MQX 4.1 HTTP Server question

Hi Everyone

I just downloaded and got MQX 4.1 up and running with our new board, however i have noticed something strange.

Before this, we used MQX 4.0 with the older HTTP server implementation, however mqx 4.0 had a function "httpd_get_varval" which allowed me to extract the key/value pairs submitted through the http web form.

I can't seem to find this or an alternative function in the MQX 4.1. Am i missing something? how can i achieve the same functionality so i can port the rest of the code we have?

We are using this for device configuration through the web screens.

Any help will be highly appreciated. I also paste the example code of how the old function was used.

PRIVATE INT CGI_resetFault(HTTPD_SESSION_STRUCT *session)

{

//Get the current configuration for this device

UINT uiLen = 0, i=0;

CHAR sClearFault[6][55] = {0};

CHAR * ucpBuffer = NULL;

INT iError = SUCCESS;

ucpBuffer = NG_MALLOC_ZERO(MAX_HTTP_BUFFER_SIZE);

if(!ucpBuffer){iError = HTML_ERROR_INTERNAL; LRETURN;}

if(!session->request.content_len) {iError = HTML_ERROR_MISSING_OR_INVALID_PARAMS; LRETURN;}

uiLen = session->request.content_len;

uiLen = httpd_read(session, ucpBuffer, (INT)((uiLen > MAX_HTTP_BUFFER_SIZE) ? MAX_HTTP_BUFFER_SIZE : uiLen));

ucpBuffer[uiLen] = 0;

session->request.content_len -= uiLen;

if (

httpd_get_varval(session, ucpBuffer, "Rf_d1", sClearFault[0], sizeof(sClearFault[0])) ||

httpd_get_varval(session, ucpBuffer, "Rf_d2", sClearFault[1], sizeof(sClearFault[1])) ||

httpd_get_varval(session, ucpBuffer, "Rf_d3", sClearFault[2], sizeof(sClearFault[2])) ||

httpd_get_varval(session, ucpBuffer, "Rf_d4", sClearFault[3], sizeof(sClearFault[3])) ||

httpd_get_varval(session, ucpBuffer, "Rf_d5", sClearFault[4], sizeof(sClearFault[4])) ||

httpd_get_varval(session, ucpBuffer, "Rf_d6", sClearFault[5], sizeof(sClearFault[5]))

)

{

iError = HTML_ERROR_MISSING_OR_INVALID_PARAMS; LRETURN; //Missing or invalid params

}

for(i=0;i<6;i++)

{

if(atol(sClearFault[i]))

gsaDevs[i].ucToFaultCnt = 0;

}

END;

CGI_sendHttpResultMessage(session,SUCCESS, DEVICE_STATUS_PAGE_PATH);

iError = session->request.content_len;

return iError;

}

Thank you

I found the answer to the question

In the hval_web demo this function is provided, it just was excluded from the BSP in the new web server implementation

thank you
