Not Acceptable Response" in HTTP?

In my Ruby on Rails application I tried to upload an image through the POSTMAN REST client in Base64 format. When I POST the image I am getting a 406 Not Acceptable Response. When I checked my database, the image was there and was successfully saved.

What is the reason for this error, is there anything I need to specify in my header?

My request:

URL --- http://localhost:3000/exercises.json

Header:

Content-Type  -  application/json

Raw data:

{
    "exercise": {
        "subbodypart_ids": [
            "1",
            "2"
        ],
        "name": "Exercise14"
    },
    "image_file_name": "Pressurebar Above.jpg",
    "image":"******base64 Format*******"
}

Your operation did not fail.

Your backend service is saying that the response type it is returning is not provided in the Accept HTTP header in your Client request.

Ref: http://en.wikipedia.org/wiki/List_of_HTTP_header_fields

Find out the response (content type) returned by Service.

Provide this (content type) in your request Accept header.

http://en.wikipedia.org/wiki/HTTP_status_code -> 406

406 Not Acceptable The resource identified by the request is only capable of generating response entities which have content characteristics not acceptable according to the accept headers sent in the request.

406 happens when the server cannot respond with the accept-header specified in the request. In your case it seems application/json for the response may not be acceptable to the server.

You mentioned you're using Ruby on Rails as a backend. You didn't post the code for the relevant method, but my guess is that it looks something like this:

def create
  post = Post.create params[:post]
  respond_to do |format|
    format.json { render :json => post }
  end
end

Change it to:

def create
  post = Post.create params[:post])
  render :json => post
end

And it will solve your problem. It worked for me :)
