## .htaccess中配置的场景
### 自定义错误页面
在`.htaccess` 中
```
ErrorDocument 404 /404.html
ErrorDocument 500 /500.htm
```
### 限制迅雷
通过特征分析,限制迅雷访问
```
RewriteCond %{HTTP_USER_AGENT} 2.0.50727 [NC,OR] --如果是迅雷在HTTP_USER_AGNET中就有2.0.50727
RewrtieCond %{HTTP_USER_AGENT} ^BlackWido ^BlackWido [NC,OR]
RewriteRule . /demo.txt
```
### 防盗链
不显示图片
```
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://www.demo.com/.*$ [NC]
RewriteRule \.(gif|jpg|png)$ –[F,NC]
```
显示禁止的图片
```
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://www.demo.com/.*$ [NC]
RewriteRule \.(gif|jpg|png)$ localhost/demo/2.jpg [R]
```
### 带post 的参数转发到其他域名
> [参数](https://blog.csdn.net/mengzuchao/article/details/80593789)
可在`.htaccess` 中配置
`RewriteRule ^(Api/User/get_dept_id)$ http://192.168.0.123:82/$1 [L,R=301,P]`
并且加载 `http.conf`的两个模块
```
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
```
### 重定向指定url
开启
`mod_proxy.so`与`mod_proxy_http.so`
```
ProxyPass /imapp/depts http://127.0.0.1:8081/imapp/depts
ProxyPass /api/dept/op_record http://127.0.0.1:8081/api/dept/op_record
```
### URL所有重定向
```
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]
```
//可添加判断,是否开启重写模块
```
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]
```
### 永久 /临时 重定向
301-永久重定向
302-临时重定向
```
Redirect permanent index.php home.php #永久重定向
Redirect temp index.php home.php #临时重定向
```
### 重定向移动设备
```
RewriteEngine On
RewriteCond %{REQUEST_URI} !^/m/.*$
RewriteCond %{HTTP_ACCEPT} "text/vnd.wap.wml|application/vnd.wap.xhtml+xml" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "acs|alav|alca|amoi|audi|aste|avan|benq|bird|blac|blaz|brew|cell|cldc|cmd-" [NC,OR]

```
### 强制浏览器下载指定的文件类型
你可以强制浏览器下载某些类型的文件，而不是读取并打开这些文件，例如MP3、XLS。
```
ForceType application/octet-stream
Header set Content-Disposition attachment
ForceType application/octet-stream
Header set Content-Disposition attachment
```
### 使用.htaccess缓存 给网站提速
调试时谷歌浏览器需要关闭缓存开关
```
# 1 YEAR
Header set Cache-Control "max-age=29030400, public"
# 1 WEEK
Header set Cache-Control "max-age=604800, public"
# 2 DAYS
Header set Cache-Control "max-age=172800, proxy-revalidate"
# 1 MIN
Header set Cache-Control "max-age=60, private, proxy-revalidate"
```
### 404页面跳转，跳转到404.php，根据url记录不存在页面的路径
```
RewriteEngine On
RewriteCond %{REQUEST_METHOD} POST
RewriteCond %{REQUEST_URI} .wp-comments-post\.php*
RewriteCond %{HTTP_REFERER} !.*yourdomainname.* [OR]
RewriteCond %{HTTP_USER_AGENT} ^$
RewriteRule (.*) ^http://%{REMOTE_ADDR}/$ [R=301,L]
```
### 只允许 get,post 请求
apache 2.4版本 中
```
Require all denied
```
