I faced the same issue while configuring Postfix Admin 3.2. According to the official documentation, the whole Postfix Admin content should be extracted into a separate directory, i.e. /srv/postfixadmin and not the document root. Only the /srv/postfixadmin/public directory should be symlinked into /var/www/html document root. I have just extracted the whole content into /var/www/html. Having played with Nginx server block settings, I managed example.com/postfixadmin resolving from /var/www/html/postfixadmin/public. Nevertheless, images and CSS were not available with 404 status code. The stylesheets were broken. I got the error message OP quoted with respective 404 entries in access log.

在我的情况下，我只是移动/var/www/html/postfixadmin到/srv/postfixadmin和ln -s /srv/postfixadmin/公共/var/www/html/postfixadmin。这完全解决了问题。 这是参考资料。

使用ReactJs，当我添加样式文件到index.html使用相对链接，如

<link rel="stylesheet" href="./css/style.css"> .

然后我导航到一条路线，说;localhost:3000/artist和刷新，我得到错误。

错误消失后，我取代相对链接与绝对链接说;

<link rel=“stylesheet” href=“http://localhost/project/public/css/style.css”。

答案可以在上面给出。我也遇到过同样的问题，但无法解决。确保添加外部js文件为

<script src="main.js"></script>

当我从谷歌CDN提供的css样式表的css链接中删除协议时，就发生了这种情况。

这不会产生错误:

<link rel="stylesheet" href="//fonts.googleapis.com/css?family=Architects+Daughter">

但是这会给出错误资源解释为样式表，但传输MIME类型text/html:

<link rel="stylesheet" href="fonts.googleapis.com/css?family=Architects+Daughter">

使用的反应

我在我的react profile应用程序中遇到了这个错误。我的应用程序表现得有点像它试图引用一个不存在的url。我相信这与webpack的行为有关。

如果你在公用文件夹中链接文件，你必须记住在资源之前使用%PUBLIC_URL%，就像这样:

<link type="text/css" rel="stylesheet" href="%PUBLIC_URL%/bootstrap.min.css" />
