nginx-upload模块介绍
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/NginxHttpUploadProgressModulenginx-upload-module下载地址及相关说明：http://www.grid.net.ru/nginx/upload.en.html
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" $upload_tmp_path;
# Inform backend about hash and> upload_aggregate_form_field "${upload_field_name}_md5" $upload_file_md5;
upload_aggregate_form_field "${upload_field_name}_size" $upload_file_size;
upload_pass /test ;
upload_pass_args on;
upload_limit_rate 128k;
upload_store /data/html/www/source/image/sourceImage;
upload_store_access user:r;
upload_pass_form_field "^.*$";
upload_cleanup 400 404 499 500-505;
}
location /test {
proxy_pass http://localhost:10000/image/upload;
}
# Pass> location ~ .*\.php {
#fastcgi_passunix:/tmp/php-cgi.sock;
fastcgi_pass127.0.0.1:9000;
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$";意思是把submit，description这两个字段也原样通过upload_pass传递到后端处理。如果希望把所有的表单字段都传给后端可以用upload_pass_form_field "^.*$";
