我正在构建一个渐进的Web应用程序.我从 create-react-app开始使用样板文件.然后我添加了一个Web应用程序清单. app/public/manifest.json { "short_name": "First Contributions", "name": "First Contributions", "ico
          app/public/manifest.json
{
    "short_name": "First Contributions",
    "name": "First Contributions",
    "icons": [
        {
            "src": "/android-chrome-192x192.png",
            "sizes": "192x192",
            "type": "image/png"
        },
        {
            "src": "/android-chrome-256x256.png",
            "sizes": "256x256",
            "type": "image/png"
        }
    ],
    "theme_color": "#ffffff",
    "background_color": "#ffffff",
    "display": "standalone",
    "start_url": "index.html"
} 
 将此链接到index.html
app/public/index.html
<!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">
    <link rel="manifest" href="%PUBLIC_URL%/manifest.json">
    <title>First Contributions</title>
  </head>
  <body>
    <div id="root"></div>
      <script>
        if ('serviceWorker' in navigator) {
          navigator.serviceWorker.register('service-worker.js').catch(function(ex) {
            console.warn(ex);
            console.warn('(This warning can be safely ignored outside of the production build.)');
          });
        }
      </script>
    </body>
  </html> 
 我使用realfavicongenerator.net生成了图标并将它们放在公共目录中.
我正在使用gh-pages部署我的应用程序.当我尝试添加到主屏幕时,我收到以下错误
- android-chrome-192×192.png:1 GET 07001 404 (Not Found)
- Error while trying to use the following icon from the Manifest: 07001 (Download error or resource isn’t a valid image)
- Site cannot be installed: no icon available to display
我认为我在webmanifest中为图标做错了.
您的图标路径引用根目录.将“src”:“/ android-chrome-192×192.png”更改为“src”:“android-chrome-192×192.png”,(不包括/开头).
