第八天
话说小帅帅自从走进了淘宝开放平台这个迷雾森林，感觉这迷雾森林好大，正当他无所适从的时候。
一位悦耳动听的声音响起来了，甜甜的声音说道：亲，想通过这片森林吗，我将指引你前进。
小帅帅一听，那种感觉，身体不由自主的跟随这声音而去，突然一道强光闪过，啊.....
小帅帅惊醒了。小帅帅一看时间，我滴个天，这么晚了。就这样小帅帅从业一来第一次迟到。
其实小帅帅在平台里面琢磨了一个晚上，整个晚上其实也没琢磨个啥出来。
正当要到公司的时候，手机的铃声响起来了，一看是于老大的电话，接通电话。
于老大问候到：小帅帅，早啊， 你什么时候到公司丫。
小帅帅答到： 于老大，不好意思丫，昨天晚上研究那个淘宝开放平台，研究太玩了，今早睡过头了。不过我快到公司了....
于老大一听，不好意思责怪小帅帅啥，只好说道：辛苦你了，注意休息，学会劳逸结合...
小帅帅，回到： 好的，谢谢于老大的教诲，没事就挂了哈。。（ 0害怕于老大的糖衣炮弹0 ）
小帅帅回到公司后，于老大就给了一份整理后的Topclient给小帅帅，让他去研究下，看样子小帅帅还是乐于研究代码，让他看开放平台，还真看不出什么。
