unity webgl获取页面Token信息，及加载StreamingAssets下.txt

接收JS端传回的token信息，如：

jwt~eyJhbGciOiJIUzI1NiIsIlR5cGUiOiJKd3QiLCJ0eXAiOiJKV1QifQ.eyJwYXNzd29yZCI6IjEyMzQ1NiIsImV4cCI6MTY0MjEzODIyNCwidXNlcm5hbWUiOiIxMTkwMjA1MTY5In0.ucdrtqfwOpaEzQkMHOWY7S_nvSTgOroRPa2T9y3H4q0

或者UserInf信息，如：

userinfo~{"id":111,"mobile":"18400000000","password":null,"photo":null,"qq":null,"sex":0,"sn":"100100100","username":"刘X","clazzId":null,"clazzNo":"2021122801","roleId":1,"createDate":"2021-12-29T09:21:58","updateDate":null,"creator":null,"updater":null}

在打包出来的web文件内找到index，做如下修改

 在打包出来的web文件内找到UnityProgress文件（路径：TemplateData/UnityProgress），做如下修改

if (progress == 1)
{
    gameInstance.logo.style.display = gameInstance.progress.style.display = "none";
  	getLocalStorage();
  }
 }   
    function getLocalStorage(){
        //读取localStorage,并调用函数传递信息到C#
        JSCommand('jwt~' + storage.getItem('jwt'));
        JSCommand('userinfo~' + storage.getItem('userinfo'));
    }
    //JS向C#传递信息
    function JSCommand(str) {
        console.log("JSCommand--" + str);
        //三个参数：第一个参数是脚本所在物体名，第二个是脚本函数名，第三个是发送信息
        gameInstance.SendMessage('MainScript', 'JSFunction', str);
    }
		

接下来在场景中创建对象（名字：MainScript（根据js的填写进行修改）） ，添加脚本（名字：MainSceneManager（可任意起）），脚本内方法如下：

//该方法通过页面端调用  接收webgl的js传递的信息

string sn = "";
string classid = "";
public void JSFunction(string str)
    {
        public void JSFunction(string str)
        {
            Debug.LogWarning("接收js传递信息");
            string[] tmpArray = str.Split('~');
            if (tmpArray[0] == "jwt")
            {
                token = tmpArray[1];
                Debug.LogWarning("token--" + token);
                //token--eyJhbGciOiJIUzI1NiIsIlR5cGUiOiJKd3QiLCJ0eXAiOiJKV1QifQ.eyJwYXNzd29yZCI6IjEyMzQ1NiIsImV4cCI6MTY0MjEzODIyNCwidXNlcm5hbWUiOiIxMTkwMjA1MTY5In0.ucdrtqfwOpaEzQkMHOWY7S_nvSTgOroRPa2T9y3H4q0
            }
            if (tmpArray[0] == "userinfo")
            {
                //转换接收到数据，进行处理
                JObject tmpObj = (JObject)JsonConvert.DeserializeObject(tmpArray[1]);
                //{"id":111,"mobile":"18400000000","password":null,"photo":null,"qq":null,"sex":0,"sn":"100100100","username":"刘X","clazzId":null,"clazzNo":"2021122801","roleId":1,"createDate":"2021-12-29T09:21:58","updateDate":null,"creator":null,"updater":null}
                userInf = tmpArray[1];
                sn = tmpObj["sn"].ToString();
                classid = (int)tmpObj["clazzId"];
            }
        }
    }
}

当在网页端启动inde.html时，调用上述方法。

当获取的userinfo信息含有数组时，如：

{"code":0,"msg":"查询班级","timestamp":"2022-01-14 03:30:29","data":[{"username":"张3","id":1,"name":"计算机","info":null,"teacherSn":null,"function1":0,"function2":1,"function3":1,"createDate":"2021-12-29T09:22:35","creator":null,"updateDate":null,"updater":null,"clazzNo":"2021122801"},{"username":"张4","id":2,"name":"计算机","info":null,"teacherSn":null,"function1":1,"function2":1,"function3":1,"createDate":"2021-12-29T09:22:35","creator":null,"updateDate":null,"updater":null,"clazzNo":"2021122802"},{"username":null,"id":3,"name":"计算机","info":"2323","teacherSn":null,"function1":1,"function2":0,"function3":0,"createDate":"2021-12-31T11:35:11","creator":null,"updateDate":null,"updater":null,"clazzNo":"202112280刘"}],"ttl":null,"count":3}

可使用下述（加载StreamingAssets下。。。）中的方法进行处理；

加载StreamingAssets下urlID.txt获取服务器地址，携带token和服务器交互，获取跟多信息，并进行处理；

 上述urlID.txt内地址需要自己修改成需要地址；

如何加载web端StreamingAssets下urlID.txt，调用Unity_Get请求（携带Token）以及对获取到包含数组的字符串处理如下：
