关于android AsyncTask 上传图片的问题

Question

 public  class FileUploadTask extends AsyncTask<Object, Integer, Void> {  
  
private ProgressDialog dialog = null;  
        HttpURLConnection connection = null;  
        DataOutputStream outputStream = null;  
        DataInputStream inputStream = null;  
        //图片地址 
        String uploadedFile = path;  
        //上传图片网址
        String url = "http://192.168.1.38/camera10/photosumbit.php";  
        String lineEnd = "\r\n";  
        String twoHyphens = "--";  
        String boundary = "*****";  
  
        File uploadFile = new File(uploadedFile);  
        long totalSize = uploadFile.length(); // 获取文件的大小 
  
        @Override  
        protected void onPreExecute() {  
            dialog = new ProgressDialog(EditActivity.this);  
            dialog.setMessage("正在上传...");  
            dialog.setIndeterminate(false);  
            dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);  
            dialog.setProgress(0);  
            dialog.show();
            
            
        }  
  
        @Override  
        protected Void doInBackground(Object... arg0) {  
  
            long length = 0;  
            int progress;  
            int bytesRead, bytesAvailable, bufferSize;  
            byte[] buffer;  
            int maxBufferSize = 256 * 1024;// 256KB  
  
            try {  
                FileInputStream fileInputStream = new FileInputStream(new File(  
                        uploadedFile));  
  
                URL urlstr = new URL(url);  
                connection = (HttpURLConnection) urlstr.openConnection();  
  
                  
                connection.setChunkedStreamingMode(128 * 1024);// 128KB  //上传速度限制
  
                // 可以读取  
                connection.setDoInput(true);  
                connection.setDoOutput(true);  
                connection.setUseCaches(false);  
  
                //用post方法上传
                connection.setRequestMethod("POST");  
                connection.setRequestProperty("Connection", "Keep-Alive");  
                connection.setRequestProperty("Charset", "UTF-8");  
                connection.setRequestProperty("Content-Type",  
                        "multipart/form-data;boundary=" + boundary);  
                
                //int userId=UserHelper.userId;
                outputStream = new DataOutputStream(connection.getOutputStream()); 
                //outputStream.writeInt(userId);
                
                outputStream.writeBytes(twoHyphens + boundary + lineEnd);  //上传文件格式
                outputStream  
                        .writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\""  
                                + uploadedFile + "\"" + lineEnd);  
   
                outputStream.writeBytes(lineEnd);  
                 
                bytesAvailable = fileInputStream.available();  
                bufferSize = Math.min(bytesAvailable, maxBufferSize);  
                buffer = new byte[bufferSize];  
  
                // 读取文件  
                bytesRead = fileInputStream.read(buffer, 0, bufferSize);  
              
                  
                     
                    //ds.write(value.getBytes("UTF-8"));  
                  
                
                while (bytesRead > 0) {  
                    outputStream.write(buffer, 0, bufferSize);  
                    length += bufferSize;  
                    progress = (int) ((length * 100) / totalSize);  
                    publishProgress(progress);  
  
                    bytesAvailable = fileInputStream.available();  
                    bufferSize = Math.min(bytesAvailable, maxBufferSize);  
                    bytesRead = fileInputStream.read(buffer, 0, bufferSize);  
                }  
                outputStream.writeBytes(lineEnd);  
                outputStream.writeBytes(twoHyphens + boundary + twoHyphens  
                        + lineEnd);  
                publishProgress(100);  
                
                // 获取服务器信息  
                int serverResponseCode = connection.getResponseCode();  
                String serverResponseMessage = connection.getResponseMessage();  
  
                 
                fileInputStream.close(); 
                
                    //写入int数据  
                  
                //outputStream.writeInt(userId);
                outputStream.flush(); 
                
                outputStream.close();  
               
            } catch (Exception ex) {  
            }  
            return null;  
        }  
  
        @Override  
        protected void onProgressUpdate(Integer... progress) {  
            dialog.setProgress(progress[0]);  
        }  
  
        @Override  
        protected void onPostExecute(Void result) {  
            try {  
                dialog.dismiss();  
                // TODO Auto-generated method stub  
            } catch (Exception e) {  
            }  
        }  
  
    }  我想在这个类里上传图片的同时，上传一个int变量，然后在服务器那边通过post获取这个int的值

Answer 1

再增加一个
connection.setRequestProperty("变量名", 数值);
