Loading resource from an URL returns 0 bytes (Redirection?)

Dev Community Dev/API Corner
1

So when I try to load a cover to make the DirectoryObject more appealing it seems 0 bytes are returned.

(Image loads fine in my browser)

 

Code trying to load the image:

@route(PREFIX + '/anime')
def Animelist():
oc = ObjectContainer(title2 = 'All anime')
animes = Masterani().animes()
for anime in animes:
id = anime['id']
name = anime['name']
summary = anime['description']
cover = anime['mal_image']
Log.Info(cover)
oc.add(DirectoryObject(key = Callback(Episodelist, anime_id = id, anime_name = name), title = name, summary = summary, thumb = Resource.ContentsOfURLWithFallback(url = cover, fallback = R(COVER))))
 
if len(oc) < 1:
return ObjectContainer(header = 'Empty', message="Unable to load anime shows!")   
return oc

When using Resource.ContentsOfURLWithFallback, you do not need to use R() in the fallback parameter.

COVER = 'icon-default.jpg'

thumb = Resource.ContentsOfURLWithFallback(url = cover, fallback = COVER)

Thanks but that still doesn't fix the issue why it's returning 0 bytes from the url, the fallback will never be used because it thinks it grabbed the picture but it's actually a 0 bytes picture resulting in displaying nothing.

The 0 bytes log line is from the redirect from the Plex Media Server URL (/:/plugins/com.plexapp.plugins.animehd/resources/contentWithFallback?....etc.) to the real image URL. A redirect http request doesn't contain a body, that's why it's 0 bytes. That is normal behaviour.

I think the issue could be that the redirect goes from http (local PMS) to https. Can you please try and see if it works if you replace https with http in your channel code?

cover = anime['mal_image'].replace('https://', 'http://')

Replacing https with http worked thanks a lot!
