HTTPS的代理Servlet

Question

I have a secure site that needs to display images coming from external non-https URLs on certain pages. I want to create a servlet that is used only as a proxy to pass the image data to the pages. One way is to use Apache's HttpClient to download the image data and then use IOUtils.copy to copy the data to the servlet's response.

Is there a simpler way?

UPDATE: The reason for this is to avoid browser warnings.

This is what I ended up using:

    protected void doGet(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {
        try {
            String url = request.getParameter("url");
            HttpClient httpClient = new DefaultHttpClient();
            HttpGet httpGet = new HttpGet(url);
            HttpResponse httpResponse = httpClient.execute(httpGet);
            HttpEntity httpEntity = httpResponse.getEntity();
            InputStream inputStream = httpEntity.getContent();
            response.setContentType("image/jpeg");
            IOUtils.copy(inputStream, response.getOutputStream());
        } catch (Exception e) {
            AppLogger.log(e);
        }
    }

If anyone has a better way to accomplish this, please post it.

如果我了解得很好，则您不需要这样的东西，只需返回对图像或音频的引用，或HTML响应中的其他任何内容，浏览器就会处理向包含每个资源的服务器发出的请求，如果可以访问，它们将显示在客户端上。
