ab性能测试

AB(ApacheBench) 是 Apache 自带的超文本传输协议 (HTTP) 性能测试工具。 其设计意图是描绘当前所安装的 Apache 的执行性能， 主要是显示 Apache 每秒可以处理多少个请求。

1.http请求

ab -n30000 -c1000 "http://10.1.1.21:8080/"

2.ab 测试 http 接口 (POST)

ab -n400 -c20 -p "img.json" -T "application/x-www-form-urlencoded" "http://10.1.1.21:8080/test.do"

3.img.json 为符合接口格式的字符串

MIME 类型 application/x-www-form-urlencoded 与 multipart/form-data 和 text/plain 参考

类似于 curl,curl 指定 post 请 @ 指定文件

curl "http://10.1.1.21:8080/test.do" -d @/root/img.json

4.ab 测试 webservice 接口

ab -k -T "Content-Type:text/xml;charset=UTF-8" -p data.xml -n 1000 -c 32 http://10.1.1.21:8080/services/routeService?wsdl

注意：data.xml 必须符合 wsdl 规范，可以使用 soapUI 生成

如果报错：no soapaction header

ab -k -T "Content-Type:text/xml;charset=UTF-8;soapaction=''" -p data.xml -n 1000 -c 32 http://10.1.1.21:8080/services/routeService?wsdl
