# Python SSDP
Python asyncio library for Simple Service Discovery Protocol (SSDP).
SSDP is a UPnP substandard. For more information see:
https://en.wikipedia.org/wiki/Simple_Service_Discovery_Protocol
## Setup
```bash
python3 -m pip install ssdp # lightweight, without any dependencies
# or
python3 -m pip install ssdp[cli] # with cli support for testing and debugging
```
## Usage
### CLI
```console-interactive
$ ssdp --help
Usage: ssdp [OPTIONS] COMMAND [ARGS]...
SSDP command line interface.
Options:
-v, --verbose Increase verbosity.
--help Show this message and exit.
Commands:
discover Send out an M-SEARCH request and listening for responses.
```
#### Discover
Discover devices on the network and print the responses.
```console
ssdp discover --help
Usage: ssdp discover [OPTIONS]
Send out an M-SEARCH request and listening for responses.
Options:
-b, --bind TEXT Specify alternate bind address [default: all
interfaces]
--search-target, --st TEXT Search target [default: ssdp:all]
--max-wait, --mx INTEGER Maximum wait time in seconds [default: 5]
--help Show this message and exit.
```
Example:
```console
$ ssdp discover
[::]:1900 - - [Sun Jun 11 12:07:09 2023] M-SEARCH * HTTP/1.1
HOST: 239.255.255.250:1900
MAN: "ssdp:discover"
MX: 5
ST: ssdp:all
[::ffff:192.168.178.1]:1900 - - [Sun Jun 11 12:07:09 2023] HTTP/1.1 200 OK
Cache-Control: max-age=1800
Location: http://192.168.178.1:49000/MediaServerDevDesc.xml
Server: FRITZ!Box 7590 UPnP/1.0 AVM FRITZ!Box 7590 154.07.50
Ext:

USN: uuid:fa095ecc-e13e-40e7-8e6c-3ca62f98471f::upnp:rootdevice
```
### Python API
#### Messages
The SSDP library provides two classes for SSDP messages: `SSDPRequest` and
`SSDPResponse`. Both classes are subclasses of `SSDPMessage` and provide
the following methods:
- `parse`: Parse a SSDP message from a string.
- `__bytes__`: Convert the SSDP message to a bytes object.
- `__str__`: Convert the SSDP message to a string.
You can parse a SSDP message from a string with the `parse` method.
It will return a `SSDPRequest` or `SSDPResponse` object depending
on the message type.
```pycon
>>> import ssdp.messages
>>> ssdp.messages.SSDPRequest.parse('NOTIFY * HTTP/1.1\r\n\r\n')
<ssdp.messages.SSDPRequest object at 0x7f8b1c0b6a90>
>>> ssdp.messages.SSDPResponse.parse('HTTP/1.1 200 OK\r\n\r\n')
<ssdp.messages.SSDPResponse object at 0x7f8b1c0b6a90>
```
##### SSDPRequest
```pycon
>>> from ssdp.messages import SSDPRequest
>>> SSDPRequest('NOTIFY', headers={
... 'HOST': '10.0.0.42',
... 'NT': 'upnp:rootdevice',
... 'NTS': 'ssdp:alive',
... })
<ssdp.messages.SSDPRequest object at 0x7f8b1c0b6a90>
```
The `SSDPRequest` class provides the a `sendto` method to send the request
over a open transport.
```pycon
>>> from ssdp import network, messages
>>> notify = messages.SSDPRequest('NOTIFY')
>>> notify.sendto(transport, (network.MULTICAST_ADDRESS_IPV4, network.PORT))
```
##### SSDPResponse
```pycon
>>> from ssdp.messages import SSDPResponse
>>> SSDPResponse(200, 'OK', headers={
... 'CACHE-CONTROL': 'max-age=1800',
... 'LOCATION': 'http://10.0.0.1:80/description.xml',
... 'SERVER': 'Linux/2.6.18 UPnP/1.0 quick_ssdp/1.0',
... 'ST': 'upnp:rootdevice',
... })
<ssdp.messages.SSDPResponse object at 0x7f8b1c0b6a90>
```
#### Asyncio SSD Protocol datagram endpoint
The `aio.SimpleServiceDiscoveryProtocol` class is a subclass of
`asyncio.DatagramProtocol` and provides the following additional methods:
- `response_received`: Called when a SSDP response was received.
- `request_received`: Called when a SSDP request was received.
The protocol can be used to react to SSDP messages in an asyncio event loop.
This example sends a SSDP NOTIFY message and prints all received SSDP messages:
```python
#!/usr/bin/env python3
import asyncio
import socket
from ssdp import aio, messages, network
class MyProtocol(aio.SimpleServiceDiscoveryProtocol):
def response_received(self, response, addr):
print(response, addr)
def request_received(self, request, addr):
print(request, addr)
loop = asyncio.get_event_loop()
connect = loop.create_datagram_endpoint(MyProtocol, family=socket.AF_INET)
transport, protocol = loop.run_until_complete(connect)
notify = messages.SSDPRequest('NOTIFY')
notify.sendto(transport, (network.MULTICAST_ADDRESS_IPV4, network.PORT))
try:
loop.run_forever()
except KeyboardInterrupt:
pass
transport.close()
loop.close()
```
## SSDP lexer plugin for [Pygments][pygments]
The SSDP library comes with a lexer plugin for [Pygments][pygments]
to highlight SSDP messages. It's based on a HTTP lexer and adds SSDP
specific keywords.
You can install the plugin with the following command:
```bash
pip install ssdp[pymgments] # included in ssdp[cli]
```
You can either get the lexer by name:
```pycon
>>> from pygments.lexers import get_lexer_by_name
>>> get_lexer_by_name('ssdp')
<pygments.lexers.SSDPLexer>
```
Highlighting a SSDP message, could look like this:
```python
#/usr/bin/env python3
from pygments import highlight
from pygments.lexers import get_lexer_by_name
from pygments.formatters import TerminalFormatter
if __name__ == '__main__':
lexer = get_lexer_by_name('ssdp')
formatter = TerminalFormatter()
code = 'NOTIFY * HTTP/1.1\r\nHOST: localhost:1900'
msg = highlight(code, lexer, formatter)
print(msg)
```
