問(wèn)題描述

我正在嘗試圍繞 mod 重寫(xiě)，但似乎無(wú)法弄清楚這一點(diǎn).

I'm trying to wrap my head around mod rewrite, but can't seem to figure this out.

有什么辦法可以做到以下幾點(diǎn)嗎?

Is there a way I could do the following?

用戶輸入:http://wildcard.mydomain.com

默默地寫(xiě)信給:

http://mydomain.com/index.php?username=wildcard

推薦答案

您必須在 RewriteCond 然后在 RewriteRule.額外的 RewriteCond 用于防止 www.mydomain.com 和 index.php 被重寫(xiě)

You must capture the first part of the domain in a RewriteCond and then use this in a RewriteRule. The additional RewriteConds are there to prevent www.mydomain.com and index.php being rewritten

RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.
RewriteCond %{REQUEST_URI} !index.php
RewriteCond %{HTTP_HOST} ^(.+?).mydomain.com$
RewriteRule .* /index.php?username=%1 [L]

但這只是所需功能的一小部分.此外，您必須為所有 username.mydomain.com 域名設(shè)置 DNS 條目或設(shè)置 通配符 DNS 條目 *.mydomain.com 指向您的主機(jī).

But this is only a small part of the needed functionality. Additionally, you must setup DNS entries for all of your username.mydomain.com domain names or setup a wildcard DNS entry *.mydomain.com pointing to your host.

否則，例如，客戶端會(huì)嘗試聯(lián)系 jcraine.mydomain.com，但找不到 DNS 條目并進(jìn)行投訴.

Otherwise, the client tries to contact jcraine.mydomain.com, for example, and doesn't find a DNS entry and complains.

如果這是虛擬主機(jī)，您還必須為每個(gè)添加一個(gè) ServerAlias你的用戶名

If this is a virtual host, you must also add a ServerAlias for each of your usernames

ServerAlias jcraine.mydomain.com

或一個(gè)通配符捕獲所有子域

or a wildcard catching all subdomains

ServerAlias *.mydomain.com

這篇關(guān)于Mod使用GET變量將子域重寫(xiě)為PHP的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
