unity webGL与js 交互（获取地址栏URL）

1.unity传值给js

unity中：

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

js中：

 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传值给unity

参数一 Cookie：场景中物体的名称（最上层父物体名字，否则无法成功传值）
参数二 OnCookie_Callback：方法名称
参数三 result：值

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

unity中:

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

完整：

unity场景中物体的名称

untiy代码：

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);
        
    }
}
