[SOLVED] WebGL Build problem with WebRequest RequestStream

We are having a problem with a web request. This script is working just fine when build for Android, but when compiling it for WebGL its freezing on the browser. Applying some debugging to console we found that the problem is in the line marked in between # but we can't seem to find an answer of what might be happening.
ATM we will try to use this way now https://docs.unity3d.com/Manual/UnityWebRequest-SendingForm.html and hope that fix it.

Code (CSharp):

1.  
2. LoginInfo newLogin = new LoginInfo(_usuario);
3.         bool succesful = false;
4.  
5.         if (currentLogin.user != newLogin.user || (currentLogin.user == newLogin.user && !currentLogin.isLoggedIn))
6.         {
7.             Debug.Log("Set Request");
8.             httpVerb httpMethod = httpVerb.POST;
9.  
10.             string strResponseValue = string.Empty;
11.  
12.             string postData = "email=" + usuario + "&password=" + password;
13.             //string postData = "";
14.             ASCIIEncoding encoding = new ASCIIEncoding();
15.             byte[] byte1 = encoding.GetBytes(postData);
16.  
17.             //Set the content type of the data being posted.
18.  
19.  
20.             //Set the content length of the string being posted.
21.             Debug.Log("Accept all certifications");
22.             ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications);
23.  
24.             Debug.Log("Create WebRequest");
25.             HttpWebRequest request = (HttpWebRequest)WebRequest.Create("URL URL URL :P");
26.  
27.             request.Method = httpMethod.ToString();
28. request.ContentType = "application/x-www-form-urlencoded";
29.             request.ContentLength = byte1.Length;
30.  
31. //########The problem is in this line###########
32.             Stream newStream = request.GetRequestStream();
33. //########################################
34.             newStream.Write(byte1, 0, byte1.Length);
35.  
36.             newStream.Close();
37.  
38. //After this we just get the response
39.  

 

It was solved by using this method https://docs.unity3d.com/Manual/UnityWebRequest-SendingForm.html for http comunication, HttpWebRequest seems to bring a few issues on WebGL.

 

I'm using exactly that but I can't get it to work in WebGL. Works fine in the editor though.
I can't get any returned data in WebGL.
Any hints please?

 

It looks like you are using System.Net.HttpWebRequest, that non-functional on WebGL platforom according to this page https://docs.unity3d.com/Manual/webgl-networking.html

So you might end up using UnityWebRequest instead of HttpWebRequest

 

for webGL build You can also make the request by javascript and then call the unity public function you need:

"gameInstance.SendMessage(<YourGameObject>, <ThePublicFunctionYouWantToCallInAScriptInYourGameObject>, <parameters>)
