# Higher level Datagram support for Asyncio
|
||||
Simple wrappers that allow you to `await read()` from datagrams as suggested
|
||||
by Guido van Rossum
|
||||
[here](https://github.com/python/asyncio/pull/321#issuecomment-187022351). I
|
||||
frequently found myself having to inherit from `asyncio.DatagramProtocol` and
|
||||
implement this over and over.
|
||||
|
||||
# Design
|
||||
The goal of this package is to make implementing common patterns that use datagrams
|
||||
simple and straight-forward while still supporting more esoteric options. This is done
|
||||
by taking an opinionated stance on the API that differs from parts of asyncio. For instance,
|
||||
rather than exposing a function like
|
||||
[create\_datagram\_endpoint](https://docs.python.org/3/library/asyncio-eventloop.html#asyncio.loop.create_datagram_endpoint)
|
||||
which supports many use-cases and has conflicting parameters, `asyncio_dgram`
|
||||
only provides three functions for creating a stream:
|
||||
|
||||
- `connect((host, port))`: Creates a datagram endpoint which can only
|
||||
communicate with the endpoint it connected to.
|
||||
- `bind((host, port))`: Creates a datagram endpoint that can communicate
|
||||
with anyone, but must specified the destination address every time it
|
||||
sends.
|
||||
- `from_socket(sock)`: If the above two functions are not sufficient, then
|
||||
`asyncio_dgram` simply lets the caller setup the socket as they see fit.
|
||||
|
||||
|
||||
# Example UDP echo client and server
|
||||
Following the example of asyncio documentation, here's what a UDP echo client
|
||||
and server would look like.
|
||||
```python
|
||||
import asyncio
|
||||
|
||||
import asyncio_dgram
|
||||
|
||||
|
||||
async def udp_echo_client():
|
||||
stream = await asyncio_dgram.connect(("127.0.0.1", 8888))
|
||||
|
||||
await stream.send(b"Hello World!")
|
||||
data, remote_addr = await stream.recv()
|
||||
print(f"Client received: {data.decode()!r}")
|
||||
|
||||
stream.close()
|
||||
|
||||
|
||||
async def udp_echo_server():
|
||||
stream = await asyncio_dgram.bind(("127.0.0.1", 8888))
|
||||
|
||||
print(f"Serving on {stream.sockname}")
|
||||
|
||||
data, remote_addr = await stream.recv()
|
||||
print(f"Echoing {data.decode()!r}")
|
||||
await stream.send(data, remote_addr)
|
||||
|
||||
await asyncio.sleep(0.5)
|
||||
print(f"Shutting down server")
|
||||
|
||||
|
||||
def main():
|
||||
loop = asyncio.get_event_loop()
|
||||
loop.run_until_complete(asyncio.gather(udp_echo_server(), udp_echo_client()))
|
||||
|
||||
|
||||
if __name__ == "__main__":
|
||||
main()
|
||||
```
