使用cJSON产生json字串

#define BUFFER_SIZE 512
void sendCommand(const char* command, char* function)
{
    cJSON* root = cJSON_CreateObject();
    cJSON_AddItemToObject(root, "command", cJSON_CreateString("function"));
    cJSON* temp = cJSON_CreateObject();
    cJSON_AddItemToObject(root, "content", temp);
    cJSON_AddStringToObject(temp, "name", function);
    char itemName[BUFFER_SIZE] = {0};
    int i = 0;
    memset(itemName, 0, BUFFER_SIZE);
    sprintf(itemName, "bool%d", i);
    cJSON_AddBoolToObject(temp, itemName, true);
    i++;
    memset(itemName, 0, BUFFER_SIZE);
    sprintf(itemName, "int%d", i);
    cJSON_AddNumberToObject(temp, itemName, 1);
    i++;
    memset(itemName, 0, BUFFER_SIZE);
    sprintf(itemName, "double%d", i);
    cJSON_AddBoolToObject(temp, itemName, 1.5);
    i++;
    memset(itemName, 0, BUFFER_SIZE);
    sprintf(itemName, "string%d", i);
    cJSON_AddStringToObject(temp, itemName, urlstr);
    i++;
    memset(itemName, 0, BUFFER_SIZE);
    sprintf(itemName, "null%d", i);
    cJSON_AddStringToObject(temp, itemName, "");
    i++;
    //输出
    DEBUG_TEXT(cJSON_Print(root));
    cJSON_Delete(root);
}
