to the server....
the server program is..


#include <iostream>





#include "jmp_tcp/TcpServer.h"
#include "3d_connexion_poc/Protocol.h"
#include "cfsocket/CFTcpServer.h"

using namespace jmp_tcp;

class ServerTest : public TcpServer

int length = recv(cfd, buff, sizeof(buff), 0);
std::cout << " length " << length << std::endl;

if (length <=0) break;
else

}

};

void dynamicPort()
{

int port = 8000;
while(!server.setup(port) && port <9000)
{

CFRunLoopRun();
}

int main (int argc, char * const argv[])
{
//staticPort();
//dynamicPort();
//testProtocol();
testCFTcpServer();

return 0;
}


and the client program is..


#include <iostream>
#include "jmp_tcp/TcpClient.h"
using namespace jmp_tcp;

int main (int argc, char * const argv[]) {
    TcpClient client;
    if(!client.connectByName("localhost", 8000))
    {
        std::cout << std::endl << "client connection failed"<< std::endl;
        return 0;
    }
    std::string msg;
    char buff[256];
    while(msg != "by")
    {
        std::cin >> msg;
        if(msg.length() >0)
        {
            bzero((char *) buff, sizeof(buff));
            if (!client.send(msg.c_str(), msg.length()))
            {
                std::cout<< std::endl << "send error";
                break;
            }
            int len = client.read(buff, sizeof(buff));
            std::cout << std::endl << len << " " << buff << std::endl;
            if (len <=0) break;
            else
            {
                std::cout << std::endl << len << " " << buff << std::endl;
            }
        }
    }
    client.disconnect();



返回0;
}


我应该如何链接..



return 0;
}


how should i link this..

推荐答案

if(！(server.setup(port)))
{
std :: cout<< std :: endl<< 服务器设置失败"；
返回；
}

如果需要将其发送到服务器，它必须来自客户端应用程序.

您的客户端应用程序中没有Mouse3D变量.如:

if(!(server.setup(port)))
{
std::cout << std::endl << "server setup failed";
return;
}

If you need to send it to the server it must come from the client app.

You don''t have a Mouse3D varible in you client app. such as:

Mouse3D *d = ( Mouse3D* ) inContext;
if (!d) return;


然后，您可以用文本填充std :: cout缓冲区，然后将其发送到服务器.

或者，您可以将* d设为全局变量，并以这种方式使用它.


Then you might fill the std::cout buffer with the text then send that to the server.

Or you might make *d a global varible, and work with it that way.


这篇关于TCP链接的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
