在中等信任环境中从Web.config读取system.net/mailSettings/smtp [英] Reading system.net/mailSettings/smtp from Web.config in Medium trust environment

问题描述

我有一些继承的代码，它们在Web.config的system.net/mailSettings/smtp部分中存储SMTP服务器，用户名和密码.

I have some inherited code which stores SMTP server, username, password in the system.net/mailSettings/smtp section of the Web.config.

它曾经这样读取它们:

Configuration c = WebConfigurationManager.OpenWebConfiguration(HttpContext.Current.Request.ApplicationPath);
MailSettingsSectionGroup settings = (MailSettingsSectionGroup)c.GetSectionGroup("system.net/mailSettings");
return settings.Smtp.Network.Host;

但是当我不得不部署到中等信任环境时，这失败了.

But this was failing when I had to deploy to a medium trust environment.

因此，按照此问题的回答 ，我将其重写为像这样使用GetSection():

SmtpSection settings = (SmtpSection)ConfigurationManager.GetSection("system.net/mailSettings/smtp");
return settings.Network.Host;

但是在中等信任的情况下，它仍然给我一个SecurityException，并显示以下消息:

But it's still giving me a SecurityException on Medium trust, with the following message:

请求ConfigurationPermission 尝试访问时失败 配置部分 'system.net/mailSettings/smtp'.到 允许所有呼叫者访问数据 对于此部分，请设置部分 属性'requirePermission'等于 配置文件中的"false" 声明此部分的地方.

Request for ConfigurationPermission failed while attempting to access configuration section 'system.net/mailSettings/smtp'. To allow all callers to access the data for this section, set section attribute 'requirePermission' equal 'false' in the configuration file where this section is declared.

因此，我尝试了此requirePermission属性，但无法弄清楚将其放置在何处.

So I tried this requirePermission attribute, but can't figure out where to put it.

如果我将其应用于< smtp>节点，我收到一个ConfigurationError:无法识别的属性'requirePermission'.请注意，属性名称区分大小写."

If I apply it to the <smtp> node, I get a ConfigurationError: "Unrecognized attribute 'requirePermission'. Note that attribute names are case-sensitive."

如果我将其应用于< mailSettings>节点，我仍然收到SecurityException.

If I apply it to the <mailSettings> node, I still get the SecurityException.

在中等信任度下，有什么方法可以通过编程方式到达此配置节吗?还是我应该放弃它，然后将设置移至< appSettings>?

Is there any way to get at this config section programatically under medium trust? Or should I just give up on it and move the setting into <appSettings>?

推荐答案

requirePemission属性出现在<configSections>分组中，该分组与您遇到安全问题的web.config部分匹配.

The requirePemission attribute goes on the <configSections> grouping that matches the part fo the web.config you are having the security issue with.

此外，您不必使用代码来实际阅读设置即可发送邮件-您只需使用空白的SmtpClient:

additionally, you don't have to actually read the settings using code to send mail - you can simply use a blank SmtpClient:

 new SmtpClient.Send(MyMailMessage);

默认情况下，它将使用config部分中的设置进行发送.

it will send using the settings from the config sections by default.
