Hello,

you can try a small config like this:

 location /form {
     echo '<form action="/upload" enctype="multipart/form-data"

method=“post”>’;
echo ‘’;
echo ‘’;
echo ‘’;
}

 location /upload {
     upload_pass /script-to-process;
     upload_store /var/tmp;
     upload_store_access user:r;
     upload_set_form_field $upload_field_name.name

“$upload_file_name”;
upload_set_form_field $upload_field_name.path
“$upload_tmp_path”;
upload_cleanup 400-505;
}

in your process script you get

$_POST[file_path] # this is the file with “something different”
$_POST[file_name] # this is your filename

Cheers,

Alexander

Sorry, yes, echo is no build in option. But you can put this
code into a simple html file. This code shoud only show the
names for the formfields…

The echo directive is provided by the ngx_echo module:

GitHub - openresty/echo-nginx-module: An Nginx module for bringing the power of "echo", "sleep", "time" and more to Nginx's config file

It’s very handy in debugging nginx.conf stuffs :wink:

This is because it’s a temporary file. Saving an uploaded file under the
original name is neither secure nor convenient.

Your script must take care of the permanent name for the file.

It is up to you to implement a script that does this job. Upload module
can save the content of the file fields only into temporary files.

i need to know how to optimize the configuration

mr valery,

is there any module to unzip ,checksum calculation for the uploaded
file?

Experimental version of upload module can unzip files:

Calculating CRC32 is possible with stable version.
