微信小程序背景图片 模拟器正常显示 真机无法显示

<viewclass="container-count"style="background-image:url('mage/login/bg.png');background-size:cover;"></view>

把图片转成base64

完事

this.setData({bgImg: "data:image/png;base64," + wx.getFileSystemManager().readFileSync("/image/login/bg.png","base64")})

<view class="container-count" style="background-image: url({{bgImg}});background-size:cover;"></view>
