在codeigniter文件夹中添加.htaccess后,localhost将指向www.domains.tld



我刚刚开始使用Codeigniter使用本地服务器(MAMP)开发一个简单的静态网站。最初,我访问主页的本地地址是http://localhost/index.php/home。即使是一个简单的本地主机也会重定向到我的主页。我想从URL中删除"index.php",因此我复制粘贴了我在网上找到的.htaccess代码。代码如下所示:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    ### Canonicalize codeigniter URLs
    # If your default controller is something other than
    # "welcome" you should probably change this
    RewriteRule ^(welcome(/index)?|index(.php)?)/?$ / [L,R=301]
    RewriteRule ^(.*)/index/?$ $1 [L,R=301]
    # Removes trailing slashes (prevents SEO duplicate content issues)
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.+)/$ $1 [L,R=301]
    # Enforce www
    # If you have subdomains, you can add them to 
    # the list using the "|" (OR) regex operator
    #RewriteCond %{HTTP_HOST} !^(www|subdomain) [NC]
    #RewriteRule ^(.*)$ http://www.domain.tld/$1 [L,R=301]
    # Enforce NO www
    RewriteCond %{HTTP_HOST} ^www [NC]
    RewriteRule ^(.*)$ http://localhost/$1 [L,R=301]
    ###
    # Removes access to the system folder by users.
    # Additionally this will allow you to create a System.php controller,
    # previously this would not have been possible.
    # 'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php/$1 [L]
    # Checks to see if the user is attempting to access a valid file,
    # such as an image or css document, if this isn't true it sends the
    # request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
    # Without mod_rewrite, route 404's to the front controller
    ErrorDocument 404 /index.php
</IfModule>

最初,我复制粘贴了代码,根本没有更改它(这对我来说很愚蠢),所以上面代码中的"localhost"最初是"www.domains.tld"。当我在浏览器上运行localhost时,它指向了"www.domains.tld"。我注意到了这个错误,并将其更改为上面的内容,localhost仍然指向"www.domains.htmld"。我删除了.htaccess文件以扭转这种效果,但它仍然做了同样的事情。我还将我的根文件夹更改为localhost,但无论我做什么,localhost都指向"domains.tld"。当我在浏览器的地址栏上键入127.0.0.1时,它会正确地指向我的网站。我花了几个小时来了解这种行为的原因,但没有找到解决方案。

任何帮助都将不胜感激。

谢谢,H.

清除DNS缓存并重新启动浏览器。某些浏览器使用DNS缓存重定向,这样你就可以更快地到达它认为正确的网站。

Firefox对此特别讨厌,所以每次安装时我都会禁用其内部DNS缓存。在about:config中,创建以下两个整数类型设置(注意:您必须创建这些设置,默认情况下它们不存在):

  • network.dnsCacheEntries设置为0
  • network.dnsCacheExpiration设置为0

在Chrome中,您需要在隐私设置下关闭DNS预取。

他们这样做的原因是为了让互联网在普通浏览器面前"看起来"更快。对于开发人员来说,这可能是一个相当大的障碍。
