.htaccess常见规则

htaccess to nginx converter:

https://www.bt.cn/Tools
http://winginx.com/en/htaccess

有绑定多个域名非cloud.cloudduo.cn的话，跳转到cloud.cloudduo.cn

	<IfModule mod_rewrite.c>
		RewriteEngine on
		RewriteCond %{HTTP_HOST} ^cloud.cloudduo.cn [NC]
		RewriteRule ^(.*) http://cloud.cloudduo.cn [L,R=301]
	</IfModule

强制https

#HTTP_TO_HTTPS_START
    <IfModule mod_rewrite.c>
        RewriteEngine on
        RewriteCond %{SERVER_PORT} !^443$
        RewriteRule (.*) https://%{SERVER_NAME}$1 [L,R=301]
    </IfModule>
    #HTTP_TO_HTTPS_END

htaccess.zip

整站转到301到 https://www.cloudduo.cn

#301-START
	<IfModule mod_rewrite.c>
		RewriteEngine on
		RewriteRule ^(.*)$ https://www.cloudduo.cn/ [L,R=301]
	</IfModule>

强制www域名301跳转

我们将域名替换成自己的域名即可实现非WWW跳转到WWW域名。

RewriteEngine on
RewriteCond %{HTTP_HOST} ^niaoyun\.com [NC]
RewriteRule ^(.*)$ http://www.niaoyun.com/$1 [L,R=301,NC]

强制非WWW域名301跳转

这里我们可以强制如果访问www域名前缀，会跳转到非www域名。

RewriteEngine On
RewriteCond %{HTTP_HOST} !^niaoyun.com$ [NC]
RewriteRule ^(.*)$ http://niaoyun.com/$1 [L,R=301]

强制https跳转地址。

RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.nioayun.com/$1 [R=30,L]
如何我们网站采用SSL证书，则一般需要强制跳转https路径，这里需要添加强制80端口的跳转。

强制带WWW跳转和HTTPS强制不带WWW

RewriteEngine On
RewriteCond %{HTTP_HOST} !^cnbanwagong.com$ [NC]
RewriteRule ^(.*)$ https://cnbanwagong.com/$1 [L,R=301]
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://cnbanwagong.com/$1 [L,R=301]
如果我们有朋友喜欢用不带WWW的格式，所以我们也可以强制带WWW跳转和HTTPS强制不带WWW。

阻止无用的蜘蛛爬取。

RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} (^$|FeedDemon|JikeSpider|Indy Library|Alexa Toolbar|AskTbFXTV|AhrefsBot|CrawlDaddy|CoolpadWebkit|Java|Feedly|UniversalFeedParser|ApacheBench|Microsoft URL Control|Swiftbot|ZmEu|oBot|jaunty|Python-urllib|lightDeckReports Bot|YYSpider|DigExt|HttpClient|MJ12bot|heritrix|EasouSpider|Ezooms) [NC]
RewriteRule ^(.*)$ - [F]

强制/斜杠结尾路径。

RewriteCond %{REQUEST_URI} /+[^\.]+$
RewriteRule ^(.+[^/])$ %{REQUEST_URI}/ [R=301,L]

取消/斜杠结尾。

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [R=301,L]

将A页面301跳转到B页面。

Redirect 301 /a.html http://www.niaoyun.com/b.html

阻止某个IP或则某个网段访问。

参考官方教程：https://help.aliyun.com/knowledge_detail/36226.html

Order deny,allow
Allow from all
Deny from xxx.xxx.xxx.xxx
Deny from xxx.xxx.xxx.

禁止图片盗链。

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http(s)?://(.+\.)?niaoyun.com [NC]
RewriteRule \.(jpg|jpeg|png|gif|bmp)$ - [NC,F,L]

禁止被其他网页套用。

SetEnvIf Request_URI "/starry-night" allow_framing=true
Header set X-Frame-Options SAMEORIGIN env=!allow_framing

常用和不常用的.htaccess伪静态、301、防盗链以及等设置功能。如果需要更多强大的htaccess功能则需要阅读官方文档，这10个用途仅仅是很小的部分。
