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
<script>
var gameInstance = UnityLoader.instantiate("gameContainer", "Build/TestDiaoYong2.json", {onProgress: UnityProgress});
if(!window.localStorage)
{
alert("浏览器不支持localstorage");
}
else
{
//写入localStorage
var storage=window.localStorage;
}
</script> 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：

int classid;
int func1;

int func3;
string url_login = ""; //获取Get请求地址
string url_score = ""; //上传数据地址
void Start()
{
System.TimeSpan st = System.DateTime.UtcNow - new System.DateTime(1970, 1, 1, 0, 0, 0);//获取时间戳Debug.Log(Convert.ToInt64(st.TotalSeconds) );//时间戳转换Int64
timeStamp = Convert.ToInt64(st.TotalMinutes);
}
// 接收webgl的js传递的信息
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);
Data.token = token;
}
if (tmpArray[0] == "userinfo")
{
JObject tmpObj = (JObject)JsonConvert.DeserializeObject(tmpArray[1]);
sn = tmpObj["sn"].ToString();
classid = (int)tmpObj["clazzNo"];
StartCoroutine(Get_UrlData());
}
}
//通过urlID.txt 查找地址
IEnumerator Get_UrlData()
{
Debug.Log("加载streamingAssets下urlID.txt");
var uri = new System.Uri(Path.Combine(Application.streamingAssetsPath, "urlID.txt"));
UnityWebRequest www = UnityWebRequest.Get(uri);
yield return www.SendWebRequest();
if (www.isNetworkError || www.isHttpError)
{
Debug.Log(www.error);
}
else
{
Debug.Log(www.downloadHandler.text);
string jsonStr = www.downloadHandler.text;
TestData testData = JsonUtility.FromJson<TestData>(jsonStr);
url_login = testData.url_login;
url_score = testData.url_score;
StartCoroutine(Get_AllData());
}
}
//通过token 查找信息
IEnumerator Get_AllData()
{
UnityWebRequest www = UnityWebRequest.Get(Data.url_login);
www.SetRequestHeader("admin-token", Data.token);
yield return www.SendWebRequest();
if (www.isNetworkError || www.isHttpError)
{
Debug.Log(www.error);
}
else
{
Debug.Log(www.downloadHandler.text);
//返回数据string转json对象
JObject tmpObj = (JObject)JsonConvert.DeserializeObject(www.downloadHandler.text);
JArray jArray = (JArray)tmpObj["data"];
Debug.Log("jArray.Count--" + jArray.Count);
for (var i = 0; i < jArray.Count; i++)
{
JObject jo2 = (JObject)jArray[i];
if ((int)(jo2["clazzNo"]) == classid)
{
func1 = Convert.ToInt32(jo2["function1"]);
func2 = Convert.ToInt32(jo2["function2"]);
func3 = Convert.ToInt32(jo2["function3"]);
}
}
}
}
