ab -n 100 -c 100 测试目标url
AB指令介绍
-n requests 全部请求数 -c concurrency 并发数 -t timelimit 最传等待回应时间 -p postfile POST数据文件 -T content-type POST Content-type -v verbosity How much troubleshooting info to print -w Print out results in HTML tables -i Use HEAD instead of GET -x attributes String to insert as table attributes -y attributes String to insert as tr attributes -z attributes String to insert as td or th attributes -C attribute 加入cookie, eg. ‘Apache=1234. (repeatable) -H attribute 加入http头, eg. ‘Accept-Encoding: gzip‘ Inserted after all normal header lines. (repeatable) -A attribute http验证,分隔传递用户名及密码 -P attribute Add Basic Proxy Authentication, the attributes are a colon separated username and password.
