IWebProxy.IsBypassed(Uri) Método

Definição

Namespace:

System.Net

Assembly:

System.Net.Primitives.dll

Indica que o proxy não deve ser usado para o host especificado.

public:
 bool IsBypassed(Uri ^ host);

public bool IsBypassed (Uri host);

abstract member IsBypassed : Uri -> bool

Public Function IsBypassed (host As Uri) As Boolean

Parâmetros

host

Uri

O Uri do host a ser verificado quanto ao uso do proxy.

Retornos

Boolean

true caso o servidor proxy não deva ser usado para host; caso contrário, false.

Exemplos

O exemplo a seguir usa a IsBypassed propriedade para determinar se o servidor proxy deve ser usado para o host especificado.

WebProxy_Interface^ webProxy_Interface = gcnew WebProxy_Interface( gcnew Uri( "http://proxy.example.com" ) );

webProxy_Interface->Credentials = gcnew NetworkCredential( "myusername", "mypassword" );

Console::WriteLine( "The web proxy is : {0}", webProxy_Interface->GetProxy( gcnew Uri( "http://www.contoso.com" ) ) );

// Check if the webproxy can ne bypassed for the site "http://www.contoso.com".
if ( webProxy_Interface->IsBypassed( gcnew Uri( "http://www.contoso.com" ) ) )
{
   Console::WriteLine( "Web Proxy is by passed" );
}
else
{
   Console::WriteLine( "Web Proxy is not by passed" );
}

WebProxy_Interface webProxy_Interface = new WebProxy_Interface(new Uri("http://proxy.example.com"));

webProxy_Interface.Credentials = new NetworkCredential("myusername", "mypassword");

Uri testUri = new Uri("http://www.contoso.com");

// Determine whether the Web proxy can be bypassed for the site "http://www.contoso.com".
if(webProxy_Interface.IsBypassed(testUri))
{
    Console.WriteLine("Web Proxy is by passed");
}
else
{
    Uri? webProxyServer = webProxy_Interface.GetProxy(testUri);
    // In general, we wouldn't expect the condition (`webProxyServer! == testUri`) true here, if  IsBypassed returns `false`.
    // However, technically our interface can allow that.
    if (webProxyServer is null || webProxyServer! == testUri)
    {
        Console.WriteLine("Web proxy is bypassed");
    }
    else
    {
        Console.WriteLine("Web proxy is not bypassed");
        Console.WriteLine($"The web proxy is: {webProxyServer!}");
    }
}

 Public Shared Sub Main()
     Dim webProxy_Interface As New WebProxy_Interface(New Uri("http://proxy.example.com"))
     
     webProxy_Interface.Credentials = New NetworkCredential("myusername", "mypassword")
     
     Console.WriteLine("The web proxy is : {0}", webProxy_Interface.GetProxy(New Uri("http://www.contoso.com")))
     
     'Determine whether the Web proxy can be bypassed for the site "http://www.contoso.com".
 console.writeline("For the Uri http://www.contoso.com , the ")
     If webProxy_Interface.IsBypassed(New Uri("http://www.contoso.com")) Then
         Console.WriteLine("webproxy is by passed")
     Else
         Console.WriteLine("webproxy is not bypassed")
     End If 
 End Sub

Comentários

O IsBypassed método indica se o servidor proxy deve ser usado para acessar o host especificado no host parâmetro . Se IsBypassed retornar true, o proxy não será usado para entrar em contato com o host e a solicitação será passada diretamente para o servidor. A obtenção false de IsBypassed não garante que o URI seja proxie; você ainda precisa chamar o GetProxy método para determinar isso.
