前端uniapp小程序设置了“navigationStyle“: “custom“，获取每个手机顶部状态栏高度

更改·后的代码   

 <view :style="{height:statusBarHeight+'px'}" class="status"></view>

 第一种：onLoad(){
            this.statusBarHeight = uni.getSystemInfoSync().statusBarHeight
            console.log(this.statusBarHeight,'-')
            // this.statusBarHeight = wx.getSystemInfoSync()['statusBarHeight']

        },
		第二种：onLoad(){
			uni.getSystemInfo({
			    success:(e)=> {
					console.log(e.statusBarHeight;)
			    this.statusBarHeight = e.statusBarHeight;
			  }
			})
			     console.log(this.statusBarHeight,'-')
		},
//css
       .status{
                width: 100%;
                background-color: red;
            }
