微擎请求wx.request封装

app.js里要加入 

var util = require('we7/resource/js/util.js');

//index页面调用
app.util.request({
      url: 'wxapp/home/commend',
      cachetime: '30',
      success: function (res) {
        if (!res.data.message.errno) {
          that.setData({
            commend: res.data.message.message,
          })
        }
      }
    });
