onPullDownRefresh(){
　　console.log('--------下拉刷新-------')
　　wx.showNavigationBarLoading() //在标题栏中显示加载
　　wx.request({
     url: 'https://URL',
     data: {},
     method: 'GET',
     // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT
     // header: {}, // 设置请求的 header
     success: function(res){
      // success
     },
     fail: function() {
      // fail
     },
     complete: function() {
      // complete
      wx.hideNavigationBarLoading() //完成停止加载
      wx.stopPullDownRefresh() //停止下拉刷新
   }
})
