Android 解析服务器保存图像不工作

Question

我正在尝试将图像上传到我在 AWS 和 mongoLab 上的解析服务器。但是，每当我尝试使用下面的代码添加图像时，都会出现错误，当我尝试保存没有图像的对象时，它会成功。难道我做错了什么。我试了 10 多个小时都没成功。

ParseFile image1;

Bitmap bm = BitmapFactory.decodeResource(getResources(),
        R.drawable.ph);

ByteArrayOutputStream stream = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();

image1 = new ParseFile("profilePhoto.png", byteArray);
image1.saveInBackground();


JSONArray myFriendList = new JSONArray();
myFriendList.put("xxxxxxxxxxxxxxx");
myFriendList.put("yyyyyyyyyyyyyyy");

ParseObject userSettingObj = new ParseObject("userSetting");
userSettingObj.put("profileName", profileNameField.getText().toString());
userSettingObj.put("userid", ParseUser.getCurrentUser().getObjectId());
userSettingObj.put("name", nameField.getText().toString());
userSettingObj.put("surname", surnameField.getText().toString());
userSettingObj.put("friendList", myFriendList);

userSettingObj.put("photo", image1);

userSettingObj.saveInBackground(new SaveCallback() {
    @Override
    public void done(ParseException e) {

        if (e == null) {

            System.out.println("saved successfully");

        } else {

            System.out.println("error while saving");

        }

    }
});

试试这个然后告诉我。

    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bm.compress(Bitmap.CompressFormat.PNG, 100, stream);
    byte[] byteArray = stream.toByteArray();
image1 = new ParseFile("profilePhoto.png", byteArray);
image1.saveInBackground(new SaveCallback() {
        @Override
        public void done(ParseException e) {

            if (e == null) {
    upload();
            } else {

            }

        }
    });

    public void upload(){
JSONArray myFriendList = new JSONArray();
    myFriendList.put("xxxxxxxxxxxxxxx");
    myFriendList.put("yyyyyyyyyyyyyyy");

    ParseObject userSettingObj = new ParseObject("userSetting");
    userSettingObj.put("profileName",    profileNameField.getText().toString());
    userSettingObj.put("userid", ParseUser.getCurrentUser().getObjectId());
    userSettingObj.put("name", nameField.getText().toString());
    userSettingObj.put("surname", surnameField.getText().toString());
    userSettingObj.put("friendList", myFriendList);

    userSettingObj.put("photo", byteArray);

    userSettingObj.saveInBackground(new SaveCallback() {
        @Override
        public void done(ParseException e) {

            if (e == null) {

                System.out.println("saved successfully");

            } else {

                System.out.println("error while saving");

            }

        }
    });}

经过几个小时的努力，我终于能够在 Parse DataBase 上上传 Parse 文件要遵循的步骤： 1 - 首先编写注册查询。 2 - 成功响应注册查询后，您将获得当前用户对象 ID。 3- 然后在 Parse 数据库 "profilePictureTable" 中创建一个自定义 Class 并添加某些列 1- profilePicture。 2- 用户对象 ID。 4- 然后最后调用回调 SaveInBackground

    Bitmap bitmap = BitmapFactory.decodeFile("Your File Path");
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
    final byte[] data = stream.toByteArray();


    final ParseFile file = new ParseFile("profile_pic.png", data);

    file.saveInBackground();

    final ParseObject profilePicture = new ParseObject("profilePictureTable");
    profilePicture.put("profilePicture", file);
    profilePicture.put("userObjectId",ParseUser.getCurrentUser().getObjectId());

    profilePicture.saveInBackground(new SaveCallback()
    {
        @Override
        public void done(ParseException e)
        {
            if (e == null)
            {
                Log.i("Parse", "saved successfully");


            }
            else
            {
                Log.i("Parse", "error while saving");
            }
        }
    });
