之前張耀老師的網頁腳本由於51cto升級,課程列表頁面改用javascript失效了
筆者發現視頻課程頁面右邊的列表都爲靜態化後的視頻課程地址,遂將老師初始版本的腳本進行了修改,在對視頻課程頁面使用時結果正常,遂將及修改後的腳本和部分註釋發上來供大家研究
[root@m01 scripts]# cat html_to_table.sh #!/bin/bash # oldboy linux training # 2016-11-13 # 基於老男孩linux21期學員張耀開發腳本 # EduFile=/tmp/edu.html #process temp file1 EduFile2=/tmp/edu2.html #process 2 Url="$*" # Check for given parameters [ $# -eq 0 ] && { echo "USAGE: /bin/sh $0 http://...." exit 1 } # Judge url is ok? curl -I $Url &>/dev/null [ $? -ne 0 ] &&{ echo "Bad url,Please check it" exit 1 } # Defined get pagenum and CourseId Functions # Defined get pagenum and CourseId Functions #function getnum(){ # curl -s $Url>$EduFile # grep '"pagesGoEnd"' $EduFile &>/dev/null # if [ $? -eq 0 ] # then # num=`sed -rn 's#.*page=([0-9].*)" class="pagesGoEnd".*$#\1#gp' $EduFile` # else # num=`sed -rn 's|.*page=([0-9].*)#" class="pagesNum".*$|\1|gp' $EduFile` # fi # pagenum=${num:-1} # CourseId=`echo $Url|awk -F "[-.]" '{print $4}'` #} # Defined curl html Functions #function Curl(){ # getnum # for i in `seq $pagenum` # do # curl "http://edu.51cto.com/index.php?do=course&m=lessions&course_id=$CourseId&page=$i" 1>>$EduFile 2>/dev/null # done #} #分段沒了,原函數保留,視頻頁抓一遍就好 function Curl(){ curl "$*" 1>>$EduFile 2>/dev/null } # Defined Create table Functions function table(){ sum="" index=1 sed -rn '/lesson/ s#<.*(<a href=")(.*)#\1http://edu.51cto.com\2#gp' $EduFile > $EduFile2 while read line do sum=$sum"<tr><th width="40" scope="row">$index</th><td width="520">$line</td>" ((index++)) done <$EduFile2 } # Defined Create html Functions function html(){ cat >/tmp/oldboy.html<<-END <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>test</title> </head> <body> <table width="560" border="1"> $sum </table> </body> </html> END } function main(){ Curl table html } main
效果是相似的但是像換頁之類的功能都沒用到,還是有很多值得向前輩學習的地方
tips:cat語句特別是最後end不能有空格,前端縮進最好用tab鍵完成
