</script> 用程序抓取国外某网站网页源代码,抓到的不是该网页的源码,在网页右键查看源代码时,发现多了以上语句,请问这是什么意思啊。如果能实现用程序抓取这种有点像被加密了的网页的源码呢?
<script>
document.write(unescape("%3Cscript src='" + (document.location.protocol == "https:" ? "https://sb" : "http://b") + ".scorecardresearch.com/beacon.js' %3E%3C/script%3E")); 这里是动态添加一个<script>标签来引用一个js文件
</script>
<script>
COMSCORE.beacon({ 这里是执行方法
c1:2,
