[SR-Users] json module / quotes in result

I changed the modules/json/json_funcs.c to work-around this issue.  It is
not complete, as it only handles string and int json types:

int json_get_field(struct sip_msg* msg, char* json, char* field, char* dst)
  str json_s;
  str field_s;
  pv_spec_t *dst_pv;
  pv_value_t dst_val;

        if (fixup_get_svalue(msg, (gparam_p)json, &json_s) != 0) {
                LM_ERR("cannot get json string value\n");
                return -1;

        if (fixup_get_svalue(msg, (gparam_p)field, &field_s) != 0) {
                LM_ERR("cannot get field string value\n");
                return -1;

        dst_pv = (pv_spec_t *)dst;

        struct json_object *j = json_tokener_parse(json_s.s);
        enum json_type type = json_object_get_type(json_object_object_get(j,

        if (type == json_type_string) {
                char *value =
(char*)json_object_get_string(json_object_object_get(j, field_s.s));
                dst_val.rs.s = value;
                dst_val.rs.len = strlen(value);
                dst_val.flags = PV_VAL_STR;
        else if (type == json_type_int) {
                int value = json_object_get_int(json_object_object_get(j,
                dst_val.rs.s = '\0';
                dst_val.rs.len = 0;
                dst_val.ri = value;
                dst_val.flags = PV_TYPE_INT|PV_VAL_INT;

        dst_pv->setf(msg, &dst_pv->pvp, (int)EQ_T, &dst_val);

        return 1;

is it correct that the json_get_field returns the quotes from the json


{ "foo": "bar" }

json_get_field("$var(json)", "foo", "$var(result)");

result will contain "bar" with quotes ...

I was a little astonished to see that.
