我有一个index.php文件，在本地主机/项目profile.php文件 我下面code。在我的.htaccess文件有本地主机/项目/ profile.php写的？U = SAM 访问本地主机/项目/ SAM

I have an index.php, profile.php files in localhost/project I've written following code in my .htaccess file to have localhost/project/profile.php?u=sam by visiting localhost/project/sam

RewriteEngine On
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule ^([a-zA-Z0-9_-]+)$ profile.php?u=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ profile.php?u=$1

当我访问的http：//本地主机/项目/ SAM 它diplays我想没有错误。但是，当我访问的http：//本地主机/项目/ SAM / （尾随 / ），它显示纯文本，这意味着没有附加的CSS文件的页面。

When I visit http://localhost/project/sam it diplays what I want without errors. But when I visit http://localhost/project/sam/ (with trailing / ) it displays the page with plain text, that means the css file is not attached.

任何人都知道这样做的原因是什么？帮我解决此问题？

Anyone know the reason for this? And help me to solve this?

推荐答案

您可能正在使用相对URI路径引用这些外部资源。而相对URI解析的基本URI是当前文档的URI，如果没有指定，否则。

You are probably using relative URI paths to reference those external resources. And relative URIs are resolved on a base URI that is the URI of the current document if not specified otherwise.

于是就 /项目/ SAM使用相对URI路径像 CSS / style.css中在这是解决以 /project/css/style.css ;但在使用时， /项目/ SAM / 它解析为 /project/sam/css/style.css 。

So when using a relative URI path like css/style.css on /project/sam it is resolved to /project/css/style.css; but when used on /project/sam/ it is resolved to /project/sam/css/style.css.

您既可以由使用绝对URI路径解决这个问题 /project/css/style.css 或改变使用的 BASE 元素。但需要注意的是，后者将影响的所有的相对URI，而不只是相对的URI路径。

You could fix this by either using the absolute URI path /project/css/style.css or by changing the base URI with the BASE element. But note that the latter will affect all relative URIs and not just relative URI paths.
