json - cJSON c++ - add item object -

i'm using cjson library (https://github.com/davegamble/cjson). body example request json this:

{   "user": {     "name":"user name",     "city":"user city"     }   } 

i add objects , work:

cjson *root; cjson *user;  root = cjson_createobject(); cjson_additemtoobject(root,"user", user = cjson_createobject()); cjson_addstringtoobject(user, "name", name.c_str()); cjson_addstringtoobject(user, "city", city.c_str()); 

but have body json little different:

{   "user": {     "informations:"{         "name1":"user name1",         "name2":"user name 2"     }   }   } 

and try add object this:

cjson *root; cjson *user; cjson *info;  root = cjson_createobject(); cjson_additemtoobject(root,"user", user = cjson_createobject()); cjson_additemtoobject(user,"informations", info = cjson_createobject()); cjson_addstringtoobject(info, "name", name.c_str()); cjson_addstringtoobject(info, "city", city.c_str()); 

its right way using cjson? because not workin , dont know if problem in c++ or in java client send data c++ server.

thanks lot.

although did not specify, why code not working, code below, should generate sample provided.

#include <iostream> #include "cjson.h"  int main() {   cjson *root;   cjson *user;   cjson *info;    std::string name1 = "user name1";   std::string name2 = "user name 2";    root = cjson_createobject();   cjson_additemtoobject(root,"user", user = cjson_createobject());   cjson_additemtoobject(user,"informations", info = cjson_createobject());   cjson_addstringtoobject(info, "name1", name1.c_str());   cjson_addstringtoobject(info, "name2", name2.c_str());    std::cout << cjson_print(root) << std::endl;   return 0; } 

the cjson documentation seems pretty straightforward , code looks fine. there "test.c" file in cjson sources, can find more code samples how use it.
