我知道python并且正在尝试更复杂的东西。我找到了这段代码，据说它有效。我在客户端的第 14 行收到错误，返回 mrecv ValueError: invalid literal for int() with base 10; ''

我将这两个文件分开并调用服务器，然后调用客户端。当我运行它们时，服务器只说关闭，客户端说
收到->再见！！！什么也没有发生，但是当我在客户端中输入 hello 时，我得到了上面显示的错误。我可能/可能做错了什么，这是我第一次用套接字或服务器或其他东西做任何事情。如果您知道我做错了什么，请提供帮助，如果您有任何其他好的网站或教程给我，我将不胜感激。这是所有代码（不是我的）

服务器

import socket

import time

SIZE = 4

soc = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
soc.bind(('127.0.0.1',5432))
soc.listen(5)

class CThread(threading.Thread):
    def __init__(self,c):
        threading.Thread.__init__(self)
        self.conn = c
        self.stopIt=False

except:
    print 'closing'
thr.stopIt=True
msend(dict['send'],'bye!!!')# for stoping the thread
thr.conn.close()
soc.close()

客户

import socket

SIZE =4
class client(threading.Thread):
    def __init__(self,c):
        threading.Thread.__init__(self)
        self.conn = c
        self.stopIt = False

    def mrecv(self):
        data = self.conn.recv(SIZE)
        self.conn.send('OK')
        return self.conn.recv(int(data))

    def run(self):
        while not self.stopIt:
            msg = self.mrecv()
            print 'recieved-> ',msg

soc1 = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
soc1.connect(('127.0.0.1',5432))
soc1.send('WILL SEND') # telling server we will send data from here

soc2 = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
soc2.connect(('127.0.0.1',5432))
soc2.send('WILL RECV') # telling server we will recieve data from here

def msend(conn,msg):
    if len(msg)<=999 and len(msg)>0:
        conn.send(str(len(msg)))
        if conn.recv(2) == 'OK':
            conn.send(msg)
    else:
        conn.send(str(999))
        if conn.recv(2) == 'OK':
            conn.send(msg[:999])
            msend(conn,msg[1000:]) # calling recursive
thr = client(soc2)
thr.start()
try:
    while 1:
        msend(soc1,raw_input())
except:
    print 'closing'
thr.stopIt=True
msend(soc1,'bye!!') # for stoping the thread
thr.conn.close()
soc1.close()
soc2.close()

我尝试输入一个数字，它给了我同样的错误。当我从线路中取出 int 并运行客户端时，它说它必须是一个数字......还有其他想法吗？

接收方需要 4 个字节的字符串数据来表示要接收的剩余数据的长度。在这种情况下，您的前四个字节不包含有效的文本整数（如“1234”），因此调用int()失败。
