var app = express() //从这后面开始加
 
var appData = require(‘../data.json‘);
 
var seller = appData.seller;
 
var goods = appData.goods;
 
var ratings = appData.ratings;
 
var apiRoutes = express.Router();
 
apiRoutes.get(‘/seller‘,function (req,res) {
 
 res.json({
 
  errno:0,
 
  data:seller
 
 });
 
}); 

apiRoutes.get(‘/goods‘,function (req,res) {
 
 res.json({
 
  errno:0,
 
  data:goods
 
 });
 
});
 
apiRoutes.get(‘/ratings‘,function (req,res) {
 
 res.json({
 
  errno:0,
