Unity webGL interacts with js (get address bar URL)

1. Unity pass value to js

in unity:

 void Awake()
    {
        Application.ExternalCall("GetCookie");//GetCookie参数是js方法名字
    }

js:

 function GetCookie() {
          //var result = document.URL;//获取地址
          var result = document.location.href;//获取地址
          if (result != "") {
              var result = decodeURIComponent(result);
          }
		  console.log("发送消息：Cookie，OnCookie_Callback");
          unityInstance.SendMessage("Cookie", "OnCookie_Callback", result);
      }

2. js pass value to unity

Parameter 1 Cookie: the name of the object in the scene (the name of the uppermost parent object, otherwise the value cannot be passed successfully)
Parameter 2 OnCookie_Callback: method name
Parameter 3 result: value

unityInstance.SendMessage("Cookie","OnCookie_Callback",result);

in unity:

 public void OnCookie_Callback(string cookie)
    {
        Debug.Log("收到cookie=" + cookie);
        
    }

whole:

The name of the object in the unity scene

Untiy code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Test : MonoBehaviour
{
    private string NextSceneName;

    void Awake()
    {
        Application.ExternalCall("GetCookie");//GetCookie参数是js方法名字
    }

    public void OnCookie_Callback(string cookie)
    {
        Debug.Log("收到cookie=" + cookie);
        
    }
}

js code:

<!DOCTYPE html>
<html lang="en-us">
  <head>
    <meta charset="utf-8">
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">

      var unityInstance = UnityLoader.instantiate("unityContainer", "Build/Test99.json", {onProgress: UnityProgress});
	  
	 function GetCookie() {
          var result = document.URL;//获取地址
         // var result = document.location.href;//获取地址
		  console.log("发送消息：Cookie，OnCookie_Callback");
          gameInstance.SendMessage("Cookie", "OnCookie_Callback", result);
      }
    </script>
  </head>

    <div class="webgl-content">
