Question

我正在尝试将文件上传到Parse云。

final ParseFile parseFile = new ParseFile("somefile.png", data);
    parseFile.saveInBackground(new SaveCallback() {
        @Override
        public void done(ParseException e) {
            if (e == null){

                ParseObject parseObject = new ParseObject("photo");
                parseObject.setObjectId("someId");
                parseObject.put("photo1", parseFile);
                parseFile.saveInBackground(new SaveCallback() {
                    @Override
                    public void done(ParseException e) {
                        if (e==null){
                            Log.d(TAG, "Save done");
                        } else {
                            Log.d(TAG, "ex" + e.getMessage());
                        }
                    }
                });

            } else {
                Log.d("USER", "file save ex" + e.getMessage());
            }
        }
    });

这将成功运行并显示＆＃34;保存完成＆＃34;登录。但是当我去Parse仪表板时，我看不到任何数据变化。我试图检索对象：

ParseQuery<ParseObject> query = ParseQuery.getQuery("photo");
    query.getInBackground("someId", new GetCallback<ParseObject>() {
        @Override
        public void done(ParseObject object, ParseException e) {
            if (e == null){
                Log.d("USER", "OK");
            } else {
                Log.d("USER", "ex" + e.getMessage());
            }
        }
    });

但我得到ParseException：no results found for query。

看起来你要保存parseFile两次而忘记保存你放置文件的parse对象。

更改此

parseFile.saveInBackground(new SaveCallback() {
                @Override
                public void done(ParseException e) {
                    if (e==null){
                        Log.d(TAG, "Save done");
                    } else {
                        Log.d(TAG, "ex" + e.getMessage());
                    }
                }
            });

到这个

parseObject.saveInBackground(new SaveCallback() {
                @Override
                public void done(ParseException e) {
                    if (e==null){
                        Log.d(TAG, "Save done");
                    } else {
                        Log.d(TAG, "ex" + e.getMessage());
                    }
                }
            });

快乐的编码。

我认为你会做这样的事情：

// Create the ParseFile
ParseFile parseFile = new ParseFile("somefile.png", data);
file.saveInBackground();

ParseObject imgupload = new ParseObject("photo");
imgupload.put("ImageName", "somefile");
imgupload.put("photo1", parseFile);
imgupload.saveInBackground();

所以，你的查询：

ParseQuery<ParseObject> query = ParseQuery.getQuery("photo");
query.whereEqualTo("ImageName", "somefile");
query.findInBackground(new FindCallback <ParseObject>() {
    @Override
    public void done(ParseObject object, ParseException e) {
        if (e == null){
            Log.d("USER", "OK");
        } else {
            Log.d("USER", "ex" + e.getMessage());
        }
    }
});

Parse.com没有保存ParseObjects
