Question

我在Mac上使用python，出于某种原因，当我尝试运行服务器时，连接被拒绝了。以下是客户端和服务器的代码。我试图让用户可以通过客户端登录到登录系统。我还希望能够这样做，以便当用户登录帐户时，他们的密码会自动保存到.txt文档中。有谁知道我怎么做到这一点？谢谢阅读。

客户代码：

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)



print("Waiting for connection")



s.connect(('127.0.0.1', 4000))  

data = s.recv(1024).decode()#max number of bytes recv

print ("data from server", data)

message = str(input("Send: ->"))

s.send(message.encode())

s.close()

input("\n\n press enter to close")



users = {}

status = ""



def displayMenu():

    status = input("Are you registered user? Please write yes or no. Press q to quit")

    if status == "yes":

        oldUser()

    elif status == "no":

        newUser()



def newUser():

    createLogin = input("Create login name: ")



    if createLogin in users:

        print("\nLogin name already exist!\n")

    else:

        createPassw = input("Create password: ")

        users[createLogin] = createPassw

        print("\nUser created\n")



def oldUser():

    login = input("Enter login name: ")

    passw = input("Enter password: ")



    if login in users and users[login] == passw:

        print("\nLogin successful! Your credentials have been saved.\n")

    else:

        print("\nUser doesn't exist or wrong password!\n")



while status != "q":

    displayMenu()

服务器代码：

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

print("Listening: ")

s.bind(('127.0.0.1', 4000))
s.listen(10) #listen to 1 connection at a time
c, addr = s.accept()  
print ("Connection from: ", addr)
message = input("Send: ->")
c.sendall(message.encode())
data = c.recv(1024).decode()#max number of bytes recv
print("data from client ", data)

c.close()
input("\n\n press enter to close")

在单独的shell中打开两个程序首先运行服务器程序然后在服务器程序仍在运行时运行客户端程序。

它将解决连接拒绝错误让我知道它是否有效：）
