获取损坏的编码数据，同时将字节数组转换为base64字符串android

Question

我正在开发一个android应用程序在我的应用程序中我想将图像的字节数组转换为base64字符串。但是当我转换时，我得到了损坏的结果。

这是我的AsyncTask

public class Test1 extends AsyncTask<Void, byte[], String> { 
    @Override 
    protected String doInBackground(Void... voids) { 

     try { 
      myClient2 = new Socket("192.168.1.1", 6666); 

      System.out.println("a:" + myClient2); 
      try { 
       JSONObject jsonObject1 = new JSONObject(); 
       jsonObject1.put("cmd", "request_download_file"); 
       jsonObject1.put("file_name", filename1); 
       jsonObject1.put("verification", "CVS"); 


       System.out.println("File name========" + filename1); 

       System.out.println("b111111111111111" + jsonObject1); 
       myClient2.setKeepAlive(true); 
       System.out.println(myClient2.getLocalAddress() + " " + myClient2.getLocalSocketAddress() + " " + myClient2.getKeepAlive()); 
       System.out.println(myClient2.getKeepAlive()); 
       try { 

        DataInputStream dis1 = new DataInputStream(myClient2.getInputStream()); 

        //reads file length from datainputstream 
        DataOutputStream dos1 = new DataOutputStream(myClient2.getOutputStream()); 
        jsonReader1 = new JsonReader(new InputStreamReader(dis1));//, "UTF-8")); 

        InputStreamReader inputReader = new InputStreamReader(dis1); 

        writer1 = new OutputStreamWriter(dos1);//, StandardCharsets.UTF_8) 
        writer1.write(jsonObject1.toString()); 
        System.out.println("c"); 
        writer1.flush(); 

        BufferedInputStream input = new BufferedInputStream(myClient2.getInputStream()); 
        Log.e("input", "input" + input); 

        byte[] data = new byte[1024]; 

        BufferedReader brdr = new BufferedReader(inputReader, 300); 

        boolean status = false; 


        int countPackets = 0; 

        while (!status) { 

         byte[] buffer = new byte[1024]; // or 4096, or more 

         int bytesRead = input.read(buffer, 0, buffer.length); 

         int availableBytes = input.available(); 


         str2 = str2.append(bytesRead); 

         ImageDataArray = concat(ImageDataArray, buffer); 

         countPackets = countPackets + buffer.length; 

         System.out.println(ImageDataArray.length); 




         System.out.println(countPackets); 

         System.out.println("get" + ImageDataArray); 


         String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss") 
           .format(new Date()); 


         System.out.println("check--" + timeStamp + "--"); 


         if (input.available() != 0) { 
          System.out.println("String:" + str1.toString()); 
         } else break; 
        } 

        System.out.println("--------------------out of while ------------------"); 

        System.out.println("filename===========" + filename1); 
        // String filename = String.format("%s%s", Environment.getExternalStorageDirectory().getAbsoluteFile(), "/SteelmanPro/1020/images/image34" + ".jpg"); 

        File file = new File(Environment.getExternalStorageDirectory().getAbsoluteFile().toString(), "/SteelmanPro/1020/images/image"); 



        if (!file.exists()) { 

         file.mkdirs(); 
         System.out.println("File Created++++++++++++++++++"); 

        } 


        int position = - 1; 

        for (int i = 0; i < ImageDataArray.length - 2; i++) { 
         if (ImageDataArray[i] == (byte) 0xff && ImageDataArray[i + 1] == (byte) 0xdf) { 
          position = i; 
          Log.e("position", "position." + position); 

          break; 
         } 
        } 


        write(ImageDataArray,file.toString() +filename1); 


        String encodedImage = Base64.encodeToString((byte[])ImageDataArray, Base64.DEFAULT); 
        Log.i("Base64=========",encodedImage.toString()); 


        int a = data.length; 

        Log.e("data.length", "data.length" + a); 



        System.out.println("String:" + str1.toString()); 
        normalLoginResponse = hexChars; 


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

      } catch (Exception e) { 
       e.printStackTrace(); 
       System.out.println("send JSON error"); 
      } 
      System.out.println("d"); 
      System.out.println("e"); 
      System.out.println("f"); 
      System.out.println("g"); 

     } catch (Exception e) { 
      e.printStackTrace(); 
      System.out.println("creation exception1"); 

     } 

     return normalLoginResponse; 
    } 


    @Override 
    protected void onPostExecute(String response) { 

} 

logcat的

如果有人知道这个请大家帮我

Answer 1

您正在使用的BufferedReader接收图像文件的字节。

这是行不通的，因为您已经看到，作为读者的文本数据。

因此，请放弃它。
