Question

我开发了一个调用Web服务的小型C＃表单应用程序。一切都运行良好，但我需要保持状态，并且如果我没有弄错，我需要使用CookieContainer。

我使用项目的“添加服务参考”菜单创建了服务参考，一切运行良好。但我不知道如何在创建的客户端上添加CookieManager。

我发现一些示例显示了样本：

serviceClient.CookieContainer=new CookieContainer()

但事实并非如此。我的服务客户端没有这样的属性。我顺便提起Visual Studio 2010 Beta。

提前谢谢！

这是由此产生的ServiceReference（自动创建）：

Answer 1

为什么要恢复旧技术，只需在绑定上启用cookie？

Answer 2

引用：如果XML Web服务方法使用会话状态，则会在响应标头中将cookie传递回XML Web服务客户端，该客户端唯一标识该XML Web服务客户端的会话。为了使XML Web服务能够维护客户端的会话状态，客户端必须存储cookie。

The answer above 只有一个非常有用的文章的链接，但没有其他详细信息
链接唯一的答案不是 StackOverflow 上的首选，因此这里是该文章的摘要

这是文章中的错误

<块引用>

在 WCF 世界中，情况略有不同。 WCF 是一种与传输无关的技术，不允许将 cookie 的概念直接反映在高级 API 中，因为它特定于 HTTP 协议。这实际上转化为没有任何 CookieContainer 属性要设置和检索的 Web 服务客户端对象。

这是 WCF 的解决方案（也适用于我）

private static void Main(object[] args)
{
    string sharedCookie;

    MyWebServiceClient client = new MyWebServiceClient();

    using (new OperationContextScope(client.InnerChannel))
    {
        client.DoSomething();

        // Extract the cookie embedded in the received web service response
        // and stores it locally
        HttpResponseMessageProperty response = (HttpResponseMessageProperty)
        OperationContext.Current.IncomingMessageProperties[
            HttpResponseMessageProperty.Name];
        sharedCookie = response.Headers["Set-Cookie"];
    }

    MyOtherWebServiceClient otherClient = new MyOtherWebServiceClient();

    using (new OperationContextScope(otherClient.InnerChannel))
    {
        // Embeds the extracted cookie in the next web service request
        // Note that we manually have to create the request object since
        // since it doesn't exist yet at this stage
        HttpRequestMessageProperty request = new HttpRequestMessageProperty();
        request.Headers["Cookie"] = sharedCookie;
        OperationContext.Current.OutgoingMessageProperties[
            HttpRequestMessageProperty.Name] = request;

        otherClient.DoSomethingElse();
    }
}

Answer 4

使用WCF和WCF创建的此服务引用独立于实际的通信媒介，这意味着可以使用Web服务或远程处理或MSMQ来使用这些服务。远程处理和MSMQ没有Cookie的概念。

使用WSDL.exe更好地创建Web服务引用，并在项目中添加生成的类。我做了同样的事情。

使用CookieContainer的WCF Web服务客户端
