nginx之線上CDN的rewrite規則修改

jpg 瀏覽器 這樣的 oot image con 轉譯 a-z 依次

線上的CDN廠商的nginx的rewrite規則配置驗證

驗證測試:
為使nginx vhost虛擬主機配置文件更簡潔,所以采用include方式,把nginx的rewrite規則寫到一個單獨的配置文件中

[root@test01 vhost]# grep include /usr/local/nginx/conf/vhost/img.test.conf 
   include /data/www/images/.htaccess; 

下面的rewrite規則是雲端CDN的提供的配置規則,但是其中2條規則存在問題

[root@test01 03]# cat /data/www/images/.htaccess
rewrite ^/[a-zA-Z0-9]+/([0-9][0-9])([0-9][0-9])/([0-9]+).gjf$ /uploads/picture/2016/$1/$2/$3.gif last;
rewrite ^/[a-zA-Z0-9]+/([0-9][0-9])([0-9][0-9])/([0-9]+)(png|jpeg|jpg|gif)$ /uploads/picture/2016/$1/$2/$3.$4 last;
rewrite "^/.{6}[0-9]+/([0-9]{2})([0-9]{2})/(.*)$" /uploads/picture/2016/$1/$2/$3 ;
rewrite "^/.{6}[0-9]{4}/(.*)$" /uploads/picture/2016/$1 last;
rewrite "^/.{6}[0-9]{4}[0-9]{8}/(.*)$" /uploads/picture/$1 last; (此規則雲端CDN配置有問題,位置應該放到第一的位置就可以了)
rewrite ^/[0-9]+\.([0-9]+)\.([0-9]+)\.([0-9]+)\.(.*)$ /uploads/picture/$1/$2/$3/$4 last; (此規則雲端CDN配置有問題,點號不需要轉譯的)
rewrite ^/[0-9]+/([0-9][0-9])([0-9][0-9])/(.*)$ /uploads/picture/2016/$1/$2/$3 last;

本人親自測試成功的文件:

[root@test01 ~]# cat  /data/www/images/.htaccess 
##rewrite ^/[a-zA-Z0-9]+/(.*)$ /uploads/picture/$1 last;
rewrite "^/.{6}[0-9]{4}[0-9]{8}/(.*)$" /uploads/picture/$1 last;
rewrite ^/[a-zA-Z0-9]+/([0-9][0-9])([0-9][0-9])/([0-9]+).gjf$ /uploads/picture/2016/$1/$2/$3.gif last;
rewrite ^/[a-zA-Z0-9]+/([0-9][0-9])([0-9][0-9])/([0-9]+)(png|jpeg|jpg|gif)$ /uploads/picture/2016/$1/$2/$3.$4 last;
rewrite "^/.{6}[0-9]+/([0-9]{2})([0-9]{2})/(.*)$" /uploads/picture/2016/$1/$2/$3 ;
rewrite "^/.{6}[0-9]{4}/(.*)$" /uploads/picture/2016/$1 last;
##rewrite "^/.{6}[0-9]{4}[0-9]{8}/(.*)$" /uploads/picture/$1 last;
rewrite ^/[a-zA-Z0-9]+.([0-9]+).([0-9]+).([0-9]+).(.*)$ /uploads/picture/$1/$2/$3/$4 last;
rewrite ^/[0-9]+/([0-9][0-9])([0-9][0-9])/(.*)$ /uploads/picture/2016/$1/$2/$3 last;

nginx rewrite規則驗證演示:
規則1

rewrite ^/[a-zA-Z0-9]+/([0-9][0-9])([0-9][0-9])/([0-9]+).gjf$ /uploads/picture/2016/$1/$2/$3.gif last;

說明:

/[a-zA-Z0-9]+/:匹配到任意的字符串;
$1指的是第一個圓括號([0-9][0-9]) 中的2位數;
$2指的是第二個圓括號([0-9][0-9]) 中的2位數;
$3指的是第三個圓括號([0-9]+)中的任意數字;([0-9]+).gjf:匹配到以gjf結尾的文件跳轉到請求服務器上的([0-9]+).gif文件【註意:服務器上的([0-9]+).gif這個圖片文件是必須存在的】

實例演示
正常的瀏覽器訪問:

http://img.test.com/uploads/picture/2016/08/03/1501742944.gif
http://img.test.com/uploads/picture/2016/08/03/1501742944.gif?base6412345
http://img.test.com/uploads/picture/2016/08/03/1501742944.gif???dwer

