Swagger Dropwizard 0.7 - TextArea for JSON parameter not displayed

885 views Asked by At

The problem

I can't find the reason Swagger doesn't show the POST end point with the textarea 'body' available so I can paste JSON into.

I expected to see a page like this the POST in PetStore Swagger

But my form is simply posted after I click 'Try it out' and I get

Response Body

    <html>
      <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
        <title>Error 415 Unsupported Media Type</title>
      </head>
      <body><h2>HTTP ERROR 415</h2>
        <p>Problem accessing /promotions. Reason:
          <pre>    Unsupported Media Type</pre></p><hr><i><small>Powered by Jetty://</small></i><hr/>
      </body>
    </html>

Response Headers

{
  "access-control-allow-origin": "http://localhost:8080",
  "date": "Thu, 11 Jun 2015 07:37:15 GMT",
  "cache-control": "must-revalidate,no-cache,no-store",

  "content-type": "text/html; charset=ISO-8859-1",
  "content-length": "320",
  "access-control-expose-headers": ""
}

Can you help me with this please?

In the end the annotation @ApiParam did the trick.

New POST method (with the new annotation)

@POST
@Consumes(APPLICATION_JSON)
@ApiOperation(value = "Create promotion", notes = "", response = Promotion.class)
@ApiResponses(value = {
        @ApiResponse(code = 201, message = "Promotion created. Link to it in Location HEADER."),
        @ApiResponse(code = 409, message = "Promotion already exist.")
})
public Response create(@ApiParam final Promotion promotion, @Context final UriInfo uriInfo) throws IOException {
    Promotion createdPromotion = promotionManagementService.create(promotion);

    URI createdPromotionURI = uriTo(createdPromotion, uriInfo);
    return Response.created(createdPromotionURI).build();
}

Thanks for your help cyrbil.

You have @Api as a decorator with consumes = "application/json", and your error is about Unsupported Media Type. So your endpoint expect that you send application/json post data, your browser sends multipart/form-data or url encoded data.
