我是 Kotlin 和协程的新手。我fun在我的活动和里面有一个，检查User用户名和密码，如果是真的，返回Users对象。
一切都好。但是当我按下按钮时，我的活动被阻止并等待Users登录响应。
我用这个乐趣：

private fun checkLogin() : Boolean {           
        runBlocking {
            coroutineScope {
                launch {
                    user = viewModel.getUserAsync(login_username.text.toString(), login_password.text.toString()).await()
                }
            }
            if(user == null){
                return@runBlocking false
            }
            return@runBlocking true
        }
        return false
    }  

这是我的 ViewModel ：

class LoginViewModel(app: Application) : AndroidViewModel(app) {
    val context: Context = app.applicationContext
    private val userService = UsersService(context)

    fun getUserAsync(username: String, password: String) = GlobalScope.async {
        userService.checkLogin(username, password)
    }
}

用户服务：

class UsersService(ctx: Context) : IUsersService …

我尝试连接到Binance ApiUsing C#And RestSharplib。根据文件，我应该尝试这样的事情：

查询字符串：符号=LTCBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000×tamp=1499827319559

我尝试了很多方法和很多堆栈问题，但我找到了其他语言而不是 c# 的解决方案。这是我所做的基于：这个和这个

public string GetAccountInfo()
    {
        long timeStamp = GetTimestamp();
        var request = new RestRequest("api/v3/account");
        request.AddHeader("X-MBX-APIKEY", ApiKey);
        request.AddParameter("timestamp", timeStamp, ParameterType.QueryString);
        request.AddParameter("recvWindow", RecvWindow, ParameterType.QueryString);
        request.AddParameter("signature", GetSignature(request.Parameters), ParameterType.QueryString);
        return Client.Get(request).Content;
    }
private long GetTimestamp()
    {
        return new DateTimeOffset(DateTime.UtcNow).ToUnixTimeMilliseconds();
    }

    private string …
