套接字程序挂起

Question

我正在尝试使用 python 进行一些基本的网络连接。下面是进行实际通信的程序片段：

客户端

    # open socket and connect to port
            sock = socket(AF_INET, SOCK_STREAM)
            sock.connect((regHost, regPort))

            # prepare flos for data
            outFlo = sock.makefile(mode='w')
            inFlo = sock.makefile(mode='r')

            outFlo.write(queryString)
            outFlo.flush()
            print "finished writing"

            tmp = inFlo.readline()
            print tmp

            outFlo.close()
            inFlo.close()
            sock.close()

服务器端

        print 'Spawned thread'
        inFlo = self.sock.makefile(mode='r')
        outFlo = self.sock.makefile(mode='w')

        outFlo.write('test writing\n')
        outFlo.flush()

        inFlo.close()
        outFlo.close()
        self.sock.close()
        print 'Closed socket'
        print 'Exiting thread'

该程序似乎挂在客户端对 inFlo.readline() 的调用上。任何帮助将不胜感激。

错误是我忘记在字符串之一的末尾添加 \n 。因此，程序挂在对 inFlo.readline() 的调用上。
