混合 DBM 重写和重定向，如果 URL 不在列表中，如何停止重写

场景：我需要能够重定向某些 URL 并重写其他 URL

现在，经过多次修修补补，我几乎可以让所有东西正常工作

如果我example.com正常上班，200

如果我点击了，example.com/testrea就会example.com/test11/ucm25685.htm显示 200

如果我点击example.com/retest111/totest11.htm重定向，example.com/test1/ucm12347.htm确实会发生这种情况，但是我得到了 403 Forbidden

我如何停止 403 Forbidden？我想我知道为什么会发生这种情况，但无法弄清楚如何停止它。如果我禁用重写部分，重定向将正常工作并且不会显示 403 forbidden。

为什么会发生 403 Forbidden，从日志中可以看出，当请求页面但不在 RewriteMap examplemap (rewrite.dbm) 中时，它会发送/。我以为会是一个缺失的索引，但是添加-Indexes到Options没有任何变化，并且/确实有一个在 vhost 中定义的 index.htm。

问题是，当发出请求时，如果 URL 不在 RewriteMap examplemap (rewrite.dbm) 文件中，我怎样才能不重写？

或者是否有更好的方法来混合重写和重定向，记住这仅适用于生产中的 POC，我将有几百个重写或重定向，并且 dbm 文件将在新页面移动时更新。

日志输出LogLevel alert rewrite:trace3

    RewriteEngine On
    RewriteMap examplemap "dbm:/etc/httpd/conf/rewrite.dbm"
    RewriteRule ^(.*) /${examplemap:$1}
</IfModule>

以及单独的虚拟主机

<VirtualHost *:80>
    DocumentRoot /var/www/sites/me
    ServerName example.com
    DirectoryIndex index.htm
    ErrorDocument 404 /index.php
    Options +FollowSymLinks
    RewriteEngine On
    RewriteOptions Inherit
    RewriteMap redirects dbm=db:/etc/httpd/conf/redirects.db
    RewriteCond ${redirects:$1} !=""
    RewriteRule ^(.*) /${redirects:$1} [redirect=permanent,last]
</VirtualHost>

答案1

我认为触发 403 是因为您的DirectoryIndex文档（即index.htm）不存在。然而，这只是真正的潜在问题的最终结果……您无条件地重写你的返回值示例图 RewriteMap（可能为“空”）。我怀疑如果你example.com/test1/ucm12347.htm直接请求或任何你不存在的 URL，你会看到相同的结果。示例图 RewriteMap。

当在您的示例图 RewriteMap（每个没有重定向)，则最终会重写到/（文档根目录），因为重写映射返回的结果为空。这将触发 mod_dir 为 提供服务DirectoryIndex。如果DirectoryIndex文档不存在，并且Indexes 选项未启用，那么您将收到 403 Forbidden。

你用你的解决了这个问题重定向 RewriteMap通过创建一个状况首先检查 的返回值RewriteMap。您需要对您的示例图 RewriteMap。 例如：

RewriteMap examplemap "dbm:/etc/httpd/conf/rewrite.dbm"
RewriteCond ${examplemap:$1} !=""
RewriteRule ^(.*) /${examplemap:$1} [L]

选择：

RewriteCond ${redirects:$1} !=""
RewriteRule ^(.*) /${redirects:$1} [redirect=permanent,last]

您可以将查找结果存储RewriteMap在环境变量中，以避免多次查找（在状况和RewriteRule 代换）。尽管查找的结果RewriteMap被缓存了，但这可能看不到任何好处。例如：

RewriteRule (.*) - [E=REDIRECT_TO:${redirects:$1}]
RewriteCond %{ENV:REDIRECT_TO} .
RewriteRule ^ /%{ENV:REDIRECT_TO} [redirect=permanent,last]
