如何像stackoverflow一样重写SEO友好的url
如果您访问如下网址:http://stackoverflow.com/questions/9155602/ 地址栏将更新为 http://stackoverflow.com/问题/9155602/redirect-existing-file-to-different-url-using-mod-rewrite.这不是用 JavaScript 完成的，也不是用硬刷新完成的，我最好的猜测是它是用 mod_rewrite 完成的；但是，如果没有服务器端用php处理，它怎么知道文章的标题?
If you go to a url like the following: http://stackoverflow.com/questions/9155602/ the address bar will be updated to http://stackoverflow.com/questions/9155602/redirect-existing-file-to-different-url-using-mod-rewrite. This is not done with JavaScript and not with a hard-refresh, my best guess is that it's done with mod_rewrite; however, how would it know the title of the article without server side processing with php?
我刚刚更新了我的网站以使用 SEO 友好的 url，以前是 /shows.php?id=review-1，现在是 /review/1/super-baseball-2020.当涉及到我的重写时，最后的文本实际上并不重要，即:
I just updated my site to use SEO friendly url's, it used to be /shows.php?id=review-1 and now it's /review/1/super-baseball-2020. The text at the end doesn't actually really matter when it comes to my rewrite which is:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([a-z0-9]+)/([0-9]+)/([a-z0-9-]+)?/?$ /shows.php?id=$1-$2 [L,NC]
我目前确保 Google 不会因为重复内容而向我发送信息，并且书签得到正确转发的方法如下:
My current path of making sure Google doesn't hit me for duplicate content, and that bookmarks get forwarded properly is the following:
RewriteCond %{THE_REQUEST} ^GETs/shows.php?
RewriteCond %{QUERY_STRING} (?:^|&)id=review-1(?:&|$) [NC]
RewriteRule ^ /review/1/super-baseball-2020/? [R=301,L,NC]
RewriteCond %{THE_REQUEST} ^GETs/shows.php?
RewriteCond %{QUERY_STRING} (?:^|&)id=review-2(?:&|$) [NC]
RewriteRule ^ /review/2/aero-fighters-2/? [R=301,L,NC]
RewriteCond %{THE_REQUEST} ^GETs/shows.php?
RewriteCond %{QUERY_STRING} (?:^|&)id=review-3(?:&|$) [NC]
RewriteRule ^ /review/3/aero-fighters-3/? [R=301,L,NC]
.... and so on ....
该解决方案非常短视，需要在我的 .htaccess 中放入数千行.
That solution is very shortsighted and is thousands of lines to put into my .htaccess.

mod_rewrite 只能做这么多.另外，你必须更新太多.最好使用脚本处理这些请求.创建一个 .htaccess，类似于你所做的:
mod_rewrite can only do so much. Plus, you'd have to update it too much. It's best to handle these requests with scripting. Create an .htaccess, similar to what you've done:
<IfModule mod_rewrite.c>
RewriteEngine On
#RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /index.php [QSA,L]
</IfModule>
然后在您的 index.php 中，拆分 REQUEST_URI 以解析出 /review/1/，在数据库中查找id 为 1 的评论标题，将其传递给您的友好 URI (slug) 函数，并将其附加到 url，然后重定向.
Then in your index.php, split the REQUEST_URI to parse out the /review/1/, look in the database for the title of the review with id of 1, pass it to your friendly URI (slug) function, and append it to the url, then redirect.
