Dear Experts!
I try to get for an entityset all images from my backend system via odata service.
The single get_entity works without problems. I tried to get for a entityset to get the images, but this does not work. I think this is actually not supported. So i have the idea to use a batch functionality to get for selected i materials in my ui5 application the images.
But actually i get the batch request not working.
In the header of my request, i set as content type "image/png;boundary=batch_zmybatch"
My body looks like this.
--batch_zmybatch
Content-Type: image/png
Content-Transfer-Encoding: binary
GET PicturesSet(Matnr='000000000100013301',Type='t')/$value HTTP/1.1
--batch_zmybatch--
My response is http rc 415: The server is refusing to process the request because the entity has an unsupported format
I don´t know exactly what i am doing wrong.
If i use a batch to get an entity for materials:
--batch_zmybatch
Content-Type: application/http
Content-Transfer-Encoding: binary
GET MaterialSet('000000000100012001') HTTP/1.1
--batch_zmybatch--
this works without problems. So i think with the images, i have a problem here.
Does anybody of you have an idea how to get the images by batch?
Regards!
