英文:
im having problems in setting ip address in python socket library
问题
以下是你提供的代码的中文翻译部分：
服务器端：
import socket
import os
os.system('clear')
s = socket.socket()
ip = 'localhost'
port = 9999
s.bind((ip, port))
s.listen()
print('请等待...')
c, addr = s.accept()
print('有人加入了!')
class color:
GREEN = '3[92m'
RED = '3[91m'
WHITE = '3[0m'
while True:
msg = input(color.RED + '你的消息：')
c.send(msg.encode('utf8'))
print(color.GREEN + c.recv(1024).decode())
客户端：
import socket
import os
os.system('clear')
s = socket.socket()
ip = '192.168.1.3'
port = 9999
s.connect((ip, port))
print('你已连接')
class color:
GREEN = '3[92m'
RED = '3[91m'
WHITE = '3[0m'
while True:
print(color.RED + s.recv(1024).decode())
msg = input(color.GREEN + '你的消息：')
s.send(msg.encode('utf8'))
在这里，你需要为每一侧设置一个IP地址。你尝试了多种方法，但都没有成功。你是否有建议或推荐如何设置IP地址？谢谢。
每种方法的错误：
方法1：将服务器端的IP设置为'localhost'或其他gethostname或gethostbyname：
服务器端可以正常工作，但客户端无法连接。
方法2：将服务器IP地址设置为类似'192.168.0.3'的内容：
服务器端出现错误：OSError: [WinError 10049] 请求的地址在其上下文中无效。
主要修改：
你们建议的各种方法在客户端上都会出现错误：
ConnectionRefusedError: [WinError 10061] 无法建立连接，因为目标计算机拒绝了连接。
英文:
so i want to make a Messenger and i create it with the socket library. by creating a server side and a client side. where two need to be on same internet ( i think so ! )
here is my code:
server side:
import socket
import os
os.system('clear')
s = socket.socket()
ip = 'localhost'
port = 9999
s.bind((ip,port))
s.listen()
print ('please wait...')
c , addr =s.accept()
print ('someone has joined!')
class color :
GREEN = '3[92m'
RED = '3[91m'
WHITE = '3[0m'
while True :
msg = input(color.RED + 'your message: ' )
c.send(msg.encode('utf8'))
print (color.GREEN + c.recv(1024).decode())
client side :
import socket
import os
os.system('clear')
s=socket.socket()
ip='192.168.1.3'
port=9999
s.connect((ip,port))
print('you have been connected' )
class color :
GREEN = '3[92m'
RED = '3[91m'
WHITE = '3[0m'
while True:
print (color.RED + s.recv(1024).decode())
msg = input(color.GREEN + 'your message : ')
s.send(msg.encode('utf8'))
here , i need to set an ip address for each side. i tried all methods but nothing worked.
do you have a recommendation to how to do it ? thanks.
errors on each method :
method 1 : setting server side ip 'local_host' or any other gethostname or gethostbyname :
server side works fine but client side does not connect
method 2 : setting server ip address to something like '192.168.0.3' :
server side makes an error : OSError : [WinError 10049] The requested address is not valid in its context
edit on main :
the methods you guys recommended give an error on client side :
connectionrefusederror: [WinError 10061] no connection could be made
because the target machine refused it

不确定是否正确，但根据大多数示例，人们似乎使用 ip = socket.gethostbyname(socket.gethostname())，这与我对C中套接字的了解相符。因此，尝试将
ip = “localhost” 替换为
ip = socket.gethostbyname(socket.gethostname())。
正如总统建议的那样，在调试期间，您还可以绑定到IP地址“0.0.0.0”，这将侦听所有接口，尽管这可能不会成为问题。
英文:
I don’t know if this is correct, but it seems from most of the examples that people use ip = socket.gethostbyname(socket.gethostname()), which lines up with what I know about sockets in C. So try replacing
ip = “localhost” with
ip = socket.gethostbyname(socket.gethostname()).
As the President recommended, you could also bind to the ip “0.0.0.0” during debugging as it will listen on all interfaces, although this will probably not be an issue.
