curl 基础

curl

json placeholder site, could be used to test rest API

另一个restapi测试网站，似乎这个网站更好

也可以用
github的开发者站点

curl website:

curl http://google.com
curl -L http://google.com

-L: incase redirect

其他：

curl -o outputFile url
curl -i https://reqres.in/api/users/2
curl https://reqres.in/api/users/2

-i: 加上header info

curl --head <url>: 仅获取头文件信息
curl -I <url>： 同上 （大写的i）
curl -v verbose: 通讯详细信息
curl --trace <tracelogfile> URL: trace 并把信息输入log file
curl --trace-ascii <tracelogfile> URL: 更详细的信息

curl -H "header detail info title" <weburl>

curl下载图片
找到online 图片的URL

curl -O <pic URL>

可利用jsonplaceholder做一些测试：

curl -X PUT -d "title=hello" https://jsonplaceholder.typicode.com/

DEL可用： -X DELETE

FTP server 上传文件

curl -u <username@xxx.com:passwd> -T <filename> <ftpserverurl>

POST 方法中
curl -d or curl --data 可以把data post 上
例如

\xh$ curl https://reqres.in/api/users -d "user=morhpeus&job=leader"
{"user":"morhpeus","job":"leader","id":"329","createdAt":"2020-06-15T12:47:45.097Z"}%   

再例如使用-X POST 参数：

\xh$ curl -X POST -H "Accept:application/json" https://reqres.in/api/users -d '{"name":"morpheus","job":"leader"}'
{"{\"name\":\"morpheus\",\"job\":\"leader\"}":"","id":"119","createdAt":"2020-06-15T12:50:31.948Z"}%          

-X PUT 例子：

\xh$ curl -X POST -H "Accept:application/json" https://reqres.in/api/users -d '{"name":"morpheus","job":"leader"}'
{"{\"name\":\"morpheus\",\"job\":\"leader\"}":"","id":"119","createdAt":"2020-06-15T12:50:31.948Z"}%                                \xh$ curl -i X PUT https://reqres.in/api/users/2 -d '{"name":"morpheus","job":"leader"}'
