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.

Regards,

Garabo
