Chrome 插件获取指定域下的Cookie，代码示例

chrome_extension_get_cookie.js

// 获取单个cookie
chrome.cookies.get( { 
  url: 'http://iciba.com', 
  name: '_ustat' }, 
  function( cookie ){ 
    console.log( cookie ); 
  });
  
// 获取多个cookie，并设置到当前插件页面下
chrome.cookies.getAll( { domain: '.iciba.com'}, function( cookie ){ 
  cookie.forEach(function(c){ 
    console.log( c.name, c.value ); 
    document.cookie = (c.name + '=' + c.value + ';'); 
    }); 
  });
  
// 监控Cookie的变更
chrome.cookies.onChanged.addListener(function( changeInfo ){ console.log( changeInfo ); });
/* ->

Object {cause: "explicit", cookie: Object, removed: false}
