使用shell测试cdn状态

  公司使用多家cdn,测试cdn在各个地方的响应情况,以便于提高视频访问的用户体验。分别在阿里云华南1,华东1,华东2,华北2等不同地区节点测试。该随笔为自己所用。

 

1.该脚本会测试某一cdn的url,如果302,继续测试,如果是503,则测试cdn源站是否也为503,并记http_code,录测试时间以及测试的url等信息。

#!/bin/bash

#set -e
start_time=$(date +%s)
today=$(date +%F)
mkdir -pv /cdn/logs &> /dev/null
dl200="/cdn/logs/dl200-$today.log"
dlno200="/cdn/logs/dlno200-$today.log"
> $dl200
> $dlno200
#echo $dl200 $dlno200
#exit
cat /cdn/shell/dltxt/dl-$today |while read line
do
#echo $line
HTTP_CODE=$(curl -XGET -I -m -o /dev/null -s -w "%{http_code}""\n" $line)
if [ "$HTTP_CODE" -eq ];then
CURRENT_TIME=$(date '+%Y%m%d %H:%M:%S')
echo $HTTP_CODE $CURRENT_TIME $line >> $dl200
elif [ "$HTTP_CODE" -eq ];then
HTTP_NEW_CODE=
NEW_URL=$(curl -XGET -I -m -s $line |grep ^Location|awk -F" " '{print $2}'|tr -d '\r'|tr -d '$')
while [ "$HTTP_NEW_CODE" -eq ]
do
#echo $NEW_URL
HTTP_NEW_CODE=$(curl -XGET -I -m -o /dev/null -s -w "%{http_code}""\n" $NEW_URL)
#echo $HTTP_NEW_CODE
#if [ "$HTTP_NEW_CODE" -eq 200 ];then
# echo $HTTP_NEW_CODE $NEW_RUL >> /xiaoke/shell/logs/gs200.log
if [ "$HTTP_NEW_CODE" -eq ];then
NEW_URL=$(curl -XGET -I -m -s $NEW_URL |grep ^Location|awk -F" " '{print $2}'|tr -d '\r'|tr -d '$')
elif [ "$HTTP_NEW_CODE" -eq ];then
CURRENT_TIME=$(date '+%Y%m%d %H:%M:%S')
echo $HTTP_NEW_CODE $CURRENT_TIME $NEW_URL >> $dl200
elif [ "$HTTP_NEW_CODE" -eq ];then
CURRENT_TIME=$(date '+%Y%m%d %H:%M:%S')
echo $HTTP_NEW_CODE $CURRENT_TIME $NEW_URL >> $dlno200
SOURCE_URL=$(echo $line |sed 's;gxbvideo-dl;gxbvideo;g')
SOURCE_CODE=$(curl -XGET -I -m -o /dev/null -s -w "%{http_code}""\n" $SOURCE_URL)
if [ "$SOURCE_CODE" -eq ];then
echo $SOURCE_CODE $CURRENT_TIME $SOURCE_URL >> $dlno200
else
echo $SOURCE_CODE $CURRENT_TIME $SOURCE_URL >> $dlno200
fi
else
CURRENT_TIME=$(date '+%Y%m%d %H:%M:%S')
echo $HTTP_NEW_CODE $CURRENT_TIME $NEW_URL >> $dlno200
fi
done
elif [ "$HTTP_CODE" -eq ];then
CURRENT_TIME=$(date '+%Y%m%d %H:%M:%S')
echo $HTTP_CODE $CURRENT_TIME $line >> $dlno200
SOURCE_URL=$(echo $line |sed 's;gxbvideo-dl;gxbvideo;g')
SOURCE_CODE=$(curl -XGET -I -m -o /dev/null -s -w "%{http_code}""\n" $SOURCE_URL)
if [ "$SOURCE_CODE" -eq ];then
echo $SOURCE_CODE $CURRENT_TIME $SOURCE_URL >> $dlno200
else
echo $SOURCE_CODE $CURRENT_TIME $SOURCE_URL >> $dlno200
fi
else
#current_time=$(date '+%Y%m%d %H:%M:%S')
CURRENT_TIME=$(date '+%Y%m%d %H:%M:%S')
echo $HTTP_CODE $CURRENT_TIME $line >> $dlno200
fi
sleep
done
end_time=$(date +%s)
#echo $end_time
delta_time=`expr $end_time - $start_time`
echo "总耗时:$delta_time秒" >> $dl200

2.查看测试信息日志即可。
