Upload images on server

Hi,

I need to take jpg or png screenshots at time intervals and store it on the file system and on a server; with this code I solved the file system saving:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 using System.IO;
 
 public class ScreenRecorder : MonoBehaviour {
     public int framerate = 30;
     public bool JPGImage = true;
     public int superSize;
 
     int frameCount = 0;
     bool recording = false;
     int ImageCounter = 0;
     int TimeCounter = 0;
     string imageFileDir = "";
 
     void Start () {
         imageFileDir = Application.persistentDataPath+"/Capture/";
         frameCount = 0;
     }
 
     public void StartStopRecording () {
         GameObject StartStopButtonGO;
 
         StartStopButtonGO = GameObject.Find ("RecText");
 
         if (!recording) {
             ImageCounter = 0;
             SetImageCounter (ImageCounter);
             SetTimeCounter (TimeCounter);
             DeleteImageDir (imageFileDir);
         }
 
         recording = !recording;
         if (recording) {
             Time.captureFramerate = framerate;
             frameCount = -1;
             StartStopButtonGO.GetComponent<Text>().text = "STOP";
             Debug.Log ("Start recording");
         } else {
             StartStopButtonGO.GetComponent<Text>().text = "REC";
             Debug.Log ("Stop recording");
         }
     }
 
     void Update () {
         StartCoroutine(TakeShoot ());
     }
 
     void SetImageCounter (int ImageCount) {
         GameObject ImageCounterGO;
 
         ImageCounterGO = GameObject.Find ("ImageCount");
         ImageCounterGO.GetComponent<Text> ().text = ImageCount.ToString ();
     }
 
     void SetTimeCounter (int TimeCount) {
         GameObject TimeCounterGO;
 
         TimeCounterGO = GameObject.Find ("TimeCount");
         TimeCounterGO.GetComponent<Text> ().text = TimeCount.ToString ();
     }
 
     IEnumerator TakeShoot() {
         byte[] bytes;
         string fullImageFileName = imageFileDir + "/";
         string imageName = "frame";
 
         if (recording) {
             if (frameCount > 0 && frameCount % 30 == 0) {
 
                 yield return new WaitForEndOfFrame ();
 
                 // Create a texture the size of the screen, RGB24 format
                 int width = Screen.width;
                 int height = Screen.height - 100; // Screen.height-button height
 
                 Texture2D tex = new Texture2D (width, height, TextureFormat.RGB24, false);
 
                 // Read screen contents into the texture
                 tex.ReadPixels (new Rect (0, 100, width, height), 0, 0);
                 tex.Apply ();
 
                 imageName = "frame" + frameCount.ToString ("0000");
 
                 if (JPGImage) {
                     bytes = tex.EncodeToJPG (100);
                     imageName += ".jpg";
                 } else {
                     bytes = tex.EncodeToPNG ();
                     imageName += ".png";
                 }
 
                 fullImageFileName += imageName;
                 Destroy (tex);
 
                 File.WriteAllBytes (fullImageFileName, bytes);
 
                 ImageCounter++;
                 SetImageCounter (ImageCounter);
 
                 yield return null;
             }
             frameCount++;
 
             if (frameCount % 60 == 0) {
                 TimeCounter++;
                 SetTimeCounter (TimeCounter);
             }
         }
     }
 
     void DeleteImageDir(string ImagePath) {
         if (Directory.Exists (ImagePath)) {
             var OldImageFiles = Directory.GetFiles(ImagePath);
             for (int i = 0; i < OldImageFiles.Length; i++)
                 File.Delete (OldImageFiles [i]);
         } else {
             Directory.CreateDirectory (ImagePath);
         }
     }
 }

 

Now I'm trying to upload images on a server and I found this examples:

https://docs.unity3d.com/ScriptReference/WWWForm.html

but what about the PERL script "http://www.my-server.com/cgi-bin/screenshot.pl"?

Or this: https://docs.unity3d.com/ScriptReference/WaitForEndOfFrame.html

but what about the CGI script "WWW w = new WWW("http://localhost/cgi-bin/env.cgi?post", form);"?

So, there is a way to load an image or, in general, a file on a server?

Thank you!

[EDIT] Finally I found these examples:

https://msdn.microsoft.com/en-us/library/system.net.ftpwebrequest(v=vs.110).aspx https://www.codeproject.com/Tips/443588/Simple-Csharp-FTP-Class

This way I can upload files but I need also to show the upload progress; in the second example I can add

Debug.Log (string.Format("Progress: {0}", ((100*localFileStream.Position) / localFileStream.Length)));

in requestStream.Write cycle but the upload process stucks the app so messages are written only at the end of the entire upload process.

Some idea?

Thank you
