如何将TCP客户端连接到服务器并发送到服务器端？出现错误，无法成功运行代码。

Question

我正在学习TCP，正在尝试一个客户机/服务器程序。我的服务器端正在工作，但在客户端，我无法成功连接到服务器端。你知道吗

客户端的错误代码

第一个错误：

回溯（最近一次呼叫）： “文件”tcpclient.py文件，第13行，在 客户端套接字.connect（（服务器名，服务器端口）） TypeError:应为str、bytes或bytearray，而不是list

第二个错误：

回溯（最近一次呼叫）： “文件”tcpclient.py文件，第34行，在 客户端套接字.send(clientSentence.encode（），服务器地址） TypeError:需要整数（获取类型tuple）

服务器代码：此代码成功运行。你知道吗

import sys
from socket import*

serverSocket = socket(AF_INET, SOCK_STREAM)
serversys = sys.argv

if len(serversys) == 1: 
    serverPort = 9999
else:
    serverPort = serversys[1]
    serverPort = int(serverPort)

serverSocket.bind(('', serverPort)) 
serverSocket.listen(1)
print ("The server is ready to receive.")

while True:
    connectionSocket, addr = serverSocket.accept()
    print ("Connection accepted from: ", addr)

    clientSentence = connectionSocket.recv(1024).decode()


    clientSentence, clientAddress = serverSockset.recv(1024)
    clientSentence.decode()
    connectionSocket.close()

    if clientSentence[0].decode() == 'U':
        serverSentence = clientSentence.upper()
        connectionSocket.send(serverSentence[1:].encode(), clientAddress)
        connectionSocket.close()
    elif clientSentence[0].decode() == 'L':
        serverSentence = clientSentence.lower()
        connectionSocket.send(serverSentence[1:].encode(), clientAddress)
        connectionSocket.close()
    elif clientSentence[0].decode() == 'I':
        serverSentence = clientSentence.title()          
        connectionSocket.send(serverSentence[1:].encode(), clientAddress)
        connectionSocket.close()

客户端：这是发生这两个错误的地方。你知道吗

import sys
from socket import*

clientSocket = socket(AF_INET, SOCK_STREAM)

clientsys = sys.argv
serverName = clientsys[1:]
serverPort = clientsys[2:]

clientSocket.connect((serverName, serverPort)) #First Error

serverPort = [int(serverPort) for serverPort in serverPort]
serverAddress = (serverName, serverPort)

sentenceChoice = input("Enter U for UPPERCASE SENTENCE, L for lowercase sentence, \nor I for Initial Caps Sentence: ")
sentence = input("Enter sentence: ")

clientSentence = sentenceChoice+sentence

clientSocket.send(clientSentence.encode(), serverAddress) #Second Error
serverSentence = clientSocket.recv(1024)
print('From Server: ', serverSentence.decode())
clientSocket.close()

Answer 1

你确定它应该是clientsys[2:]而不是clientsys[2]吗？你知道吗
