我创建了一个服务工作者和manifest.json文件,以便为Chrome浏览器用户显示"添加到主屏幕"的Web App安装横幅.

它没有按预期工作.

这是我的manifest.json档案

{
  "name": "MySite",
  "short_name": "Mysite",
  "start_url": "./?utm_source=homescreen",
  "icons": [{
      "src": "assets/cacheable/images/shortcut/120x120.png",
      "sizes": "128x128",
      "type": "image/png"
    }, {
      "src": "assets/cacheable/images/shortcut/142x142.png",
      "sizes": "142x142",
      "type": "image/png"
    }, {
      "src": "assets/cacheable/images/shortcut/192x192.png",
      "sizes": "192x192",
      "type": "image/png"
    }, {
      "src": "assets/cacheable/images/shortcut/192x192.png",
      "sizes": "384x384",
      "type": "image/png"
    }],
  "orientation": "portrait" ,
  "background_color": "#fff",
  "display": "standalone",
  "theme_color": "#fff"
}

如果我忘记添加任何内容,请告诉我？
