-c 并发数，模拟请求的用户数

-n 请求总数

-p 发送post请求的数据文件，文件中内容以key=value&key1=value1形式拼接参数

-T 设置content-type发送post请求时必须设置，application/x-www-form-urlencoded

更多参数参考以下：

$ ./abs.exe
D:\wamp\bin\apache\apache2.4.35\bin\abs.exe: wrong number of arguments
Usage: D:\wamp\bin\apache\apache2.4.35\bin\abs.exe [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
(SSL2, TLS1, TLS1.1, TLS1.2 or ALL)

测试示例

GET请求

./abs.exe -c 100 -n 1000 https://www.baidu.com/

POST请求

./abs.exe -c 100 -n 1000 -p “/home/post.txt” -T “application/x-www-form-urlencoded” https://www.baidu.com/

注意：如果只是一个域名后面没有任何参数，则需要在最后面加/，如请求接口地址是https://wwww.baidu.com，则发送请求时需要https://www.baidu.com/

测试结果

$ ./abs.exe -c 10 -n 100 https://www.baidu.com/

2.jmeter测试

自我介绍一下，小编13年上海交大毕业，曾经在小公司待过，也去过华为、OPPO等大厂，18年进入阿里一直到现在。

深知大多数软件测试工程师，想要提升技能，往往是自己摸索成长或者是报班学习，但对于培训机构动则几千的学费，着实压力不小。自己不成体系的自学效果低效又漫长，而且极易碰到天花板技术停滞不前！

因此收集整理了一份《2024年软件测试全套学习资料》，初衷也很简单，就是希望能够帮助到想自学提升又不知道该从何学起的朋友，同时减轻大家的负担。

既有适合小白学习的零基础资料，也有适合3年以上经验的小伙伴深入学习提升的进阶课程，基本涵盖了95%以上软件测试开发知识点，真正体系化！

由于文件比较大，这里只是将部分目录大纲截图出来，每个节点里面都包含大厂面经、学习笔记、源码讲义、实战项目、讲解视频，并且后续会持续更新
