我通过PrestaShop.htaccess文件生成器生成了.htacccess文件。有些规则不能正常工作。
这是生成的.htaccess文件：

# Catch 404 errors
ErrorDocument 404 /404.php
例如，这个重写规则不起作用
RewriteRule ^contact-us$ /contact-form.php [QSA,L]
这很好用：
RewriteRule ^my-account$ /my-account.php [QSA,L]
这是在我尝试输入页面后生成的重写日志：mysite.dev.com/联系我们和mysite.def.com/my account：

RewriteRule ^contact-us$ /contact-form.php [QSA,L]不工作的原因：
strip per-dir prefix: /srv/www/mysite/contact-us -> contact-us
applying pattern '.*' to uri 'contact-us'
pass through /srv/www/mysite/contact-us
它匹配一个(.*)并在不重写的情况下通过，由于/contact-us不存在，它触发了404。此规则导致传递：
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
RewriteRule ^my-account$ /my-account.php [QSA,L]工作的原因：
strip per-dir prefix: /srv/www/mysite/my-account.php -> my-account.php
applying pattern '^api/?(.*)$' to uri 'my-account.php'
strip per-dir prefix: /srv/www/mysite/my-account.php -> my-account.php
applying pattern '.*' to uri 'my-account.php'
pass through /srv/www/mysite/my-account.php
嗯。。。它不起作用。这条规则永远不会被应用。与/contact-us的请求完全相同，只是您会注意到，当您请求/my-account时，实际通过重写引擎（作为SUBREQUEST）的是/my-account.php。php扩展甚至在到达重写引擎之前就被添加到了末尾，作为SUB REQUEST。
这让我觉得你在某个地方打开了Multiviews，这使得所有的请求都是有效的，你所需要做的就是在末尾添加一个.php扩展，因为RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]规则会立即通过它。但是，当然，任何像contact-us这样需要重写（到contact-form.php）的请求都是失败的，因为像Multiview这样的东西不会触及它
我不知道为什么你有HTTP authotification头，但它使你的所有请求都能在没有任何重写的情况下通过。您可以尝试删除它（至少出于测试目的）并关闭htaccess文件顶部的多视图：
Options -Multiviews
看看你的规则是否有效。
