ZBlog系统强制网站目录链接统一加斜杠访问

通常情况下，url在末尾处是否加上斜杠“/”，对用户访问是没有太大影响的，大多数的Web 服务器均能正确解析，在传统意义上说，url末尾是没有反斜杠的，有没有反斜杠的意义在于该 url 是指向一个文件还是一个目录，举个例子：

https://www.umtheme.com/theme
https://www.umtheme.com/theme/

url末尾带斜杠 / 的是指向目录/theme/，不带的是文件/theme，是两个不同的地址，一般来说，索引页面（如文章列表或分类）作为网站目录，而内容页面作为文件

对于服务器来说，如果访问目录，则会根据规则访问该目录下的默认文件（index.html、index.htm、index.php之类）。如：访问/theme/服务器会寻找/theme/index.html文件，而访问/theme服务器则会寻找/theme文件，如果没有查询到该目录下的文件时，有可能导致web服务器不能正确解析而出现返回404 错误，这时就要对链接进行定向处理让目录统一加上斜杠访问。

网站目录链接统一加斜杠的方法：

Apache .htaccess

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^\.]+[^/])$ /$1/ [L,R=301]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

Nginx

if (!-f $request_filename){
   rewrite ^/([^\.]+[^/])$ $scheme://$host/$1$2/ permanent;
}
if (-f $request_filename/index.html){
   rewrite (.*) $1/index.html break;
}
if (-f $request_filename/index.php){
   rewrite (.*) $1/index.php;
}
if (!-f $request_filename){
   rewrite (.*) /index.php;
}

在规则中加上以上代码即可给目录自动加上斜杠访问，防止出现404错误问题。
