How to add MIME type to POST request Java?

Question

There is the following code:

public static void uploadUserpick(File file) throws URISyntaxException, ClientProtocolException, IOException {  
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(USERPICK_URL);
    MultipartEntity entity = new MultipartEntity();
    entity.addPart("upload", new FileBody(file));
    httppost.setEntity(entity);
    HttpResponse response = httpclient.execute(httppost); 
}

There is the following problem - back-end code restricts a MIME type of POST request, therefore I need to set MIME type of my image file (File file). How can I set it?

Which version of HttpClient? – Raedwald Jun 19 '13 at 21:47 — Raedwald, Jun 19 '13 at 21:47

You should add a "Content-Type" header to the HttpPost based on the format for your image. For example if your file is a GIF image then you should add the header in the following way:

httppost.addHeader(new BasicHeader ("Content-Type", "image/gif"));

Hope it helps.

EDIT

As mentioned in another answer the addHeader method actually has a more straightforward overload than the one I mentioned originally.

httppost.addHeader("Content-Type", "image/gif");

I found out how to do this here. Just do this:

httppost.addHeader("Content-Type", "application/xml");

You may replace

new FileBody(file)

by

new FileBody(file, "image/jpeg");

See related question and blog post.

In case of spring you can do it like this using MediaType class

@RequestMapping(value = { "/xml/private/secure/store.html"}, 
        method = RequestMethod.POST,
        produces = MediaType.APPLICATION_XML_VALUE) 
@ResponseStatus(value = HttpStatus.OK)
@ResponseBody 
public StoreDTO returnStoreXML(Model model, 
        @RequestParam(value = "id", required = false) String id,
        @RequestParam(value = "name", required = false) String name) {

}
