HTTPS的代理Servlet [英] Proxy Servlet for HTTPS

问题描述

我有一个安全的网站，需要在某些网页上显示来自外部非https网址的图片。我想创建一个仅用作代理的servlet，将图像数据传递给页面。一种方法是使用Apache的HttpClient下载图像数据，然后使用IOUtils.copy将数据复制到servlet的响应中。

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.

有更简单的方法吗？

更新：原因是避免浏览器警告。

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

推荐答案

这就是我最终使用的结果：

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);
        }
    }
