說明：只是爬蟲的一個(gè)實(shí)現(xiàn)案例，所以沒有多做功能，只做了登錄跟課表功能，課表有修改周次，單擊課程顯示課程詳細(xì)信息等功能。

開發(fā)平臺：Android Studio

界面

使用TimetableView android課程表控件,需要添加依賴

jsoup依賴：compile 'org.jsoup:jsoup:1.10.2'

界面控件依賴： compile 'com.zhuangfei:TimetableView:2.0.6'

界面效果如下：

實(shí)現(xiàn)原理(爬蟲實(shí)現(xiàn))

使用jsoup爬取教務(wù)系統(tǒng)數(shù)據(jù)，connect()方法連接教務(wù)系統(tǒng)，直接利用cookie連接學(xué)生課表頁面，解析返回的HTML頁面獲取該用戶的全部課程并封裝為java對象,再存入數(shù)據(jù)庫，可以使用java后臺服務(wù)器傳json數(shù)據(jù)給android客戶端，android客戶端解析json數(shù)據(jù)，然后將課表數(shù)據(jù)展示出來。由于本案例小而單一，因此沒有配置服務(wù)器，改為將爬取的數(shù)據(jù)直接存入到android本地?cái)?shù)據(jù)庫SQLite，課表的展示去本地?cái)?shù)據(jù)庫查詢即可。

(注：各個(gè)學(xué)校學(xué)院的教務(wù)系統(tǒng)不盡相同，具體如何爬取數(shù)據(jù)詳見jsoup官方網(wǎng)站jsoup)
