我制作了自己的 HttpModule，名为“JsonLogger”，用于记录 json 请求和响应。

对于日志记录，我需要一个连接字符串。

为了找到连接字符串，我在 web.config 中添加了一个，然后通过代码获取它。

网络配置

<connectionStrings>
   <add name="WebShopConfiguration" connectionString="myConString"/>
</connectionStrings>

<system.web>
   <httpModules>
     <add name="JsonLogger" type="ServiceModel.Logging.JsonLogger, ServiceModel"/>
    </httpModules>
</system.web>

<system.webServer>
   <modules>
      <add name="JsonLogger" type="ServiceModel.Logging.JsonLogger, ServiceModel"/>
   </modules>
</system.webServer>

Http模块

ConnectionString = System.Configuration.ConfigurationManager.
            ConnectionStrings["WebShopConfiguration"].ConnectionString;

一切正常，但 imo 这并不干净（未来的开发人员不会知道为什么我的 web.config 中有那个连接字符串）。

我想填写我在 web.config 中添加 httpmodule 的连接字符串。我试过了，但这不起作用（就像我已经想的那样）：

网络配置

<add name="JsonLogger" type="ServiceModel.Logging.JsonLogger, ServiceModel" ConnectionString="myConString"/>

HttpModule 中的属性

[ConfigurationProperty("ConnectionString", DefaultValue = "", IsRequired = true, IsKey = false)]
public string ConnectionString { get; set; }

经过一番研究，我仍然没有找到一种方法来做到这一点。任何人都知道我想要实现的目标是否可行？

非常感谢，凯尔

I made it work.

In my web.config I added a configSection with the type LoggingConfiguration. In the global.asax init() I get my configuration and create a new JsonLogger instance with the correct parameters.

web.config

<configSections>    
    <section name="LoggingConfiguration" type="WebServices.Services.Configurations.LoggingConfiguration"/>
</configSections>

<LoggingConfiguration
connectionString="myConString">
</LoggingConfiguration>

LoggingConfiguration.cs

public sealed class LoggingConfiguration : ConfigurationSection
{
    private const string ConnectionStringKey = "connectionString";

    [ConfigurationProperty(ConnectionStringKey, IsRequired = true)]
    public string ConnectionString
    {
        get { return (string) base[ConnectionStringKey]; }
        set { base[ConnectionStringKey] = value; }
    }        
}

Global.asax.cs

public override void Init()
{
    base.Init();
    var loggingConfiguration = ConfigurationManager.GetSection("LoggingConfiguration") as LoggingConfiguration;
    if (loggingConfiguration != null)
    {               
        new JsonLogger(loggingConfiguration.ConnectionString).Init(this); 
    }
}

This way I could remove following code in my web.config:

<connectionStrings>
   <add name="WebShopConfiguration" connectionString="myConString"/>
</connectionStrings>

<system.web>
   <httpModules>
     <add name="JsonLogger" type="ServiceModel.Logging.JsonLogger, ServiceModel"/>
    </httpModules>
</system.web>

<system.webServer>
   <modules>
      <add name="JsonLogger" type="ServiceModel.Logging.JsonLogger, ServiceModel"/>
   </modules>
</system.webServer>
