在App.config中设置WCF ClientCredentials

Question

是否可以在App.config中为WCF设置clientcredentials？

我想避免这样做:

Using svc As New MyServiceClient
  svc.ClientCredentials.UserName.UserName = "login"
  svc.ClientCredentials.UserName.Password = "pw"

  ...
End Using

而是登录名和密码应该是配置的一部分.

扩展Ladislav Mrnka的答案,您可能会发现此实现很有用:

public class UserNameClientCredentials : ClientCredentialsElement
{
    private ConfigurationPropertyCollection properties;

    public override Type BehaviorType
    {
        get { return typeof (ClientCredentials); }
    }

    /// <summary>
    /// Username (required)
    /// </summary>
    public string UserName
    {
        get { return (string) base["userName"]; }
        set { base["userName"] = value; }
    }

    /// <summary>
    /// Password (optional)
    /// </summary>
    public string Password
    {
        get { return (string) base["password"]; }
        set { base["password"] = value; }
    }

    protected override ConfigurationPropertyCollection Properties
    {
        get
        {
            if (properties == null)
            {
                ConfigurationPropertyCollection baseProps = base.Properties;
                baseProps.Add(new ConfigurationProperty(
                                  "userName",
                                  typeof (String),
                                  null,
                                  null,
                                  new StringValidator(1),
                                  ConfigurationPropertyOptions.IsRequired));
                baseProps.Add(new ConfigurationProperty(
                                  "password",
                                  typeof (String),
                                  ""));
                properties = baseProps;
            }
            return properties;
        }
    }

    protected override object CreateBehavior()
    {
        var creds = (ClientCredentials) base.CreateBehavior();
        creds.UserName.UserName = UserName;
        if (Password != null) creds.UserName.Password = Password;
        ApplyConfiguration(creds);
        return creds;
    }
}

之后,您需要使用类似的方式注册此自定义实现

<system.serviceModel>
  <extensions>
    <behaviorExtensions>
      <add name="UserNameClientCredentials" type="MyNamespace.UserNameClientCredentials, MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
    </behaviorExtensions>
  </extensions>
...

Answer 2

这就是我为了让新的auth工作所做的

进一步扩展Mormegil的答案,这是如何使用customBehavior实现.

public class UserNameClientCredentialsElement : ClientCredentialsElement
{ // class renamed only to follow the configuration pattern
   ... // using Mormegil's implementation
}

之后你需要:

1. 注册behaviorExtension.
2. 使用config扩展定义新的behaviorConfig.(这是一个棘手的部分,如何做到这一点的报道很少.)
3. 将配置应用于端点.

使用类似的东西:

<system.serviceModel>
  <client><!--(3)-->
    <endpoint ...YourEndpointConfig... behaviorConfiguration="UserNamePasswordBehavior" />
  </client>
  <behaviors><!--(2)-->
    <endpointBehaviors>
      <behavior name="UserNamePasswordBehavior">
        <userNameClientCredentials userName="skroob" password="12345" />
        <!--Visual Studio will give you warning squiggly on <userNameClientCredentials>
            saying that "The element 'behavior' has invalid child element" 
            but will work at runtime.-->
      </behavior>
    </endpointBehaviors>
  </behaviors>
  <extensions><!--(1)-->
    <behaviorExtensions>
      <add name="userNameClientCredentials" type="MyNamespace.UserNameClientCredentialsElement, MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
    </behaviorExtensions>
  </extensions>
  ...
</system.serviceModel>

Answer 3

据我所知,由于它会创建安全漏洞,因此无法使用serviceModel配置部分.但您可以为这些值创建常规appSettings并在代码中使用它们:

svc.ClientCredentials.UserName.UserName = ConfigurationManager.AppSettings("...")

我会建议不要使用这种方法,除非你加密配置文件.

Answer 4

您可以尝试继承ClientCredentialsElement（处理默认配置部分）并添加对 UserName 和 Password 的支持。比您可以在配置文件中将此元素注册为行为扩展并使用它代替常见的配置部分。
