Shopware 6 | API | Uploading media (JPEG file) with Java OKHTTP3 outputs "Unsupported Media Type"

[Sven Auer]

Hello all,

when I try the following I get the error message at the end of this message. I would be very happy if someone finds the error and shares it with me.

Many thanks in advance.
Greetings Sven

Welcome to the Ranch.

The MIME type is called "image/jpeg", not "image/*jpg". Where did you get that?

@Tim Moores Thank you for the welcome and your help. I don't remember where I got the wrong MIME type example.

I have changed the MIME type to "image/jpeg" but now I get a different "Unsupported Media Type" error:

If you are sending image content, you will need to include a Content-Type header:

addHeader("Content-Type", "image/jpeg")

You can remove the Accept header, unless you are expecting image content to be returned.

The Accept header I have removed. and add the following into the Request.Builder()
.addHeader("Content-Type", "image/jpeg")

My code is also:

Request requesImageUpload= new Request.Builder()
        .url(image_upload_url)
        .addHeader("Authorization", "Bearer " + saGetApiToken())
        .addHeader("Content-Type", "image/jpeg")
        //.addHeader("Accept", "image/jpeg")
        .post(requestBody)
        .build();

I get also the following error:

I hope you or someone else has another idea why it don't work.

[Ron McLeod]

I know nothing about Shopware so I don't think I can help much more.

Try consulting the API document/schema to determine what the backend is actually wanting.

[Ron McLeod]

Unlikely that this will resolve the problem, but maybe the message Unsupported Media Type - All provided media types are unsupported is meant to tell you that the type of content you will accept is not supported?

Try adding-back the Accept header, but with a wildcard MIME type:

addHeader("Accept", "*/*")

After add of addHeader("Accept", "*/*") I get a the following different error:

// "Internal Server Error/expected content-lenght did not match actual size"
{
    "errors": [
        {
            "status": "500",
            "code": "CONTENT__MEDIA_UPLOAD",
            "title": "Internal Server Error",
            "detail": "expected content-length did not match actual size",
            "meta": {
                "parameters": {
                    "message": "expected content-length did not match actual size"
                }
            }
        }
    ]
}

If I use the following curl command it works (it doesn't work with okhttp3) - what is wrong:

// The actual media-id is: 1564b5d15ca2454daa96409a3477739b
curl -H "Content-Type: image/jpeg" -H "Authorization: Bearer ...tolen..." -request POST --data-binary "@./product1.jpg" "http://shopware.none/api/_action/media/1564b5d15ca2454daa96409a3477739b/upload?extension=jpg&fileName=product1"

What is the code equivalent in okhttp3 for the above curl example?
