Http Client Hi Everyone
I am developing for Linux and am looking for a way to retrieve HTTP pages from the internet, I have found a couple of tutorials that have shown me how to get the basics sorted out:
Whilst this works to some degree it does not seem to actually get the http page I am after (for example Google and I get:Code:int sockid; int bufsize; char buffer[2048]; struct sockaddr_in socketaddr; struct hostent *hostaddr; struct servent *servaddr; struct protoent *protocol; bool threadActive = true; while(threadActive) { if (!(hostaddr = gethostbyname(my_data->seed))) { fprintf(stderr, "Error resolving host: %s", my_data->seed); exit(1); } // if else printf("%s", hostaddr->h_name); /* clear and initialize socketaddr */ memset(&socketaddr, 0, sizeof(socketaddr)); socketaddr.sin_family = AF_INET; /* setup the servent struct using getservbyname */ servaddr = getservbyname(SERVICE, PROTOCOL); socketaddr.sin_port = servaddr->s_port; memcpy(&socketaddr.sin_addr, hostaddr->h_addr, hostaddr->h_length); protocol = getprotobyname(PROTOCOL); sockid = socket(AF_INET, SOCK_STREAM, protocol->p_proto); if (sockid < 0) { fprintf(stderr, "Error creating socket."); exit(1); } // if if(connect(sockid, (struct sockaddr*)&socketaddr, sizeof(socketaddr)) == -1) { fprintf(stderr, "Error connecting."); exit(1); } // if /* send our get request for http */ if (send(sockid, GET, strlen(GET), 0) == -1) { fprintf(stderr, "Error sending data."); exit(1); } // if /* read the socket until its clear then exit */ while ( (bufsize = read(sockid, buffer, sizeof(buffer) - 1))) { write(1, buffer, bufsize); } // while close(sockid);
returned instead of the actual google homepage. I think It's got something to do with the way I cam creating and directing the socket to the google address, in that its using it as a address, where in actual fact I want it to be using the http address / http protocol (perhaps).HTTP/1.1 302 Found
