Apache rewriterule assistance needed

问题

I am trying to remove query string: ?id= from this URL:

https://example.com/news-and-events/news/?id=/nodle/nodle-io/ledger-integration-update-compatibility-status-236699676dc6

and keep the page loading/working fine

I tried this:

RewriteEngine On

RewriteCond %{QUERY_STRING} ^(.)?id=(.)?$ [NC]

RewriteRule ^(.*)?$ $1%2? [R=301,L]

it seems to strip the ?id= out fine but the page won't load, just 404s.

My issue is making the content load / carry over on the new URL.

https://example.com/news-and-events/news/nodle/nodle-io/ledger-integration-update-compatibility-status-236699676dc6

Any help appreciated,
Thanks

Was expecting URL to load fine and not 404, but with the shorter URL.

更新的答案:

/ 丢失可能是因为您可能尚未声明 RewriteBase。由于您正在使用整个 REQUEST_URI,因此代码中的以下部分应该可以解决这个问题。

此外,RewriteCond 的第二个括号表达式需要一个 * 来提供完整的 QUERY_STRING(通过搜索模式 id=/ 减少)。

文件:/news-and-events/news/.htaccess

RewriteEngine On
RewriteBase "/news-and-events/news/"

RewriteCond %{QUERY_STRING} ^(.)?id=/(.*)?$ [NC]
RewriteRule ^(.*)?$ $1%2? [R=301,L]

简化版本

文件:/news-and-events/news/.htaccess

RewriteBase /news-and-events/news/
RewriteCond "%{QUERY_STRING}" "^id=/(.*)$" [NC]
RewriteRule "(.*)" "$1%1?" [R=301,L]

或者 在您的 virtualhost.conf 文件中:

这里上下文非常重要:

<VirtualHost *:80>

	DocumentRoot "/var/www/vhosts/myhost/htdoc/"
	# 其他指令
	
	# 仅需要一次:
	RewriteEngine On
		
	<Directory "/var/www/vhosts/myhost/htdoc/news-and-events/news/">
		RewriteBase "/news-and-events/news/"
		RewriteCond "%{QUERY_STRING}" "^id=/(.*)$" [NC]
		RewriteRule "(.*)" "$1%1?" [R=301,L]
	</Directory>
	
	# 更多 <Directory> 容器
	
</VirtualHost>

顺便说一下,将模式括在双引号中是一个好习惯,即使不总是必要的。

一些建议

您匹配的是 QUERY_STRING

QUERY_STRING = 'id=/nodle/nodle-io/ledger-integration-update-compatibility-status-236699676dc6'

它始终从 URL 中的 ? 后面的字符开始。
因此,在 RewriteCond 中的匹配并不是必需的。

由于正则表达式是贪婪的,您选择整个字符串,强制使用 ^ 开始和 $ 结束的字符串是多余的。并且通过 ? 使其变为可选是不必要的,因为 (.*) 本身可能为空。

注释

您正在匹配 QUERY_STRING

QUERY_STRING = 'id=/nodle/nodle-io/ledger-integration-update-compatibility-status-236699676dc6'

它始终从 URL 的 ? 后面的字符开始。
因此,在 RewriteCond 中的匹配不生效。

另外,您已经透露,代码将驻留在 Apache 服务器的 virtualhost.conf 文件中。
此外,配置不是独立的,而是 WordPress 安装的子目录,还使用了一些 Rewrite 规则。
因为您已经启用了 .htaccess 的指令,但希望将规则写在 virtualhost.conf 文件中。
使用适当的 <Directory> 容器非常重要,以防止与 WordPress 安装的交叉影响(在两个方向)。

AllowOverride All

首先清理掉可能仍然存在的以前的“实验”.htaccess 文件,以解决您的问题。非常重要!

但显然,您的意图与您提出的问题相反:

因此,除了所提出的解决方案可以实现您的要求外,显然重写后的 URL 上没有内容,您最终会得到一个 404 - 未找到 的 HTML 客户端错误。

这样做的意义在于,当由于服务软件的更改导致 URI 结构发生变化时,您希望访问者能够访问内容。此外,通过 HTML 状态码 301 - 永久移动,搜索引擎将迅速学会使用新的 URI 逻辑并保持 SEO 。

英文:

Updated Answer:

The / is missing because you probably have not declared the RewriteBase. As you are using the whole REQUEST_URI this one below in the code should do it.

Additionally the second bracket expression of the RewriteCond needs an * to provide the full QUERY_STRING (reduced by the search pattern id=/).

File: /news-and-events/news/.htaccess:

RewriteEngine On
RewriteBase &quot;/news-and-events/news/&quot;

RewriteCond %{QUERY_STRING} ^(.)?id=/(.*)?$ [NC]
RewriteRule ^(.*)?$ $1%2? [R=301,L]

Simplyfied Version

File: /news-and-events/news/.htaccess:

RewriteBase /news-and-events/news/
RewriteCond &quot;%{QUERY_STRING}&quot; &quot;^id=/(.*)&quot; [NC]
RewriteRule &quot;(.*)&quot; &quot;$1%1?&quot; [R=301,L]

OR within your virtualhost.conf-file:

Here the context is essential:

&lt;VirtualHost *:80&gt;

	DocumentRoot &quot;/var/www/vhosts/myhost/htdoc/&quot;
	# Other directives
	
	# Only required once:
	RewriteEngine On
		
	&lt;Directory &quot;/var/www/vhosts/myhost/htdoc/news-and-events/news/&quot;&gt;
		RewriteBase &quot;/news-and-events/news/&quot;
		RewriteCond &quot;%{QUERY_STRING}&quot; &quot;^id=/(.*)&quot; [NC]
		RewriteRule &quot;(.*)&quot; &quot;$1%1?&quot; [R=301,L]
	&lt;/Directory&gt;
	
	# More &lt;Directory&gt; container
	
&lt;/VirtualHost&gt;

BTW: It is a good habit to enclose the patterns in double quotes, even if not always necessary.

Some Comments

You match against QUERY_STRING:

QUERY_STRING = &#39;id=/nodle/nodle-io/ledger-integration-update-compatibility-status-236699676dc6&#39;

It will always begin with the character after the ? in the URL.
So the match in the RewriteCond does not

As the regex is greedy and you select the whole string forcing the ^ start and $stop of the string is obsolete. Also making it optional by ? is unnecessary, as (.*) may evaluate to empty by itself.

Notes

  • Meanwhile you've disclosed, that the code shall reside in a virtualhost.conf-file of the apache server.
  • Also the configuration is not standalone but a sub-directory of a WordPress installation, that also uses some Rewrite rules.
    As you have enabled the directive for .htaccess, but want to write the rules in the virtualhost.conf-file.
  • Using the propper <Directory> container is essential to prohibit cross-influences with your WordPress installation (in both directions).
AllowOverride All

you should first cleanup all possibly still existing previous "experiments" within .htaccess files to solve your problem.
— Really important!


But obviously your intent has been the inverse of that what has been your question:

So besides the fact, the presented solution does what you've asked, there is obviously no content at the rewritten URL and you end up with a 404 &#183; Not found. HTML client error.

Doing something like this has its sense, when it comes to a changed URI-structure (i.e. because of a change of the serving software) and you want your visitors to be able to follow the content. Also by the HTML status code 301 &#183; Moved permanently the search engines will quickly learn to use the new URI logic and keep the SEO up.
