mod_rewrite 中可能存在无限循环？

Question

我正在修改评论页面的 URL 结构，可以按城市、县、星数和技术人员进行过滤。我想让页面看起来像是静态 HTML 页面，并用连字符替换加号。 我的目标： - 在不修改评论页面的情况下应用新样式 URL，仅修改 htaccess 文件 - 设置从旧式 URL 到新式 URL 的 301 重定向 -将加号转换为连字符

目前评论 URL 如下所示：

domain.com/reviews/?city=City+Name

domain.com/reviews/?city=City+Name&page=2

domain.com/reviews/?county=County+Name

domain.com/reviews/?county=County+Name&page=2

domain.com/reviews/?stars=4

domain.com/reviews/?stars=4&page=2

domain.com/reviews/?tech=Tech+Name

domain.com/reviews/?tech=Tech+Name&page=2

我的目标是让它们看起来像这样（以及 301 旧样式 URL 到新样式 URL）：

domain.com/reviews/city/City-Name.html

domain.com/reviews/city/City-Name/page/2.html

domain.com/reviews/county/County-Name.html

domain.com/reviews/county/County-Name/page/2.html

domain.com/reviews/stars/4.html

domain.com/reviews/stars/4/page/2.html

domain.com/reviews/tech/Tech-Name.html

domain.com/reviews/tech/Tech-Name/page/2.html

城市、县和技术名称并不总是包含加号（即波士顿与纽约+纽约），有些名称不止一个加号。目前，这是我必须用新样式 URL 掩盖旧样式 URL（顺便说一句，这很好用）：

##FIRST PAGE REVIEWS (ie. reviews/city/city-name.html)
RewriteRule ^reviews/(.*)/(.*)\-(.*)\-(.*)\-(.*)\-(.*)\.html "/reviews/?$1=$2+$3+$4+$5+$6" [NC,L]
RewriteRule ^reviews/(.*)/(.*)\-(.*)\-(.*)\-(.*)\.html "/reviews/?$1=$2+$3+$4+$5" [NC,L]
RewriteRule ^reviews/(.*)/(.*)\-(.*)\-(.*)\.html "/reviews/?$1=$2+$3+$4" [NC,L]
RewriteRule ^reviews/(.*)/(.*)\-(.*)\.html "/reviews/?$1=$2+$3" [NC,L]
RewriteRule ^reviews/(.*)/(.*)\.html "/reviews/?$1=$2" [NC,L]

##PAGINATED REVIEWS (ie. reviews/city/city-name/page/2.html)
RewriteRule ^reviews/(.*)/(.*)\-(.*)\-(.*)\-(.*)\-(.*)/page/(.*)\.html "/reviews/?$1=$2+$3+$4+$5+$6&page=$7" [NC,L]
RewriteRule ^reviews/(.*)/(.*)\-(.*)\-(.*)\-(.*)/page/(.*)\.html "/reviews/?$1=$2+$3+$4+$5&page=$6" [NC,L]
RewriteRule ^reviews/(.*)/(.*)\-(.*)\-(.*)/page/(.*)\.html "/reviews/?$1=$2+$3+$4&page=$5" [NC,L]
RewriteRule ^reviews/(.*)/(.*)\-(.*)/page/(.*)\.html "/reviews/?$1=$2+$3&page=$4" [NC,L]
RewriteRule ^reviews/(.*)/(.*)/page/(.*)\.html "/reviews/?$1=$2&page=$3" [NC,L]

我遇到问题的部分是将旧样式 URL 301 转换为新样式 URL。这是我目前所拥有的：

RewriteCond %{QUERY_STRING} (.*)=(.*) [NC]
RewriteRule ^reviews/(.*) /reviews/%1/%2.html? [NS,R=301,NC]

RewriteCond %{QUERY_STRING} (.*)=(.*)&page=(.*) [NC]
RewriteRule ^reviews/(.*) /reviews/%1/%2/page/%3.html? [NS,R=301,NC]

当我尝试这个 FireFox 时，我给出了“页面没有正确重定向”错误。有什么想法吗？

是的，这可能是一个无限循环。使用 THE_REQUEST 代替检查 request line:

RewriteCond %{THE_REQUEST} ^[A-Z]+\ /[^?\ ]*\?([^=]+)=([^\ ]*)&page=([^\ ]*) [NC]
RewriteRule ^reviews/ /reviews/%1/%2/page/%3.html? [NS,R=301,NC]
RewriteCond %{THE_REQUEST} ^[A-Z]+\ /[^?\ ]*\?([^=]+)=([^\ ]*)
RewriteRule ^reviews/ /reviews/%1/%2.html? [NS,R=301,NC]

请注意，如果参数的数量或顺序与此不同，这将失败。
