image uploaded by android is empty to laravel

Android is uploading image from my laravel 5.7 API but the
$request->input('image') is always on empty. I also try it using postman and its working fine. can someone help me out? XD
success result using post man form-data type
if($request->hasFile('image'))
{
$image = $request->file('image');
$name = time().'.'.$image->getClientOriginalExtension();
$destinationPath = public_path('uploads/messenger');
$image->move($destinationPath, $name);
$path = url('')."/webservices/public/uploads/messenger/".$name;
$result=[
"image_url" => $path,
];
$succes = "1";
$successMessage = "Image uploaded";
$errorMessage = "";
}
else
{
$result = (object) array();
$succes = "0";
$successMessage = "";
$errorMessage = "Image not found";
}

use Storage Facades for storing file :
create folder inside storage/app/public/uploads/messenger : with 777 permission
run command : php artisan storage:link to symlink your storage folder content available to public folder
in your controller :
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
use Illuminate\Support\Facades\Storage;
use Carbon\Carbon;
public function upload_image(Request $request){
try{
// added validator for image field
$validator = Validator::make($request->all(), [
'image'=>'required|mimes:jpeg,jpg,png,gif|max:5120'
]);
if ($validator->fails()) {
$response=array('status'=>'error','result'=>0,'errors'=>implode(',',$validator->errors()->all()));
return response()->json($response, 200);
}else{
if($request->hasFile('image')){
$uniqueid=uniqid();
$original_name=$request->file('image')->getClientOriginalName();
$size=$request->file('image')->getSize();
$extension=$request->file('image')->getClientOriginalExtension();
$filename=Carbon::now()->format('Ymd').'_'.$uniqueid.'.'.$extension;
$imagepath=url('/storage/uploads/messenger/'.$filename);
$path=$request->file('image')->storeAs('public/uploads/messenger/',$filename);
$response=array('status'=>'success','result'=>1,'image'=>$imagepath);
return response()->json($response, 200);
}else{
$response=array('status'=>'error','result'=>0,'errors'=>'no image found');
return response()->json($response, 200);
}
}
}catch(\Exception $e){
$response=array('status'=>'error','result'=>0,'errors'=>'Internal Server Error');
return response()->json($response, 500);
}
}
add Content-Type : multipart/form-data header when uploding image from client side like android or postman

Image upload in an Oracle database using Zend Framework

I am uploading an image from my android application and trying to store the image as Blob in Oracle database using PHP. I used the same technique for uploading the image in my web application which worked fine. I am trying the following code. Need some assistance. TIA
<?php
$conn = oci_connect("test_dev","test_dev","192.168.10.82:1509/testdv");
class emp{}
$image = $_POST['image'];
$name = $_POST['name'];
if (empty($name)) {
$response = new emp();
$response->success = 0;
$response->message = "Please dont empty Name.";
die(json_encode($response));
} else {
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$mime = finfo_file($finfo, $image);
$DIGI_TYPE= $mime;
$lob = oci_new_descriptor($conn, OCI_D_LOB);
$myv = file_get_contents($image);
$imageProperties = getimageSize($image);
$lob->writeTemporary($myv, OCI_TEMP_BLOB);
$sql = "UPDATE LC_BLOCK_LIST_TECH_PERS
SET DIGI_SIGN = :DIGI_SIGN , DIGI_TYPE = :DIGI_TYPE
WHERE COM_CODE= '$name'";
$s = oci_parse($conn, $sql);
oci_bind_by_name($s, ':DIGI_TYPE', $DIGI_TYPE);
oci_bind_by_name($s, ':DIGI_SIGN', $lob, -1, OCI_B_BLOB);
oci_execute($s, OCI_NO_AUTO_COMMIT);
oci_commit($conn);
$lob->close();
`

<?php
$conn = oci_connect("DRUG_FINAL","DRUG_FINAL","192.168.10.85:1521/devdb");
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
else{
echo "connected";
}
$image = $_POST['image'];
$name = $_POST['name'];
if(isset($_POST["image"]) && isset($_POST["name"]))
{
$title = $_POST["name"];
$image = $_POST["image"];
$gambar = file_get_contents($image);
$gambar1 =file_put_contents(base64_decode($gambar1));
$query = "INSERT INTO images (TITLE, IMAGES) VALUES (:TITLE, EMPTY_BLOB()) RETURNING IMAGES INTO :IMAGES";
$parse = oci_parse($conn, $query);
$lob_a = oci_new_descriptor($conn, OCI_D_LOB);
oci_bind_by_name($parse, ":TITLE", $title);
oci_bind_by_name($parse, ":IMAGES", $lob_a, -1, OCI_B_BLOB);

json utf-8 encoding for android

i have some persian(utf8) words on my database for my android app and i am using json for show database information in android app.
I have following code on Databasemanager.php:
function getMusics()
{
$connection = mysqli_connect(DatabaseManager::HOST_NAME, DatabaseManager::USER_NAME, DatabaseManager::PASSWORD, DatabaseManager::DATABASE_NAME);
$sqlQuery = "SELECT * FROM musics where active = 1 order by date desc;";
$result = $connection->query($sqlQuery);
$musicsArray = array();
if ($result->num_rows > 0) {
for ($i = 0; $i < $result->num_rows; $i++) {
$musicsArray[$i] = $result->fetch_assoc();
}
}
echo json_encode($musicsArray);
}
and in GetMusic.php for get json information :
<?php
include "DatabaseManager.php";
$databaseManager = new DatabaseManager();
$databaseManager->getMusics();
but i have bellow jsons on output :
{"id":"3","name":"???","artist":"????? ????","like_count":"1","comment_count":"0","dl_link":null,"photo":"http:\/\/192.168.88.6\/musicarea\/photos\/3.jpg","active":"1","date":"2017-08-04 00:00:00"}
how can i solve it ??
on output(i just use persian language at 2 last rows):
on the app:
on php my admin:

You should set the default client charset to UTF-8. Use mysqli::set_charset OR mysqli_set_charset.
See http://de2.php.net/manual/en/mysqli.set-charset.php for more info.

