最近挂pt站，发现一段时间不登录，他就会封帐号。
所以考虑能不能写个脚本自动签到一下。
首先，chrome抓包url，在控制台右击，拷贝curl指令。

然后写个脚本自动跑一下这个curl指令。
再把这个指令丢进crontab，每天定时自动跑。

# cat sign.sh
#!/usr/bin
DATE=$(date +%Y%m%d%H%M%S)
echo $DATE >> sign.log

#签到

ret=$(echo $cm)
result=$(echo $ret | grep "您今天已经签到过了，请勿重复刷")
if [[ "$result" != "" ]];then
    echo "签到港知堂 成功">> sign.log
else
    echo "签到港知堂 失败">> sign.log
fi

#签到cmct
cm=$(curl 'https://hdcmct.org/usercp.php' -H 'Connection: keep-alive' -H 'Pragma: no-cache' -H 'Cache-Control: no-cache' -H 'Upgrade-Insecure-Requests: 1' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8' -H 'Accept-Encoding: gzip, deflate, br' -H 'Accept-Language: zh-CN,zh;q=0.9,en;q=0.8' -H 'Cookie:xxxx' --compressed)
ret=$(echo $cm)
result=$(echo $ret | grep "加入日期")
if [[ "$result" != "" ]];then
    echo "签到cmct 成功">> sign.log
else
    echo "签到cmct 失败">> sign.log
fi

#签到hdcity

result=$(echo $ret | grep "已签到")
if [[ "$result" != "" ]];then
    echo "签到hdcity 成功" >> sign.log
else
    echo "签到hdcity 失败">> sign.log
fi

cookie失效了，就自己重新生成一下curl命令。

关于crontab

#查看状态
service crond status 
service crond start
service crond stop
service crond restart
service crond reload

ps -ef|grep cron

查看列表
crontab -l
文件目录 /var/spool/cron/
