var app = angular.module("myApp",['ngCookies']);

app.controller('namesCtrl', ['$cookies','$cookieStore',function($cookies, $cookieStore){}]);

$cookies.put(key, value[, options]);

$cookieStore.put(key, value);

//使用$cookies设置cookie
$cookies.put('userName', 'yangmin');

//使用$cookieStore设置cookie
$cookieStore.put('userName','yangmin');

$cookies.get(key);

$cookieStore.get(key);

$cookies.get(userName);//yangmin

$cookieStore.get("userName"); //yangmin

$cookies.remove(key[, options]);

$cookieStore.remove(key);

$cookies.remove("userName");

$cookieStore.remove("userName");

$cookies.put("person",{name:"Amy",age:23});
var person = $cookies.get("person");
console.log(person.age);//undefined

$cookieStore.put("person",{name:"Amy",age:23});
var person = $cookieStore.get("person");
console.log(person.age);//23

var expireDate = new Date();
expireDate.setDate(expireDate.getDate() + 1);
$cookies.put("userName",“yangmin”,{'expires': expireDate});//“userName”一天后过期
