##Server
A socket server which allows to communicate between websocket clients
and send commands between them.
The server can be incoken by
`socketserver = SockerServer()`
by default the server uses 127.0.0.1 (normaly equally to 'localhost') as the host and the port 8888.
This can be changed to any other host/port by using respective arguments:
`socketserver = SockerServer(port='localhost',port=8888)`
If the Server cannot bind to the host:port pair an OSError is thrown.
This can be used to connect to the first free port
```
SOCKETPORT=8888
notconnected = True
socketserver = None
while notconnected:
try:
socketserver = SockerServer(port=SOCKETPORT)
notconnected = False
except:
SOCKETPORT += 1
```
after the port is opened it can be run constantly by calling:
`socketserver.run_forever()`
By default the server ask any connected client for a identification and sends a time stamp which can be used for time synchronization (see below)
##Client
The package comes also with a client.
To invoke a client use:
`wsc = WebSocketClient("name",host="ws://127.0.0.1:8888")`
The name should be unique and the host has to be changed match the socket server.
If a host is provided (not None) the client connects immediately to the server. If no host is provides or the auto_connect is set to False
the connection has to be established by calling:
`wsc.connect_to_socket("hostadress")`
The client can call functions when connecting, disconnecting or an error occures:
to add a function call:
`wsc.add_on_open("name", func[,overwrite=False])#run func on connecting`
the name is used as a reference to remove the function if nescessary and overwrite=False (the default) protects already set functions from overwriting by the same name.
No parametes are passed to the function. Same goes for the disconnecting (add_on_close) and and error (add_on_error) functions.
By default the Client reconnects on error or on close. To turn this off set the **reconnect** attribute to false
In the same manner a on message can be assigned to the client. In this case the function passed resives the massage as parameter.
Initially an **intrinsic message validator** is added as on-message function which validates the massage according to the default message template:
```
{
"type": "messagetype",
"data": {},
"from": sendername,
"target": messagetarget,
}
```
By default if the messagetype is "cmd" the message is threaten as a commandmessage and validated.
A commandmessage has to have the data-structure:
```
{
"cmd": "commandname",
"args": [],
"kwargs": {}
}
```
Initially two commands are registered:
- "indentify": answers to the identtify request of the server and registers with the SocketClient.name
- "set_time": sets SocketClient.time to the given data which can be used for time synchronization.
additional commands can be registered via:
`wsc.add_cmd_function('name',func[,overwrite=False])`
Example:
```
import time
import logging
import random
import threading
from websocket_communication_server.messagetemplates import commandmessage
from websocket_communication_server.socketclient import WebSocketClient
from websocket_communication_server.socketserver import SockerServer, SOCKETPORT
class Testclass:
def __init__(self, host, name):
self.runime = 0
self.name = name
self.wsc = WebSocketClient(name, host=host)
self.wsc.add_cmd_function("pass_ball", self.pass_ball) # registers own pass_ball method to be called when reciving the pass_ball command
self.pingpong = "ping" if "1" in name else "pong"
self.opponent = "Player2" if "1" in name else "Player1"
def pass_ball(self, catch=None): #methods called by the message validator should have default attributes to be valid against "TypeError: pass_ball() missing 1 required positional argument: 'catch'"
if catch is None:
print("End of the game because the ball went missing somewhere")
return
print(self.pingpong) # prints ping or pong
if not catch:
print("Damn!") # dont like losing the ball
time.sleep(1) # delay in game because it would be way to fast without, maybe the flytime of the ball :)
self.wsc.write_to_socket(
commandmessage(
cmd="pass_ball", # the command to call at the reciver
sender=self.name, # sender of the command
target=self.opponent, # reciver
catch=random.random() < 0.8, # 80% ball catch
)
)
if __name__ == "__main__":
# connects to the firsts free port
notconnected = True
socketserver = None
while notconnected:
try:
socketserver = SockerServer(port=SOCKETPORT) # binds to 127.0.0.1:8888++
notconnected = False
except:
SOCKETPORT += 1
threading.Thread(
target=socketserver.run_forever
).start() # runs server forever in background
test1 = Testclass(host=socketserver.ws_adress, name="Player1") # create player 1
test2 = Testclass(host=socketserver.ws_adress, name="Player2") # create player 2
time.sleep(1) # gives the players enought timw to identify
test1.pass_ball(True) # throw the first ball
while 1:
time.sleep(1) # play forever
```
Output:
ping
pong
ping

ping

Damn!
