準備工作
網(wǎng)站建設(shè)哪家好,找創(chuàng)新互聯(lián)建站!專注于網(wǎng)頁設(shè)計、網(wǎng)站建設(shè)、微信開發(fā)、小程序制作、集團企業(yè)網(wǎng)站建設(shè)等服務(wù)項目。為回饋新老客戶創(chuàng)新互聯(lián)還提供了橋東免費建站歡迎大家使用!
一個接口一個類(數(shù)據(jù)庫管理類)
public interface DBInterface { IDbConnection GetConnection(); IEnumerableQuery (string sql, object param = null, IDbTransaction transaction = null, bool buffered = true, int? commandTimeout = null, CommandType? commandType = null); int Execute(string sql, object param = null, IDbTransaction transaction = null, int? commandTimeout = null, CommandType? commandType = null); }
public class DB:DBInterface { IDbConnection _dbConnection; public DB(IDbConnection dbConnection, string connectionString) { _dbConnection = dbConnection; _dbConnection.ConnectionString = connectionString; } ////// 連接對象 /// ///public IDbConnection GetConnection() { return _dbConnection; } /// /// 查詢方法 /// ///映射實體類 /// sql語句 /// 參數(shù)對象 /// 事務(wù) /// 是否緩存結(jié)果 /// command超時時間(秒) /// command類型 ///public IEnumerable Query (string sql, object param = null, IDbTransaction transaction = null, bool buffered = true, int? commandTimeout = null, CommandType? commandType = null) { return _dbConnection.Query (sql, param, transaction, buffered, commandTimeout, commandType); } /// /// 執(zhí)行方法 /// /// 映射實體類 /// 參數(shù)對象 /// 事務(wù) /// command超時時間(秒) /// command類型 ///public int Execute(string sql, object param = null, IDbTransaction transaction = null, int? commandTimeout = null, CommandType? commandType = null) { return _dbConnection.Execute(sql, param, transaction, commandTimeout, commandType); } }
數(shù)據(jù)庫管理接口和類都已經(jīng)準備好,接下來就是注入進去才能進行使用
//sqlite連接字符串 var connectionString = string.Format("Data Source={0}/db.sqlite", System.IO.Directory.GetCurrentDirectory()); //將數(shù)據(jù)庫連接字符串注入進去 services.AddSingleton(connectionString); //sqlieconnection注放 services.AddScoped(); //注放數(shù)據(jù)庫 services.AddScoped ();
使用
用戶實體類
////// 用戶實體類 /// public class User { ////// ID /// public int ID { get; set; } ////// 用戶名 /// public string UserName { get; set; } ////// 密碼 /// public string Password { get; set; } public Int64 Phone { get; set; } ////// 用戶名稱 /// public string Name { get; set; } ////// 角色ID /// public int RoleID { get; set; } ////// 部門編號 /// public int DepartmentID { get; set; } }
用戶管理接口
public interface IUserRepository { ////// 登錄 /// /// 用戶名 /// 密碼 ///UserRole Login(string userName, string password); }
用戶管理接口實現(xiàn)
public class UserRepository : IUserRepository { ////// 數(shù)據(jù)庫對象 /// DBInterface _db; public UserRepository(DBInterface db) { _db= db; } ////// 登錄 /// /// 用戶名 /// 密碼 ///public UserRole Login(string userName, string password) { string sql = "select " + "users.*,roles.rolename " + "from users join roles on users.roleid=roles.id " + "where username=@username and password=@password"; var userRole = _db.Query (sql, new { username = userName, password = password }).SingleOrDefault(); if (userRole == null) { throw new Exception("用戶名或密碼錯誤!"); } else { return userRole; } } }
控制器中使用
////// 登錄接口 /// /// /// /// /////[HttpPost] public IActionResult Login(string userName, string password) { try { var userRole = _userRepository.Login(userName, password); var BuildToken = Token.BuildToken( new Dictionary { { "userid", userRole.ID }, { "username", userRole.Name }, { "phone", userRole.Phone } }); HttpContext.Session.SetString("token", BuildToken); return backFun.success(Msg: "登錄成功", Data: new { token = BuildToken,userId= userRole.ID,userInfo= userRole }); } catch (Exception ex) { return backFun.error(Msg: ex.Message); } }
寫到這里基本上跟都已經(jīng)搞定,雖然有些不完善,但是asp.net cor和dapper的接口使用流程與方法做了簡單的使用和介紹,不完善的地方需要留給您來完善,不完整的地方需要你自己去完整他,不動腦怎么成長,不動手怎么去驗證劉成剛是否正確。
