参数说明
官方文档参考这里。
ab -c 100 -n 10000 -k -r https://www.baidu.com/
- -c：concurrency，每次发送的请求次数，默认一次一个。如：-c 100 表示每次发送100个请求，模拟100人同时访问。
- -n：requests，本次测试的总请求数。
- 上面命令的含义：每次发送100个请求，共发送10000个请求。
示例1：压力测试
shell> ab -c 100 -n 10000 -k -r https://www.baidu.com/

示例2：测试post接口
ab -c 100 -n 1000 -r -k -p postdata_001_001.txt -T 'application/json' https://xxx.xxx.xxx/api
- postdata_001_001.txt 为post数据文件。post数据文件中的内容与接口所需参数保持一致。
post数据文件该如何编写？
可能是这样
uid=1&data={"username": "admin", "msg":"并发测试","type": "txt", "file": "","time":"2021-12-22
也可能是这样
{
"address":"124",
"amount":125
}
如果不能确定是什么样，可以先用接口测试工具测通，从接口测试工具中将post数据导出并保存成post数据文件。以apifox为例：
apr_pollset_poll: The timeout specified has expired (70007)
加个-k参数
apr_socket_recv: Connection reset by peer (104)
加个-r参数
