如何在asp.net的web.config位置路径中添加和删除授权用户

本文关键字：添加 路径 删除 用户 授权 位置 config asp net web | 更新日期: 2023-09-27 18:28:40

我正在尝试以编程方式从web.config中添加和删除授权用户。我正在使用Windows身份验证。

这是我在web.config 上看到的

  <location path="Admin">
    <system.web>
      <authorization>
        <allow users="domain'user1, domain'user2"/>
        <deny users="*"/>
      </authorization>
    </system.web>
  </location>

现在，在代码中，我有以下代码。

protected void UpdateUsers()
{
    System.Configuration.Configuration config = (Configuration)WebConfigurationManager.OpenWebConfiguration("~");
    ConfigurationLocationCollection section = config.Locations;
    foreach (ConfigurationLocation location in section)
    {
        if(location.Path == "Admin")
        {
            AuthorizationSection admin_section = (AuthorizationSection)config.GetSection("system.web/authorization");
            AuthorizationRule thisAuth = new AuthorizationRule(AuthorizationRuleAction.Allow) ;
                thisAuth.Users.Add("domain''username");
             admin_section.Rules.Add(thisAuth);
             admin_section.CurrentConfiguration.Save();
        }
    }
}

上面的代码是在system.web上添加部分，而不是在管理位置。

我找到了答案。这是更新后的代码。

protected void UpdateUsers()
{
    Configuration config = (Configuration)WebConfigurationManager.OpenWebConfiguration("~");
    AuthorizationSection root_section = (AuthorizationSection)config.GetSection("system.web/authorization");
    //Remove all Current Users to root location.
    root_section.Rules.Clear();
    //Add New Users to root location.
    AuthorizationRule rootAuth = new AuthorizationRule(AuthorizationRuleAction.Allow);
    rootAuth.Users.Add("domain''rootusername1");
    rootAuth.Users.Add("domain''rootusername2");
    rootAuth.Users.Add("domain''rootusername3"); 
    root_section.Rules.Add(rootAuth);
    ////Add Deny All Users to root location.
    AuthorizationRule rootDeny = new AuthorizationRule(AuthorizationRuleAction.Deny);
    rootDeny.Users.Add("*");
    root_section.Rules.Add(rootDeny);
    root_section.CurrentConfiguration.Save();
    //Other Locations  
    ConfigurationLocationCollection section = config.Locations;
    foreach (ConfigurationLocation location in section)
    {
        if (location.Path == "admin") //This is case Sensitive
        {
            Configuration adminConfig = (Configuration)location.OpenConfiguration();
            AuthorizationSection admin_section = (AuthorizationSection)adminConfig.GetSection("system.web/authorization");
            //Remove all Current Users to admin location.
            admin_section.Rules.Clear();
            ////Add New Users to admin location.
            AuthorizationRule adminAuth = new AuthorizationRule(AuthorizationRuleAction.Allow);
            adminAuth.Users.Add("domain''adminusername1");
            adminAuth.Users.Add("domain''adminusername2");
            adminAuth.Users.Add("domain''adminusername3");
            adminAuth.Users.Add("domain''adminusername4");
            admin_section.Rules.Add(adminAuth);
            adminAuth = null;
            ////Add Deny All Users to root location.
            AuthorizationRule adminDeny = new AuthorizationRule(AuthorizationRuleAction.Deny);
            adminDeny.Users.Add("?"); // For some reason if I remove this line it says "Object reference not set to an instance of an object"
            adminDeny.Users.Add("*");
            admin_section.Rules.Add(adminDeny);
            admin_section.CurrentConfiguration.Save();
        }
    }
}

希望这对某人有帮助。
