可以使用MultipartEntity

public static HttpResponse sendImage(byte[] image) { 
    HttpResponse responsePOST = null; 
    try { 
     HttpClient client = new DefaultHttpClient(); 
     HttpPost post = new HttpPost(postURL+"user_profile"); 
     post.setHeader("Accept", "application/json");         
     ByteArrayBody bab = new ByteArrayBody(image, firstname+".png"); 
     MultipartEntity reqEntity = new MultipartEntity(
       HttpMultipartMode.BROWSER_COMPATIBLE);   
     reqEntity.addPart("user_profile[image_attributes[attachment]]", bab);   

     post.setEntity(reqEntity);      
     responsePOST = client.execute(post); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
    return responsePOST; 
}
