Decoding HTML Entities

Hello,

I've been searching for a while now on how to decode HTML entities. I was originally using System.Web.dll using the HTTPUtility. However, I've now discovered this can't be used on Android (the build always fails)

I've since tried searching for another way to accomplish this within Unity. I moved from using 'WWW' to 'UnityWebRequest' to see if there were any methods that I could use. However, still no joy. I've tried setting the request headers to 'text/plain' but I still can't get it to work. Please see the code below...

Code (CSharp):

1.         url = "https://opentdb.com/api.php?amount=" + 10 + "&difficulty=medium&category=31";
2.         test = new UnityWebRequest(url);
3.         test.downloadHandler = new DownloadHandlerBuffer();
4.         test.SetRequestHeader("Content-Type", "text/plain");
5.         yield return test.SendWebRequest();
6.  
7.         if(test.isNetworkError || test.isHttpError)
8.         {
9.             Debug.Log(test.error);
10.         } else
11.         {
12.             Debug.Log(test.GetRequestHeader("Content-Type"));
13.             Debug.Log(test.downloadHandler.text);
14.         }

Here you can see the &quot is not being decoded...

Does anyone know of a way I can do this and still build my game for Android?

Thanks

 

It might be helpful to know what the error on android was.

 

There was no error on Android? As mentioned in my first post, the build fails saying that System.Web.dll is 'not allowed'

 

https://docs.unity3d.com/ScriptReference/WWW.UnEscapeURL.html
Maybe try this?

 

I could have sworn I tried this before...oh well, seems to be working now! Thank you!

 

Update: Turns out it didn't work, I am sorry to say.

I'll paste what I have below.

Code (CSharp):

1.         jsonData = JsonMapper.ToObject(WWW.UnEscapeURL(www.text));
2.         Debug.Log("Json Mapper...");
3.         Debug.Log(WWW.UnEscapeURL(www.text));

www.text still contains HTML entities.

 

System.Net.WebUtility is in .net Standard 2.0, so I think it should be usable in Unity 2018.1

See https://blogs.unity3d.com/2018/03/2...me-in-unity-2018-1-what-does-the-future-hold/
And https://docs.microsoft.com/en-ca/dotnet/api/system.net.webutility?view=netstandard-2.0

 

Have you tried the WebUtility.HtmlDecode(string)?

 

Hey, thanks for the replies both of you.

Looks like Brathnann's solution worked. I've heard of the WebUtility before but I was looking for 'HttpUtility.HtmlDecode' which Unity didn't seem to have.

Well, looks like its all sorted now. I just tried to export to Android, did an install and seems to be working just fine. Thanks all!
