Using @Rest In Android Annotations to Make Multipart Post

Question

I am sending a multipart request to a server which will include an image, as well as a couple of strings. I haven't found any guide on how to get this done, all i have found are just how to make post and get and put etc, but nothing on multipart. I would be glad for any help, thanks

Answer 1

Here you have a example to do declare it using a @Rest interface and here you have a example to do it using Spring Android (used by AA to generate the client class)

All together you can use something like this (this code is not tested):

@Rest(rootUrl = "http://mycompany.com/images", converters = FormHttpMessageConverter.class)
public interface RestClient {
    @Post("/loadimage")
    void sendImage(MultiValueMap formfields);
}

@EActivity
public class MyActivity extends Activity {

    @RestService
    RestClient restClient; //Inject it

    void sendImage(InputStream in) {
        MultiValueMap values = new org.springframework.util.LinkedMultiValueMap<String,Object>();

        try {
            values.put("fileName", "a.jpg");
            values.put("file", in);
            restClient.sendImage(values);
        } finally {
            in.close();
        }
    }
}
