通过PHP [CodenameOne]在服务器上上传文件

Question

I want to upload image file on server, because not found any way to upload file directly on server from CodenameOne. I convert image in Base64 format and send to php file then in php again decode image and tried to upload. But same also not working. Can you please tell me how do i solve this problem ?

My PHP Code :

<?php

define('UPLOAD_DIR', 'public_html/appFiles/GKQuiz/userProfilePicture/');
//$Imagecode=$_POST['Image'];


//Base64 String already added in $Imagecode
$Imagecode="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";

Answer 1

Finally the found answer for same as below.

Corrected PHP Code :

<?php

define('UPLOAD_DIR',$_SERVER['DOCUMENT_ROOT'].'/appFiles/GKQuiz/userProfilePicture/');

// after $_SERVER['DOCUMENT_ROOT']. your root inside public_html folder if any or '/'.

$Imagecode=$_POST['Image']; // parameter

$img=base64_decode($Imagecode);
$uid=uniqid();

$file = UPLOAD_DIR . $uid . '.jpg';
$success = file_put_contents($file, $img);

if ($success)
{
  echo $uid.'.jpg';
}
else
{
  echo "error";
}

?>

In CodenameOne your code may be as below :

if (profilepic!=null) {
ImageIO imgIO = ImageIO.getImageIO();
ByteArrayOutputStream out = new ByteArrayOutputStream();
imgIO.save(profilepic, out, ImageIO.FORMAT_JPEG, 1);
byte[] ba = out.toByteArray();
String Imagecode = Base64.encode(ba);
//System.out.println("data :"+Imagecode);
request = new ConnectionRequest(){
     @Override
     protected void handleErrorResponseCode(int code, String message) {
           System.out.println("Code :"+code+" Msg :"+message);
     }

};
request.setPost(true);
request.setHttpMethod("POST");
request.addArgument("Image", Imagecode);
request.setUrl("http://example.com/filename.php");
NetworkManager.getInstance().addToQueueAndWait(request);
}else{
     System.out.println("Unable to upload");
}
