使用 CookieContainer 的 WCF Web 服务客户端

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，并且如果我没有记错的话，我需要使用 CookieContainer 来做到这一点。

我使用项目的“添加服务引用”菜单创建了服务引用，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如下示例：

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。顺便说一句，我正在起诉 Visual Studio 2010 Beta。

先感谢您！

这是结果 ServiceReference（自动创建）：

Answer 1

当您只需在绑定上启用 cookie 时，为什么要恢复到旧技术呢？

http://megakemp.wordpress.com/2009/02/06/managing -shared-cookies-in-wcf/

Answer 2

引：
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 cookie 唯一标识该 XML Web 服务客户端的会话。为了让 XML Web 服务维护客户端的会话状态，客户端必须存储 cookie。

上面的答案只有一篇非常有用的文章的链接，但没有其他详细信息
链接唯一的答案在 StackOverflow 上不是首选，因此这里是该文章的摘要，

这里是文章中的sinnept

在 WCF 世界中，情况有些不同。 WCF 是一种与传输无关的技术，不允许 cookie 的概念直接反映在高级 API 中，因为它特定于 HTTP 协议。这实际上是在没有任何 CookieContainer 属性来设置和检索的 Web 服务客户端对象中进行的。

这是 WCF 的解决方案（这也适用于我）

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 创建的此服务引用独立于实际的通信媒介，这意味着这些服务可以使用 Web 服务、远程处理或 MSMQ 来使用。而且远程处理和MSMQ 没有Cookie 的概念。

最好使用 WSDL.exe 创建 Web 服务引用并将生成的类添加到您的项目中。我也做了同样的事情。
