我正在尝试制作一个简单的服务器，可以让我测试 Android 的安全功能。我需要开发一个可以打开套接字的应用程序。我在 C 中制作了类似的东西，但我没有看 java。这是C中的应用程序
// simpleserver3.c
#define MY_PORT 9999
#define MAXBUF 99
void indata(int clientfd, struct sockaddr_in client_addr)
{
char buffer[12];
printf("%s:%d connected\n", inet_ntoa(client_addr.sin_addr), ntohs(client_addr.sin_port));
recv(clientfd, buffer, MAXBUF, 0); //this is will overflow the buffer
printf("%X \n", &buffer);
}
int main(int Count, char *Strings[])
{
struct sockaddr_in self, client_addr;
int sockfd,clientfd;
/*---Create streaming socket---*/
if ( (sockfd = socket(AF_INET, SOCK_STREAM, 0)) < 0 ) //socketfd = handle for socket
{
perror("Socket");
exit(errno);
}
/*---Initialize address/port structure---*/
bzero(&self, sizeof(self));
self.sin_family = AF_INET;
self.sin_port = htons(MY_PORT);
self.sin_addr.s_addr = INADDR_ANY;
/*---Bind the structure to the socket handle ---*/
if ( bind(sockfd, (struct sockaddr*)&self, sizeof(self)) != 0 )
{
perror("socket--bind");
exit(errno);
}
/*---Make it a "listening socket"---*/
if ( listen(sockfd, 20) != 0 )
{
perror("socket--listen");
exit(errno);
}
//set socklen_t to length of client address
socklen_t addrlen=sizeof(client_addr);
/*---accept a connection (creating a data pipe)---*/
clientfd = accept(sockfd, (struct sockaddr*)&client_addr, &addrlen); //create handle for communicating
indata(clientfd, client_addr);
close(clientfd);
close(sockfd);
return;
}
任何建议都会很棒，Aneel
