安全可靠的 UDP

該儲存庫提供安全可靠的資料流，其工作方式類似於 TCP。
我的目的是使用戶能夠在封閉 NAT 中的客戶端之間建立 P2P 連線。

特徵

純Python
像普通套接字物件一樣使用
類似於RUDP的協議
UDP打洞
高效能（10mb 時 4Mbps/s 向上和向下）
ipv4/ipv6
可選的非同步

要求

Python 3.6+
要求.txt

安裝

針對「無法在我的情況下工作」的用戶的教程

pip3 install --user srudp

測試

 git clone https://github.com/namuyan/srudp
cd srudp
pip3 install --user -r requirements.txt
python3 -m mypy --config-file=mypy.ini srudp
python3 -m unittest discover

示範

準備兩台獨立的PC。

 from srudp import SecureReliableSocket
from time import sleep , time
 
sock = SecureReliableSocket ()
sock . connect (( "<remote host 1>" , 12345 ))
 
while not sock . is_closed :
    sock . sendall ( b'hello ' + str ( time ()). encode ())
    sleep ( 3 )
print ( "closed" , sock )

一方，每 3 秒發送一次訊息「hello」。

 from srudp import SecureReliableSocket
from time import time
 
sock = SecureReliableSocket ()
sock . connect (( "<remote host 2>" , 12345 ))
 
while not sock . is_closed :
    data = sock . recv ( 1024 )
    if not data :
        break
    print ( time (), data )
print ( "closed" , sock )

另一邊，收到訊息，立即展示。

非同步用法

 from srudp import SecureReliableSocket
import asyncio

# Get a reference to the current event loop
loop = asyncio . get_event_loop ()

# create a socket
sock = SecureReliableSocket ()

# connect() on another thread because block event loop
address = ( "example.com" , 3000 )
await loop . run_in_executor ( None , sock . connect , ( address ,))

# Register the open socket to wait for data
reader , writer = await asyncio . open_connection ( sock = sock )

# read
data = await reader . read ( 1024 )

# write
writer . write ( b"hello" )
writer . write ( b"world" )
await writer . drain ()

# close
writer . close ()
