htaccess/mod_write规则优化：补全/app/login重写规则需求

需要实现的URL重写映射：

/app/12345/process/789 => /app/process.php?contract_id=12345&id=789
/app/12345/login =>       /app/login.php?contract_id=12345
/app/12345/settings =>    /app/settings.php?contract_id=12345
/app/12345/tags =>        /app/tags.php?contract_id=12345
/app/12345 =>             /app/start.php?contract_id=12345
/app/login =>             /app/login.php

已完成的重写规则：

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^app/([^/]+)/process/([^/]+)/?$         app/process.php?contract_id=$1&id=$2 [L,NC,QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^app/([^/]+)/(login|settings|tags)/?$       verfahrensverzeichnis/$2.php?contract_id=$1 [L,NC,QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^app/([^/]+)/?$                         app/start.php?contract_id=$1 [L,NC,QSA]

补充最后一条规则 #

需要把/app/login重写到/app/login.php的规则放在所有规则最前面，否则会被第二条规则错误拦截，将login识别为contract_id。补充后的完整规则如下：

# 补充的/app/login重写规则
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^app/login/?$ app/login.php [L,NC,QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^app/([^/]+)/process/([^/]+)/?$         app/process.php?contract_id=$1&id=$2 [L,NC,QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^app/([^/]+)/(login|settings|tags)/?$       verfahrensverzeichnis/$2.php?contract_id=$1 [L,NC,QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^app/([^/]+)/?$                         app/start.php?contract_id=$1 [L,NC,QSA]

规则说明

• ^app/login/?$：匹配/app/login和带末尾斜杠的/app/login/两种格式
• [L,NC,QSA]：L表示匹配后终止后续规则解析；NC表示忽略URL大小写；QSA表示保留原URL携带的查询参数
