将WCF服务转换为控制台应用程序

Question

I have a WCF service. Now I would like to convert it to console application. Basically, it is a simple service. It only does 2 jobs depending on client request by PowerShell request.

Invoke-WebRequest "http://localhost:10000/backup/DoBackup?id=BackupClient1"

or

Invoke-WebRequest "http://localhost:10000/backup/DoBackup?id=BackupClient2"

My service listens on request for this 2 requests.

I have this WCF code:

    myService service = new myService(_settings);
    backupServiceHost = new WebServiceHost(service, _backupAddress);
    WebHttpBinding binding = new WebHttpBinding();
    string address = "";
    ServiceEndpoint endpoint = backupServiceHost .AddServiceEndpoint(typeof(ISnapshotServiceContract), binding, address);
    backupServiceHost .Open();

I can't use WebServiceHost and WebHttpBinding in my console app. What is the best replacement for this? I'm thinking to use simple HttpClient . But I'm not sure is it a correct selection?

Answer 1

why don't use command line parameters and avoid WebServiceHost altogether? You can then just compare your args[] from Main function (see eg https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/main-and-command-args/ ) to determine if it is BackupClient1 command or BackupClient2 command.

If you want to take this concept further you can extract functionality of BackupClient1 command and BackupClient2 command into separate library and have frontends (WCF and command line) using same backend.

If you really need WCF service (as stated by comments below) please refer to this MSDN article ; you will have to provide your configuration and figure out how to indicate that you wish to end the process in nice way but it should boil down to something like this:

String baseAddress = "http://localhost:10000/backup";
BasicHttpBinding binding = new BasicHttpBinding();

using (ServiceHost host = new ServiceHost(typeof(myService)))
{
    host.AddServiceEndpoint(typeof(IMyService), binding, baseAddress);
    host.Open();

    while(true) {
         // Figure out how to exit this loop - e.g. listen to some command from service
    }
}
