如何修复 LAN 文件传输的 windows 拒绝错误
How to fix windows decline error for lan file transfer
我是一名 14 岁的软件设计初学者，但对 python 网络的基础和敏锐知识有很好的了解。我最近得到了一个 raspberry pi 3 b+ 全新的，我正在尝试制作一个 python 程序，允许我将我的 hp PC 输入的信息传输到我的 pi，以便它可以显示信息，这个项目是为了帮助我完成学业，我输入了代码并且它是 运行s 但是当我尝试 运行 "client code" 时，这样我的 pi 就可以接收输入数据，我得到一个错误说设备拒绝了我的连接请求，我应该怎么做才能解决这个问题？如果你想看代码，我可以 post，但我不确定是否有必要。
我只尝试更改两个程序中的端口号，因为这不是问题所在，而且我是 LAN 和网络方面的新手，我没有尝试过其他任何东西。
根据要求，我的代码是：（不是 HTML、CSS 或 HTML。使用该界面更容易。
# send.py
import socket # Import socket module
port = 60000 # Reserve a port for your service.
s = socket.socket() # Create a socket object
host = socket.gethostname() # Get local machine name
s.bind((host, port)) # Bind to the port
s.listen(5) # Now wait for client connection.
print 'Server listening....'
while True:
conn, addr = s.accept() # Establish connection with client.
print 'Got connection from', addr
data = conn.recv(1024)
print('Server received', repr(data))
filename='mytext.txt'
f = open(filename,'rb')
l = f.read(1024)
while (l):
conn.send(l)
print('Sent ',repr(l))
l = f.read(1024)
f.close()
print('Done sending')
conn.send('Thank you for connecting')
conn.close()
# recieve.py
import socket # Import socket module

host = socket.gethostname() # Get local machine name
port = 60000 # Reserve a port for your service.
s.connect((host, port))
s.send("Hello server!")
with open('received_file', 'wb') as f:
print 'file opened'
while True:
print('receiving data...')
data = s.recv(1024)
print('data=%s', (data))
if not data:
break
# write data to a file
f.write(data)
f.close()
print('Successfully get the file')
s.close()
print('connection closed')
很遗憾，这个答案需要 Python 3.5+。
在 运行 此代码之前，请确保您已经计算出您将用于服务器和客户端的 IP（帮助在底部）。
第 1 步 - 确保简单的 ping 工作正常
服务器代码：
import socket
# FIND IP
# The IP to use will be different depending
# on whether you have WiFi or Ethernet, so
# you need to choose whichever one that is
ips = socket.gethostbyname_ex(socket.gethostname())[-1]
print(*[f"{i}: {j}" for i, j in enumerate(ips)], sep="\n")
ip = ips[int(input(" > "))]
# SELECT PORT
port = 10000
#SETUP SERVER
# Create server socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind((ip, port))
# A queue of 1 clients is more than enough for our application
sock.listen(1)
print(f"Listening on {ip}:{port}")
while True:
try:
(clientsock, address) = sock.accept()
# so if there's nothing to read we don't wait too long
clientsock.settimeout(0.01)
ping_string = clientsock.recv(5).decode()
if ping_string == "ping!":
print("ping!")
clientsock.sendall(b"ping!")
else:
print("no ping!")
print(ping_string)
clientsock.sendall(b"nopng")
clientsock.shutdown(1)
clientsock.close()
except KeyboardInterrupt:
# Add a way to safely exit the infinite loop
break
sock.close()
客户代码：
import socket
# GET IP
print("IP of server")
ip = input(" > ")
# SELECT PORT
port = 10000
# SETUP SOCKET
# Create server socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((ip, port))
print(f"Conencted to {ip}:{port}")
# so if there's nothing to read we don't wait too long
sock.settimeout(0.01)
sock.sendall(b"ping!")
ping_string = sock.recv(5).decode()
if ping_string == "ping!":
print("ping!")
else:
print("no ping!")
sock.close()
输出：
服务器：
0: 192.168.56.1
1: 192.168.1.151
> 1
Listening on 192.168.1.151:10000
客户：
Type ip of server

Conencted to 192.168.1.151:10000
ping!
如果这不起作用，请确保您的计算机可以 ping 您的 raspberry pi，反之亦然。进入 CMD（我假设您的 HP PC 是 Windows）并输入 ping ____（将 ____ 替换为您的 raspberry pi.
的内部 IP 地址
如果终端似乎没有在 ping 某些东西，您需要进入您的计算机并raspberry pi找到它们内部 ips，你可以在网上找到如何做。
第 2 步 - 有趣的部分
我们现在要设置您的文件服务器。
服务器代码：
import socket
# OPEN FILE TO SEND ACROSS
with open("filesend.txt", mode="rb") as file:
file_string = file.read()
# FIND IP
# The IP to use will be different depending
# on whether you have WiFi or Ethernet, so
# you need to choose whichever one that is
ips = socket.gethostbyname_ex(socket.gethostname())[-1]
print(*[f"{i}: {j}" for i, j in enumerate(ips)], sep="\n")
ip = ips[int(input(" > "))]
# SELECT PORT
port = 10000
#SETUP SERVER
# Create server socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind((ip, port))
# A queue of 1 clients is more than enough for our application
sock.listen(1)
print(f"Listening on {ip}:{port}")
while True:
try:
(clientsock, address) = sock.accept()
# so if there's nothing to read we don't wait too long
clientsock.settimeout(0.01)
# send length
clientsock.sendall((str(len(file_string)) + ".").encode())
clientsock.sendall(file_string)
print("Sent file!")
response_code = clientsock.recv(1).decode()
if response_code != "0":
print("ERROR! response was not 0")
print(response_code)
clientsock.shutdown(1)
clientsock.close()
except KeyboardInterrupt:
# Add a way to safely exit the infinite loop
break
sock.close()
客户代码：
import socket
# SELECT IP
print("IP of server")
ip = input(" > ")
# SELECT PORT
port = 10000
# SETUP SOCKET
# Create server socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((ip, port))
print(f"Conencted to {ip}:{port}")
# so if there's nothing to read we don't wait too long
sock.settimeout(0.01)
# Get length of file sent across
len_string = ""
c = ""
while c != ".":
c = sock.recv(1).decode()
len_string += c
length = int(len_string[:-1])
file_string = sock.recv(length)
# send a status code back to the server
sock.sendall(b"0")
with open("filerecv.txt", mode="wb") as file:
file.write(file_string)
print(file_string.decode())
sock.close()
输出：
服务器：
0: 192.168.56.1
1: 192.168.1.151
> 1
Listening on 192.168.1.151:10000
客户：
IP of server
> 192.168.1.151
Conencted to 192.168.1.151:10000
THIS IS A TEST!
再次确保您告诉客户端连接的 IP 与您从服务器脚本中提供的列表中选择的 IP 相同。还要确保 ip 地址可以连接到，即如果电脑当前在以太网上，则不要使用 wifi 上的 ip 地址。
希望这对你有用。有什么问题请在评论中留下:)

运行 在您的 PC 上：

host1 = "raspberrypi"
