Exemplo do Sistema de Interação Remota: Hosting in Information Internet Serviços (IIS)

The seguinte exemplo Implements a Basic Web Serviço with a few complications. O BinaryFormatter é usado porque a carga é mais compacta e o sistema leva menos tempo para serializar e desserializar o fluxo. In addition, IF Information Internet Serviços (IIS) is Using Windows Integrated Authentication (also Known as NTLM autenticação), the servidor authenticates the cliente and then returns to the cliente the identidade that IIS was able to Authenticate. Finally, you can Ajuda Protect Your serviço da Web by Changing the URL in the arquivo de configuração cliente to use "https" as the esquema de protocolo and Configuring IIS to Require criptografia Secure Sockets Layer (SSL) for that diretório virtual (the exemplo not demonstrar this processo).

Para compilar e executar esse exemplo

1. Salvar todas as Arquivos em um nomeado Diretório RemoteIIS.

2. Compile the entire exemplo by Digitação the seguinte Commands at the prompt de comando:

   [Visual Basic]

   vbc /t:library ServiceClass.vb
   vbc /r:System.Runtime.Remoting.dll /r:ServiceClass.dll Client.vb
   

   [C#]

   csc /t:library ServiceClass.cs
   csc /r:System.Runtime.Remoting.dll /r:ServiceClass.dll Client.cs
   

3. Criar a \Bin subdiretório and copiar ServiceClass.dll into that Diretório.

4. Criar um aplicativo no IIS. Verifique o alias do Aplicativo "HttpBinary" e defina a pasta de origem para o diretório "RemoteIIS".

5. Defina o método de autenticação para esse diretório virtual para autenticação integrada do Windows (anteriormente conhecida como autenticação NTLM). If acessar Anonymous is Selecionado, HttpContext.Current.User.Identity.Name will be null and GetServerString will Return "***unavailable***" for the usuário alias. To evitar this from occuring, anular seleção Anonymous Acessar.

6. Certifique-se de que o IIS é iniciado; At the prompt de comando in the Diretório "RemoteIIS", tipo cliente.

This aplicativo Runs on a single computador OR Na Horizontal a rede. Se você deseja executar este aplicativo através de uma rede, você deve substituir "localhost" na configuração do cliente com o nome do computador remoto.
