以前にhttpie でリクエストヘッダも表示する というメモを書きました。 改めて、HTTPie のインストール方法 / 基本的な使い方をメモしておきます。
インストール
Debian / Ubuntu にインストールする
標準リポジトリから apt-get でインストール可能です。
apt-get -y install httpieRHEL / CentOS にインストールする
標準リポジトリにはパッケージが無い為、EPEL からインストールします。
yum -y install epel-release
yum -y install python2-httpiepip でインストールする
pip でインストールするのも簡単です。 以下は pip 自体からインストールする場合の手順です。
yum -y install gcc python-devel
curl -L https://bootstrap.pypa.io/get-pip.py | python
pip install httpie現時点ではバージョン 0.9.9 がインストールされました。
# http --version
0.9.9使い方
基本的な使い方は以下の通りです。
オプションを指定せずに実行する
HTTPie の実体は（httpie では無くて）http です。 http に続けて URL を指定します。
# http google.com
HTTP/1.1 302 Found
Cache-Control: private
Content-Length: 271
Content-Type: text/html; charset=UTF-8
Date: Tue, 05 Dec 2017 16:27:03 GMT
Location: http://www.google.co.jp/?gfe_rd=cr&dcr=0&ei=18gmWs-sF7LK8gfAsaOgDQ
Referrer-Policy: no-referrer
<HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8">
<TITLE>302 Moved</TITLE></HEAD><BODY>
<H1>302 Moved</H1>
The document has moved
<A HREF="http://www.google.co.jp/?gfe_rd=cr&dcr=0&ei=18gmWs-sF7LK8gfAsaOgDQ">here</A>.
</BODY></HTML>特定部分を表示する
特定部分を表示させるには --print= に続けて、以下のように指定します。
| 出力させたい部分 | オプション | 実行例 |
|---|---|---|
| リクエスト・ヘッダ | H |
http --print=H POST httpie.org key1=value1 key2=value2 |
| リクエスト・ボディ | B |
http --print=B POST httpie.org key1=value1 key2=value2 |
| レスポンス・ヘッダ | h |
http --print=h POST httpie.org key1=value1 key2=value2 |
| レスポンス・ボディ | b |
http --print=b POST httpie.org key1=value1 key2=value2 |
オプションは複数同時に指定することも可能です。 例えば、リクエスト・ヘッダとリクエスト・ボディを表示するのであれば --print=HB を指定します。
Cookie を保存する
Cookie を保存したい場合は --sessoin オプションを指定します。 絶対パスを指定 しなかった 場合は ~/.httpie 配下に Cookie が保存されます。
# http --print=h --session=./cookie.txt http://www.whatarecookies.com/cookietest.asp参考

[METHOD] URL [REQUEST_ITEM [REQUEST_ITEM ...]]
HTTPie - a CLI, cURL-like tool for humans. <http://httpie.org>
Positional Arguments:
These arguments come after any flags and in the order they are listed here.
Only URL is required.
METHOD
The HTTP method to be used for the request (GET, POST, PUT, DELETE, ...).
This argument can be omitted in which case HTTPie will use POST if there
is some data to be sent, otherwise GET:
$ http example.org # => GET
$ http example.org hello=world # => POST
URL
The scheme defaults to 'http://' if the URL does not include one.
(You can override this with: --default-scheme=https)
You can also use a shorthand for localhost
$ http :3000 # => http://localhost:3000
$ http :/foo # => http://localhost/foo
REQUEST_ITEM
Optional key-value pairs to be included in the request. The separator used
determines the type:
':' HTTP headers:
Referer:http://httpie.org Cookie:foo=bar User-Agent:bacon/1.0
'==' URL parameters to be appended to the request URI:
search==httpie
'=' Data fields to be serialized into a JSON object (with --json, -j)
or form data (with --form, -f):
name=HTTPie language=Python description='CLI HTTP client'
':=' Non-string JSON data fields (only with --json, -j):
awesome:=true amount:=42 colors:='["red", "green", "blue"]'
'@' Form file fields (only with --form, -f):
cs@~/Documents/CV.pdf
'=@' A data field like '=', but takes a file path and embeds its content:
essay=@Documents/essay.txt
':=@' A raw JSON field like ':=', but takes a file path and embeds its content:
package:=@./package.json
You can use a backslash to escape a colliding separator in the field name:
field-name-with\:colon=value
Predefined Content Types:
--json, -j
(default) Data items from the command line are serialized as a JSON object.
The Content-Type and Accept headers are set to application/json
(if not specified).
--form, -f
Data items from the command line are serialized as form fields.
The Content-Type is set to application/x-www-form-urlencoded (if not
specified). The presence of any file fields results in a
multipart/form-data request.
Output Processing:
--pretty {all,colors,format,none}
Controls output processing. The value can be "none" to not prettify
the output (default for redirected output), "all" to apply both colors
and formatting (default for terminal output), "colors", or "format".
