序言

在 Linux 操作系统上对后端程序进行测试的时候，需要进行模拟连接或者书写测试脚本时，就需要用到这个实用的curl 命令了。

模拟GET请求

访问百度，通过GET方法请求

命令格式： curl protocol://address:port/url

curl http://www.baidu.com
curl www.baidu.com

模拟POST请求

1、参数直接在header里面

获取天气数据，通过POST方法请求

命令格式：curl -d "args"  "protocol://address:port/url"

curl -d "city=dongguan&appkey=8010132dcf54491a4eaa387f4db61774" "https://way.jd.com/he/freeweather"
curl -d "city=dongguan&appkey=8010132dcf54491a4eaa387f4db61774" "https://way.jd.com/he/freeweather"

这种方法是参数直接在header里面的

2、json数据直接在body里面，可以通过重定向将输出指定到特定文件

如果将输出指定到文件可以通过重定向进行操作

命令格式：curl -H "Content-Type:application/json" -X POST --data (json.data) URL

curl -H "Content-Type:application/json" -X POST --data '{"message": "sunshine"}' http://localhost:8000/

这种方法是json数据直接在body里面的
