Helper class to generate form data to post to web servers using the UnityWebRequest or WWW classes.

using UnityEngine;
using UnityEngine.Networking;
using System.Collections;

public class WWWFormImage : MonoBehaviour {

public string screenShotURL= "http://www.my-server.com/cgi-bin/screenshot.pl";

// Use this for initialization void Start() { StartCoroutine(UploadPNG()); }

IEnumerator UploadPNG() { // We should only read the screen after all rendering is complete yield return new WaitForEndOfFrame();

// Create a texture the size of the screen, RGB24 format int width = Screen.width; int height = Screen.height; var tex = new Texture2D( width, height, TextureFormat.RGB24, false );

// Read screen contents into the texture tex.ReadPixels( new Rect(0, 0, width, height), 0, 0 ); tex.Apply();

// Encode texture into PNG byte[] bytes = tex.EncodeToPNG(); Destroy( tex );

// Create a Web Form WWWForm form = new WWWForm(); form.AddField("frameCount", Time.frameCount.ToString()); form.AddBinaryData("fileUpload", bytes, "screenShot.png", "image/png");

// Upload to a cgi script using (var w = UnityWebRequest.Post(screenShotURL, form)) { yield return w.SendWebRequest(); if (w.result != UnityWebRequest.Result.Success) { print(w.error); } else { print("Finished Uploading Screenshot"); } } } }

Here is a sample script that retrieves the high scores stored in a table in an SQL database.

using UnityEngine;
using UnityEngine.Networking;
using System.Collections;

public class WWWFormScore : MonoBehaviour { string highscore_url = "http://www.my-site.com/highscores.pl"; string playName = "Player 1"; int score = -1;

// Use this for initialization IEnumerator Start() { // Create a form object for sending high score data to the server WWWForm form = new WWWForm();

// Assuming the perl script manages high scores for different games form.AddField( "game", "MyGameName" );

// The name of the player submitting the scores form.AddField( "playerName", playName );

// The score form.AddField( "score", score );

// Create a download object var download = UnityWebRequest.Post(highscore_url, form);

// Wait until the download is done yield return download.SendWebRequest();

if (download.result != UnityWebRequest.Result.Success) { print( "Error downloading: " + download.error ); } else { // show the highscores Debug.Log(download.downloadHandler.text); } } }

Here is a sample Perl script that processes the high scores stored in a table in an SQL database.

# The SQL database needs to have a table called highscores
# that looks something like this:
#   CREATE TABLE highscores (
#     game varchar(255) NOT NULL,
#     player varchar(255) NOT NULL,
#     score integer NOT NULL
#   );
use strict;
use CGI;
use DBI;

# Read form data etc. my $cgi = new CGI;

# The results from the high score script will be in plain text print $cgi->header("text/plain");

my $game = $cgi->param('game'); my $playerName = $cgi->param('playerName'); my $score = $cgi->param('score');

exit 0 unless $game; # This parameter is required

# Connect to a database my $dbh = DBI->connect( 'DBI:mysql:databasename', 'username', 'password' ) || die "Could not connect to database: $DBI::errstr";

# Insert the player score if there are any if( $playerName && $score) { $dbh->do( "insert into highscores (game, player, score) values(?,?,?)", undef, $game, $playerName, $score ); }

# Fetch the high scores my $sth = $dbh->prepare( 'SELECT player, score FROM highscores WHERE game=? ORDER BY score desc LIMIT 10' ); $sth->execute($game); while (my $r = $sth->fetchrow_arrayref) { print join(':',@$r),"\n" }


data(Read Only) The raw data to pass as the POST request body when sending the form.
headers(Read Only) Returns the correct request headers for posting the form using the WWW class.
