Note: The domain name and URL in the following example are changed according to the actual situation during the test
Curl loop test (take 66 cycles as an example, use null.jpg instead of url. When testing, you can change it to the url you want to test, the port 80 and port 43 of the domain name tested here, you can also test other ports)
ipv6
for ((i=0;i<66;i++));do hc=`curl -o /dev/null -s -w %{http_code} http:/ / write the domain name here / null.jpg -x [ Write ipv6 address here] :80`;echo $i,$hc;done
for ((i=0;i<200;i++));do hc=`curl -6 -k -g -o /dev/null -s -w %{http_code} "https:// [write ipv6 here address] : 443 / this is written at the domain /null.jpg"`;echo $ i, $ hc; done
ipv4
for ((i=0;i<66;i++));do hc=`curl -o /dev/null -s -w %{http_code} http:// write domain name here /lnull.jpg -x this Write IP address : 80`;echo $i,$hc;done
for ((i=0;i<66;i++));do hc=`curl -k -o /dev/null -s -w %{http_code} "https://1此处写IP地址:443/wx3.sinaimg.cn/null.jpg"`;echo $i,$hc;done
curl test to get download time
curl -vo /dev/null "http://www.abc.com" -x 1.1.1.1:80
curl -vo /dev/null "http://www.abc.com/null.jpg" -x 1.1.1.1:80
curl to view the response time of the machine
curl -vo /dev/null "http://www.abv.com" -x 127.0.0.1:80
curl test whether the domain name supports http2.0 (tested on centos8 devices)
curl --http2 -I /dev/null "https://www.abc.com/null.jpg" --resolve www.abc.com:443:1.1.1.1
Test whether to ignore the cache
curl -svo /dev/null http://$name/null.jpg -x www.abc.com:80
curl -svo /dev/null http://$name/null.jpg?a=1 -x www.abc.com:80
Compare the two commands to observe whether the x-cache value has changed
The x-cache value remains unchanged: the domain name allows the cache to be ignored
x-cache value changed: domain name is not allowed to ignore cache
Cross-domain testing
curl -svo /dev/null http://$name/null.jpg -H "Origin:www.baidu.com" -x www.abc.com :80
refer anti-hotlink test
curl -svo 1 'http://www.abc.com/null.jpg ' -x 1.1.1.1:80 -H "referer:http://www..baidu.com/u/2287091337"
