Question

我有一个asp.net网络服务和一个winforms应用程序。 winform应用程序调用Web服务的方法。

我在asp.net web服务asmx页面中的代码：

namespace ServicesTinhLuong
{
    public class ServicesTinhLuong : System.Web.Services.WebService
    {
        #region Login Webservice
        [WebMethod(Description = "Login Webservice")]

        public bool LogIn(string username, string password)
        {
            try
            {
                var usernameCF = WebConfigurationManager.AppSettings["LogInServiceUser"];
                var passCF = WebConfigurationManager.AppSettings["LogInServicePass"];
                passCF = new Common().EncPwd(passCF);
                var loginSuccess = (username == usernameCF) && (password == passCF);
                if (loginSuccess)
                {
                    FormsAuthentication.SetAuthCookie(username, true);
                    return true;
                }
                return false;
            }
            catch (Exception ex)
            {
                return false;
            }
        }

        [WebMethod(Description = "Logout Webservice")]
        [PrincipalPermission(SecurityAction.Demand, Authenticated = true)]
        public bool LogOut()
        {
            if (HttpContext.Current.User.Identity.IsAuthenticated)
                FormsAuthentication.SignOut();
            return true;
        }
        #endregion
        [WebMethod]
        [PrincipalPermission(SecurityAction.Demand, Authenticated = true)]
        public bool checkLogin(string username, string password)
        {
            try
            {
                SqlCommand command = new SqlCommand("CheckLogin", connection)
                {
                    CommandType = CommandType.StoredProcedure
                };
                command.Parameters.AddWithValue("@UserName", username);
                command.Parameters.AddWithValue("@Pass", password);

                if (connection.State == ConnectionState.Closed) connection.Open();
                DataTable dt = new DataTable();
                using (SqlDataAdapter adapter = new SqlDataAdapter(command))
                {
                    adapter.Fill(dt);
                    command.Dispose();
                }
                connection.Close();
                if (dt.Rows.Count > 0) return true;
                else return false;
            }
            catch (Exception ex)
            {
                return false;
            }
            }
      }
}

的web.config

<configuration>
  <connectionStrings>
    <add name="ServerName" connectionString="DUONG-PC" />
    <add name="DatabaseName" connectionString="TinhLuong" />
    <add name="UserID" connectionString="sa" />

    <modules>
      <remove name="ApplicationInsightsWebTracking"/>
      <add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" preCondition="managedHandler"/>
    </modules>
  </system.webServer>
</configuration>

我在winforms app中添加服务引用：

public ServicesTinhLuong.ServicesTinhLuongSoapClient service = new ServicesTinhLuong.ServicesTinhLuongSoapClient();

情形：当应用程序WinForms调用Web服务方法时，必须通过登录方法（字符串用户名，字符串密码）登录，成功登录Web服务后才能存储cookie。然后WinForms应用程序可以调用其他Web服务方法，而无需通过登录方法再次登录

在Web服务中进行身份验证有很多方法可以使用行为等等.... 但有一些链接，惠特样本会帮助你

我建议你转发链接

如果您的会话死亡用户需要登录
