如何去code图像串从PHP服务器位图图像？ [英] How to decode the image string to bitmap image from php server?

问题描述

在我的应用程序必须从图库中选择图像，并将其设置为资料图片。对于我都设有codeD图像作为字符串，并将其发送到服务器。正从服务器的响应后，我要脱code中的字符串图像为位图从服务器接收image.While响应它显示了以下错误

In my application i have to select an image from gallery and set it as an profile picture. For that i have encoded the image as string and send it to the server. After getting the response from server i want to decode the string image to bitmap image.While receiving response from the server it shows the following error

java.lang.IllegalArgumentException: bad base-64
at android.util.Base64.decode(Base64.java:161)
at android.util.Base64.decode(Base64.java:136)
at android.util.Base64.decode(Base64.java:118) 

下面code我使用的base64方法将位图图像转换为字符串，

Below code i use the base64 method to convert the bitmap image to string,

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK
                && null != data) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };

            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();
            profileimage.setImageBitmap(BitmapFactory.decodeFile(picturePath));
            profileimage.buildDrawingCache();
            Bitmap bm = profileimage.getDrawingCache();

            ByteArrayOutputStream bao = new ByteArrayOutputStream();

            // Resize the image
            double width = bm.getWidth();
            double height = bm.getHeight();
            double ratio = 100 / width;
            int newheight = (int) (ratio * height);

            System.out.println("———-width" + width);
            System.out.println("———-height" + height);
            System.out.println("———-height" + newheight);

            bm = Bitmap.createScaledBitmap(bm, 100, newheight, true);

            // Here you can define .PNG as well
            bm.compress(Bitmap.CompressFormat.JPEG, 95, bao);
            byte[] ba = bao.toByteArray();
            ba1 = Base64.encodeToString(ba, Base64.NO_WRAP);

            System.out.println("uploading image now ——–" + ba1);

        }

    }

code服务器调用

Code for server call

public String makeServiceCall1(String url1, String a, final Context context) {
        this.url = url1;
        ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
        nameValuePairs.add(new BasicNameValuePair("profileimage", a));
        try {

            if (!isConnected(context)) {

                return url;
            }
            if (isConnected(context) == false) {
                Toast.makeText(context, "No Connection Available", 500).show();
            }

            URI uri = new URI(url.replace(" ", "%20"));
            Log.d("uri", url + "");

            HttpPost httppost = new HttpPost(uri);
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            HttpParams httpParameters = httppost.getParams();

            int timeoutConnection = 100000;
            HttpConnectionParams.setConnectionTimeout(httpParameters,
                    timeoutConnection);

            int timeoutSocket = 100000;
            HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

            HttpResponse response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();

            List<Cookie> cookies = httpclient.getCookieStore().getCookies();
            if (cookies.isEmpty()) {
                System.out.println("None");
            } else {
                for (int i = 0; i < cookies.size(); i++) {
                    System.out.println("- " + cookies.get(i).toString());
                }
            }
            int responseCode = response.getStatusLine().getStatusCode();

            if (response != null) {
                msg = EntityUtils.toString(entity);

            }
            Log.d("serverResponse", msg);

        } catch (Exception e) {
            e.printStackTrace();
        }
        return msg;
        // TODO Auto-generated method stub

    }

code的图像刺痛转换为位图图像，

Code for convert the image sting to bitmap image,

byte[] decodedString = Base64.decode(image, Base64.NO_WRAP);
    Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0,
            decodedString.length);
profilepic.setImageBitmap(decodedByte);

请任何一个可以帮助我解决这个问题。

Please any one help me to solve the issue.

推荐答案

请恩$ C $使用此套餐C

Please Encode using this package

 import org.kobjects.base64.Base64;

和也使用了这种

ba1 = Base64.encodeToString(ba, Base64.DEFAULT);
