压力测试工具ab - Apache HTTP server benchmarking tool

2022-06-15 17:57:56

搞互联网开发，压力测试必不可少。压力测试的工具很多，我用过ab和JMeter，今天主要讲ab的用法。

1、ab是什么

ab is a tool for benchmarking your Apache Hypertext Transfer Protocol (HTTP) server. It is designed to give you an impression of how your current Apache installation performs. This especially shows you how many requests per second your Apache installation is capable of serving.

2、官网

2.1、文档地址

http://httpd.apache.org/docs/2.4/programs/ab.html

2.2、如何找到文档

2.3、下载安装

3、用法

3.1、测试GET请求

3.3、带Cookie

D:\Apache24\bin>ab -n  -c  -C token= -p D:\data.json -T application/json http://localhost:8080/coupon/save.json

data.json是这样的：

{

    "merchantId": ,

    "couponName": "我妈最美",

    "couponType": ,

    "parValue": ,

    "quantity": ,

    "releaseStartTime": "2018-05-13 00:00:00",

    "releaseEndTime": "2018-05-13 23:59:59",

    "limitType": ,

    "limitNum": ,

    "remark": "妈妈，您辛苦了！"

}

4、Linux下使用ab

yum install httpd-tools

java -jar cjs-springboot-example.jar &

用法没变
