nginx root alias difference

访问的目录结构

<code>root@nginx02  ~
<span># tree /application/image/</span>
/application/image/
|<span>-- 01.jpg</span>
|<span>-- images</span>
|   |<span>-- 01.jpg</span>
|   |<span>-- i1</span>
|   |   `<span>-- 01.jpg</span>
|   |<span>-- i2</span>
|   |   `<span>-- 02.jpg</span>
|   |<span>-- i3</span>
|   |   `<span>-- 03.jpg</span>
|   |<span>-- i4</span>
|   |   `<span>-- 04.jpg</span>
|   |<span>-- i5</span>
|   |   `<span>-- 05.jpg</span>
|   |<span>-- i6</span>
|   |   `<span>-- 06.jpg</span>
|   `<span>-- i7</span>
|       `<span>-- 07.jpg</span>
`<span>-- imgs</span>
    `<span>-- 01.jpg</span><span>9</span><span>directories</span>, <span>10</span><span>files</span></code>

栗子说明

<code><span>1</span>，如果请求路径是完全匹配^<span>$正</span>则 <span>alias</span> 必须是完整的路径匹配 不然会找不到文件
  http:<span>//www.static.com/images/i1/01.jpg</span>
  location ~ <span>"^/images/i([0-9]{1})/(.*\.(gif|jpg|png|js|css))$"</span> {
     <span>alias</span> /application/<span>image</span>/images/i<span>$1</span>/<span>$2</span>;
  }

 <span>2</span>，如果请求路径是目录请求 <span>alias</span> 路径别名最后/必须加上
  http:<span>//www.static.com/test/01.jpg</span>
  http:<span>//www.static.com/test/i1/01.jpg</span>
  location /test/ {
     <span>alias</span> /application/<span>image</span>/images/;
  }
 <span>3</span>，如果请求路径是/test/<span>01.</span>jpg 返回的路径<span>alias</span> /application/<span>image</span>/images/<span>01.</span>jpg
 <span>4</span>，如果请求路径是/test/i1/<span>01.</span>jpg 返回的路径<span>alias</span> /application/<span>image</span>/images/i1/<span>01.</span>jpg
 注意-----------
 <span>alias</span> 会自动把请求/test/i1/<span>01.</span>jpg i1自动拼接到 <span>alias</span> /application/<span>image</span>/images/i1/后面 在去查找文件


 /i1/<span>01.</span>jpg
 如果请求www.test/il/<span>01.</span>jpg root 会把i1拼接到 root /application/<span>image</span>/images/il/ 到i1目录找<span>01.</span>jpg
 若果是请求/i1/i01/<span>01.</span>jpg 会把i1/i01拼接到 root /application/<span>image</span>/images/il/i01/ 到i1/i01目录找<span>01.</span>jpg
 root 路径最后面可以没有/;
 location /i1/ {
     root /application/<span>image</span>/images;
 }

总结 
  <span>1</span>,root  使用 /i1/ 是拿i1/后面去拼接 ，root 路径后面可以没有反斜杠/
  <span>2</span>,<span>alias</span> /test/i1/ 是从/test/后面拿去拼接，就是二级目录去拼接 访问目录必须带反斜杠 ，如果完全资源匹配就不用加上反斜杠/;
