Question

如果输入类似http://someone.com/hi/hello/yeah的内容，如何重写网址，我希望结果为http://someone.com/?u=hi_hello_yeah

这是我到目前为止所写的，它只替换了没有斜杠的网址“/”

RewriteEngine on
RewriteCond $1 !^(index\.php|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/?u=$1 [L,QSA]

而且，我希望如果用户输入http://someone.com/hi/hello/yeah，它会重定向到http://someone.com/hi_hello_yeah

Answer 1

我认为rewrite规则的最后一行有一个拼写错误。

RewriteRule ^(.*)$ index.php/?u=$1 [L,QSA]

似乎应该更正

RewriteRule ^(.*)$ index.php?u=$1 [L,QSA]

我在帖子中看到两个问题：

您希望获得 斜线到下划线 转换的网址值。
当有人在/hi/hello/year中输入时，网址应 重定向 到/hi_hello_year。

网址重写和重定向是两项独立的操作。

1。斜线到下划线转换

您已拥有$_GET['u']变量，其中包含/hi/hello/year 只需str_replace它就会为您提供转换后的URI字符串。

<?
// this is the landing index.php page specified in the last rewrite rule. 

// should be "/hi/hello/year" for "/hi/hello/year" URL request. 
$rewritten_uri = isset($_GET['u']) ? $_GET['u'] : '';

// converting slashes to underscores.
$converted_uri = str_replace( '/', '_', $rewritten_uri );

// the string begins and/or ends with a slash, so remove it.
$ready_to_use_uri = trim( $converted_uri, '_' );

?>

2。重定向到新URL

输入/hi/hello/year的人应该在他/她的浏览器中看到一个新的/hi_hello_year网址。
这涉及header( "Location: ..." );

<?
$new_url = '/' . $ready_to_use_uri; // which came from the above code
header( 'Location: ' . $new_url );
exit(); // unless you have some more work to do.
?>

3。组合

但是，上面的重定向是基于服务器具有hi_hello_year文档的假设，否则可能会导致无休止的rewrite - redirect循环。让我们结合并添加一个安全措施。

<?
// this is the landing index.php page specified in the last rewrite rule. 

// should be "/hi/hello/year" for "/hi/hello/year" URL request. 
$rewritten_uri = isset($_GET['u']) ? $_GET['u'] : '';

// converting slashes to underscores.
$converted_uri = str_replace( '/', '_', $rewritten_uri );

// the string begins and/or ends with a slash, so remove it.
$ready_to_use_uri = trim( $converted_uri, '_' );

// redirect only when such file exists 
if ( file_exist( $ready_to_use_uri ) )
{
  header( 'Location: /' . $ready_to_use_uri );
  exit(); // unless you have some more work to do.
}

header("HTTP/1.0 404 Not Found");
echo "The document '" . $ready_to_use_uri . "' is not found on this server";
exit();
?>

Answer 2

这很棘手，因为它需要递归应用重写规则。

通过httpd.conf启用mod_rewrite和.htaccess，然后将此代码放在.htaccess目录下的DOCUMENT_ROOT中：

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

# this recursive rule will be applied as many times as the /s in the URI
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/(.+)$ /$1_$2 [L]

# this rule will be applied once all /s have been replaced by _
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/?$ /?u=$1 [L,QSA]

用斜杠重写URL

2 个答案:

1。斜线到下划线转换

2。重定向到新URL

3。组合
