как создать изображение в jsonobject

Question

Я хочу поместить изображение в jsonobject, поэтому преобразовал его в строку, используя (base64-encodetostring), и я не думаю, что из-за флага encodetostring base64 или idk, я пробовал несколько способов решения проблемы, ничего не помогает, и никаких решений вИнтернет.

Я пробовал флаг base64.DEFAULT, и любой отдельный FLAG ничем не помогает, потому что я думаю, что это потому, что base64.encodetostring не устанавливает конец строки или не знает точно, что это такое

                pdp.compress(Bitmap.CompressFormat.JPEG,100,bytes);

                byte[] bytes1=bytes.toByteArray();

                Pdp= Base64.encodeToString(bytes1,Base64.NO_WRAP|Base64.URL_SAFE);

и я поместил точную строку Pdp в jsono

                query.put("new_pdp",",pdp=cast('"+pdp+"==' as varbinary(max))");
            }else query.put("new_pdp","");

Я записал ее на консоль, и это результат только закодированных байтов:

Answer 1

Декодирование и кодирование Base64 может занимать очень много памяти. Если изображение находится на сервере, просто захватите URL и запросите его.

Answer 2

, как упомянуто выше @Haider Malik, кодирование и декодирование base64 не требуют памяти, в качестве решения вы можете использовать firestore из firebase в качестве поставщика БД и загружать туда изображения. пример загрузки изображения будет выглядеть так:

    InputStream stream = new FileInputStream(new File("path/to/images/rivers.jpg"));

uploadTask = mountainsRef.putStream(stream);
uploadTask.addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception exception) {
        // Handle unsuccessful uploads
    }
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
    @Override
    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
        // taskSnapshot.getMetadata() contains file metadata such as size, content-type, etc.
        // ...
    }
});StorageActivity.java

Answer 3

Вот как я это сделал:

     String photoEncodedString = ""; 

    if (this.theBitmap != null) {           
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        this.theBitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
        byte[] bytes = stream.toByteArray();
        photoEncodedString = Base64.encodeToString(bytes, Base64.DEFAULT);
    }

    String dataString = "[{";

    dataString = dataString + "\"PhotoImage\": \"" + photoEncodedString + "\" ";        
    dataString = dataString + ",\"Name\": \"" + etYourName.getText().toString() + "\" ";
    dataString = dataString + ",\"Email\": \"" + etEmail.getText().toString() + "\" ";
    dataString = dataString + ",\"Comments\": \"" + tvCommentsValue.getText().toString() + "\" ";

    dataString = dataString + "}]";

    JSONObject jObj = new JSONObject(dataString);

Я думаю, что ваша ошибка .put связана с неправильным форматированием вашего JSON.У вас есть

    { "operation":"edit_profile",
"username":"frsyescd",
"password":"123Ch@rif",
"new_email":"",
"new_pdp":",pdp=cast('_9j_4AAQSkZJRgABAQAAAQABAAD

Там, где перед pdp = cast стоит запятая.
Также "new_pdp": "pdp = cast (" также не будет действительным JSON.

IЯ просто говорю, что это недопустимый JSON, поэтому он может вызвать ошибку где-то:

 "new_pdp":",pdp=cast('_9j_4AAQSkZJRgABAQAAAQABAAD..._svmCveT8v

Вы не заканчиваете строку, основываясь на том, что вы опубликовали выше, вам нужно, чтобы она выглядела болеевот так, чтобы он был действительным JSON:

"new_pdp":"_9j_4AAQSkZJRgABAQAAAQABAAD..._svmCveT8v"

Вот снова мой код, но с нужным вам форматом JSON:

 String photoEncodedString = ""; 

if (pdp != null) {           
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    pdp.compress(Bitmap.CompressFormat.PNG, 100, stream);
    byte[] bytes = stream.toByteArray();
    photoEncodedString = Base64.encodeToString(bytes, Base64.DEFAULT);
}

String dataString = "[{";

dataString = dataString + "\"operation\":\"edit_profile\" ";        
dataString = dataString + ",\"username\":\"frsyescd\" ";
dataString = dataString + ",\"password\":\"123Ch@rif\" ";
dataString = dataString + ",\"new_pdp\":\"" + photoEncodedString + "\""; 

dataString = dataString + "}]";

JSONObject jObj = new JSONObject(dataString);
