[MRG+1] Add template for a downloader middleware #2755

merged 1 commit into from Jul 31, 2017

@redapple redapple commented May 24, 2017

While testing downloader middleware with media pipeline (for #2753 (comment)), I looked for a sample downloader middleware and found only a spider middleware template.

I personally never remember what methods to implement, nor what they should return, hence the verbose comments in the template.

Related/alternative #2633
