I am trying to make basic server with Winsock.
How can I get the values from the arguments in a GET request from the URL?
The URL format: http://124.1.12.23?argument1=value&argument2=value
Code:
Code:#include<io.h>
#include<stdio.h>
#include<winsock2.h>
#pragma comment(lib,"ws2_32.lib") //Winsock Library
int main(int argc , char *argv[])
{
WSADATA wsa;
SOCKET s , new_socket;
struct sockaddr_in server , client;
int c;
char *message;
printf("\nInitialising Winsock...");
if (WSAStartup(MAKEWORD(2,2),&wsa) != 0)
{
printf("Failed. Error Code : %d",WSAGetLastError());
return 1;
}
printf("Initialised.\n");
//Create a socket
if((s = socket(AF_INET , SOCK_STREAM , 0 )) == INVALID_SOCKET)
{
printf("Could not create socket : %d" , WSAGetLastError());
}
printf("Socket created.\n");
//Prepare the sockaddr_in structure
server.sin_family = AF_INET;
server.sin_addr.s_addr = INADDR_ANY;
server.sin_port = htons( 80 );
//Bind
if( bind(s ,(struct sockaddr *)&server , sizeof(server)) == SOCKET_ERROR)
{
printf("Bind failed with error code : %d" , WSAGetLastError());
exit(EXIT_FAILURE);
}
puts("Bind done");
//Listen to incoming connections
listen(s , 3);
//Accept and incoming connection
puts("Waiting for incoming connections...");
c = sizeof(struct sockaddr_in);
while( (new_socket = accept(s , (struct sockaddr *)&client, &c)) != INVALID_SOCKET )
{
puts("Connection accepted");
//Reply to the client
message = "GET / HTTP/1.1 200 OK\r\nDate: Sun, 19 May 2018 08:56:53 GMT\r\nServer: Apache/2.2.14 (Win32)\r\nLast-Modified: Sat, 20 Nov 2004 07:16:26 GMT\r\nETag: \"10000000565a5-2c-3e94b66c2e680\"\r\nAccept-Ranges: bytes\r\nContent-Length: 46\r\nConnection: close\r\nContent-Type: text/html\r\nX-Pad: avoid browser bug\r\n\r\n<html><body><h1>It works!</h1></body></html>\r\n";
send(new_socket , message , strlen(message) , 0);
}
if (new_socket == INVALID_SOCKET)
{
printf("accept failed with error code : %d" , WSAGetLastError());
return 1;
}
closesocket(s);
WSACleanup();
return 0;
}
