React应用程序的网站图标/清单未在gh-pages上显示

Question

我有一个托管在gh-pages上的react/webpack应用程序。

网站图标和清单图标没有显示。

favicon、manifest文件夹和manifest.webmanifest文件都放在client/assets文件夹中。

< 网站图标设置 >

1. app.js

import './assets/favicons/favicon.ico';

2. Webpack.config

 test: /\.(jpe?g|png|gif|ico)$/,
            loader: 'file-loader',
            options: {
              name: devMode ? '[name].[ext]' : '[name].[hash].[ext]',
            },

new HTMLWebpackPlugin({
      template: './public/index.html',
      favicon: './client/assets/favicons/favicon.ico',
    }),

3. index.html

< link rel="apple-touch-icon" sizes="76x76" href="/apple-touch-icon.png" /> < link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png" /> < link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png" /> < link rel="mask-icon" href="/safari-pinned-tab.svg" color="#5bbad5" /> < link rel="shortcut icon" href="/favicon.ico" type="image/png/ico" />

< Manifest设置 >

1. index.html

< link rel="manifest" href="/client/assets/manifest.json" />

2. Webpack配置

[版本] 我添加了CopyWebpackPlugin来复制清单文件夹和manifest.json到dist文件夹。现在Manifest.json文件有效，但图标仍未显示在主屏幕上。

如果您想在浏览器上显示图标，请尝试在 index.html 中添加以下代码：<link rel="shortcut icon" href="%PUBLIC_URL%/assets/favicons/favicon.ico"> - Julian

@Jin 谢谢！那个方法很有效！我尝试了在manifest.webmanifest中使用相同的方法，但仍然没有显示。 - Jiaah

如果您想在浏览器上展示图标，请尝试在index.html文件中进行以下操作。

<link rel="shortcut icon" href="%PUBLIC_URL%/assets/favicons/favicon.ico">
