安全可靠的 UDP

该存储库提供安全可靠的数据流，其工作方式类似于 TCP。
我的目的是使用户能够在封闭 NAT 中的客户端之间创建 P2P 连接。

特征

纯Python
像普通套接字对象一样使用
类似于RUDP的协议
UDP打洞
高性能（10mb 时 4Mbps/s 向上和向下）
ipv4/ipv6
可选的异步

要求

Python 3.6+
要求.txt

安装

针对“无法在我的情况下工作”的用户的教程

pip3 install --user srudp

测试

 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

演示

准备两台独立的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 秒发送一次消息“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 )

另一边，收到消息，立即展示。

异步用法

 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 ()
