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
相反,登录名和密码应该是配置的一部分。

扩展Ladislav Mrnka的回答,你可能会发现这个实现很有用:
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
的内容注册此自定义实现<system.serviceModel>
<extensions>
<behaviorExtensions>
<add name="UserNameClientCredentials" type="MyNamespace.UserNameClientCredentials, MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
</behaviorExtensions>
</extensions>
...

这就是我为使新的auth工作而做的事情
在Mormegil's answer上进一步扩展这是如何使用customBehavior实现。
public class UserNameClientCredentialsElement : ClientCredentialsElement
{ // class renamed only to follow the configuration pattern
... // using Mormegil's implementation
}
之后你需要:
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>
答案 2 :(得分:8)
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("...")
我建议不要使用这种方法,除非你加密配置文件。

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。您可以在配置文件中将此元素注册为行为扩展,并使用它而不是通用配置节。
