nginx 做本地图片js等静态资源映射，转发请求

1. server_name:监听请求名称
2. root E:\fileServer\uploadFile; 指定本地静态文件路径
3. if (!-f $request_filename) 判断请求的文件是否不存在，不存在则转发请求到。
   备注$1、$2…”等变量为请求正则中第几个参数，如：
   location ~* /(.*)/(\d+)(\d+)(\d+)x(\d+)_([0-9a-xA-X]+).(jpg|png|jpeg|gif)$ {
4. proxy_store 存为缓存，加快访问速度。proxy_store_access 加上文件的读写权限
5. 转发请求：proxy_pass “http://localhost:8080/imgService/thumbnailImgNginx?itemImg=$filepath&width=$width&height=$height&editType=center”;

具体server{}配置：

server {
        listen       80;
        server_name  img.beidouxh.com;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
	   proxy_pass http://img.beidouxh.com:8080/imgService/test;
        }

	

	location ~* /(.*)\/(\d+)_(\d+)_(\d+)x(\d+)_([0-9a-xA-X]+)\.(jpg|png|jpeg|gif)$ {
		set $filepath "/$1/$2_$3.$7";
		set $filename "$2_$3.$7";
		set $thumb    "$2_$3_$4x$5_$6.$7";
		set $width    $4;
		set $height   $5;
		set $editType $7;

		root   E:\fileServer\uploadFile;
		
		if (!-f $request_filename) {
			proxy_pass http://localhost:8080/imgService/thumbnailImgNginx?itemImg=$filepath&width=$width&height=$height&editType=center;
			break;
		}	
        proxy_store          $document_root/$1/$thumb;
      proxy_store_access   user:rw  group:rw  all:r;
     proxy_set_header     Host $host;
        }

	location ~* \.(jpg|png|jpeg|gif)$ {

	     root   E:\fileServer\uploadFile; 
	}
