C++ 多线程客户端未从服务器接收消息

我有一个多客户端服务器程序。客户端控制台需要等待用户输入消息发送到服务器，客户端还需要始终可用于接收来自服务器的消息（这是间歇性的）。为了做到这一点，我尝试在客户端设置两个线程，一个用于接收，一个用于发送

最初，客户机程序（我从中下载）被设计为向服务器发送消息并立即接收回消息。这是初始代码（我没有在这里包括函数，因为我知道它们可以工作，并且函数名是自解释的）：

intmain（）
{
//初始化winsock库
myTcpSocket:：initialize（）；
//获取客户信息
字符串clientName=clientInfo.getHostName（）；
字符串clientIPAddress=clientInfo.getHostIPAddress（）；
//获取服务器的IP地址和名称
字符串serverIPAddress=“”；
readServerConfig（服务器IP地址）；
myHostInfo serverInfo（serverIPAddress，ADDRESS）；
字符串serverName=serverInfo.getHostName（）；
//为客户端创建套接字
mytcpsocketmyclient（PORTNUM）；
//连接到服务器。
myClient.connectToServer（serverIPAddress，ADDRESS）；
int recvBytes=0；
而(1)
{
//向服务器发送消息
char messageToServer[MAX_MSG_LEN+1]；
memset（messageToServer，0，sizeof（messageToServer））；
cout在多线程程序中，您正在创建两个客户端，一个在
sendHandleThread
中，另一个在
rechandlehread
中，以及两个连接。当然，服务器通过客户端消息进入的连接发送其回复消息，即发送到
sendHandleThread
，这不是prepa红色表示接收它，而
recHandleThread
在其连接上没有接收任何内容，因为没有发送任何内容。
要纠正这种情况，您必须只创建一个客户端连接，并让两个线程使用相同的连接。
我猜服务器可能没有向您的客户端发送任何内容，或者没有发送ReceiveMessage（）所需的数据格式。ReceiveMessage（）有多少字节希望在返回之前接收？它实际接收多少字节？您可能希望在ReceiveMessage（）实现中放置一些printf，以查看其中发生的情况…或者运行WireShark以查看哪些字节实际从服务器传入您的计算机，或者两者都是…服务器正在向客户端发送消息（如果接收函数和发送函数都在同一个线程中，我就可以接收到它。只有当它们被分成不同的线程时，程序才能似乎接收不到任何东西。当两个函数在同一个线程中时，服务器正在向客户端发送消息。您如何证明它正在向cli发送消息当函数位于单独的线程中时，是否使用ent？
