您可以使用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;
}
