未能在json中放入Base64字符串

我的Base64字符串是從照片轉換而來的。我嘗試將它們放入我的json對象中，但會導致部分Base64字符串被切割，甚至其他json對象可能會消失。當我用短的Base64字符串替換原來的那個時，json格式就可以了。我怎麼能修好它？未能在json中放入Base64字符串

public void TakePhotoOnClick(View view) { 
    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 

    file = Environment 
      .getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES); 
    file = new File(file, "picture.jpg"); 
    cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file)); 
    if (isIntentAvailable(this, cameraIntent)) { 
     startActivityForResult(cameraIntent, REQUEST_TAKE_PICTURE); 
    } else { 
     Toast.makeText(this, R.string.msg_NoCameraAppsFound, 
       Toast.LENGTH_SHORT).show(); 
    } 

} 

private boolean isIntentAvailable(Context context, Intent intent) { 
    PackageManager packageManager = context.getPackageManager(); 
    List<ResolveInfo> list = packageManager.queryIntentActivities(intent, 
      PackageManager.MATCH_DEFAULT_ONLY); 
    return list.size() > 0; 
} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    Log.w(" MainActivity","onActivityResult"); 
    if (requestCode == REQUEST_TAKE_PICTURE && resultCode == RESULT_OK) { 

     Bitmap picture = BitmapFactory.decodeFile(file.getPath()); 
     ivDriverPhoto.setImageBitmap(picture); 

     ByteArrayOutputStream out1 = new ByteArrayOutputStream(); 
     picture.compress(Bitmap.CompressFormat.JPEG, 50, out1); 
     image = out1.toByteArray(); 
     driver_photo = Base64.encodeToString(image, Base64.DEFAULT); 
     Log.w(" MainActivity","image"+ driver_photo); 

    } 

}

照片Base64編碼字符串是類似以下字符串： 圖像/ 9J/4AAQSkZJRgABAQAAAQABAAD/2wBDABALDA4MChAODQ4SERATGCgaGBYWGDEjJR0oOjM9 ... （它太長了，完全表現出來）

和短測試BASE64斯汀是如下： 圖像/ PNG; BASE64，iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAQAAAC1 + jfqAAAAAnNCSVQICFXsRgQAAAAJcEhZcwAAAHoAAAB6AZUMqX8AAAAZdEVYdFNvZnR3YXJlAHd3dy5pbmtzY2FwZS5vcmeb7jwaAAAA4ElEQVQoz6XRzyvDcRgH8JdJObmsJMUf4KIotaJEUYrLNPnxTY4r3Ocw32K + HwpxmZ1cN H/C/rzHYVvNZQ56X1/P09P7EcbHn0AmH5OMYux8QQqmXSk8K8yasCWX2zMZpD44txSCDccOVZVsaqiPgm + v2roqntxpq/n0oTQEy05CcGnem1YIrnSUByDIzVlwY1FNS + bIix1rww3beh4kPR119y6cSs40JJIDTeuaCquSjtsQXHu32wePSkHZTNA0paFqX2FCkij6VwyKyUOwohKCpCDTHan261fRXZl/F/MHNSqo8Xq9umsAAAAASUVORK5CYII =

所以你的問題是當你試圖把'driver_photo'放入一個JSON對象？在你的代碼中沒有任何與json相關的東西......同樣奇怪的是，兩個base64字符串在開頭都有'image /'...它們是由Base64.encode生成的？ – Salem

是的，Photo Base64字符串來自Log（Log.w（「MainActivity」，「image」+ driver_photo））。 –

我通過使用BitmapFactory以減小圖像尺寸和Base64編碼的字符串將是足夠短以投入JSON解決問題。
