http://192.168.1.233:10000/upload.html

如有裂图 刷新即可(获取的时候 压缩后的图片还没能生成出来)

功能: 图片上传 实现方式:Lua 图片转化:lua+gm

nginx配置:

    server {
        listen       10000;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }


        location ~* /upload/(.*).(gif|jpg|jpeg|png|bmp)$ {
             autoindex on;
              set $orifilename $1;

              set $ori_root '/usr/local/nginx/html/upfile';
              set $targetfilename '${orifilename}.jpg';
              set $thumbnail_root '/usr/local/nginx/html/upfile/thumbnail';
              set $file '${thumbnail_root}/${targetfilename}';

                        if (-f $file) {
                              # rewrite ^/(.*)$ $file last;
                              #  content_by_lua 'ngx.say(true);';
                                content_by_lua 'return  ngx.redirect("/thumbnail/"..ngx.var.targetfilename);';
                        }
                        if (!-f $file) {
                              # rewrite ^/(.*)$ $file last;
                                content_by_lua 'local command="gm convert "..ngx.var.ori_root.."/"..ngx.var.orifilename.."."..ngx.var.imgtype.." -quality 80 +profile *  "..ngx.var.file;

                                               ';

**后续:

1. 实时转换任何请求的图片
2. 通过rest请求给图片转化成不同需求的图片
3. 通过rest请求 转化某个文件夹下的图片**
