【Code Tools】AB性能测试工具（二）

一、测试Get请求

1.每次并发请求10个，总共1000个请求

ab -n  -c  https://www.baidu.com/

2.指定Header参数

通过-H来指定

ab -n  -c  -H 'Accept-Encoding: gzip' -H 'storeId: 12' https://www.baidu.com/?a=1&b=2

二、测试Post请求

ab -n  -c   -p "post.txt" -T "application/json" -H "Content-Type: application/json"  https://www.baidu.com/

-n：总请求次数（最小默认为 1）；

-c：并发次数（最小默认为 1 且不能大于总请求次数，例如：10 个请求，10 个并发，实际就是 1 人请求 1 次）；

-p：post 参数文档路径（-p 和 -T 参数要配合使用）；

-T：用于POST/PUT数据的内容类型头(即设置post.txt中的参数类型)

其他参数如下：
通过ab -help查看
