我正在实现WcfClientFactory
public class WcfClientFactory : IDisposable
{
internal const string WildcardConfigurationName = "*";
//We track all channels created by this instance so they can be destroyed
private readonly List<WeakReference<IDisposable>> _disposableItems = new List<WeakReference<IDisposable>>();
public T CreateClient<T>(string configurationName = WildcardConfigurationName, string address=null)
{
var factory = new ChannelFactory<T>(configurationName);
if (!string.IsNullOrWhiteSpace(address))
{
factory.Endpoint.Address = new EndpointAddress(address);
}
var channel = factory.CreateChannel();
var clientChannel = (IClientChannel)channel;
clientChannel.Open();
_disposableItems.Add(new WeakReference<IDisposable>(clientChannel,false));
return channel;
}
void IDisposable.Dispose()
{
//No finalizer is implemented as there are no directly held scarce resources.
//Presumably the finalizers of items in disposableItems will handle their own teardown
//if it comes down to it.
foreach (var reference in _disposableItems)
{
IDisposable disposable;
if (reference.TryGetTarget(out disposable))
{
disposable.Dispose();
}
}
}
}
所以我可以创建WCF clientChannel
var client = _wcfClientFactory.CreateClient<ICrmService>(address);
如果WCF没有任何身份验证,它将很好地工作。现在,我们想向该工厂添加身份验证。我该怎么做?我尝试了下面的代码
public T CreateClientWithBasicAuthentication<T>(string address)
{
WSHttpBinding myBinding = new WSHttpBinding();
myBinding.Security.Mode = SecurityMode.Transport;
myBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
var factory = new ChannelFactory<T>(myBinding, new EndpointAddress(address));
var channel = factory.CreateChannel();
var clientChannel = (IClientChannel)channel;
////CrmServiceClient csc = (CrmServiceClient)channel;
////csc.ClientCredentials.UserName.UserName = _UserName;
////csc.ClientCredentials.UserName.Password = _Password;
clientChannel.Open();
_disposableItems.Add(new WeakReference<IDisposable>(clientChannel, false));
return channel;
}
但是它会产生异常,并要求提供用户名和密码。如何设置密码和用户名?
变量工厂具有Credential的成员,但只能获取。这就是为什么我认为这必须是一种在调用CreateChannel
之前设置凭据的方法谢谢
这里的描述可能有问题,您的想法是正确的,在这里我们可以设置客户端身份验证凭据。
var factory = new ChannelFactory<T>(myBinding, new EndpointAddress(address));
//for HttpClientCredentialType.Basic
factory.Credentials.UserName.UserName = "administrator";
factory.Credentials.UserName.Password = "abcd1234!";
//for window credentials
//factory.Credentials.Windows.ClientCredential.UserName = "adminsitrator";
//factory.Credentials.Windows.ClientCredential.Password = "abcd1234!";
var channel = factory.CreateChannel();
此外,请注意通道工厂使用的绑定类型应与服务器端的绑定类型一致。请随时让我知道问题是否仍然存在。
