Introduction
HTTP Server for CircuitPython.
Supports
socketpool
orsocket
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:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle or individual libraries can be installed using circup.
Installing from PyPI
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:
pip3 install adafruit-circuitpython-httpserver
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-httpserver
To install in a virtual environment in your current project:
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:
pip3 install circup
With circup
installed and your CircuitPython device connected use the
following command to install:
circup install adafruit_httpserver
Or the following command to update an existing version:
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.
