Nodejs操作redis

//npm install redis

//首先加载node_redis模块

var redis = require('redis');

// 创建redis连接

var client = redis.createClient('6379', '127.0.0.1');

client.on("error", function(err) {

console.log("Error " + err);

});

client.set('foo', 'bar', function() {

client.get('foo', function(error, fooValue) {

console.log(fooValue);

});

});

client.append('foo', 'CCC', function() {

client.get('foo', function(error, value) {

console.log(value);

});

});

// 通过key获取值

exports.get = function(key, callback) {

client.get(key, function(error, value) {

console.log(value);

callback(value);

});

}

// 设定key的值

exports.set = function(key, value) {

client.set(key, value, function() {

});

}

// key追加值

exports.append = function(key, value) {

client.append(key, value, function() {

});

}
