Process media resources as multipart/form-data in OData v4 as sent by sap.ui.unified.FileUploader

[gregorwolf]

Hello UI5 Experts,

in addition to the issue #20 there is also a problem when using the OData v4 endpoint from an SAPUI5 UI. The control sap.ui.unified.FileUploader uses a HTTP POST and multipart/form-data to upload the file. To switch to the required PUT operation as described here I've used the a CustomFileUploader from Arindam Seth. But also this one uses multipart/form-data. As CAP and UI5 are both created by SAP I would expect that both work together smoothly.

You can replicate the issue by using my example project that can be found at:

https://github.com/gregorwolf/cap-community/tree/master/examples/media-handling

you can get it running by using:

npm run build
npm run deploy
npm run start

Now open http://localhost:4004/ and try to upload a png file. I.e. the one from the srv/tests folder of the project.

After the upload the picture should be displayed in the list below the field. But you will only see a GUID. That is caused due to to fact that simply all body data is stored without parsing. When you run the tests in srv/tests/media.http with the VS Code REST Client you will see the uploaded picture.

Best regards
Gregor

Where you able to share something at UI5con Belgium regarding this topic?

[vobu]

yes, I did - and finally got around cleaning it up some: https://github.com/vobu/ui5-cap
will also replace the (your) custom Upload control soon w/ a more streamlined one - and probably also move controls to web components where applicable

[gregorwolf]

Great. Have you tried it also for OData V2?

In the case that you didn't check it in the meantime by yourself @gregorwolf. Yes, it does also work with V2
