react link引入外部css样式的坑

2023年12月7日 132次阅读

刚开始的代码是这样的，使用react router4.x写的demo路由跳转后，页面的没有渲染，是因为没有引入外部css文件（或者说引入外部文件路径错误）

 

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <meta name="theme-color" content="#000000">
    <link rel="manifest" href="%PUBLIC_URL%/manifest.json">
    <title>React App</title>
    
    <link rel="stylesheet" href="./css/bootstrap.css">
  </head>
  <body>
    <noscript>
      You need to enable JavaScript to run this app.
    </noscript>
    <div id="root"></div>
  </body>
</html>

 将上面代码（红色部分）的点去掉就可以了，如下所示

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <meta name="theme-color" content="#000000">
    <link rel="manifest" href="%PUBLIC_URL%/manifest.json">
    <title>React App</title>
    
    <link rel="stylesheet" href="/css/bootstrap.css">
  </head>
  <body>
    <noscript>
      You need to enable JavaScript to run this app.
    </noscript>
    <div id="root"></div>
  </body>
</html>
