MVC3 AuthorizeAttribute

这允许“frankl”访问但阻止管理员。我做错了什么?

 [Authorize(Order=1,Roles = "Admin",Users="frankl")]
public class AuthorizeBaseController_Admins_frank : Controller
{

}

这可能很简单,但我没有看到任何结合两者的例子,当我尝试添加它时,“Allowmultiple”属性会产生错误。

谢谢, 克里斯

角色和用户应该专门使用。如果要组合它们,可以编写自定义授权属性:

public class MyAuthoirizeAttribute : AuthorizeAttribute
{
    protected override bool AuthorizeCore(HttpContextBase httpContext)
    {
        if (httpContext == null)
        {
            throw new ArgumentNullException("httpContext");
        }
        var user = httpContext.User;
        if (!user.Identity.IsAuthenticated)
        {
            return false;
        }
        var usersSplit = SplitString(Users);
        var rolesSplit = SplitString(Roles);

        return
            (usersSplit.Length > 0 && usersSplit.Contains(user.Identity.Name, StringComparer.OrdinalIgnoreCase)) ||
            (rolesSplit.Length > 0 && rolesSplit.Any(user.IsInRole));
    }

    private string[] SplitString(string original)
    {
        if (string.IsNullOrEmpty(original))
        {
            return new string[0];
        }
        return (from piece in original.Split(',')
                let trimmed = piece.Trim()
                where !string.IsNullOrEmpty(trimmed)
                select trimmed).ToArray();
    }
}

然后:

[MyAuthorize(Order = 1, Roles = "Admin", Users="frankl")]
public class AuthorizeBaseController_Admins_frank : Controller
{
    ...    
}

不幸的是,AuthorizeAttribrute将允许您指定有效用户或有效角色 - 而不是两者。以下是MVC 3源代码的相关代码。

protected virtual bool AuthorizeCore(HttpContextBase httpContext) {
    if (httpContext == null) {
        throw new ArgumentNullException("httpContext");
    }

    IPrincipal user = httpContext.User;
    if (!user.Identity.IsAuthenticated) {
        return false;
    }

    if (_usersSplit.Length > 0 && !_usersSplit.Contains(user.Identity.Name, StringComparer.OrdinalIgnoreCase)) {
        return false;
    }

    if (_rolesSplit.Length > 0 && !_rolesSplit.Any(user.IsInRole)) {
        return false;
    }

    return true;
}

您需要将'frankl'设为管理员,或创建自定义授权attribrute
