warning

Note: You do not need to manually convert to a JSON string; simply pass an object parameter, and it will be automatically converted internally.

2.Create your unity script​

You need to create a script that implements the IEdgeMessageReceived interface and attach it to the same GameObject as EdgeCanvas!!!

danger

If it is not the same GameObject, the message cannot be received.

using UnityEngine;

public class ReceiveWebMessage : MonoBehaviour, IEdgeMessageReceived
{
    public void OnMessageReceived(string msg)
    {
        Debug.Log(msg);
    }
}
