Messaging

The PV080 server (https://pv080.fi.muni.cz/) provides a functionality to exchange messages between students. The type of the content of the message is bytes. To send a message to a particular UČO use the function send_message and to receive a message use the recv_message function.

Each message comes from a sender UČO and is sent to another UČO (the sender and the receiver can be the same person). For every pair of UČO only the last message is recorded.

pv080_crypto.messaging.send_message(uco_from: int, uco_to: int, content: bytes) → str[source]

Sends the content to https://pv080.fi.muni.cz/msg server, where it is readable by anyone on the internet.

Parameters:

  • uco_from – Is the UČO of the sender.

  • uco_to – Is the UČO of the receiver.

  • content – Is the message encoded in bytes.

Returns:

The status message of the result of this API call to the server.

Example:

>>> send_message(uco_from=408788, uco_to=408788, content=b"message")
'overwritten'
pv080_crypto.messaging.recv_message(uco: int) → Mapping[str, int | bytes][source]

Receive the messages that have been sent to uco.

Parameters:

uco – Is the UČO of the addressee/receiver.

Returns:

A dictionary where the keys are UČOs of the senders and values are their messages.

Example:

>>> send_message(uco_from=408788, uco_to=408788, content=b"message")
'overwritten'
>>> messages = recv_message(uco=408788)
>>> message_from_408788 = messages[408788]
>>> assert message_from_408788 == b"message"
