How To Simulate An Image Attachment HTTP Multipart POST

Below is the code i use for simulating an image attachment using apache http client.

package com.edw.postsimulator;

import java.io.File;
import java.nio.charset.Charset;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.HttpMultipartMode;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.entity.mime.content.StringBody;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.protocol.BasicHttpContext;
import org.apache.http.protocol.HttpContext;
import org.apache.http.util.EntityUtils;

public class PostTest {

    private static String url = "http://localhost:8083/RealsAppApi/images/add";

    public static void main(String[] args) throws Exception {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);
        HttpContext localContext = new BasicHttpContext();
        
        Charset chars = Charset.forName("UTF-8");
        
        // http content
        MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
        entity.addPart("username", new StringBody("edwin", chars));
        entity.addPart("password", new StringBody("edwinpassword", chars));        
        
        // attach image
        File fileToUpload = new File("F:\\no.jpg");
        FileBody fileBody = new FileBody(fileToUpload, "application/octet-stream");
        entity.addPart("image", fileBody);
        httpPost.setEntity(entity);

        // fire and log the responses
        HttpResponse response = httpclient.execute(httpPost, localContext); 
        HttpEntity resEntity = response.getEntity();
        System.out.println(EntityUtils.toString(resEntity));
    }
}

These are the libraries i used for this project,
post simulator

Hope it would help others, have fun (Y)
