http get request to google failed

[oscargarciaabad]

Hi,

I'm trying to do an Http get request to google, but once I have sent the request I do not receive any answer from google. I'm using MXQ 4.0 on TWR-K53N512. My code is the next one:

#define HTTP_GOOGLE_COM                    "GET / HTTP/1.0\r\n\r\n"

#define IP_ADDRESS_GOOGLE_COM        IPADDR(173,194,34,244)

void SocketClientTask(uint_32 PrivateData) {

     uint_32 Client, Error;

     int_32 BytesToProcess, BytesSent;

     sockaddr ClientAddress, ServerAddress;

     uint_16 ServerAddressLength;

     char RxBuffer[100];

     uint_32 SocketOption = FALSE;

     uint_32 SocketOptionLength;

     Client = socket(PF_INET, SOCK_STREAM, 0);

     memset((char *) &ClientAddress, 0, sizeof(ClientAddress));

     ClientAddress.sin_addr.s_addr = IPADDR(10,0,0,206);// "This is my IP"

     ClientAddress.sin_family = AF_INET;

     ClientAddress.sin_port = SERVER_PORT + 1;

     SocketOptionLength = sizeof(SocketOption);

     Error = setsockopt(Client, SOL_TCP, OPT_RECEIVE_NOWAIT, &SocketOption, SocketOptionLength);

     if(Error != RTCS_OK) {

          printf("setsockopt() failed with error %lx” --> Client Exiting\n", Error);

          return;

     }

     Error = bind(Client, &ClientAddress, sizeof(ClientAddress));

     if(Error != RTCS_OK){

          printf("Failed to bind Client, error %lx\n", Error);

          return;

     }

     memset((char *) &ServerAddress, 0, sizeof(ServerAddress));

     ServerAddress.sin_addr.s_addr = IP_ADDRESS_GOOGLE_COM;

     ServerAddress.sin_family = AF_INET;

     ServerAddress.sin_port = 80;

     ServerAddressLength = sizeof(ServerAddress);

     Error = connect(Client, &ServerAddress, ServerAddressLength);

     if(Error != RTCS_OK){

          printf("connect to server failed with error code %lx\n", RTCS_geterror(Client));    

          return;

     }

     printf("Connected\n");

     memset(RxBuffer, 0, sizeof(RxBuffer));

     sprintf(RxBuffer, "%s", HTTP_GET_GOOGLE_COM);

     BytesSent = send(Client, RxBuffer,strlen(RxBuffer), RTCS_MSG_BLOCK);

     printf("HTTP_GET_GOOGLE_COM sent %ld bytes\n", BytesSent);

     while(1) {

          BytesToProcess = recv(Client, RxBuffer, sizeof(RxBuffer), RTCS_MSG_PEEK);

          if(BytesToProcess > 0) {

               recv(Client, RxBuffer, BytesToProcess, 0);    

               while(BytesToProcess > 0) {

                    printf("%c", RxBuffer[BytesToProcess]);    

                    BytesToProcess--;

               }

               memset(RxBuffer, 0, sizeof(RxBuffer));

          }

          else if(BytesToProcess == RTCS_ERROR) {

               printf("ERROR!!!!\n");

               return;

          }

     }

}

What I'm doing wrong?

Thanks in advance.

Óscar.

Hi Oscar,

I believe you are missing part of the header. I can only see the GET string in your code. Take a look to the appnote http://cache.freescale.com/files/microcontrollers/doc/app_note/AN4417.pdf I believe you will find educative in the web client topic.

Hope this helps.
