Nginx的Upload上传模块 

 

最近了解了一下Nginx的upload module功能蛮强大，记录了下来。
nginx-upload-prgress下载地址：http://wiki.nginx.org/NginxHttpUploadProgressModule

配置Nginx如下，部分如下
server
    {
    listen       80;
    server_name web.test.com;
        index index.html index.htm;
        root /data/html/www;
        if ($host = 'test.com' )
        {

                rewrite ^/(.*)$ http://web.test.com/$1 permanent;  
       
        }
        if (-d $request_filename)
       
        {
   
                rewrite ^/(.*)([^/])$ http://$host/$1$2/ permanent;
   
        }

    # Upload form should be submitted to this location
    location /upload {
          # Set specified fields in request body
            upload_set_form_field "${upload_field_name}_name" $upload_file_name;
            upload_set_form_field "${upload_field_name}_content_type" $upload_content_type;
            upload_set_form_field "${upload_field_name}_path" $upload_tmp_path;

          # Inform backend about hash and size of a file
            upload_aggregate_form_field "${upload_field_name}_md5" $upload_file_md5;
            upload_aggregate_form_field "${upload_field_name}_size" $upload_file_size;

            upload_pass /test ;
            upload_pass_args on;
            upload_limit_rate 128k;
            upload_store /data/html/www/source/p_w_picpath/sourceImage;
   
            upload_store_access user:r;
 
            upload_pass_form_field "^.*$";
            upload_cleanup 400 404 499 500-505;
            }

        
    location /test {
        proxy_pass   http://localhost:10000/p_w_picpath/upload;
        }

       # Pass altered request body to a backend
        location ~ .*\.php {
              #fastcgi_pass  unix:/tmp/php-cgi.sock;
              fastcgi_pass  127.0.0.1:9000;
              fastcgi_index index.php;
              include fcgi.conf;
            }
    }


大概解释一下每个参数 
upload_pass 指明了需要后续处理的地址
upload_cleanup 如果出现400 404 499 500-505之类的错误，则删除上传的文件
upload_store 上传文件存放地址
upload_store_access 上传文件的访问权限，user:r是指用户可读
upload_limit_rate 上传限速，如果设置为0则表示不限制
upload_set_form_field 设定额外的表单字段。这里有几个可用的变量： 
$upload_file_name 文件原始名字 
$upload_field_name 表单的name值 
$upload_content_type 文件的类型 
$upload_tmp_path 文件上传后的地址
upload_aggregate_form_field 额外的变量，在上传成功后生成 
$upload_file_md5 文件的MD5校验值 
$upload_file_size 文件大小
upload_pass_form_field 从表单原样转到后端的参数，可以正则表达式表示官方的例子是upload_pass_form_field "^submit$|^description$";意思是把submit，description这两个字段也原样通过upload_pass传递到后端处理。如果希望把所有的表单字段都传给后端可以用upload_pass_form_field "^.*$";
