weex怎么请求模拟数据

Question

我在本地请求了json数据，并且模拟了接口，怎么放到weex项目中？我尝试放入webpack.dev.js中绑定express，可是还是请求不到。请问怎么解决var app = express()var appData = require('./data.json')console.log(appData);var varieties = appData.varietiesvar recommends = appData.recommendsconsole.log(varieties)var apiRouters = express.Router()apiRouters.get('/varieties', function (req, res) {    res.json({        errno: 0,        data: varieties    })})apiRouters.get('/newsVarieties/recommends', function (req, res) {    res.json({        errno: 0,        data: recommends    })})app.use('/api', apiRouters)
