最近把一個項目從nginx轉移到apache下面,有些rewrite規則?問號後面還有請求參數,apache rewrite規則需要改變一下才能適應這種需求。
我們Rewrite後的地址 /sj/php?page=8, 實際地址 /search-job.php?key=php&page=8
在apache rewrite文檔裏面有一段介紹[QSA]參數,專門用來傳遞?後的請求參數到實際地址。
http://httpd.apache.org/docs/current/rewrite/flags.html#flag_qsa
When the replacement URI contains a query string, the default behavior of RewriteRule
is to discard the existing query string, and replace it with the newly generated one. Using the [QSA] flag causes the query strings to be combined.
Consider the following rule:
RewriteRule /pages/(.+) /page.php?page=$1 [QSA]
With the [QSA] flag, a request for /pages/123?one=two
will be mapped to /page.php?page=123&one=two
. Without the [QSA] flag, that same request will be mapped to/page.php?page=123
- that is, the existing query string will be discarded.
我們由此可以知道我們的規則應該這樣寫:
RewriteRule /sj/(.+) /search-job.php?key=$1 [QSA]
apache的Rewrite規則可以實現很複雜的需求,但由此而來的問題就是它不是完全遵守RegEx正則表達式的規範。
nginx的rewrite很優雅,也比較簡單,雖然它不能實現非常複雜的Rewrite,但應付日常應該足夠。
我個人還是比較喜歡nginx的rewrite的寫法,因爲它是標準的regex正則表達式。
apache Rewrite規則不好調試,因爲它很多時候是不標準的Regex.
