如何编写程序与客户端和服务器进行通信 [英] how to write program to communicate client and server

问题描述

在C ++中，我正在Ubuntu环境中进行套接字编程，

在这个阶段我正在尝试，

客户端:

in c++, i m doing socket programming in Ubuntu environment,

at this stage i m trying this,

client side:

do
{
  
   printf("Please enter the message:(Enter q for quit) ");
    bzero(buffer,256);
    fgets(buffer,255,stdin);
    n = write(sockfd,buffer,strlen(buffer));
    if (n < 0) 
         error("ERROR writing to socket");
    bzero(buffer,256);
    n = read(sockfd,buffer,255);
    if (n < 0) 
         error("ERROR reading from socket");
   if(buffer[0]=='q') 
     break;
   printf("%s\n",buffer);

}while(1) ;

服务器端:

server side:

do{
     bzero(buffer,256);
     n = read(newsockfd,buffer,255);
     if (n < 0) error("ERROR reading from socket");
     printf("Here is the message: %s\n",buffer);
     if(buffer[0]=='q')    
        break;
    
    printf("Please enter the message:(Enter q for quit) ");
    bzero(buffer,256);
    fgets(buffer,255,stdin);
   
      n = write(newsockfd,buffer,strlen(buffer));
     if (n < 0) error("ERROR writing to socket");
   }while(1); 

现在每个人都可以发送一条消息，然后等待响应以发送更多消息，
我想制作一个客户端服务器，以便他们可以一次通过多条线聊天.就像Yahoo和Facebook聊天一样.

请事先给我一些建议..thanx ....

now each one can send one message then wait for response to send more messages,
i want to make a client server , so that they can chat through multiple lines at once. just like, yahoo and facebook chats..

plz suggest me something.. thanx in advance....

推荐答案

请参阅以下内容:

C ++中的轻量级客户端/服务器套接字类

See this one :

A light-weighted client/server socket class in C++

如果您使用的是Boost，则可以使用

或
http://pocoproject.org/ [ ^ ]

他们也有很多例子.

If you are using Boost you can use

They have many examples also.
