示例

下面的代码示例演示如何捕获自定义证书策略的证书策略异常。 它假定已定义证书策略对象，Web 资源的统一资源标识符 (URI) 包含在变量 myUri中，并且有一个名为 ProcessResponse 的方法执行应用程序的工作。

ServicePointManager::CertificatePolicy = gcnew MyCertificatePolicy;

// Create the request and receive the response
try
{
   WebRequest^ myRequest = WebRequest::Create( myUri );
   WebResponse^ myResponse = myRequest->GetResponse();
   ProcessResponse( myResponse );
   myResponse->Close();
}
// Catch any exceptions
catch ( WebException^ e ) 
{
   if ( e->Status == WebExceptionStatus::TrustFailure )
   {
      // Code for handling security certificate problems goes here.
   }
   // Other exception handling goes here
}

ServicePointManager.CertificatePolicy = new MyCertificatePolicy();

// Create the request and receive the response
try
{
    WebRequest myRequest = WebRequest.Create(myUri);
    WebResponse myResponse = myRequest.GetResponse();
    ProcessResponse(myResponse);
    myResponse.Close();
}
// Catch any exceptions
catch (WebException e)
{
    if (e.Status == WebExceptionStatus.TrustFailure)
    {
        // Code for handling security certificate problems goes here.
    }
    // Other exception handling goes here
}

ServicePointManager.CertificatePolicy = New MyCertificatePolicy()
       
' Create the request and receive the response
Try
    Dim myRequest As WebRequest = WebRequest.Create(myUri)
    Dim myResponse As WebResponse = myRequest.GetResponse()
    
    ProcessResponse(myResponse)

    myResponse.Close()
    
' Catch any exceptions
Catch e As WebException
    If e.Status = WebExceptionStatus.TrustFailure Then
        ' Code for handling security certificate problems goes here.
    End If
    ' Other exception handling goes here
 End Try

注解

当 属性 CertificatePolicy 设置为接口对象时 ICertificatePolicy ，对象 ServicePointManager 将使用在该实例中定义的证书策略，而不是默认证书策略。

默认证书策略允许有效的证书和已过期的有效证书。
