient');
mem.set('userName',uid);mem.get('userName',function(err,data){   console.log('MEMCACHED ',data);});
