      wx.request({
        url: app.globalData.b_info,
        method: 'POST',
        header: {
          'content-type': 'application/x-www-form-urlencoded',
          'cookie': token
        },
        data: {
          token
        },
        //成功后
      success: res => {
        let list = Array.prototype.slice.call(res.data);
        list.forEach(item => {
          let time = util.formatTimeToYmd(item.time)
          item['time'] = time
        })
        this.setData({
          jiaru: list
        })
          wx.setStorageSync('teacherinfo', res.data)
        }
      })
      //引用用{{item.time}}
