打印邮件时如何删除'b'前缀?

标签: python udp

我刚开始用Python编写UDP服务器和客户端。我已经按照教程并添加了一些自己的知识来创建命令行聊天服务器。一切都按计划工作,除了一件事:当我的客户端向服务器发送消息时,服务器在实际消息前面用b'打印它。我的客户将他的消息发回给他,前面是b'。我已经尝试在客户端解码消息,但它从未发送过。我已经尝试在服务器将其发送回来时对消息进行解码,但它从不发送回客户端。我想删除它的原因是因为它破坏了我想要的程序。感谢您的任何帮助!下面是我的代码,首先是服务器,然后是客户端。在我的代码之后,我已经粘贴了一些输出,所以你可以看到我正在谈论的内容。

#Server   

from socket import *
import time

address = input("IP Address: ")
port = input("Port: ")

clients = []

serversock = socket(AF_INET, SOCK_DGRAM)
serversock.bind((address, int(port)))
serversock.setblocking(0)

quitting = False
print("Server is up and running so far.")

while not quitting:
    try:
        data, addr = serversock.recvfrom(1024)
        if "Quit" in str(data):
            quitting = True
        if addr not in clients:
            clients.append(addr)
        print(time.ctime(time.time()) + str(addr) + ": :" + str(data))
        for client in clients:
            serversock.sendto(data, client)
    except:
        pass
serversock.close()
#Client

from socket import *
import threading
import time

tLock = threading.Lock()
shutdown = False

def receiving(name, sock):
    while not shutdown:
        try:
            tLock.acquire()
            while True:
                data, addr = sock.recvfrom(1024)
                print(str(data))
        except:
            pass
        finally:
            tLock.release()

address = input("IP Address: ")
port = 0

server = address, 6090

clientsock = socket(AF_INET, SOCK_DGRAM)
clientsock.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
clientsock.bind((address, int(port)))
clientsock.setblocking(0)

rT = threading.Thread(target=receiving, args=("RecvThread", clientsock))
rT.start()

nick = input("How about we get you a nickname: ")
message = input(nick + "> ").encode()
while message != "q":
    if message != "":
        clientsock.sendto(nick.encode() + "> ".encode() + message, server)
    tLock.acquire()
    message = input(nick + "> ").encode()
    tLock.release()
    time.sleep(0.2)

shutdown = True
rT.join()
clientsock.close()

您发送/接收的数据是字节数组,因此您需要解码它们以获得不带b''的字符串。
您只需使用print(data.decode())即可获得正确的输出。如果您未指定任何编码,则默认行为是使用utf8(有关详细信息,请参阅python doc
