壓力測試工具ab - Apache HTTP server benchmarking tool

不要亂摸發表於2018-05-15
ApacheHTTPServer

搞網際網路開發，壓力測試必不可少。壓力測試的工具很多，我用過ab和JMeter，今天主要講ab的用法。

1、ab是什麼

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、官網

2.1、文件地址

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

2.2、如何找到文件

 

2.3、下載安裝

3、用法

3.1、測試GET請求

3.3、帶Cookie

D:\Apache24\bin>ab -n 1000 -c 200 -C token=1234 -p D:\data.json -T application/json http://localhost:8080/coupon/save.json

data.json是這樣的：

{
    "merchantId": 10004,
    "couponName": "我媽最美",
    "couponType": 1,
    "parValue": 520,
    "quantity": 1000,
    "releaseStartTime": "2018-05-13 00:00:00",
    "releaseEndTime": "2018-05-13 23:59:59",
    "limitType": 1,
    "limitNum": 1,
    "remark": "媽媽，您辛苦了！"
}

4、Linux下使用ab

yum install httpd-tools

java -jar cjs-springboot-example.jar &

用法沒變

5、程式碼
