我需要将旧的博客文件夹重定向到我的新博客文件夹，但保留后标题的名称。
# key is always the same
$key = "mysimplekey";
# text is always the same
$plaintext = "text_to_encrypt";
$iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC);
$iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
$ciphertext = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $plaintext, MCRYPT_MODE_CBC, $iv);
$ciphertext = $iv . $ciphertext;
$ciphertext_base64 = base64_encode($ciphertext);
$ciphertext_url = rawurlencode($ciphertext_base64);
# gives different values for the same key & encryption text:
echo $ciphertext_url;
至$key = 'mysimplekey';
$ciphertext_dec = base64_decode($_REQUEST['u']);
$iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC);
# retrieves the IV, iv_size should be created using mcrypt_get_iv_size()
$iv_dec = substr($ciphertext_dec, 0, $iv_size);
# retrieves the cipher text (everything except the $iv_size in the front)
$ciphertext_dec = substr($ciphertext_dec, $iv_size);
# may remove 00h valued characters from end of plain text
$ciphertext_dec = trim(mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key, $ciphertext_dec, MCRYPT_MODE_CBC, $iv_dec));
我写道：
/oldblog/post-title这一直有效，直到我碰到像/newblog/post-title
我想从此规则中排除RedirectMatch 301 /oldblog/(.*) /newblog/$1
。感谢。
答案 0 :(得分：0)
要排除oldblog / events，您可以使用：
RedirectMatch 301 ^/oldblog/((?!events).*)$ /newblog/$1
