Hello, I am trying to upload files to Nginx and process them via itself. I have compiled it with nginx\_upload\_module-2.2.0. My config is the following: server { listen 80; server\_name [example.com](http://example.com); client\_max\_body\_size 100m; ``` location / { root /www; autoindex on; } location /upload { root /www; if ($request_method = POST) { upload_pass @test; break; } upload_store /www/upload; upload_store_access user:rw group:rw all:rw; 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”; upload\_aggregate\_form\_field “$upload\_field\_name.md5” “$upload\_file\_md5”; upload\_aggregate\_form\_field “$upload\_field\_name.size” “$upload\_file\_size”; upload\_pass\_form\_field “^submit$|^description$”; upload\_cleanup 400 404 499 500-505; } location @test { proxy\_pass [http://example.com:8080](http://example.com:8080); } } ``` server { listen 8080; server_name example.com; location / { root /www; } ``` } This works, but it saves my uploads with random number names like 0000000001 0000000002 0000000003 0000000004 0000000005 0000000006 0000000007 0045422062 0059512315. I want to save them with the original name. Remember, my @test backend is also Nginx and not something else. Pls help.

I’m not sure you can really do what you want to. The upload module was not designed for this purpose. If you want to do this you either need to modify the source of the upload module or perhaps you can handle such logic by using the lua module to script what to do with the file uploads.

This seems odd. If it wasn’t meant for Nginx to process uploaded files, then it couldn’t have processed them by itself. For example, I changed location @test { proxy\_pass [http://example.com:8080](http://example.com:8080); to location @test { default\_type text/html; root /www; and removed the :8080 server part and it still works. So I am inclined to think that there must be a way to set the filename without going to such lenghts as to change the code.

Yes there is, but the default nginx install does not have the features available to do what you want and the upload module does not introduce any such feature either. If you want nginx to be able to rename files based on user input then you need a module which introduces that capability into nginx. Of course, at this point I’m talking theory only as I haven’t ever done anything like this, but it should work provided either lua module or perl module has the adds the required features - in theory.

You should do this task in your application and it’s not odd (see below why).

You also need to validate its content. Otherwise, you will open a potential security hole in your server. wbr, Valentin V. Bartenev ---

There’s a lua-resty-upload library for ngx\_lua that can do non-buffered uploading: ``` https://github.com/agentzh/lua-resty-upload ``` You don’t have to touch the disk at all if you prefer sending the data chunks to the TCP/UDP backends (via cosockets) in a strict non-buffered mode.
