( -w <format> --write-out <format> )
http_codeのみ確認したいときなどに活用できます。%{variable_name} の形式で指定します。
レスポンスボディは非表示にしたいので -o /dev/null を指定しています。
$ curl -w 'http_code: %{http_code}\n' http://localhost:8000/ -sS -o /dev/null

(省略)以下のように指定することもできます。
$ curl -v -X POST http://localhost:8000/ \
-d 'aaa=111&bbb=222&ccc=333'URLエンコード
+ application/x-www-form-urlencoded
( --data-urlencode <data> )
まずは、-dオプション でURLエンコードされていないケースを確認します。
$ curl -X POST http://localhost:8000/ \
> --trace-ascii /dev/stdout \
> --data 'aaa=1 1' \
> --data 'bbb=2%2' \
> --data 'ccc=3&3'
(省略)
0000: aaa=1 1&bbb=2%2&ccc=3&3
(省略)次に、--data-urlencodeオプション でURLエンコードされているケースを確認します。
$ curl -X POST http://localhost:8000/ \
> --trace-ascii /dev/stdout \
> --data-urlencode 'aaa=1 1' \
> --data-urlencode 'bbb=2%2' \
> --data-urlencode 'ccc=3&3'
(省略)
0000: aaa=1%201&bbb=2%252&ccc=3%263
(省略)multipart/form-data
( -F <name=content>
--form <name=content> )
ファイルアップロードします。
-Fオプション を利用すると Content-Type が multipart/form-data になります。
$ cat sample.txt
ABCDEFG
$
$
$ curl -v -X POST http://localhost:8000/ \
> --trace-ascii /dev/stdout \
> -F 'file=@sample.txt' \
> -F 'aaa=111' \
> -F 'bbb=222'
Warning: --trace-ascii overrides an earlier trace/verbose option

(省略)リクエストヘッダー指定
( -H <header/@file> --header <header/@file> )
-Hオプション でリクエストヘッダーを指定できます。
$ curl -v http://localhost:8000 \
> -H 'Content-Type: application/json' \
> -H 'Referer: http://example.com' \

(省略)Cookie
受信
( -c <filename> )
サーバー側でCookieを設定するように調整しました。

{"message":"Unauthorized"}--basic -u <user:password> でBasic認証を通すことができます。
$ curl -i http://localhost:8000 \
> --basic -u yamada:sample_password
HTTP/1.1 200 OK
Content-Type: text/plain; charset=UTF-8
