HTTP Server for CircuitPython.

• Supports socketpool or socket as a source of sockets; can be used in CPython.
• HTTP 1.1.
• Serves files from a designated root.
• Routing for serving computed responses from handlers.
• Gives access to request headers, query parameters, form data, body and client's address (the one from which the request came).
• Supports chunked transfer encoding.
• Supports URL parameters and wildcard URLs.
• Supports HTTP Basic and Bearer Authentication on both server and route per level.
• Supports Websockets and Server-Sent Events.

Dependencies

This driver depends on:

• Adafruit CircuitPython <https://github.com/adafruit/circuitpython>_

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle <https://circuitpython.org/libraries> or individual libraries can be installed using circup <https://github.com/adafruit/circup>.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI <https://pypi.org/project/adafruit-circuitpython-httpserver/>_. To install for current user:

.. code-block:: shell

pip3 install adafruit-circuitpython-httpserver

To install system-wide (this may be required in some cases):

.. code-block:: shell

sudo pip3 install adafruit-circuitpython-httpserver

To install in a virtual environment in your current project:

.. code-block:: shell

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-httpserver

Installing to a Connected CircuitPython Device with Circup

Make sure that you have circup installed in your Python environment. Install it with the following command if necessary:

.. code-block:: shell

pip3 install circup

With circup installed and your CircuitPython device connected use the following command to install:

.. code-block:: shell

circup install adafruit_httpserver

Or the following command to update an existing version:

.. code-block:: shell

circup update

Security

The HTTP server implementation in this package is not robust and should only be deployed on trusted networks. For instance, there are trivial denial of service attacks against adafruit_httpserver. Pull requests that improve the server's security and robustness are of course welcome.
