CURL://

CURL来源
The tool was about uploading and downloading data specified with a URL. It was a client-side program (the 'c'), a URL client, and would show the data (by default). So 'c' for Client and URL: cURL.
不带参数
不带有任何参数时，curl 就是发出 GET 请求。
curl https://www.qian.blue
-A参数指定客户端的用户代理标头，即User-Agent。curl 的默认用户代理字符串是curl/[version]。
$ curl -A 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.100 Safari/537.36' https://qian.blue
-b
-b参数用来向服务器发送 Cookie。
$ curl -b 'foo=bar' https://qian.blue
上面命令会生成一个标头Cookie: foo=bar，向服务器发送一个名为foo、值为bar的 Cookie。
$ curl -b 'foo1=bar;foo2=bar2' https://qian.blue
上面命令发送两个 Cookie。
$ curl -b cookies.txt https://www.qian.blue
