茶还是咖啡
ab是一种用于测试Apache超文本传输协议(HTTP)服务器的工具。apache自带ab工具,可以测试
apache、IIs、tomcat、nginx等服务器
linux 安装
yum -y install httpd-tools
ab手册
Usage: ab [options] [http[s]://]hostname[:port]/path
Options are:
-n requests Number of requests to perform
-c concurrency Number of multiple requests to make at a time
-t timelimit Seconds to max. to spend on benchmarking
This implies -n 50000
-s timeout Seconds to max. wait for each response
Default is 30 seconds
-b windowsize Size of TCP send/receive buffer, in bytes
-B address Address to bind to when making outgoing connections
-p postfile File containing data to POST. Remember also to set -T
-u putfile File containing data to PUT. Remember also to set -T
-T content-type Content-type header to use for POST/PUT data, eg.
'application/x-www-form-urlencoded'
Default is 'text/plain'
-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 Add cookie, eg. 'Apache=1234'. (repeatable)
-H attribute Add Arbitrary header line, eg. 'Accept-Encoding: gzip'
Inserted after all normal header lines. (repeatable)
-A attribute Add Basic WWW Authentication, the attributes
are a colon separated username and password.
-P attribute Add Basic Proxy Authentication, the attributes
are a colon separated username and password.
-X proxy:port Proxyserver and port number to use
-V Print version number and exit
-k Use HTTP KeepAlive feature
-d Do not show percentiles served table.
-S Do not show confidence estimators and warnings.
-q Do not show progress when doing more than 150 requests
-l Accept variable document length (use this for dynamic pages)
-g filename Output collected data to gnuplot format file.
-e filename Output CSV file with percentages served
-r Don't exit on socket receive errors.
-m method Method name
-h Display usage information (this message)
-I Disable TLS Server Name Indication (SNI) extension
-Z ciphersuite Specify SSL/TLS cipher suite (See openssl ciphers)
-f protocol Specify SSL/TLS protocol
(TLS1, TLS1.1, TLS1.2 or ALL)
-E certfile Specify optional client certificate chain and private key
直接看操作手册可能有点上头,我给大家翻译了一些

通过结果可以看出压测的一些信息,比如最小链接时间,最长链接时间,请求响应的信息等。
发送POST请求
请求地址:https://www.test.com/user/secret/listPage
并发数:100
请求总数:1000
content-type:application/json
请求体:{}
POST请求需要将请求体放到指定的文件中,新建一个post.txt文件,文件内容是请求体。
ab -c 100 -n 1000 -p post.txt -T 'application/json' https://www.test.com/user/secret/listPage
