mod_rewrite的：传递路径和放大器;查询字符串URL作为参数 [英] mod_rewrite: Pass the path & query string URL as a parameter

问题描述

我使用mod_rewrite为pretty重写的URL由一个Spring 2.5应用程序所支持的格式。

I'm using mod_rewrite to rewrite pretty URLs to a form supported by a Spring 2.5 application.

e.g. /category/cat1?q=x   =>  /controller?category=cat1&q=x

不过从我的控制，我想知道的请求来自原始URL（这样我就可以在需要生成一个链接）。一般是需要所有网页的这种做法，因此很难很难code。

However from my controller I want to know the original URL the request came from (so I can generate a link if required). This approach is needed generically across all pages so it is difficult to hard code.

的我如何可以访问我的控制器原始路径+查询字符串？的

我已经使用$ 0包含完整的路径尝试，但不包括查询字符串。我不能只追加路径，因为这会导致路径的一些部分被添加作为参数 /分类/ CAT1类= CAT1和放大器的查询字符串; Q = X 注意增加不必要的＆放大器;类别= CAT1 参数，这将导致URL到从浏览器发送不再匹配

I have tried using $0 to include the full path but this doesn't include the query string. I can't just append the path and the query string as this would result in some parts of the path being added as parameters /category/cat1?category=cat1&q=x Note the addition of the unwanted &category=cat1 parameter, this causes the URL to no longer match that sent from the browser.

我希望mod_rewrite的将让我引用的完整URL和连接code将其作为一个参数，所以我的规则可能看起来像：

I'm hoping mod_rewrite will let me reference the full URL and encode it as a parameter so my rule could look like:

RewriteRule /category/(.+)
            /controller?category=$1&_originalUrl=${escape:$0}?${escape:<original query string>}
            [QSA]

使用我原来例如，通过我的控制器通过了最终的结果将是：

Using my original example the end result passed through to my controller would be:

/controller?category=cat1&_originalUrl=%2Fcategory%2Fcat1%3Fsearch%3Dx&search=x

重要的部分是价值＆放大器; _originalUrl 这应该是％2Fcategory％2Fcat1％3Fsearch％3DX 这在其转义的版本是 /分类/ CAT1？q = X （这是从浏览器发送原始请求URL）。

The important part is the value of &_originalUrl which should be %2Fcategory%2Fcat1%3Fsearch%3Dx which in its unescaped version is /category/cat1?q=x (the original request URL that was sent from the browser).

任何建议表示欢迎，在此先感谢！

Any suggestions welcome, thanks in advance!

推荐答案

查询可以ONY与<一个测试href=\"http://httpd.apache.org/docs/2.2/mod/mod%5Frewrite.html#rewritecond\"><$c$c>RewriteCond因为<一个href=\"http://httpd.apache.org/docs/2.2/mod/mod%5Frewrite.html#rewriterule\"><$c$c>RewriteRule确实只测试 URL路径。请参见乔纳森·范伯格的例子的如何做到这一点。

The query can ony be tested with RewriteCond since RewriteRule does only test the URL path. See Jonathan Feinberg’s example how to do that.

但你也可以只设置的 QSA 的标记和旧的查询就会自动附加到新的：

But you could also just set the QSA flag and the old query gets automatically appended to the new one:

RewriteRule ^/category/([^/]+)$ /controller?category=$1 [QSA]

修改在回答这个问题您的评论：如果你想获得初始请求的URI路径和查询，你需要从的请求行（ THE_REQUEST 的变量）：

Edit    In response to your comment to this question: If you want to get the initial requested URI path and query, you need to extract it from the request line (THE_REQUEST variable):

RewriteCond %{THE_REQUEST} ^[A-Z]+\ ([^\s]+)
RewriteRule ^/category/([^/]+)$ /controller?category=$1&_originalUrl=%1 [QSA]

但是在大​​多数语言存在与非常相同的信息的环境变量。

But in most languages there is an environment variable with the very same information.
