HTTPie: cURL for humans
=======================
**HTTPie is a CLI HTTP utility** built out of frustration with existing tools. The goal is to make CLI interaction with HTTP-based services as human-friendly as possible.
HTTPie does so by providing an ``http`` command that allows for issuing arbitrary HTTP requests using a **simple and natural syntax** and displaying **colorized responses**:

:alt: HTTPie compared to cURL
Under the hood, HTTPie uses the excellent `Requests <http://python-requests.org>`_ and `Pygments <http://pygments.org/>`_ Python libraries. Python 2.6+ is supported (including 3.x).
Installation
------------
The latest **stable version** of HTTPie can always be installed (or updated to) via `pip <http://www.pip-installer.org/en/latest/index.html>`_::
pip install -U httpie
Or, you can install the **development version** directly from GitHub:

:target: http://travis-ci.org/jkbr/httpie
:alt: Build Status of the master branch
::
pip install -U https://github.com/jkbr/httpie/tarball/master
There are packages available for `Ubuntu <http://packages.ubuntu.com/quantal/httpie>`_ and `Debian <http://packages.debian.org/wheezy/httpie>`_.
Usage
-----
Hello world::
http httpie.org
Synopsis::
http [flags] [METHOD] URL [items]
There are four types of key-value pair items available:
Headers (``Name:Value``)
Arbitrary HTTP headers. The ``:`` character is used to separate a header's name from its value, e.g., ``X-API-Token:123``.
Simple data fields (``field=value``)
Data items are included in the request body. Depending on the ``Content-Type``, they are automatically serialized as a JSON ``Object`` (default) or ``application/x-www-form-urlencoded`` (the ``-f`` flag). Data items use ``=`` as the separator, e.g., ``hello=world``.
Raw JSON fields (``field:=value``)
This item type is needed when ``Content-Type`` is JSON and a field's value is a ``Boolean``, ``Number``, nested ``Object`` or an ``Array``, because simple data items are always serialized as ``String``. E.g. ``pies:=[1,2,3]``.
File fields (``field@/path/to/file``)
Only available with ``-f`` / ``--form``. Use ``@`` as the separator, e.g., ``screenshot@/path/to/file.png``. The presence of a file field results into a ``multipart/form-data`` request.
Examples
^^^^^^^^
::
http PATCH api.example.com/person/1 X-API-Token:123 name=John email=john@example.org age:=29
The following request is issued::
PATCH /person/1 HTTP/1.1
User-Agent: HTTPie/0.1
X-API-Token: 123
Content-Type: application/json; charset=utf-8
{"name": "John", "email": "john@example.org", "age": 29}
It can easily be changed to a **form** request using the ``-f`` (or ``--form``) flag, which produces::
PATCH /person/1 HTTP/1.1
User-Agent: HTTPie/0.1
X-API-Token: 123
Content-Type: application/x-www-form-urlencoded; charset=utf-8
age=29&name=John&email=john%40example.org
It is also possible to send ``multipart/form-data`` requests, i.e., to simulate a **file upload form** submission. It is done using the ``--form`` / ``-f`` flag and passing one or more file fields::
http -f POST example.com/jobs name=John cv@~/Documents/cv.pdf
The above will send the same request as if the following HTML form were submitted::
<form enctype="multipart/form-data" method="post" action="http://example.com/jobs">
<input type="text" name="name" />
<input type="file" name="cv" />
</form>
A whole request body can be passed in via **``stdin``** instead, in which case it will be used with no further processing::
echo '{"name": "John"}' | http PATCH example.com/person/1 X-API-Token:123
# Or:
http POST example.com/person/1 X-API-Token:123 < person.json
That can be used for **piping services together**. The following example ``GET``s JSON data from the Github API and ``POST``s it to httpbin.org::
http -b GET https://api.github.com/repos/jkbr/httpie | http POST httpbin.org/post
The above can be further simplified by omitting ``GET`` and ``POST`` because they are both default here. The first command has no request data, whereas the second one does via ``stdin``::
http -b https://api.github.com/repos/jkbr/httpie | http httpbin.org/post
An alternative to ``stdin`` is to pass a file name whose content will be used as the request body. It has the advantage that the ``Content-Type`` header will automatically be set to the appropriate value based on the filename extension (using the ``mimetypes`` module). Therefore, the following will request will send the verbatim contents of the file with ``Content-Type: application/xml``::
http PUT httpbin.org/put @/data/file.xml
Flags
^^^^^
Most of the flags mirror the arguments understood by ``requests.request``. See ``http -h`` for more details::
usage: http [-h] [--version] [--json | --form] [--traceback]
[--pretty | --ugly]
[--print OUTPUT_OPTIONS | --verbose | --headers | --body]
[--style STYLE] [--auth AUTH] [--auth-type {basic,digest}]
[--verify VERIFY] [--proxy PROXY] [--allow-redirects]
[--timeout TIMEOUT]
[METHOD] URL [ITEM [ITEM ...]]
HTTPie - cURL for humans. <http://httpie.org>
positional arguments:
METHOD The HTTP method to be used for the request (GET, POST,
PUT, DELETE, PATCH, ...). If this argument is omitted,
then HTTPie will guess the HTTP method. If there is
some data to be sent, then it will be POST, otherwise
GET.
URL The protocol defaults to http:// if the URL does not
include one.
ITEM A key-value pair whose type is defined by the
separator used. It can be an HTTP header
(header:value), a data field to be used in the request
body (field_name=value), a raw JSON data field
(field_name:=value), or a file field
(field_name@/path/to/file). You can use a backslash to
escape a colliding separator in the field name.
optional arguments:
-h, --help show this help message and exit
--version show program's version number and exit
--json, -j (default) Data items are serialized as a JSON object.
The Content-Type and Accept headers are set to
application/json (if not set via the command line).
--form, -f Data items are serialized as form fields. The Content-
Type is set to application/x-www-form-urlencoded (if
not specifid). The presence of any file fields results
into a multipart/form-data request.
--traceback Print exception traceback should one occur.
--pretty If stdout is a terminal, the response is prettified by
default (colorized and indented if it is JSON). This
flag ensures prettifying even when stdout is
redirected.
--ugly, -u Do not prettify the response.
--print OUTPUT_OPTIONS, -p OUTPUT_OPTIONS
String specifying what should the output contain. "H"
stands for the request headers and "B" for the request
body. "h" stands for the response headers and "b" for
response the body. Defaults to "hb" which means that
the whole response (headers and body) is printed.
--verbose, -v Print the whole request as well as the response.
Shortcut for --print=HBhb.
--headers, -t Print only the response headers. Shortcut for
--print=h.
--body, -b Print only the response body. Shortcut for --print=b.
--style STYLE, -s STYLE
Output coloring style, one of autumn, borland, bw,
colorful, default, emacs, friendly, fruity, manni,
monokai, murphy, native, pastie, perldoc, rrt,
solarized, tango, trac, vim, vs. Defaults to
solarized. 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).
--auth AUTH, -a AUTH username:password
--auth-type {basic,digest}
The authentication mechanism to be used. Defaults to
"basic".
--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".
--proxy PROXY String mapping protocol to the URL of the proxy (e.g.
http:foo.bar:3128).
--allow-redirects Set this flag if full redirects are allowed (e.g. re-
POST-ing of data at new ``Location``)
--timeout TIMEOUT Float describes the timeout of the request (Use
socket.setdefaulttimeout() as fallback).
