重写规则导致“请求超出 10 个内部重定向的限制”

【问题标题】：Rewrite rule causes 'Request exceeded the limit of 10 internal redirects'重写规则导致“请求超出 10 个内部重定向的限制”
【发布时间】：2014-06-28 02:23:34
【问题描述】：

为什么.htaccess 文件中的上述行导致：

RewriteRule ^([A-Za-z0-9\_\-]+)\/(.*)$ engine/handlers/page_handler.php?handler=$1&page=$2 [QSA,L]

error_log 中的错误如下：

请求超出了 10 次内部重定向的限制，因为可能 配置错误。使用“LimitInternalRecursion”来增加 必要时限制。使用“LogLevel debug”获取回溯。

我在 Stack Overflow 上找到了很多帖子，但没有一个解决方案适合我。我有一个带有 cPanel 的 CentOS 服务器。如果没有 cPanel，这不会在我的服务器上发生。
这是我的 .htaccess 文件：

当我在规则中添加以下内容时，内部重定向停止并且错误消失但 css 和图像不加载：

【问题讨论】：

  • 您能否提供一个触发此规则的示例 URL？另外，您知道是否还有其他.htaccess 规则？
  • 这是一个常见问题。 RewriteRule 非常通用，并且匹配右侧的 URI，从而导致循环。你需要一个RewriteCond 来防止这种情况。通常由 RewriteCond %{REQUEST_FILENAME} !-f 和 RewriteCond %{REQUEST_FILENAME} !-d 完成，以防止将规则应用于真实的现有文件。
  • 如果您想查看，触发此规则的 URL 是 index.php 文件 (companion.gesht.com)。我有这两个RewriteCond 规则。
  • 我添加了整个 .htaccess 文件@anubhava
  • 我用 sub.domain.com 代替了 partner.gesht.com 和 0.0.0.0 代替了我的 IP。

标签： php apache .htaccess


【解决方案1】：

规则重定向到自身。 在您之前尝试以下规则：

RewriteRule ^engine/handlers/page_handler.php  -  [L]

如果服务器为您的 page_handler.php 脚本提供服务，这将结束重定向规则。

【讨论】：

    【解决方案2】：

    你有这两条重写规则

    RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([A-Za-z0-9\_\-]+)$ engine/handlers/... [QSA,L]


RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([A-Za-z0-9\_\-]+)\/(.*)$ engine/handlers/... [QSA,L]
RewriteRule . /~gesht/companion/

    第二条规则的重写格式仍然匹配重写表达式，因此该规则将直接循环回到自身。

    为避免这种情况，要么指定 REQUEST_URI 与 REQUEST_URI 不匹配的 RewriteCond，要么添加环境标志以停止循环：

    ...[QSA,L,E=LOOP:1]

    现在通过对充当停止块的“LOOP”进行环境检查来抢占规则本身；这必须在任何规则设置之前LOOP:

    # if LOOP is set...
RewriteCond %{ENV:LOOP} =1
# ...then no-rewrite and quit.
RewriteRule .* - [L]

# All others rules follow.

    【讨论】：

      【解决方案3】：

      避免这种情况需要做两件事。

      首先要避免无限循环，在RewriteBase 行下方添加此规则

      RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^ - [L]

      然后要注意 css/js/image 不显示，您只需在 css、js、图像文件中使用绝对路径，而不是相对路径。这意味着您必须确保这些文件的路径以 http:// 或斜杠 / 开头。

      否则：

      您可以尝试在页面的 HTML 标头中添加此内容：

      <base href="/" />

      【讨论】：

      • 谢谢 @anubhava 这是一个 elgg 网站，我添加了 &lt;base href="/" /&gt;，但它没有帮助加载 css。我在没有 cPanel 的服务器上和本地机器上都有这个网站，没有任何问题。 cPanel在apache中做了哪些不同的配置会导致这个错误？
      • 文件没有被加载，因为它们像companion.gesht.comcss 而不是companion.gesht.com/css 即使在css和&lt;base href="/"/&gt;之前添加/，问题也没有得到解决。
      • 看起来你有一些错误配置的规则删除了域名后的斜线。
      • 是的，我确实看到在网络 @anubhava 下暂时删除了 302
      • 现在添加斜线后，我会加载 css，但不会加载 js 和图形。当链接正确时，我看到 302 为他们临时移动了消息。
