visual studio怎么写tcp协议?
在 Visual Studio 中,源码可以使用 C++ 或 C# 编写 TCP 协议的源码c 资产管理 源码程序。以下是源码云播源码思路使用 C++ 和 C# 的两种方法:
C++ 实现 TCP 协议
使用 C++ 实现 TCP 协议需要使用 Windows 套接字 API。以下是源码aide找不到源码一个简单的 C++ 示例代码,使用套接字 API 创建 TCP 客户端程序:
#include <iostream>
#include <winsock2.h>
#pragma comment(lib,源码仿滴滴app源码 "ws2_.lib")
int main() {
WSADATA wsaData;
SOCKET ConnectSocket = INVALID_SOCKET;
struct addrinfo *result = NULL, *ptr = NULL, hints;
int iResult;
// 初始化 Winsock
iResult = WSAStartup(MAKEWORD(2, 2), &wsaData);
if (iResult != 0) {
std::cout << "WSAStartup failed: " << iResult << std::endl;
return 1;
}
ZeroMemory(&hints, sizeof(hints));
hints.ai_family = AF_UNSPEC;
hints.ai_socktype = SOCK_STREAM;
hints.ai_protocol = IPPROTO_TCP;
// 解析服务器地址和端口
iResult = getaddrinfo("www.example.com", "", &hints, &result);
if (iResult != 0) {
std::cout << "getaddrinfo failed: " << iResult << std::endl;
WSACleanup();
return 1;
}
// 创建套接字并连接服务器
for (ptr = result; ptr != NULL; ptr = ptr->ai_next) {
ConnectSocket = socket(ptr->ai_family, ptr->ai_socktype, ptr->ai_protocol);
if (ConnectSocket == INVALID_SOCKET) {
std::cout << "socket failed: " << WSAGetLastError() << std::endl;
WSACleanup();
return 1;
}
iResult = connect(ConnectSocket, ptr->ai_addr, (int)ptr->ai_addrlen);
if (iResult == SOCKET_ERROR) {
closesocket(ConnectSocket);
ConnectSocket = INVALID_SOCKET;
continue;
}
break;
}
freeaddrinfo(result);
if (ConnectSocket == INVALID_SOCKET) {
std::cout << "Unable to connect to server" << std::endl;
WSACleanup();
return 1;
}
// 发送和接收数据
iResult = send(ConnectSocket, "GET / HTTP/1.1\r\nHost: www.example.com\r\n\r\n", strlen("GET / HTTP/1.1\r\nHost: www.example.com\r\n\r\n"), 0);
if (iResult == SOCKET_ERROR) {
std::cout << "send failed: " << WSAGetLastError() << std::endl;
closesocket(ConnectSocket);
WSACleanup();
return 1;
}
char recvbuf[];
do {
iResult = recv(ConnectSocket, recvbuf, sizeof(recvbuf), 0);
if (iResult > 0) {
std::cout.write(recvbuf, iResult);
}
else if (iResult == 0) {
std::cout << "Connection closed" << std::endl;
}
else {
std::cout << "recv failed: " << WSAGetLastError() << std::endl;
}
} while (iResult > 0);
// 关闭套接字和清理 Winsock
closesocket(
