GET image over HTTPS with unvalidated SSL certificate and authenication
I have a Raspberry Pi server where if I request GET https://192.168.1.2/stream, the server will ask for authentication, then provide a snapshot image of the webcam. I use HttpWebRequest for authentication and to allow all SSL certificates (also, there's HttpWebResponse which pairs with it), but UnityWebRequest is good at requesting an image. How would I combine the both into one request? Should I use HttpWebRequest or UnityWebRequest? (I don't use WWW and WWWForm for inability to ignore SSL errors, or allow all SSL certificates).
In one request, I need to:
Ignore SSL errors, or accept all SSL certificates
Authenticate my identity with username and password
Receive an image texture
I'm basically looking for the 'One Class to Rule Them All'
Thank you!
using UnityEngine; // Main stuff
using UnityEngine.UI; // For 'urlInput'
using UnityEngine.Networking; // For 'UnityWebRequest'
using System.Collections; // Main stuff
using System.Net; // Main Network library, most important
using System.Net.Security; // For 'SslPolicyErrors'
using System.Security.Cryptography.X509Certificates; // For building the trusted certificates list
public class Stream_HTTPS : MonoBehaviour {
public InputField urlInput; // Format: 0.0.0.0
private string url;
public float GetRate = 0.15f;
private float nextGet = 0;
IEnumerator GetTexture() {
url = urlInput.text;
Renderer renderer = GetComponent<Renderer>();
ServicePointManager.ServerCertificateValidationCallback = TrustCertificate;
// ===============
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://" + url + "/stream");
request.ContentType = "image/jpg";
request.PreAuthenticate = true;
request.Credentials = new NetworkCredential ("Robot","password123");
request.Method = "GET";
// ^^^
// Combine
// vvv
UnityWebRequest www = UnityWebRequest.GetTexture ("http://" + url + "/stream");
yield return www.Send();
renderer.material.mainTexture = ((DownloadHandlerTexture)www.downloadHandler).texture;
// ===============
}
void Update() {
if (Time.time > nextGet) {
StartCoroutine (GetTexture ());
nextGet = Time.time + GetRate;
}
}
private static bool TrustCertificate(object sender, X509Certificate x509Certificate, X509Chain x509Chain, SslPolicyErrors sslPolicyErrors) {
// Accept all Certificates
return true;
}
}
As Dreamora says here: `HttpWebRequest` does not load sounds or textures. What should I do? Is there any other class which supports texture load along with ignoring SSL errors and authentication?
