我正在将旧式/category.php?id=4url的网站迁移到/ category / seo-friendly-slugurl。
rewrite ^/category.php?id=1$ /styles-de-bieres-belges/pils permanent; rewrite ^/category.php?id=2$ /styles-de-bieres-belges/bieres-blanches permanent; rewrite ^/category.php?id=4$ /styles-de-bieres-belges/lambics-et-gueuzes permanent; rewrite ^/category.php?id=5$ /styles-de-bieres-belges/ales-stouts-et-ipa permanent; rewrite ^/category.php?id=6$ /styles-de-bieres-belges/bieres-trappistes permanent; rewrite ^/category.php?id=7$ /styles-de-bieres-belges/bieres-d-abbaye permanent; rewrite ^/category.php?id=8$ /styles-de-bieres-belges/bieres-rouges-des-flandres permanent; rewrite ^/category.php?id=9$ /styles-de-bieres-belges/lambics-et-gueuzes permanent; rewrite ^/category.php?id=11$ /styles-de-bieres-belges/bieres-fruitees permanent; rewrite ^/category.php$ /styles-de-bieres-belges permanent; 但所有'/category.php?id=...'请求都会redirect到/styles-de-bieres-belges （最后一行）。 如果我删除这最后一行，它根本不redirect。
这个设置有什么问题？
停止使用这些ifs或那些具有类似匹配URI的整个重写。 这将更容易阅读和维护。 这也将避免性能问题，因为重写规则正则expression式是按顺序testing的。
使用地图 ：
map $arg_id $target { "1" "pils"; "2" "bieres-blanches"; "4" "lambics-et-gueuzes"; "5" "ales-stouts-et-ipa"; "6" "bieres-trappistes"; "7" "bieres-d-abbaye"; "8" "bieres-rouges-des-flandres"; "9" "lambics-et-gueuzes"; "11" "bieres-fruitees"; } server { ... location /category { rewrite ^/category.php$ /styles-de-bieres-belges/$target? permanent; } }
查询string被转换为重写规则中的variables，并被删除。 对于你的例子，所有的重写引擎看到的是category.php ，但是存储了$arg_id值。
尝试这样的事情：
location = /category.php { if ($arg_id = "1") {rewrite ^ /styles-de-bieres-belges/pils permanent;} if ($arg_id = "2") {rewrite ^ /styles-de-bieres-belges/bieres-blanches permanent;} ... the rest of them ... if ($arg_id !~ "^\d+$") {rewrite ^ /styles-de-bieres-belges permanent;} }
