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

    -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

                    (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

参数信息 变量 说明
-n request 请求总数
-c concurrency 并发数
-t timelimit 用于基准测试的最长时间
-s timeout 请求超时时间,默认30s
-b windowsize TCP发送/接收缓冲区的大小,以字节为单位
-B address 请求地址
-p postfile post请求体(是一个文件)
-u putfile put请求体(是一个文件)
-T contentType post/put请求的content-type。eg:'application/json';'applicationx-www-form-urlencoded'
-v verbosity 设置显示信息的详细程度 - 4或更大值会显示头信息, 3或更大值可以显示响应代码(404, 200等), 2或更大值可以显示警告和其他信息。 -V 显示版本号并退出。
-w 在HTML表格中打印结果
-i 执行HEAD请求,而不是GET请求
-x attributes 要作为表属性插入的字符串
-y attributes 作为tr属性插入的字符串
-z attributes 作为td属性插入的字符串
-C attributes 添加cookie eg. 'Apache=1234'
-H attributes 添加Header eg.'Accept-Encoding: gzip'
-k 使用HTTP KeepAlive功能
-g filename 将收集到的数据输出到gnuplot格式文件。
-e filename 结果输出到CSV文件
-r 发生socker错误时不退出
-h 不展示用例信息

压测GET请求

请求地址:http://127.0.0.1:8074/raindrop/snowflake
并发数 100

ab -c 100 -n 1000 http://127.0.0.1:8074/raindrop/snowflake

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
