如何通过Restfb获得Facebook页面对话？

Question

I working on an application that manages a facebook page. I have to load the private conversations on this page. I am using restfb graph api for this purpose. I tried some examples but they are not working. Below is code that i am trying for your reference.

Connection<Conversation> conversations = facebookClient.fetchConnection("me/conversations", Conversation.class);

for(List<Conversation> conversationPage : conversations) {
  for(Conversation conversation : conversationPage) {
    System.out.println(conversation);
    System.out.println(conversation.getUnreadCount());

    Message lastMessage = null;
    for (Message message : conversation.getMessages())
    {
      System.out.println("Message text = " + message.getMessage());
      System.out.println("Message unread = " + message.getUnread());
      System.out.println("Message from = " + message.getFrom().getName());
      System.out.println("Message to = " + message.getTo().get(0).getName());
      System.out.println("Message unseen = " + message.getUnseen());
      lastMessage = message;
    }
  }
}

System.out.println(conversation.getUnreadCount());

While i have manage unread messages at my page. I require your help to resolve this issue. Please advice.

Thanks CBroe , for your help. I got the answer by debugging facebook graph api. here is the code which i have used.

Connection<Conversation> conversations = facebookClient.fetchConnection("me/conversations", Conversation.class);
     for(List<Conversation> conversationPage : conversations) {
        for(Conversation conversation : conversationPage) {
          String id = conversation.getId();
          Connection<Message> messages = facebookClient.fetchConnection(id + "/messages", Message.class, Parameter.with("fields", "message,created_time,from,id"));
        }
     }
