[游戏开发]【Unity项目】登录界面

数据库

登录时验证用户名和密码，使用MySQL数据库管理数据，类中的主要方法也都是使用SQL语句完成。类中还提供两个接口， 一个通过username获取UserInfo ，一个是直接获取到排行榜。
数据库连接类

    //数据库名称
    private static string databaseName;
    public MySqlAccess(string _host,string _port, string _username, string _password, string _databaseName)
    {
        host = _host;
        port = _port;
        username = _username;
        password = _password;
        databaseName = _databaseName;
        OpenSql();
    }
    private void OpenSql()
    {
        try {
            string mySqlString = string.Format("datasource={0};port={1};database={2};user={3};pwd={4};"
                , host, port, databaseName, username, password);
            //Debug.Log(mySqlString);
            mySqlConnection = new MySqlConnection(mySqlString);
            mySqlConnection.Open();
        } catch (Exception e) {
            throw new Exception("服务器连接失败，请重新检查MySql服务是否打开。" + e.Message);
        }
    }
