示例
下面的示例将请求发送到 URL,并显示在响应中返回的 cookie。The following example sends a request to a URL and displays the cookies returned in the response.
#using <System.dll>
using namespace System;
using namespace System::Net;
// This example is run at the command line.
// Specify one argument: the name of the host to
// send the request to.
// If the request is sucessful, the example displays the contents of the cookies
// returned by the host.
int main()
{
array<String^>^args = Environment::GetCommandLineArgs();
if ( args == nullptr || args->Length != 2 )
{
Console::WriteLine( "Specify the URL to receive the request." );
Environment::Exit( 1 );
}
HttpWebRequest^ request = dynamic_cast<HttpWebRequest^>(WebRequest::Create( args[ 1 ] ));
request->CookieContainer = gcnew CookieContainer;
HttpWebResponse^ response = dynamic_cast<HttpWebResponse^>(request->GetResponse());
response->Cookies = request->CookieContainer->GetCookies( request->RequestUri );
// Print the properties of each cookie.
System::Collections::IEnumerator^ myEnum = response->Cookies->GetEnumerator();
while ( myEnum->MoveNext() )
{
Cookie^ cook = safe_cast<Cookie^>(myEnum->Current);
Console::WriteLine( "Cookie:" );
Console::WriteLine( "{0} = {1}", cook->Name, cook->Value );
Console::WriteLine( "Domain: {0}", cook->Domain );
Console::WriteLine( "Path: {0}", cook->Path );
Console::WriteLine( "Port: {0}", cook->Port );
Console::WriteLine( "Secure: {0}", cook->Secure );
Console::WriteLine( "When issued: {0}", cook->TimeStamp );
Console::WriteLine( "Expires: {0} (expired? {1})", cook->Expires, cook->Expired );
Console::WriteLine( "Don't save: {0}", cook->Discard );
Console::WriteLine( "Comment: {0}", cook->Comment );
Console::WriteLine( "Uri for comments: {0}", cook->CommentUri );
Console::WriteLine( "Version: RFC {0}", cook->Version == 1 ? (String^)"2109" : "2965" );
// Show the string representation of the cookie.
Console::WriteLine( "String: {0}", cook );
}
}
// Output from this example will be vary depending on the host name specified,
// but will be similar to the following.
/*

注解
Cookies属性提供 CookieCollection 类的实例,该实例保存与此响应关联的 cookie。The Cookies property provides an instance of the CookieCollection class that holds the cookies associated with this response.
如果关联的的 CookieContainer 属性 HttpWebRequest 为 null ,则 Cookies 属性也将为 null 。If the CookieContainer property of the associated HttpWebRequest is null, the Cookies property will also be null. 但服务器发送的任何 cookie 信息都将出现在 Headers 属性中。Any cookie information sent by the server will be available in the Headers property, however.
