目的:
我有一个S3视频网址和S3 Image网址。 S3存储桶具有私有访问权限(非公开)。我有一个"访问密钥ID"和#34;秘密访问密钥"访问S3存储桶。我必须在屏幕上显示S3图像/视频而不在本地存储。我正在使用play framework 2.5.3和scala语言。
我尝试了什么:
我在互联网上搜索过。我使用下面的插件来使用S3。
https://github.com/seratch/AWScala
https://github.com/Kaliber/play-s3
通过使用上述插件,我们可以读取图像/视频文件内容。但我不想阅读整个文件内容。我想在视图中显示图像/视频而不存储在本地。
我想要的是什么:
如果有人提出他们的建议会有所帮助。
1)是否可以使用"访问密钥ID"从S3 URL播放视频和显示图像。和#34;秘密访问密钥"在我的Play scala应用程序中。
2)如果是,请分享这样做的方式。感谢!!!

我尝试过以下方式:
public class SearchResult extends AppCompatActivity {
private ListView lvSearch;
private ProgressDialog dialog;
private final String URL_TO_HIT = "http://www.abcd.com/mobile_search.php";
private String location = "bathinda";

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search_result);
setContentView(R.layout.activity_search_result);

toolbar.setTitle("Search Result");
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
onBackPressed();
}
});
dialog = new ProgressDialog(this);
dialog.setIndeterminate(true);

Bundle bundle = getIntent().getExtras();
String bar = bundle.getString("bar");

String deals = bundle.getString("deals");
// To start fetching the data when app start, uncomment below line to start the async task.
new JSONTask().execute(URL_TO_HIT, location, bar, nights, nearby, deals );
}
public class JSONTask extends AsyncTask<String,String, List<SearchData> >{

while ((line = reader.readLine()) != null){
buffer.append(line);
}
String finalJson = buffer.toString();

List<SearchData> searchDataList = new ArrayList<>();
Gson gson = new Gson();
for(int i=0; i<parentArray.length(); i++) {

/**

*/
SearchData searchData = gson.fromJson(finalObject.toString(), SearchData.class);
searchDataList.add(searchData);
}
return searchDataList;
} catch (MalformedURLException e) {

}
return null;
}
@Override

super.onPostExecute(result);
dialog.dismiss();
if(result != null) {
SearchAdapter adapter = new SearchAdapter(getApplicationContext(), R.layout.searchresultrow, result);

}
}
}

//final ProgressBar progressBar = (ProgressBar)convertView.findViewById(R.id.progressBar);

holder.barname1.setText(searchDataList.get(position).getBarname());
holder.address1.setText(searchDataList.get(position).getLocation());

private TextView address1;
private TextView offer1;
private TextView hourtext1;
private TextView coststext1;
private TextView textv11;
private TextView barname1;
private TextView featuredtext1;
}
}
但我确实得到了以下异常 - 错误:: orginalUri
上述实施有什么问题?
