Question

我的firebase应用仅在本地主机上显示该应用。我已成功初始化并部署了该应用程序，并且希望在何时https://techmatrixzeiterfassung.firebaseapp.com/处显示该应用程序，它仅显示空白页面。我已经替换了index.html，firebase将其替换为原始的

这是我的firebase.json文件

    {
  "hosting": {
    "public": "public",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ]
  }
}

当我在Chrome中打开开发工具时，可以看到您的代码。

<!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.png">
    <!--
      Notice the use of %PUBLIC_URL% in the tag above.
      It will be replaced with the URL of the `public` folder during the build.
      Only files inside the `public` folder can be referenced from the HTML.
      Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
      work correctly both with client-side routing and a non-root public URL.
      Learn how to configure a non-root public URL by running `npm run build`.

      var WebFontConfig = {
        google: { families: [ 'Roboto:400,300,500:latin' ] }
      };
      (function() {
        var wf = document.createElement('script');
        wf.src = ('https:' == document.location.protocol ? 'https' : 'http') +
        '://ajax.googleapis.com/ajax/libs/webfont/1/webfont.js';
        wf.type = 'text/javascript';
        wf.async = 'true';
        var s = document.getElementsByTagName('script')[0];
        s.parentNode.insertBefore(wf, s);
      })();
    </script>

    <div id="root"></div>
    <!--
      This HTML file is a template.
      If you open it directly in the browser, you will see an empty page.
      You can add webfonts, meta tags, or analytics to this file.
      The build step will place the bundled scripts into the <body> tag.
      To begin the development, run `npm start`.
      To create a production bundle, use `npm run build`.
    -->
  </body>
</html>

实际上，索引中没有任何HTML可以在浏览器上显示。我从开发工具中添加了一个div，它按预期显示

控制台中显示错误：

/％PUBLIC_URL％/ favicon.png：1无法加载资源：服务器响应状态为400（）

也许您希望在屏幕上看到一个图标？

Firebase应用程序仅可在localhost上运行，初始化和部署均成功
