android - 将二进制流转换为字节？

Question

我有二进制流，我希望它以字节为单位进行转换。之后我想将它下载到 SD 卡中。

我的网络服务:

    POST /**********Mobile/**********.asmx HTTP/1.1
    Host: ***.***.*.*
    Content-Type: text/xml; charset=utf-8
    Content-Length: length
    SOAPAction: "http://tempuri.org/GetDocument"

    <?xml version="1.0" encoding="utf-8"?>
    <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

    <soap:Body>
        <GetDocument xmlns="http://tempuri.org/">
           <DocumentID>string</DocumentID>
       </GetDocument>
    </soap:Body>
 </soap:Envelope>
HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      
xmlns:xsd="http://www.w3.org/2001/XMLSchema"     
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
  <GetDocumentResponse xmlns="http://tempuri.org/">
    <GetDocumentResult>string</GetDocumentResult>
  </GetDocumentResponse>
</soap:Body>
</soap:Envelope>

我正在尝试的是

 SoapObject DocumentRequest = new SoapObject(NAMESPACE, GET_DOCUMENT_METHOD);
        
        DocumentRequest.addProperty("DocumentID", ID);
        Log.i("DocumentID", ID);

        SoapSerializationEnvelope Envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        Envelope.dotNet = true;
        Envelope.setOutputSoapObject(DocumentRequest);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        androidHttpTransport.debug = true;
        
        androidHttpTransport.call(SOAP_ACTION_GETDOCUMENT, Envelope);
        
        SoapPrimitive DocumentResponse = (SoapPrimitive)Envelope.getResponse();
        Log.i("DocumentResponse", DocumentResponse.toString());
        
        String DocAsString = DocumentResponse.toString();
        
        byte[] decodedString = DocAsString.getBytes();
        
        Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
        ImageView DisplayDoc= (ImageView)findViewById(R.id.displayimage);
        DisplayDoc.setImageBitmap(decodedByte);
}

我正在获取二进制流，因为字符串是正确的，或者我需要使用 base64binary。如果是这样，请告诉我下载 image/.pdf/word 文档的正确方法。我已经完成了差异搜索，但没有用。谢谢

编辑:

SoapPrimitive DocumentResponse = (SoapPrimitive)Envelope.getResponse();
        Log.i("DocumentResponse", DocumentResponse.toString());
        
        String DocAsString = DocumentResponse.toString();
        
        byte[] decodedString = Base64.decode(DocAsString, Base64.DEFAULT);
        
        /*Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
        ImageView DisplayDoc= (ImageView)findViewById(R.id.displayimage);
        DisplayDoc.setImageBitmap(decodedByte);*/
        
         File direct = new File(Environment.getExternalStorageDirectory() + "/Downloads");

         if(!direct.exists())  {
             direct.mkdir(); }
        File photo=new File(Environment.getExternalStorageDirectory() + "/Downloads", ID);

         if (photo.exists()) {
              photo.delete(); }

     try {
       FileOutputStream fos=new FileOutputStream(photo.getPath());

       fos.write(decodedString);
       fos.close();

       ContentValues values= new ContentValues();
       
       System.out.println(values);

     }
     catch (java.io.IOException e) 
     {
       Log.e("PictureDemo", "Exception in photoCallback", e);
     }
    }
    catch(Exception e) {
        e.printStackTrace();
        Toast.makeText(getApplicationContext(), " Network Exception : " + e
                + "Please check network connectivity.", Toast.LENGTH_LONG).show();
    }
}

Answer 1

                    try {
                    ht.call(SOAP_ACTION, envelope);

                    final SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
                    String str =DocumentResponse.toString();

                        byte[] decodedString = Base64.decode(str, Base64.DEFAULT);

                   File direct = new File(Environment.getExternalStorageDirectory() + "/Foldername");

                      if(!direct.exists())
                      {
                          direct.mkdir();
                      }

                    File photo=new File(Environment.getExternalStorageDirectory() + "/Foldername",Filename);


                  if (photo.exists())
                  {
                        photo.delete();
                  }

                  try {
                    FileOutputStream fos=new FileOutputStream(photo.getPath());

                    fos.write(decodedString);
                    fos.close();

                    ContentValues values= new ContentValues();

                  }
                  catch (java.io.IOException e) 
                  {
                    Log.e("PictureDemo", "Exception in photoCallback", e);
                  }
                }


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

将您的字符串转换为 Base64 解码。

例子:byte[] decodedString = Base64.decode(str, Base64.DEFAULT);

使用该字节将文件保存在 SDCard 中。

例子:fos.write(decodedString);
