UnityWebGL获取网页地址中的Token值

与网页端具体的交互参考我的例外一篇博客：

Unity版本：Unity2021.2.15f1

.jslib的代码内容:

mergeInto(LibraryManager.library, {
          
   
    GetToken: function () {
          
   
        var url = window.location.href;

        var temp = url.split(?)[1];
        var pram = new URLSearchParams(? + temp);
        var tookenStr = pram.get(token);

        var bufferSize = lengthBytesUTF8(tookenStr) + 1;
        var buffer = _malloc(bufferSize);
        stringToUTF8(tookenStr, buffer, bufferSize);
        return buffer;
    },
});

注意：代码中添加注释会打包报错，打包的文件夹会缺少文件，具体是什么原因，我也不清楚。 报错内容：Building LibraryBeeartifactsWebGLuilddebug_WebGL_wasmuild.js failed with output:

C#代码

using System.Runtime.InteropServices;
using UnityEngine;

public class NewBehaviourScript : MonoBehaviour
{
          
   
    [DllImport("__Internal")]
    private static extern string GetToken();
    
    void Start()
    {
          
   
        string str = GetToken();
        Debug.Log("unity得到的token值: " + str);
    }

}