--style STYLE, -s STYLE
Output coloring style (default is "solarized"). One of:
abap, algol, algol_nu, arduino, autumn, borland, bw,
colorful, default, emacs, friendly, fruity, igor, lovelace,
manni, monokai, murphy, native, paraiso-dark, paraiso-light,
pastie, perldoc, rainbow_dash, rrt, solarized, tango, trac,
vim, vs, xcode
For this option to work properly, please make sure that the $TERM
environment variable is set to "xterm-256color" or similar
(e.g., via `export TERM=xterm-256color' in your ~/.bashrc).
Output Options:
--print WHAT, -p WHAT
String specifying what the output should contain:
'H' request headers
'B' request body
'h' response headers
'b' response body
The default behaviour is 'hb' (i.e., the response headers and body
is printed), if standard output is not redirected. If the output is piped
to another program or to a file, then only the response body is printed
by default.
--headers, -h
Print only the response headers. Shortcut for --print=h.
--body, -b
Print only the response body. Shortcut for --print=b.
--verbose, -v
Verbose output. Print the whole request as well as the response. Also print
any intermediary requests/responses (such as redirects).
It's a shortcut for: --all --print=HBbh
--all
By default, only the final request/response is shown. Use this flag to show
any intermediary requests/responses as well. Intermediary requests include
followed redirects (with --follow), the first unauthorized request when
Digest auth is used (--auth=digest), etc.
--history-print WHAT, -P WHAT
The same as --print, -p but applies only to intermediary requests/responses
(such as redirects) when their inclusion is enabled with --all. If this
options is not specified, then they are formatted the same way as the final
response.
--stream, -S
Always stream the output by line, i.e., behave like `tail -f'.
Without --stream and with --pretty (either set or implied),
HTTPie fetches the whole response before it outputs the processed data.
Set this option when you want to continuously display a prettified
long-lived response, such as one from the Twitter streaming API.
It is useful also without --pretty: It ensures that the output is flushed
more often and in smaller chunks.
--output FILE, -o FILE
Save output to FILE instead of stdout. If --download is also set, then only
the response body is saved to FILE. Other parts of the HTTP exchange are
printed to stderr.
--download, -d
Do not print the response body to stdout. Rather, download it and store it
in a file. The filename is guessed unless specified with --output
[filename]. This action is similar to the default behaviour of wget.
--continue, -c
Resume an interrupted download. Note that the --output option needs to be
specified as well.
Sessions:
--session SESSION_NAME_OR_PATH
Create, or reuse and update a session. Within a session, custom headers,
auth credential, as well as any cookies sent by the server persist between
requests.
Session files are stored in:
/root/.httpie/sessions/<HOST>/<SESSION_NAME>.json.
--session-read-only SESSION_NAME_OR_PATH
Create or read a session without updating it form the request/response
exchange.
Authentication:
--auth USER[:PASS], -a USER[:PASS]
If only the username is provided (-a username), HTTPie will prompt
for the password.
--auth-type {basic,digest}, -A {basic,digest}
The authentication mechanism to be used. Defaults to "basic".
"basic": Basic HTTP auth
"digest": Digest HTTP auth
Network:
--proxy PROTOCOL:PROXY_URL
String mapping protocol to the URL of the proxy
(e.g. http:http://foo.bar:3128). You can specify multiple proxies with
different protocols.
--follow, -F
Follow 30x Location redirects.
--max-redirects MAX_REDIRECTS
By default, requests have a limit of 30 redirects (works with --follow).
--timeout SECONDS
The connection timeout of the request in seconds. The default value is
30 seconds.
--check-status
By default, HTTPie exits with 0 when no network or other fatal errors
occur. This flag instructs HTTPie to also check the HTTP status code and
exit with an error if the status indicates one.
When the server replies with a 4xx (Client Error) or 5xx (Server Error)
status code, HTTPie exits with 4 or 5 respectively. If the response is a
3xx (Redirect) and --follow hasn't been set, then the exit status is 3.
Also an error message is written to stderr if stdout is redirected.
SSL:
--verify VERIFY
Set to "no" to skip checking the host's SSL certificate. You can also pass
the path to a CA_BUNDLE file for private certs. You can also set the
REQUESTS_CA_BUNDLE environment variable. Defaults to "yes".
--ssl {ssl2.3,ssl3,tls1,tls1.1,tls1.2}
The desired protocol version to use. This will default to
SSL v2.3 which will negotiate the highest protocol that both
the server and your installation of OpenSSL support. Available protocols
may vary depending on OpenSSL installation (only the supported ones
are shown here).
--cert CERT
You can specify a local cert to use as client side SSL certificate.
This file may either contain both private key and certificate or you may
specify --cert-key separately.
--cert-key CERT_KEY
The private key to use with SSL. Only needed if --cert is given and the
certificate file does not contain the private key.
Troubleshooting:
--ignore-stdin, -I
Do not attempt to read stdin.
--help
Show this help message and exit.
--version
Show version and exit.
--traceback
Prints the exception traceback should one occur.
--default-scheme DEFAULT_SCHEME
The default scheme to use if not specified in the URL.
--debug
Prints the exception traceback should one occur, as well as other
information useful for debugging HTTPie itself and for reporting bugs.
For every --OPTION there is also a --no-OPTION that reverts OPTION
to its default value.
