我根据python中关于套接字的指南编写了两个程序。
我使用的是rasbperirypi3作为客户机，一台普通的linux ubuntu计算机作为服务器。这是服务器软件：import socket
import sys
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = ('localhost', 15000)
print("starting up on %s port %s" % server_address, file=sys.stderr)
sock.bind(server_address)
# Listen for incoming connections
sock.listen(1)
while True:
# Wait for a connection
print("waiting for a connection", file=sys.stderr)
connection, client_address = sock.accept()
try:
print("connection from ", client_address, file=sys.stderr)
# Receive the data in small chunks and retransmit it
while True:
data = connection.recv(16)
print("received %s" % data, file=sys.stderr)
if data:
print("sending data back to the client", file=sys.stderr)
connection.sendall(data)
else:
print("no more data from ", client_address, file=sys.stderr)
break
finally:
# Clean up the connection
connection.close()
这是客户端软件：
^{pr2}$
这是服务器上的输出：peter@GIGAS:~/thermServer$ python3 thermServer.py
starting up on localhost port 15000
waiting for a connection
这是树莓派的输出：pi@raspberrypi:~ $ python3 thermClient.py
connecting to 192.168.18.250 port 15000
Traceback (most recent call last):
File "thermClient.py", line 10, in
sock.connect(server_address)
ConnectionRefusedError: [Errno 111] Connection refused
我已经转发了路由器中的端口，但由于这是内部通信，这应该无关紧要，我是错过了在服务器中添加一些可以正常打开端口的东西，还是需要在linux机器上处理项目之外的东西？在
