搜索框内输入需要
搜索的
内容，你将会看到网页
后台与
前台数据交互的变化，加载的数据以及数据请求的方式和参数。如图1.2：<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">
<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">

<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">
<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">多了一个search的请求
文件，我们点开和第一个对比发现，offset字段从0变成了10。我们复制一下这里的url在新开的
标签页粘贴后，发现如图1.5：<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">

<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">好了第一层我们差不多做好了，进入网站第二层，随意点击一个我们
搜索产生的
内容标题，
跳转至一个新的
页面，我们用同样的
方法，观察第二层我们与服务端交互的信息 如图 1.6：<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">
