C++对比Node.js实现Socket Server 服务端代码

自己搭服务器,由于主机性能太差,运行Java环境太过于勉强,只能跑跑C++。正好顺带着参考网络资料,学习下Node.js。

最近传了两段代码,分别是C++和Node.js实现的Socket服务端

C++代码如下:

#include 
#include           /* See NOTES */
#include 
#include 
#include 
#include 
#include 
#include 

const int MAXLINE = 4096;
const int LISTENQ = 1024;

int main(int argc, char **argv)
{
    int     listenfd, connfd;
    socklen_t len;
    struct  sockaddr_in servaddr, cliaddr;
    char    buff[MAXLINE];
    time_t  ticks;
    bzero(&servaddr, sizeof(servaddr));

    servaddr.sin_family = AF_INET;
    servaddr.sin_addr.s_addr = htonl(INADDR_ANY);
    servaddr.sin_port = htons(8080);

    listenfd = socket(AF_INET, SOCK_STREAM, 0);
    bind(listenfd, (struct sockaddr *)&servaddr, sizeof(servaddr));
    listen(listenfd, LISTENQ);

    for ( ; ; ) {
        len = sizeof(cliaddr);
        connfd = accept(listenfd, (struct sockaddr *) &cliaddr, &len);
        printf("connect from %s, port %d\n",
            inet_ntop(AF_INET, &cliaddr.sin_addr, buff, sizeof(buff)),
            ntohs(cliaddr.sin_port));

        read(connfd, buff, strlen(buff));
        printf("Recive msg: %s\n", buff);

        bzero(buff, sizeof(buff));
        ticks = time(NULL);
        snprintf(buff, sizeof(buff), "%.24s\r\n", ctime(&ticks));
        write(connfd, buff, strlen(buff));
        printf("Send msg: %s\n", buff);

        close(connfd);
    }
    return 0;
}

Node.js代码如下:

var http = require('http');

http.createServer(function (request, response) {
    response.writeHead(200, {'Content-Type': 'text/plain});
    response.end('Hello World\n');
}).listen(8080);

console.log('Server running at http://yixzm.cn:8080/');

总结:

可以看出,同样的功能,代码量差别真的很大。甚至Node.js还多了一个发送http头的功能。
但这也只是浮于表面的一点代码对比,更多的比较还需要继续不断的学习慢慢体会。
