htaccess的URL重写/重定向 - 像Facebook并 [英] htaccess url rewrite/redirect - like facebook does
问题描述
我有一个 www.example.com/mypage.php?id=324
这号324自动递增（即个人是网站的第三百二十四用户），并且每个用户都可以设置自己的用户的URL，存储在MySQL表（字母数字只）。
That number 324 is auto incremented (meaning that person is 324th user of the website), and each user can set own user url, which is stored in mysql table (alphanumeric only).
比方说，用户数324用户URL彼得
Let's say, user number 324 has user url 'peter'
我试图取代 mypage.php？ID = 324 彼得，这样的URL可以像显示 www.example.com/彼得·
I am trying to replace mypage.php?id=324 to peter, so the url can be displayed like www.example.com/peter
但我还是想保持 mypage.php？ID = 324 内部，所以如果有人类型 www.example.com/mypage.php ？ID = 324 ，它可以被重定向到 www.example.com/peter
But I still want to maintain mypage.php?id=324 internally, so if someone types www.example.com/mypage.php?id=324, it can be redirected to www.example.com/peter
我想这是个性化网址如Facebook呢？
I guess this is vanity url like facebook does?
我已经搜索所有网站上，甚至还买了一本有关htaccess的，但我还是没能想出解决办法。请帮我！非常感谢你提前！
I've searched all over the web, and even bought a book about htaccess, but I still couldn't figure this out. Please help me! Thank you so much in advance!
推荐答案
一步URL重写一步...
URL rewriting step by step...
您已经做了这部分 - 你想要 example.com/peter 来是你的用户所看到的
You've done this part - you want example.com/peter to be what your user sees
从技术上讲，可以产生巨大的硬codeD重写规则列表，如：
Technically, you could produce a huge list of hard coded rewrite rules, e.g.
RewriteRule ^peter$ mypage.php?id=324
RewriteRule ^alice$ mypage.php?id=325
RewriteRule ^bob$ mypage.php?id=326
但是，当你有很多用户，这不是特别有效的。
But that's not particularly efficient when you have a lot of users.
您mypage.php会接受一个ID，但你真的需要修改它，以便它可以接受一个可能的用户名（但假定它包含各种垃圾）。比方说，你决定允许其采取另一个查询字符串参数提示。所以，现在你必须得到这样的工作的URL： example.com/mypage.php?hint=peter
Your mypage.php will accept an id, but you'll really need to modify it so that it can accept a possible username (but assume it will contain all sorts of garbage). Let's say you decide to allow it to take another query string argument 'hint'. So now you have to get a URL like this working: example.com/mypage.php?hint=peter
确保您的脚本会产生一个404响应任何的用户名是不理解。
Ensure your script produces a 404 response for any username it doesn't understand.
要做到这一点会是这样的一种方式 - 先的RewriteCond 线确保规则只触发如果请求不符合实际的文件。该重写规则会导致请求被mypage.php处理，但传入其余的URL为提示参数中。该'QSA'的部分是短关于'查询字符串追加'，这意味着任何查询字符串present在原始URL被添加到写规则。在'L'的意思是'最后'，所以没有更多的规则进行调用来处理这个请求。
One way to do this would be something like this - the first RewriteCond line ensures the rule only fires if the request doesn't match an actual file. The RewriteRule will cause the request to be handled by mypage.php, but passing in the rest of the URL as the 'hint' paramter. The 'qsa' part is short for 'query string append', which means any query string present in the original URL is added to the written rule. The 'l' means 'last', so that no further rules are invoked to handle this request.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([a-z]+)$ mypage.php?hint=$1 [qsa, l]
在mypage.php你再看看用户使用的提示。
In mypage.php you'd then look up the user using the hint.
请注意我已经pretty的限制性格局，小写字母只允许序列。这将有助于确保您的脚本不为每个404你的网站可能会产生调用。
Note I've been pretty restrictive in the pattern, only sequences of lower case letters allowed. This will help ensure your script isn't invoked for every 404 your site might produce .
