curl是利用URL语法在命令行方式下工作的开源文件传输工具
curl命令可以在开发web应用时，模拟前端发起的HTTP请求
1.下载curl
https://curl.haxx.se/download.html
我选择的，Windows 64 bit 7.65.3 binary the curl project，curl-7.65.3_1-win64-mingw.zip
2.解压
curl-7.65.3_1-win64-mingw
3.设置环境变量
set PATH=E:softwarecurl-7.65.3_1-win64-mingwin;%PATH%
4.配置IntelliJ IDEA
file——>settings——>Terminal
5.使用，打开

模拟formdata数据
E:softwarecurl-7.65.3_1-win64-mingwin>curl localhost:8080/api/getPost -X POST --data "id=1&name=abc"
{"id":1,"name":"abc","other":null,"string":" id=1 name=abc other=null"}
json数据
E:softwarecurl-7.65.3_1-win64-mingwin>curl localhost:8080/api/getPostJson -X POST -H "Content-Type:application/json" --data "{"id":"1","name":"abc","other":""}"
{"id":1,"name":"abc","other":"","string":" id=1 name=abc other="}
