我有多个asp.net网络表单和sql express数据库。 在Web表单中,需要从菜单中控制3种类型的操作
ADD, DELETE , EDIT.
我要创建自定义用户角色,以指定用户权限来管理对用户的访问控制 asp.net c#应用 (菜单,添加,删除和编辑可见性。)
目前,我正在尝试在每个页面上针对每个按钮和链接使用简单的SQL阅读器查询。
string yes = "1";
if (rdr["access"].ToString() == yes.ToString())
Button1.Visible = true;
答案 0 :(得分:0)
您将需要以下SQL表:
CREATE TABLE Roles
(
Rolename Text (255) NOT NULL,
ApplicationName Text (255) NOT NULL,
CONSTRAINT PKRoles PRIMARY KEY (Rolename, ApplicationName)
)
CREATE TABLE UsersInRoles
(
Username Text (255) NOT NULL,
Rolename Text (255) NOT NULL,
ApplicationName Text (255) NOT NULL,
CONSTRAINT PKUsersInRoles PRIMARY KEY (Username, Rolename, ApplicationName)
)
然后构建角色提供程序类
您可以使用EF或ADO.NET来实现方法
public class SqlRoleProvider: RoleProvider
{
public override void Initialize(string name, NameValueCollection config)
{
//
// Initialize values from web.config.
//
}
public override void AddUsersToRoles(string[] usernames, string[] rolenames)
{
}
public override void CreateRole(string rolename)
{
}
public override bool DeleteRole(string rolename, bool throwOnPopulatedRole)
{
}
public override string[] GetAllRoles()
{
}
public override string[] GetRolesForUser(string username)
{
}
public override string[] GetUsersInRole(string rolename)
{
}
public override bool IsUserInRole(string username, string rolename)
{
}
public override void RemoveUsersFromRoles(string[] usernames, string[] rolenames)
{
}
public override bool RoleExists(string rolename)
{
}
public override string[] FindUsersInRole(string rolename, string usernameToMatch)
{
}
}
您必须在web.config中进行设置
<configuration>
<connectionStrings>
<add name="SqlServices" connectionString="DSN=RolesDSN;" />
</connectionStrings>
<system.web>
<authentication mode="Forms" />
<forms loginUrl="loginvb.aspx"
name=".ASPXFORMSAUTH" />
</authentication>
<authorization>
<deny users="?" />
</authorization>
<roleManager defaultProvider="SqlRoleProvider"
enabled="true"
cacheRolesInCookie="true"
cookieName=".ASPROLES"
cookieTimeout="30"
cookiePath="/"
cookieRequireSSL="false"
cookieSlidingExpiration="true"
cookieProtection="All" >
<providers>
<clear />
<add
name="SqlRoleProvider"
type="Samples.AspNet.Roles.SqlRoleProvider"
connectionStringName="SqlServices"
applicationName="SampleApplication"
writeExceptionsToEventLog="false" />
</providers>
</roleManager>
</system.web>
</configuration>
Microsoft提供了示例角色提供程序:

用于OLEDB(访问数据库)的示例实现,您可以使用SqlConnection,SqlCommand,SqlDataReader ...将实现更改为使用SQL数据库。
