项目即将上线 老大说 小聂 咱的项目需要压测下  测试的工具有很多  小聂选择了最为简单ab 测试

   很多同学可能对ab 测试不了解 请点击 apache性能测试工具ab使用详解 详细了解

  由于是post api接口  我写了以下的sh脚本 

#!/usr/bin/env bash
echo "开始测试"
 ab -n4000 -c20  -p "login.json" -T "application/json" "http://localhost:8082/plugin/login"
 echo "测试结束"

  login.json是 要post 过去的参数

{
  "namespace":"liuyanban",
  "certificate":"5791b91bd63c82760c9f93ef",
  "logintype":0,
  "frame":"af",
  "openId": "c_1"
}

测试结果如下

./login.sh
开始测试
