还有我的异步任务类

  public class AddShopTask extends AsyncTask<String, Void, String> {

      private ProgressDialog pDialog1;

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        pDialog1 = new ProgressDialog(AddShopActivity.this);
        pDialog1.setMessage(getString(R.string.ip_updating_the_server));
       pDialog1.setIndeterminate(false);
        pDialog1.setCancelable(false);
        pDialog1.show();
    }

    @Override
    protected String doInBackground(String... params) {

        String shopName = mShopNameEditText.getText().toString();
        String shopDescription = mShopServiceDescription.getText().toString();
        String landMark = mShopAddress.getText().toString();
        String userType = "2";
        String shopMobileNo = mShopMobileNumber.getText().toString();
        String shopEmailId = mShopEmailId.getText().toString();
        String shopPicture = encodeImageToB64Format();
        String createdOn = String.valueOf(System.currentTimeMillis());
        return HttpConnectionUtils.getAddShopResponse(shopName, shopPicture, landMark,
                mShopCityName, shopMobileNo, shopEmailId, shopDescription, "paymentDetails",
                createdOn, "78.37492398", "87.238829323", userType, shopPicture);
    }

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);
        pDialog1.dismiss();
        if (result != null && !result.trim().equals("")) {
            try {
                JSONObject loginResponseObj = new JSONObject(result);
                String loginState = loginResponseObj.getString("result");

                if (loginState.equals("success")) {

                    Toast.makeText(AddShopActivity.this, "Shop Added Successfully",
                            Toast.LENGTH_LONG).show();
                    finish();
                } else {
                    iPreferenceUtils.clearAllPreferences(AddShopActivity.this);
                    Intent intent = new Intent(AddShopActivity.this, LoginActivity.class);
                    startActivity(intent);
                    finish();
                }
            } catch (Exception e) {

            }
        } else {
            Crouton.makeText(AddShopActivity.this, R.string.err_check_your_connection,
                    Style.ALERT).show();
        }
    }
}

private String encodeImageToB64Format() {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    profilePhoto.compress(Bitmap.CompressFormat.JPEG, 100, baos);
    byte[] imageByte = baos.toByteArray();
    String encodeShopImage = Base64.encodeToString(imageByte, Base64.NO_PADDING);

    return encodeShopImage;
}

Answer 1

位置 76 听起来像是行尾 - 而且几乎是。 Base64 文本通常被分成少于 80 个字符的行，从而添加换行符。对于某些解码器，首先必须删除\r 和\n。

String encodeShopImage = Base64.encodeToString(imageByte,
        Base64.NO_PADDING|Base64.NO_WRAP);

填充导致尾随填充符，如“---”，换行导致行尾。

或

return encodeShopImage.replaceAll("[^A-Za-z0-9/+]", "");

粗略地删除所有非 Base64 字符。
