Using aria2c, is there a way to make the output filename the same as the input URL in a batch download?

aria2c has an event hook feature that runs a given script when an event occurs. Using the --on-download-complete param for example, is there a way to change the output file's name to its download URL? Now there may be a way to use -o somehow, but I don't think it will effective when handling multiple downloads. Here's an example of what I'd be using as the base command:

aria2c -i <urls> --optimize-concurrent-downloads true

Using the whole URL as a filename

is there a way to change the output file's name to its download URL

No, because file URLs contain the character / which is the only character that cannot be part of a filename in Linux, since it is used a as separator for paths like path/to/dir/.
Windows uses \ as a delimiter, but still forbids to use / inside a filename.

However, you can change the / to something different like |. You can manually specify the output name for each input URL inside your input file like so:

domain.tld/abc/xyz/file1
 out=domain.tld|abc|xyz|file1
something.sth/abc/xyz/file2
 out=something.sth|abc|xyz|file2
...

To generate and use a file like this, use

awk '{print; gsub("/","|"); print " out="$0}' fileOfUrls | aria2c -i-

Using only the filename in the URL as a filename

I thought that aria2c already names the files like they are named in the URL. If that doesn't work, generate an input file accordingly:

sed 's|[^/]*$|&\n out=&|' fileOfUrls | aria2c -i-
