LAUNCHCC3235MOD: Heap memory overflow of in HTTPClient library while making consecutive request

I've just verified there is no memory leak when using the reference httpGet example.

If you are based on this example, you should verify your changes.

Are you allocating data inside the httpPost() ?

Hi Kobi,

Thank you for checking. I also eliminated JSON-related code and tested again.

The HTTP client code works fine. When I add the below code inside the function, it throws an error while making an HTTP connection.

char jtemplate [] =
"{\"Sec\": string,\"Minute\": string,\"Hour\": string,"
"\"Day\": string,\"Month\": string,\"Year\": string, \"Bitrate\": string,\"IfUppgrade\": string,\"IfAlarm\": string,\"Info\": string}";

ret = Json_init(jtemplate,data, strlen(data));
if(ret < 0)
{
LOG_MESSAGE("Json_init failed", ret);
}

Please help me to resolve this issue.

Regards,

Sundar

Hi Kobi,

Here is the Json_init function.

int16_t Json_init(char *template,
char *text,
uint16_t textLen)
{
int16_t retVal;

retVal = Json_createTemplate(&HttpJsonObj.templateHandle, template,
strlen(template));

if(retVal < 0)
{
LOG_MESSAGE("Error: %d , Couldn't create template \r\n",retVal);
return(-1);
}

retVal =
Json_createObject(&HttpJsonObj.jsonObjHandle,HttpJsonObj.templateHandle,
1024);
if(retVal < 0)
{
/* Failed to create an object, free the allocated template */
Json_destroyTemplate(HttpJsonObj.templateHandle);
LOG_MESSAGE("Error: %d , Couldn't create Json object \r\n",retVal);
return(-1);
}

//LOG_MESSAGE("response:%s_1 \r\n", text);

retVal = Json_parse(HttpJsonObj.jsonObjHandle, text,textLen);

if(retVal < 0)
{
LOG_MESSAGE("Error: %d , Couldn't parse"
" the received Json file \r\n",
retVal);

/* Failed to parse the JSON file, free the allocated memory */
Json_destroy();

return(retVal);
}

return(0);
}
