客户端的聊天内容通过json格式封装(包含聊天内容、发送人信息)之后，HTTP请求百度服务器，即请求把该消息发送到指定id的用户，请求成功之后，百度服务器就把我们的信息转发给指定的用户，对应用户再解析json格式的信息，就可以知道该消息来自何处，以及消息内容。(Chat client via json format package (includes chat, sender information), after, HTTP requests Baidu server, which sends the message to the requesting user specified id, after the request is successful, Baidu server took our information forwarded to the designated users, the corresponding user information and then parse json format, you can know that the message came from, and message content.)

利用前面提到的SupplyDepot、Transport和CapableOfBeingRefefuelled类/接口，为Air-plane增加一个main()方法，然后为supplyDepot等增加必要的字段、参数和代码，以便CapableOfBeingRefefuelled能够告诉service（）方法需要加多少油。同时要确保Depot中的油应相应地减少，而实现CapableOfBeingRefefuelledi的类对象应相应地增加。(Using the upplyDepot, Transport and ApableOfBeingRefefuelled classes/interfaces mentioned above, add a main () method to Air-plane, and then add the necessary fields, parameters and codes to supplyDepot, so that CapableOfBeingRefefuelled can tell service () how much fuel the method needs. At the same time, we should ensure that the oil in Depot should be reduced accordingly, and the class objects that implement Capable OfBeingRefefuelledi should be increased accordingly.)
