在 Linux C++ 开发中进行数据推送,通常需要使用套接字编程(Socket Programming)和网络编程技术
#include <sys/socket.h>
int sockfd = socket(AF_INET, SOCK_STREAM, 0);
struct sockaddr_in server_addr;
memset(&server_addr, 0, sizeof(server_addr));
server_addr.sin_family = AF_INET;
server_addr.sin_port = htons(PORT); // 端口号
inet_pton(AF_INET, "服务器IP地址", &server_addr.sin_addr);
connect(sockfd, (struct sockaddr*)&server_addr, sizeof(server_addr));
const char* message = "Hello, Server!";
send(sockfd, message, strlen(message), 0);
char buffer[1024];
int received_data = recv(sockfd, buffer, sizeof(buffer) - 1, 0);
buffer[received_data] = '\0';
close(sockfd);
以下是一个简单的 Linux C++ 服务器端示例:
#include <iostream>
#include <sys/socket.h>
#include <netinet/in.h>
#include <unistd.h>
int main() {
int server_fd, client_fd, addr_len;
struct sockaddr_in server_addr, client_addr;
char buffer[1024] = {0};
server_fd = socket(AF_INET, SOCK_STREAM, 0);
memset(&server_addr, 0, sizeof(server_addr));
server_addr.sin_family = AF_INET;
server_addr.sin_addr.s_addr = INADDR_ANY;
server_addr.sin_port = htons(8080);
bind(server_fd, (struct sockaddr*)&server_addr, sizeof(server_addr));
listen(server_fd, 3);
addr_len = sizeof(client_addr);
client_fd = accept(server_fd, (struct sockaddr*)&client_addr, (socklen_t*)&addr_len);
read(client_fd, buffer, sizeof(buffer) - 1);
std::cout << "Received from client: " << buffer << std::endl;
send(client_fd, "Hello, Client!", strlen("Hello, Client!"), 0);
std::cout << "Sent to client: Hello, Client!" << std::endl;
close(client_fd);
close(server_fd);
return 0;
}
请注意,这只是一个简单的示例,实际应用中可能需要处理错误、多线程或多进程通信等复杂情况。在实际项目中,你可能需要使用更高级的库(如 Boost.Asio)来简化网络编程。
