如何使用多部分形式的数据JSON发送图像（位图）到服务器的android [英] how to send image (bitmap) to server in android with multipart-form data json

问题描述

我有code图像上传到服务器和它的作品，

  HttpEntity resEntity;

                HttpClient的HttpClient的=新DefaultHttpClient（）;
                HttpPost后=新HttpPost（Constants.url_create_product）;
                MultipartEntity reqEntity =新MultipartEntity（HttpMultipartMode.BROWSER_COMPATIBLE）;
                档案文件=新的文件（路径）;
                FileBody斌=新FileBody（文件）;

                reqEntity.addPart（手机，新StringBody（mPhoneNumber））;
                reqEntity.addPart（prod_title，新StringBody（namapro））;
                reqEntity.addPart（prod_price，新StringBody（hargapro））;
                reqEntity.addPart（prod_desc，新StringBody（despro））;
                reqEntity.addPart（prod_order，新StringBody（orderpro））;
                reqEntity.addPart（prod_image，斌）;

                post.setEntity（reqEntity）;
                    HTT presponse响应= httpClient.execute（后）;
                resEntity = response.getEntity（）;
                字符串response_str = EntityUtils.toString（resEntity）;
                GSON GSON =新GSON（）;
                gson.toJson（response_str）;
                 如果（resEntity！= NULL）{
                     Log.i（响应，response_str）;
                     runOnUiThread（新的Runnable（）{
                            公共无效的run（）{
                                 尝试 {
                                    Toast.makeText（getApplicationContext（），上传完成检查服务器的上传目录。，Toast.LENGTH_LONG）.show（）;
                                }赶上（例外五）{
                                    e.printStackTrace（）;
                                }
                               }
                        }）;
                 }
 

但我有菜单图像编辑器。该编辑器是作物的形象和多数民众赞成在code返回位图这样的值

 捆绑额外= data.getExtras（）;

                如果（临时演员！= NULL）{
                    照片= extras.getParcelable（数据）;

                    mImageView.setImageBitmap（照片）;
                }

                文件F =新的文件（mImageCaptureUri.getPath（））;

                如果（f.exists（））f.delete（）;

                打破;
 

我想请问，怎么解决方案发送图像服务器参数位图。正如你知道我的code立即发送图像使用参数路径（字符串）。

解决方案

  ByteArrayOutputStream BAOS =新ByteArrayOutputStream（）;
photo.com preSS（Bitmap.Com pressFormat.JPEG，100，BAOS）;
byte []的imageBytes = baos.toByteArray（）;
字符串连接codeDIMAGE = Base64.en codeToString（imageBytes，Base64.DEFAULT）;
 

然后发送该连接codeDIMAGE为字符串和你的服务器，你需要去code是为了得到图像本身。

I have code to upload image to server and it works ,

HttpEntity resEntity;

                HttpClient httpClient = new DefaultHttpClient();
                HttpPost post = new HttpPost(Constants.url_create_product);
                MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
                File file= new File(path);
                FileBody bin = new FileBody(file);

                reqEntity.addPart("phone", new StringBody(mPhoneNumber));
                reqEntity.addPart("prod_title", new StringBody(namapro));
                reqEntity.addPart("prod_price", new StringBody(hargapro));
                reqEntity.addPart("prod_desc", new StringBody(despro));
                reqEntity.addPart("prod_order", new StringBody(orderpro));
                reqEntity.addPart("prod_image", bin);

                post.setEntity(reqEntity);
                    HttpResponse response = httpClient.execute(post);
                resEntity = response.getEntity();
                String response_str = EntityUtils.toString(resEntity);
                Gson gson = new Gson(); 
                gson.toJson(response_str);
                 if (resEntity != null) {
                     Log.i("RESPONSE",response_str);
                     runOnUiThread(new Runnable(){
                            public void run() {
                                 try {
                                    Toast.makeText(getApplicationContext(),"Upload Complete. Check the server uploads directory.", Toast.LENGTH_LONG).show();
                                } catch (Exception e) {
                                    e.printStackTrace();
                                }
                               }
                        });
                 }

But i have menu image editor . that editor is crop image and thats code return bitmap value like this

Bundle extras = data.getExtras();

                if (extras != null) {               
                    photo = extras.getParcelable("data");

                    mImageView.setImageBitmap(photo);
                }

                File f = new File(mImageCaptureUri.getPath());            

                if (f.exists()) f.delete();

                break;

I wanna ask , how solution to send image to server with parameter bitmap. As you know my code to send image now use parameter path (string).

解决方案

ByteArrayOutputStream baos = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] imageBytes = baos.toByteArray();
String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);

Then send this encodedImage as a String and in your server you will need to decode it in order to get the image itself.
