curl，用于发送请求的命令行工具，一个 HTTP 请求客户端（实际上它也可以做 FTP/SCP/TELNET 协议的事情，可类比于浏览器中的 fetch。

curl 是最为流行的 HTTP 请求命令行工具，在谷歌浏览器控制台的网络面板中，可将当前请求转化为 curl。

在学习及调试 HTTP 的过程中，可结合 curl 与 Apifo Echo 一同使用。

Apifox Echo 是 Apifox 出品的一款 HTTP 简单的接口请求和返回数据服务，可以模拟各种接口请求参数和返回数据的情况，供开发人员和测试人员学习测试 API 使用。

curl

直接发送 GET 请求：

$ curl ifconfig.me
118.73.227.215

curl --request

--request/-X，指定请求方法，如 POST 等。

$ curl \
  -X POST \
  -H "Accept: application/vnd.github+json" \ 
  -H "Authorization: token <TOKEN>" \
  https://api.github.com/repos/OWNER/REPO/issues \
  -d '{"title":"Found a bug","body":"I'\''m having a problem with this.","assignees":["octocat"],"milestone":1,"labels":["bug"]}'
$ curl https://echo.apifox.com/post -X POST -H "a: 3" -H "b: 4"
{
  "args": {}, 
  "data": "", 
  "files": {}, 
  "form": {}, 
  "headers": {
    "A": "3", 
    "Accept": "*/*", 
    "B": "4", 
    "Connection": "close", 
    "Host": "echo.apifox.com", 
    "User-Agent": "curl/7.79.1"
  }, 
  "json": null, 
  "origin": "118.113.0.137", 
  "url": "https://echo.apifox.com/post"
}

curl --head

--head/-I 发送 HEAD 请求，只需要返回 Response Header。

$ curl --head https://shanyue.tech

curl --location

--location/-L，追踪重定向。

# 重定向两次后请求到数据
$ curl --location http://zhihu.com
# 可使用 --head，查看到三次响应
$ curl --head --location http://zhihu.com

httpie && examples

httpie 是现代化更为流行的一个 HTTP 客户端，支持色彩、JSON 等。

# 发送 JSON 数据给服务器端，httpie 比 curl 方便很多，不需要自己手写 header，curl 默认为 application/x-www-form-urlencoded
$ http POST https://echo.apifox.com/post "a: 3" name=shanyue
$ curl -X POST https://echo.apifox.com/post -H "a: 3" -H "content-type: application/json" -d '{"name": "shanyue"}'
# 发送 Form 数据给服务器端，curl/httpie 都比较方便
$ http POST https://echo.apifox.com/post "a: 3" name=shanyue
$ curl -X POST https://echo.apifox.com/post -H "a: 3" -d name=shanyue
# 上传文件
$ http POST https://echo.apifox.com/post &lt; Readme.md
$ curl -X POST https://echo.apifox.com/post -H "content-type: application/json" -d @Readme.md
# multipart 上传文件
$ http --multipart https://echo.apifox.com/post a=3 b@'Readme.md'

在 Apifox Echo 中，还可以将请求直接转化为命令行。
