尝试创建TCP客户端 [英] Trying to create a TCP Client

问题描述

好吧，我最初是用C#编写的，而我的老板希望将其转换为C ++.我完全不知所措，并且在网上超过2个小时没有发现任何有价值的东西.如果您能将我引向一个可行的例子的方向，那将是不错的选择或帮助我.这是我从C#中获得的代码:

 布尔值 bolContinue =  false ;
            
            // 创建用于TCP连接的TCP客户端
            TcpClient tcpClient = 新 TcpClient();
            
            // 将此TCP客户端连接到表单上指定的服务器IP/名称和端口
            tcpClient.Connect(strServer，Convert.ToInt32(strPort));
            // 创建网络流以检索来自TCP客户端的数据
            NetworkStream netStream = tcpClient.GetStream();
            // 创建流读取器以读取网络流
            System.IO.StreamReader strReader = 新 System.IO.StreamReader(netStream);
            如果(tcpClient.Connected)
            {
                bolContinue =  true ;
                // 从流阅读器中读取服务器响应行
                //  MessageBox.Show(strReader.ReadLine()); 
            }
            如果(bolContinue == 真)
            {
                // 将要写入命令的缓冲区
                字节 [] WriteBuffer = 新 字节 [  1024 ];
                ASCIIEncoding enc = 新 System.Text.ASCIIEncoding();
                // 将用户名传递到服务器
                WriteBuffer = enc.GetBytes("  + strUser +  " )；
                netStream.Write(WriteBuffer， 0 ，WriteBuffer.Length);
                // 从流阅读器中读取服务器响应行
                //  MessageBox.Show(strReader.ReadLine()); 
                // 将密码传递到服务器
                WriteBuffer = enc.GetBytes("  + strPass +  " )；
                netStream.Write(WriteBuffer， 0 ，WriteBuffer.Length);
                // 从流阅读器中读取服务器响应行
                //  MessageBox.Show(strReader.ReadLine()); 
                //  MessageBox.Show(即将删除邮件" + intMessage); 
                // 从intMessage中删除消息
                WriteBuffer = enc.GetBytes("  + intMessage +  " )；
                netStream.Write(WriteBuffer， 0 ，WriteBuffer.Length);
                // 从流阅读器中读取服务器响应行
                //  MessageBox.Show(strReader.ReadLine()); 
                // 必须发送退出"以进行删除删除"，否则只会标记为删除
                WriteBuffer = enc.GetBytes(" );
                netStream.Write(WriteBuffer， 0 ，WriteBuffer.Length);
                // 从流阅读器中读取服务器响应
                //  MessageBox.Show(strReader.ReadLine()); 
                // 从服务器注销
                tcpClient.Close();
                //  MessageBox.Show("Connection Closed"，"Info"); 
                返回 真； // 邮件应已删除！
            }
             else  返回  false ; // 消息未删除！ 

这是从删除部分开始的，但是在此示例中，顶部"相同且简单得多.

解决方案

以下是我通常编写TCP客户端的步骤-

//创建一个套接字并连接到服务器

WSAStartup<br />
socket<br />
connect<br />

//发送和接收数据

send<br />
recv

//关闭

closesocket<br />
WSACleanup

您可以在MSDN中查找这些函数的语法和参数. ..

就像，在此站点上，有一个用C ++和C#编写的完善的TCP/IP客户/服务器解决方案，这使我得出结论，some1太懒了，无法进行搜索?
ah ...尝试在搜索框中输入客户端服务器TCP" ...

简单的Google搜索"sockets C ++"将产生大量示例供您调整.

Ok I originally wrote this in C# and my boss would like this converted to C++. I''m at a total loss and over 2 hours on the web has turned up nothing of value. If you could just point me in the direction of a working example that would be great or give me a hand. This is the code I have from C#:

Boolean bolContinue = false;
            
            // create a TCP Client for a TCP Connection
            TcpClient tcpClient = new TcpClient();
            
            // connect this TCP Client to the server IP/name and port specified on the form
            tcpClient.Connect(strServer, Convert.ToInt32(strPort));
            // create a network stream to retreive data from the TCP Client
            NetworkStream netStream = tcpClient.GetStream();
            // create a stream reader to read the network stream
            System.IO.StreamReader strReader = new System.IO.StreamReader(netStream);
            if (tcpClient.Connected)
            {
                bolContinue = true;
                // read the server response line from the streamreader
                //MessageBox.Show(strReader.ReadLine());
            }
            if (bolContinue == true)
            {
                // Buffer to which the commands will be written
                byte[] WriteBuffer = new byte[1024];
                ASCIIEncoding enc = new System.Text.ASCIIEncoding();
                // pass user name to the server
                WriteBuffer = enc.GetBytes("USER " + strUser + "\r\n");
                netStream.Write(WriteBuffer, 0, WriteBuffer.Length);
                // read the server response line from the streamreader
                //MessageBox.Show(strReader.ReadLine());
                // pass the password to the server
                WriteBuffer = enc.GetBytes("PASS " + strPass + "\r\n");
                netStream.Write(WriteBuffer, 0, WriteBuffer.Length);
                // read the server response line form the streamreader
                //MessageBox.Show(strReader.ReadLine());
                //MessageBox.Show("About to delete message " + intMessage);
                //Delete the message from intMessage
                WriteBuffer = enc.GetBytes("DELE " + intMessage + "\r\n");
                netStream.Write(WriteBuffer, 0, WriteBuffer.Length);
                // read the server response line form the streamreader
                //MessageBox.Show(strReader.ReadLine());
                //Must send the Quit to make the delete "take", otherwise it's just marked for deletion
                WriteBuffer = enc.GetBytes("QUIT\r\n");
                netStream.Write(WriteBuffer, 0, WriteBuffer.Length);
                // read the server response from the streamreader
                //MessageBox.Show(strReader.ReadLine());
                // Log off from the server
                tcpClient.Close();
                //MessageBox.Show("Connection Closed","Info");
                return true; // Message should have been deleted!
            }
            else return false; //Message not deleted!

This is from the delete portion, however the "top" is the same and a lot simpler in this example. Thanks in advance!

解决方案

These are the steps I normally do to write a TCP client -

//Create a socket and connect to the server

WSAStartup<br />
socket<br />
connect<br />

// To send and receive data

send<br />
recv

// Shutting down

closesocket<br />
WSACleanup

You can look up the syntax and parameters to these functions in MSDN.

Well... The point is ,, You both have the point , yet , there is small "issue" here ...

Like, there is a perfect client/server over TCP solution written in C++ AND C# right here on this site , which leads me to conclusion that some1 is too lazy to SEARCH ???

Bah ... try typing in "Client server TCP" in search box up there ...

A simple Google search for "sockets C++" will yield plenty of samples for you to adapt.
