我是网络编程的初学者,我有一个项目,我必须创建一个系统资源管理器。这意味着我将能够在浏览器中编写带有目录的http请求,如果与服务器的连接成功,则将打开上述目录中的文件。
int main(int argc, char** argv)
{
typedef struct tcpip_connection
{
int connfd;
struct sockaddr_in peer_addr;
} tcpip_connection;
int s_socket, *fd, port;
char buffer[256];
struct sockaddr_in lis_addr;
struct sockaddr_in peer_addr;
int sopt = 1, n;
s_socket=socket(AF_INET, SOCK_STREAM, 0);
if(s_socket<0){
printf("error: the socket was not created!");
}
if(setsockopt(s_socket , SOL_SOCKET, SO_REUSEADDR, &sopt, sizeof(sopt))){
printf("Setsokopt error!");
}
memset(&lis_addr, 0, sizeof(lis_addr));
lis_addr.sin_family = AF_INET;
lis_addr.sin_addr.s_addr = htonl(INADDR_ANY);
lis_addr.sin_port = htons(port);
if ( bind( s_socket, (struct sockaddr*) &lis_addr, sizeof(lis_addr) ) < 0 ){
perror(NULL);
exit(-1);
}
if(listen(s_socket,15)<0){
perror("server.listen");
}
socklen_t peer_addrlen;
while(1){
if((fd = malloc(sizeof(int))) == NULL){
fprintf(stderr, "Out of memory\n");
abort();
}
*fd=accept(s_socket, (struct sockaddr*)&peer_addr,&peer_addrlen);
if(fd<0){
if( errno==EINTR /* Call interrupted by signal */
|| errno==ECONNABORTED /* connection was aborted */
|| errno==EMFILE /* per-process limit of open fds */
|| errno==ENFILE /* system-wide limit of open fds */
|| errno==ENOBUFS /* no space for socket buffers */
|| errno==ENOMEM /* no space for socket buffers */
|| errno==EPERM /* Firewall blocked the connection */
)
continue;
}
}
if(errno == EBADF)
break; /* return, the server_socket is closed */
}
bzero(buffer,1024);
n = read(*fd,buffer,1023);
if (n < 0)
{
perror("ERROR reading from socket");
exit(1);
}
printf("Here is the message: %s\n",buffer);
/* Write a response to the client
n = write(*fd,"I got your message",18);
if (n < 0)
{
perror("ERROR writing to socket");
exit(1);
}
return 0;*/
}
我不知道我的代码是否有任何问题,但主要问题是我不知道如何让浏览器与服务器连接。有什么我必须在浏览器中写或我是否需要添加一些额外的代码?
答案 0 :(得分:0)
您忘记初始化端口变量。在调用bind并侦听之前,请尝试设置port = 8080
。
然后,在您的浏览器中,转到http://localhost:8080/
,它应该连接。
