oto餐飲app實時推送訂單給店家程序詳細實現(二)

文接”oto餐飲app實時訂單追蹤系統架構設計”一文。
用戶生成一個外賣訂單後，可以以發短信的方式告知店家有一個訂單，但是短信方式的缺點是非常明顯的，如果想讓用戶和網站知道店家接受訂單和其他的操作就需要網站人工干預，這在智能手機沒有出來之前，那些外賣網站這樣運營是可以理解的，但是智能手機都出來這麼多年了，現在的有些外賣網站還是這麼運營我是難以理解。上次我用“餓了麼”下一個外賣訂單，訂單下了後，餓了麼客服立馬打電話過來確認訂單，我不知道是否確認後他們客服再打電話給店家通知訂單。我對這樣的體驗也是非常不滿意的，不滿意這樣的流程而不是服務。
有點扯遠了。
5.2.1 用戶app提交訂單業務邏輯層:

    order.setHowmuch(total);  
order.setMenu(menuList);  
order.setOrderType(0x001);  //代表的是外賣訂單  
order.setPayType(0x002);    //支付寶網上支付     
order.setUser_id(1/*Integer.parseInt(mApplication.getmUser().getId())*/);  
//把訂單發送出去  
OrderServer orderServer = new OrderServer();  
orderServer.dealOrder(order,new AsyncHttpResponseHandler(){  
     @Override  
     public void onSuccess(String response) {  
            if(!response.equals("0"))  
            {  
                Log.i("TakeawayCommitActivity","提交訂單成功 " + response);  
                startActivity(new Intent(TakeawayCommitActivity.this,PaySuccessActivity.class));  
                finish();  
            }  
     }  
    @Override  
    public void onFailure(Throwable error, String content) {  

    }  
});

網絡通信層

package com.cmyy.httpServer;
import com.cmyy.model.Order;
import com.cmyy.util.HttpUtil;
import com.google.gson.Gson;
import com.loopj.android.http.AsyncHttpClient;
import com.loopj.android.http.AsyncHttpResponseHandler;
import com.loopj.android.http.RequestParams;
import com.loopj.android.http.ResponseHandlerInterface;

//訂單表操作
public class OrderServer {
//生成訂單
public void dealOrder(Order order,AsyncHttpResponseHandler responseHandler)
{
Gson gSon = new Gson();
String json = gSon.toJson(order);
String postUrl=HttpUtil.ORDER_ACTION;
AsyncHttpClient orderRequest = new AsyncHttpClient();
//orderRequest.post(postUrl,responseHandler);
RequestParams prarms = new RequestParams();
prarms.put(“req”, json);
orderRequest.post(postUrl, prarms, responseHandler);
}
}

通信協議模型

5.2.2 web服務端接收訂單
web服務端接收訂單，生成訂單序列號，寫入數據庫保存，並將該訂單必要信息轉發給店家app
web 服務器採用j2ee ssh框架。本來電子商務類網站用php應該好一點吧。
