[펌] Curl error 51: Cert veriy failed: UNITYTLS_X509VERIFY_FLAG_NOT_TRUSTED

First thing to do was to switch to Unity beta 2018.1. There you have the UnityWebRequest.certificateHandler This allows to set up custom certificate validation. one last thing to do is to create an object extending CertificateHandler to manage Certificate validation. (See here in Unity beta documentation)

Here is the code :

MyMonoBehaviour :

 IEnumerator GetRequest(string uri){
     UnityWebRequest request = UnityWebRequest.Get(uri);
     request.certificateHandler = new AcceptAllCertificatesSignedWithASpecificKeyPublicKey();
     yield return request.SendWebRequest ();
     if (request.isNetworkError)
     {
         Debug.Log("Something went wrong, and returned error: " + request.error);
     }
     else
     {
         // Show results as text
         Debug.Log(request.downloadHandler.text);
     }
 }

 

AcceptAllCertificatesSignedWithASpecificKeyPublicKey :

 using UnityEngine.Networking;
 using System.Security.Cryptography.X509Certificates;
 using UnityEngine;
 // Based on https://www.owasp.org/index.php/Certificate_and_Public_Key_Pinning#.Net
 class AcceptAllCertificatesSignedWithASpecificKeyPublicKey : CertificateHandler
 {
 
  // Encoded RSAPublicKey
  private static string PUB_KEY = "mypublickey";
  protected override bool ValidateCertificate(byte[] certificateData)
  {
     X509Certificate2 certificate = new X509Certificate2(certificateData);
     string pk = certificate.GetPublicKeyString();
     if (pk.ToLower().Equals(PUB_KEY.ToLower()))
         return true;
     return false;
  }
 }
