[英]WCF restful service injecting WebOperationContext with Autofac
[英]Injecting wcf channel with autofac
我想在WCF服務(使用Autofac.Integration.Web)中使用autofac來解決對wcf通道的依賴性。 我正在嘗試的是這樣的事情
Global.asax中
protected void Application_Start(object sender, EventArgs e)
{
var builder = new ContainerBuilder();
builder.RegisterType<CheckingService>();
builder.Register(c => new ChannelFactory<IAuthenticationService>(
new WSHttpBinding("wsHttpBinding_Common"),
new EndpointAddress(ConfigurationManager.AppSettings["AuthenticationServiceUrl"])).CreateChannel())
.SingleInstance();
AutofacHostFactory.Container = builder.Build();
}
使用通道的類:
public AuthorizationManager(IAuthenticationService authenticationServiceClient)
{
AuthenticationServiceClient = authenticationServiceClient;
}
但是我越來越
Exception Details: System.MissingMethodException: No parameterless constructor defined for this object.
當我嘗試使用WCF測試客戶端時。
但是,如果我只是在方法中新建頻道,客戶端不會抱怨:
所以我的理解是我在綁定中做錯了什么,但不確定是什么。
public AuthorizationManager()
{
AuthenticationServiceClient = new ChannelFactory<IAuthenticationService>(
new WSHttpBinding("wsHttpBinding_Common"),
new EndpointAddress(ConfigurationManager.AppSettings["AuthenticationServiceUrl"])).CreateChannel();
}
因此,如果我錯了,請糾正我,問題應該出在綁定中,但是我不知道我在做什么錯。
謝謝
更新
ResourceServiceAuthorizationManager以nuget包的形式出現
public class ResourceServiceAuthorizationManager : ServiceAuthorizationManager
{
public ResourceServiceAuthorizationManager();
public IAuthenticationService AuthenticationServiceClient { get; set; }
public Guid ResourceId { get; set; }
public override bool CheckAccess(OperationContext operationContext);
}
我不確定您是否以正確的方式使用DI來使用WCF服務,但是初始化可能是
builder.Register(c => new ChannelFactory<IAuthenticationService>(
new WSHttpBinding("wsHttpBinding_Common"),
new EndpointAddress(ConfigurationManager.AppSettings["AuthenticationServiceUrl"]))
.CreateChannel()).As<IAuthenticationService>().SingleInstance();
