我在python中创建了一个客户端/服务器代码。服务器运行良好,并在8000端口上侦听,但当我通过客户端连接到它然后我尝试向服务器发送消息时,我收到以下错误:
Traceback (most recent call last):
File "C:\Users\milad\workspace\NetworkProgramming\client.py", line 26, in <module>
if __name__ == "__main__" : main()
File "C:\Users\milad\workspace\NetworkProgramming\client.py", line 20, in main
TcpSocket.send(sendData)
TypeError: 'str' does not support the buffer interface
我不知道如何解决有关客户端代码的问题。在下面我把客户端代码。我用Python语言编写它。
#!/usr/bin/python3
import socket
from builtins import input
def main():
serverHostNumber = input("Please enter the ip address of the server: \n")
serverPortNumber = input("Please enter the port of the server: \n")
# create a socket object
TcpSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# connection to hostname on the port.
TcpSocket.connect((serverHostNumber, int(serverPortNumber)))
while True:
data = TcpSocket.recv(1024)
print("Server : ", data)
sendData = str(input("Client : "))
TcpSocket.send(sendData)
TcpSocket.close()
if __name__ == "__main__" : main()
答案 0 :(得分:2)
TcpSocket.send(sendData)
看起来send
仅接受bytes
个实例。尝试:
TcpSocket.send(bytes(sendData, "ascii")) #... or whatever encoding is appropriate
答案 1 :(得分:0)
套接字类的python 2文档显示接受字符串参数的.send函数/方法 - 但是如果你查看python 3 documentation for the same class,你会看到.send现在需要将数据作为一个传递给bytearray类型的参数。
更改:
sendData = str(input("Client : "))
到
sendData = str.encode(input("Client : "))
我相信应该做的。
