Hi,

Thanks for the httpclient code, i am using your code to get data form server..

I am making a HTTP request to a server and I am getting data from the database. Now I want to parse the JSON data and get the data into variables like this:

std::vector * buffer = response->getResponseData();
char * concatenated = (char *) malloc(buffer->size() + 1);
std::string s2(buffer->begin(), buffer->end());
strcpy(concatenated, s2.c_str());

Json * json = Json_create(concatenated);
std::string test1 = Json_getString(json, "id", "default");
std::string test2 = Json_getString(json, "pass", "default");

CCLog("HTTP Response : id : %s", test1);
CCLog("HTTP Response : pass : %s", test2);

But I am getting an error on:

Json Json_getItem (Json *object, const char string) {
Json *c = object->child; //error on this line -- exc_bad_access
while (c && Json_strcasecmp(c->name, string))
c = c->next;
return c;
}
When I log...

log("%s",concatenated);
...it outputs data like this:

id:mt pass:thkr

that means data is coming from server..

So how to parse data and get id, pass value in different variable so i can use it later in my code..plz help already posted in cocos forum but no reply..

use rapid json to parse data.

how can i parse header ???
