======

HTTPie uses a simple JSON config file.
|
||||
HTTPie uses a simple ``config.json`` file. The file doesn’t exist by default
|
||||
but you can create it manually.
|
||||
|
||||
|
||||
|
||||
Config file location
|
||||
--------------------
|
||||
|
||||
Config file directory
|
||||
---------------------
|
||||
|
||||
The default location of the configuration file is ``~/.httpie/config.json``
|
||||
(or ``%APPDATA%\httpie\config.json`` on Windows). The config directory
|
||||
location can be changed by setting the ``HTTPIE_CONFIG_DIR``
|
||||
environment variable. To view the exact location run ``http --debug``.
|
||||
(or ``%APPDATA%\httpie\config.json`` on Windows).
|
||||
|
||||
The config directory can be changed by setting the ``$HTTPIE_CONFIG_DIR``
|
||||
environment variable:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ export HTTPIE_CONFIG_DIR=/tmp/httpie
|
||||
$ http example.org
|
||||
|
||||
To view the exact location run ``http --debug``.
|
||||
|
||||
|
||||
Configurable options
|
||||
--------------------
|
||||
|
||||
The JSON file contains an object with the following keys:
|
||||
Currently HTTPie offers a single configurable option:
|
||||
|
||||
|
||||
``default_options``
|
||||
~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
|
||||
An ``Array`` (by default empty) of default options that should be applied to
|
||||
every invocation of HTTPie.
|
||||
|
||||
For instance, you can use this option to change the default style and output
|
||||
options: ``"default_options": ["--style=fruity", "--body"]`` Another useful
|
||||
default option could be ``"--session=default"`` to make HTTPie always
|
||||
use `sessions`_ (one named ``default`` will automatically be used).
|
||||
Or you could change the implicit request content type from JSON to form by
|
||||
adding ``--form`` to the list.
|
||||
For instance, you can use this config option to change your default color theme:
|
||||
|
||||
|
||||
``__meta__``
|
||||
~~~~~~~~~~~~
|
||||
.. code-block:: bash
|
||||
|
||||
HTTPie automatically stores some of its metadata here. Please do not change.
|
||||
$ cat ~/.httpie/config.json
|
||||
|
||||
|
||||
.. code-block:: json
|
||||
|
||||
{
|
||||
"default_options": [
|
||||
"--style=fruity"
|
||||
]
|
||||
}
|
||||
|
||||
|
||||
Even though it is technically possible to include there any of HTTPie’s
|
||||
options, it is not recommended to modify the default behaviour in a way
|
||||
that would break your compatibility with the wider world as that can
|
||||
generate a lot of confusion.
