一、测试Get请求
1.每次并发请求10个，总共1000个请求
ab -n 1000 -c 10 /
2.指定Header参数
通过-H来指定
ab -n 1000 -c 10 -H 'Accept-Encoding: gzip' -H 'storeId: 12' /?a=1&b=2
二、测试Post请求
ab -n 1000 -c 10 -p "post.txt" -T "application/json" -H "Content-Type: application/json" /
-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
