手把手教你做关键词匹配项目(搜索引擎)---- 第八天
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。

Topclient来自Taobao SDK ,只是稍微修正,去掉了一些框架的依赖,源码为:

小帅帅拿着一看,又是天书,悲剧了。。 继续研究吧。。
就这样小帅帅又躲深山去修炼九阴真经了。