通過匹配到rewrite規則 瀏覽器訪問:

http://img.test.com/awe21/0803/1501742944.gjf
http://img.test.com/22KDJH21/0803/1501742944.gjf??base64

服務器上文件的位置:

[root@test01 03]# ll /data/www/images/uploads/picture/2016/08/03/1501742944.gif
-rw-r--r--. 1 root root 184440 Aug  3  2017 /data/www/images/uploads/picture/2016/08/03/1501742944.gif

規則2:

rewrite ^/[a-zA-Z0-9]+/([0-9][0-9])([0-9][0-9])/([0-9]+)(png|jpeg|jpg|gif)$ /uploads/picture/2016/$1/$2/$3.$4 last;

說明:

/[a-zA-Z0-9]+/:匹配到任意的字符串;
$1指的是第一個圓括號([0-9][0-9]) 中的2位數;
$2指的是第二個圓括號([0-9][0-9]) 中的2位數;
$3指的是第三個圓括號([0-9]+)中的任意數字【註意:這些數字必須是服務器上存在的並且以png|jpeg|jpg|gif結尾文件的前面的數字】;
$4指的是第四個括號(png|jpeg|jpg|gif)中的服務器上必須存在的以png|jpeg|jpg|gif結尾的文件

http://img.test.com/chkDHK123654/0728/1469696883jpeg?2345

規則3:

rewrite "^/.{6}[0-9]+/([0-9]{2})([0-9]{2})/(.*)$" /uploads/picture/2016/$1/$2/$3 ;

說明:

^/.{6}[0-9]+/:匹配到任意6個字符串加任意數字;
$1指的是第一個圓括號([0-9]{2}) 中的2位數;
$2指的是第二個圓括號([0-9]{2}) 中的2位數;
$3指的是第三個圓括號(.*)中的任意字符串。當然$1,$2,$3這些字符串必須是服務器上實實在在存在的字符串,只有這樣在瀏覽器請求時,才能獲取到服務器上的圖片

實例演示:

http://img.test.com/cHrtwK4/0728/1469696883.jpeg??base64

規則4:

rewrite "^/.{6}[0-9]{4}/(.*)$" /uploads/picture/2016/$1 last;

說明:

^/.{6}[0-9]{4}:匹配到任意6個字符串加任意4個數字

實例演示:


http://img.test.com/uploads/picture/2016/07/28/1469696883.jpeg
http://img.test.com/cHrtwK4123/07/28/1469696883.jpeg
http://img.test.com/cH23wK4155/07/28/1469696883.jpeg

以下這樣的是不符合規則的,所以找不到文件

http://img.test.com/cH23wK41/07/28/1469696883.jpeg

規則5:

rewrite "^/.{6}[0-9]{4}[0-9]{8}/(.*)$" /uploads/picture/$1 last;

說明:

^/.{6}[0-9]{4}[0-9]{8} :匹配到任意6個字符串加任意4個數字再加8個任意的數字

實例演示:

http://img.test.com/uploads/picture/2016/07/28/1469696883.jpeg

經測試,此rewrite規則放到此位置,是匹配不到圖片的,所以位置得變動下,把此規則放到規則的首位就可以了

http://img.test.com/weijdg444433336666/2016/07/28/1469696883.jpeg

規則6:

rewrite ^/[a-zA-Z0-9]+.([0-9]+).([0-9]+).([0-9]+).(.*)$ /uploads/picture/$1/$2/$3/$4 last;

註意:此處的點號是不需要轉譯的,轉譯會導致rewrite規則不可用,就如下面的這條rewrite規則是不正確的

rewrite ^/[0-9]+\.([0-9]+)\.([0-9]+)\.([0-9]+)\.(.*)$ /uploads/picture/$1/$2/$3/$4 last;

實例演示:

http://img.test.com/SHDw.2018.08.18/1489719802.png?base641234

規則7:

rewrite ^/[0-9]+/([0-9][0-9])([0-9][0-9])/(.*)$ /uploads/picture/2016/$1/$2/$3 last;

實例演示:

總結:
Apache和nginx的rewrite規則的匹配是有順序的,而且是從上往下依次匹配的。如果上面優先被匹配到就不再匹配下面的規則。
