Ok, now it works!
It look's like the reason for the error was the url. With a direct link to a file from my appache server I have no problems.
 

&action=upload

&filename=T2.png

&url=http%3A//localhost/t2.png

&ignorewarnings=1

&token=%2B%5C

&format=xml

 

Thanks for helping me!

Betreff: [Mediawiki-api] WG: Image upload fails even with example Request

Now I have set the user rights of group all: now its allowed to every user to upload files and upload from url.
So I can absolutly exclude that cause of defect.
