regex - htaccess clean urls & 用 - 替换空格和 %20

Question

我正在努力完成这项工作。目前我的 htaccess 包含以下代码:

#Debugging - Error reporting
php_flag display_startup_errors on
php_flag display_errors on
php_flag html_errors on

#Commpression
<ifmodule mod_deflate.c="">
    <filesmatch ".(js|css|html|png|jpg|jpeg|swf|bmp|gif|tiff|ico|eot|svg|ttf|woff|pdf)$"="">
        SetOutputFilter DEFLATE
    </filesmatch>
</ifmodule>

Options All -Indexes +FollowSymLinks -MultiViews

<IfModule mod_rewrite.c>
    # Turn mod_rewrite on
    RewriteEngine On
    RewriteBase /

    #RewriteCond %{THE_REQUEST} (\s|%20)
    RewriteRule ^([^\s%20]+)(?:\s|%20)+([^\s%20]+)((?:\s|%20)+.*)$ $1-$2$3 [N,DPI]
    RewriteRule ^([^\s%20]+)(?:\s|%20)+(.*)$ /$1-$2 [L,R=301,DPI]

    #RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_URI} !^.*\.(png|jpg|bmp|gif|css|js)$ [NC]
    RewriteRule ^([^/]+/?.+)$ /index.php?req=$1 [L,QSA]

</IfModule>

如果我尝试这个网址，除了 1 件事之外，一切都很好:

http://www.domain.com/ test/

浏览器将其翻译为:http://www.domain.com/%20test/如果路径以空格或 %20 开头，则基本上在域之后，它会失败。谁能指出将删除起始空格的解决方案？

更新

目标:

www.domain.com/   this is a      test      /   hello there     /

或

www.domain.com/   this is a      test      

到

www.domain.com/this-is-a-test/ 或 www.domain.com/this-is-a-test/hello-there

Answer 1

我对两年多前编写该代码感到内疚:P

这段代码可以大大简化:

# remove spaces from start or after /
RewriteRule ^(.*/|)[\s%20]+(.+)$ $1$2 [L]

# remove spaces from end or before /
RewriteRule ^(.+?)[\s%20]+(/.*|)$ $1$2 [L]

# replace spaces by - in between
RewriteRule ^([^\s%20]*)(?:\s|%20)+(.*)$ $1-$2 [L,R]

PS:必须补充一点，您还需要修复这些网址的来源，因为获得这样的网址确实不正常。