You have to add the header that it tells the client the response is encoding with utf-8
header('Content-Type: text/html; charset=utf-8');

EDIT
function getMusics()
{
$connection = mysqli_connect(DatabaseManager::HOST_NAME, DatabaseManager::USER_NAME, DatabaseManager::PASSWORD, DatabaseManager::DATABASE_NAME);
$sqlQuery = "SELECT * FROM musics where active = 1 order by date desc;";
$result = $connection->query($sqlQuery);
$musicsArray = array();
if ($result->num_rows > 0) {
for ($i = 0; $i < $result->num_rows; $i++) {
$musicsArray[$i] = $result->fetch_assoc();
}
}
header("Content-type: application/json; charset=utf-8");
echo json_encode($musicsArray);
}

Streamed response from laravel to android

On our platform (based on Laravel 5.1) we provide audio and video content to registered users. The media files are stored outside the docroot of course.
So I use a method to provide the requested content. That works well on any browser and OS except Android (native or chrome). Android uses a byte range request for audio and video tags. The following code worked in the beginning and stopped working a while ago. I have no clue why. Any:
public function loadfile(Request $request, $type, $filename="")
{
$filepath = $mediadirectory . $filename;
if (File::isFile($filepath)) {
$file = File::get($filepath);
$mimetype = File::mimeType($filepath);
$size = File::size($filepath);
if ($mimetype=="audio/mpeg" || $mimetype=="video/mp4") {
$stream = fopen($filepath, "r");
$start = 0;
$length = $size;
$status = 200;
$headers = ['Content-Type' => $mimetype, 'Content-Length' => $size, 'Accept-Ranges' => 'bytes'];
if (false !== $range = $request->server('HTTP_RANGE', false)) {
list($param, $range) = explode('=', $range);
if (strtolower(trim($param)) !== 'bytes') {
header('HTTP/1.1 400 Invalid Request');
exit;
}
list($from, $to) = explode('-', $range);
if ($from === '') {
$end = $size - 1;
$start = $end - intval($from);
} elseif ($to === '') {
$start = intval($from);
$end = $size - 1;
} else {
$start = intval($from);
$end = intval($to);
}
$length = $end - $start + 1;
$status = 206;
$headers['Content-Range'] = sprintf('bytes %d-%d/%d', $start, $end, $size);
$headers['Connection'] = "keep-alive";
}
$response=new StreamedResponse(function() use ($stream, $start, $length) {
fseek($stream, $start, SEEK_SET);
echo fread($stream, $length);
fclose($stream);
}, $status, $headers);
return $response->send();
} else {
return response($file, 200)->header('Content-Type', $mimetype)->header('Content-Length', $size)->header('Content-Disposition', 'filename="' . $filename . '"');
}
}
}
The html is straight forward html5:
<audio controls preload="auto">
<source src="/loadfile/principiante.mp3" type="audio/mpeg">
</audio>

how to extract jsonarray in java when two arrays in output

How to retrieve the ids array from the following JSON Object.
{"bets":[{"bet":[{"gid":"10","Result":null}]},{"bet":[{"gid":"7","Result":null}]},{"bet":[{"gid":"3","Result":null},{"gid":"6","Result":"2"}]},{"bet":[{"gid":"6","Result":"2"},{"gid":"4","Result":"1"}]},{"bet":[{"gid":"6","Result":"2"},{"gid":"4","Result":"1"}]}]}{"ids":["9c9nogs6of","ank4kt3gqo","jfgrt91nk4","a8qmoq7v4q","8mov5ita1t"]}
I've tried
allids = jObj.getJSONArray("ids");
which should work because it works with jObj.getJSONArray("bets"); however I receive this error in logcat E/Buffer Error﹕ Error converting result org.json.JSONException: No value for ids
PHP FILE
<?php
// get tag
$param= $_POST['param'];
$bet = explode("//",$param);
$allbetslength = count($bet);
$ultresponse["bets"] = array();
$idresponse["ids"] = array();
for ($x = 0; $x < $allbetslength; $x++) {
$indid = substr($bet[$x],0,10);
array_push($idresponse["ids"], $indid);
$bet[$x] = substr($bet[$x],10);
$id = explode(",",$bet[$x]);
$arrlength = count($id);
// include db handler
require_once 'include/Check_Bets.php';
$db = new Check_Bets();
$response["bet"] = array();
for($y = 0; $y < $arrlength; $y++) {
$result= $db->checkuserbets($id[$y]);
array_push($response["bet"], $result);
}
array_push($ultresponse["bets"], $response);
array_push($ultresponse["bets"], $idresponse["ids"]);
}
echo json_encode($ultresponse);
?>
