File upload not working

[vaIgarashi]

It's not possible to read image from multipart/form-data.

Swagger:

   "/map/background/": {
      "post": {
        "operationId": "createMap",
        "consumes": [
          "multipart/form-data"
        ],
        "parameters": [
          {
            "name": "background",
            "in": "formData",
            "required": true,
            "type": "file"
          },
          {
            "$ref": "#/parameters/Coords"
          }
        ],
      }
    }

Request:

Content-Disposition: form-data; name="coords"

Exception:
java.lang.ClassCastException: java.lang.String cannot be cast to io.vertx.core.json.JsonObject

It's try parse file-uploads/c54807b6-ffa2-44da-be50-6424ab179cad string as File.

Also with current aproach it's not possible to obtain original file name.

[vaIgarashi]

To fix it should be at least like that:

File background = new File(message.body().getString("background"));

instead of:

File background = Json.mapper.readValue(message.body().getJsonObject("background").encode(), File.class);

Small patch to fix this:

Hi.
I have been very busy these past two months. But now, I have time again for the project :)
I will take a look soon.

I downloaded the current v1.6 from maven central and although it seems to contain this fix, code generation still spits out the wrong line for the petstore.json:
File file = Json.mapper.readValue(message.body().getJsonObject("file").encode(), File.class);

My sample code is in a github repo: https://github.com/cburnicki/vertx-file-upload-test
I have no idea why this is still happening.
