pomelo下memcached的安装以及使用(二）

{
"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 memcached
app.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);});
