示例代码：
<script type="text/javascript">
!function(){
var e=/([http|https]:\/\/[a-zA-Z0-9\_\.]+\.baidu\.com)/gi,
r=window.location.href,
o=document.referrer;
// console.log(e);
// console.log(r);
// console.log(o);
if(!e.test(r)){ // 为了防止 这个网址是百度自家的产品
// console.log(‘a‘);
var n="//api.share.baidu.com/s.gif";
o?(n+="?r="+encodeURIComponent(document.referrer),r&&(n+="&l="+r)):r&&(n+="?l="+r);
var t=new Image;
t.src=n;
console.log(t);
};
// if(!e.test(‘http://www.baidu.com/‘)){
// console.log(‘a‘);
// }else{
// console.log(‘b‘);
// };
}(window);
</script>
