我正在使用 httpCore 来创建自己的基本 Web 服务器。在接收到来自用户的特定请求时，必须启动文件传输操作。我正在使用 HttpRequestHandler 处理请求。我的代码看起来像这样

private HttpRequestHandler mRequestHandler = new HttpRequestHandler()
{
    @Override
    public void handle(HttpRequest request, HttpResponse response, HttpContext httpContext) throws HttpException, IOException
    {
        try{
        HttpEntity entity=null;     
        String contentType="text/html";

        entity = new EntityTemplate(new ContentProducer()
                {
                    public void writeTo(final OutputStream outstream)throws IOException
                    {
                        OutputStreamWriter writer = new OutputStreamWriter(outstream, "UTF-8");
                        String resp = "Server is up and running";

                        writer.write(resp);
                        writer.flush();
                    }
                });

        ((EntityTemplate)entity).setContentType(contentType);

        response.setEntity(entity);
        }catch(Exception e)
        {
            e.printStackTrace();
        }

    }
};

这是一个非常基本的响应，但是我希望将文件从服务器传输到客户端计算机。如何发送文件作为响应？谢谢

我自己想通了。如果有人偶然发现同样的问题，这就是我的工作方式。

private HttpRequestHandler mRequestHandler = new HttpRequestHandler()
    {

        @Override
        public void handle(HttpRequest request, HttpResponse response, HttpContext context)
                throws HttpException, IOException 
            {
            try{
                File file = new File("/mnt/sdcard/Music/song.mp3");
                FileEntity body = new FileEntity(file, "audio/mpeg");
                response.setHeader("Content-Type", "application/force-download");
                response.setHeader("Content-Disposition","attachment; filename=song.mp3");
                response.setEntity(body);

            }catch(Exception e)
            {
                e.printStackTrace();
            }

            }

    };
