mod_rewrite后不工作[R：重定向]出

Question

我使用CodeIgniter，并试图重写URL友好的SEO。 的目的是......

http://localhost/FOR-SEO/item/view/id 
-> to -> http://localhost/item/view/id 

（只是想离开，SEO出）

我尝试添加的htaccess如下，

RewriteRule ^(.*)/item/view/(.*)$ /item/view/$2 [R,L] 

所以它成为...

RewriteEngine on 
RewriteCond $1 !^(index\.php|resources|robots\.txt) 
RewriteRule ^(.*)/item/view/(.*)$ /item/view/$2 [R,L] 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteRule ^(.*)$ index.php/$1 [L,QSA] 

它工作正常，但在我拿[R]它显示404错误未找到。

我试图检查重写日志，但一切是一样的对于用[R]，没有[R]

这里的日志，[R]（工作）

[rid#1009868a0/initial] (1) [perdir /Applications/MAMP/htdocs/himaparn/] escaping http://localhost:8888/item/view/2 for redirect 
[rid#1009868a0/initial] (1) [perdir /Applications/MAMP/htdocs/himaparn/] redirect to http://localhost:8888/item/view/2 [REDIRECT/302] 
[rid#10098a8a0/initial] (1) [perdir /Applications/MAMP/htdocs/himaparn/] internal redirect with /index.php/item/view/2 [INTERNAL REDIRECT]

[rid#1009978a0/subreq] (1) [perdir /Applications/MAMP/htdocs/himaparn/] internal redirect with /index.php/item/view/2 [INTERNAL REDIRECT] 

这里是没有[R]的日志，（不工作）

[localhost/sid#100813108][rid#10098f8a0/initial] (1) [perdir /Applications/MAMP/htdocs/himaparn/] internal redirect with /item/view/2 [INTERNAL REDIRECT] 
[localhost/sid#100813108][rid#100993a50/initial/redir#1] (1) [perdir /Applications/MAMP/htdocs/himaparn/] internal redirect with /index.php/item/view/2 [INTERNAL REDIRECT]

这是什么错误，我有什么不对的做法，使我的工作？

非常感谢！

Answer 1

我认为这是因为[R]forces an external redirect在这种情况下，基地已经设置和路径被附加到重定向端点的基地址。

所以，用[R]，以http://example.com/index.php/item/view/2的请求，/index.php/item/view/2将被追加到http://example.com/离开你http://example.com/index.php/item/view/2

没有[R]您得到的内部重定向。这将附加/index.php/item/view/2到请求。因此请求http://example.com/index.php/item/view/2将使您与http://example.com/index.php/item/view/2/index.php/item/view/2挂钩你一个404。

你可以很清楚地看到日志中多次重定向：

[摆脱＃100993a50 /开始/ REDIR＃1] ...
[摆脱＃100991828 /开始/ redir＃2] ...
