Question

我即将编写服务器端应用程序（最可能是PHP但JAVA也可能）和android客户端应用程序。我试图弄清楚将什么是从Android应用程序发送到服务器并在服务器端接收它的最佳方法。如果这样可以优化/序列化一次发送多张图片？请给我一些参考或提示提前谢谢。

你可以使用HTTP帖子。获取ByteArrayOutputStream并压缩JPEG图像并使用ByteArrayBody并使用HttpClient发布它

        ByteArrayOutputStream bos = new ByteArrayOutputStream();

        bm.compress(CompressFormat.JPEG, 75, bos);

        byte[] data = bos.toByteArray();

        HttpClient httpClient = new DefaultHttpClient();

        HttpPost postRequest = new HttpPost(

                "http://10.0.2.2/cfc/iphoneWebservice.cfc?returnformat=json&amp;method=testUpload");

        ByteArrayBody bab = new ByteArrayBody(data, "forest.jpg");

        // File file= new File("/mnt/sdcard/forest.png");

        // FileBody bin = new FileBody(file);

        MultipartEntity reqEntity = new MultipartEntity(

                HttpMultipartMode.BROWSER_COMPATIBLE);

        reqEntity.addPart("uploaded", bab);

        reqEntity.addPart("photoCaption", new StringBody("sfsdfsdf"));

        postRequest.setEntity(reqEntity);

        HttpResponse response = httpClient.execute(postRequest);

        BufferedReader reader = new BufferedReader(new InputStreamReader(

                response.getEntity().getContent(), "UTF-8"));

        String sResponse;

        StringBuilder s = new StringBuilder();



        while ((sResponse = reader.readLine()) != null) {

            s = s.append(sResponse);

        }
