        {
          "pagePath": "pages/mine/mine",
          "iconPath": "static/icon/zhanghao.png",
          "selectedIconPath": "static/myPersonPink.png",
          "text": "我的"
        }
      ]
    },

tabbar配置minbutton 点击完从哪里跳转? 在App.vue当中配置

onLaunch: function() {
		console.log('App Launch')
		uni.onTabBarMidButtonTap(()=>{
        console.log(123) //你先试试点一下有没有反应 有反应了再跳
        uni.navigateTo({
          url:'/pages/sweepCode/sweepCode'
        })
		  });
      
		},
