使用CookieContainer的WCF Web服务客户端

c#wcfweb-servicescookiescookiecontainer
7

我开发了一个小型的C#表单应用程序，它调用了一个Web服务。一切都很好，但是我需要保持状态，为此我需要使用CookieContainer（如果我没有弄错的话）。

我使用项目的“添加服务引用”菜单创建了服务引用，一切都很顺利。但我不知道如何在创建的客户端上添加CookieManager。

我找到了一些示例，这些示例显示了一些样本，例如：

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。顺便说一下，我正在使用 Visual Studio 2010 Beta。
提前感谢！

为了让我创建的服务客户端具有CookieContainer属性，我不得不创建一个WebReference（.NET 2.0-查看向导表单底部的兼容性标题），但我需要使用VS2010默认方式来完成。有什么想法吗？ - Timmo

我找到了唯一的功能性解决方案，它运行得非常好。 - David
Link的简短信息（它有效）：binding.AllowCookies = true; using(var webServiceProxy = new ReportExecutionServiceSoapClient(binding, endpoint)){} - Stefan Steiger
作为警告，链接中的集中管理解决方案对Cookie采取了非常简化的视图，并且不符合任何3个不同的Cookie RFC（2109、2965、6265），因此重要的是要了解您正在连接到的服务器的要求。例如，我曾经看到一个服务器按照2109发送多个逗号分隔的Cookie，但只包括它想要更新的那些。 - Shane Courtrille

上面的回答只有一个非常有用的文章链接，但没有其他细节。
在StackOverflow上，仅链接唯一的答案并不受欢迎，因此这里是该文章的摘要

以下是文章的摘要

在WCF世界中，情况略有不同。 WCF作为一种传输无关技术，不允许直接反映cookie的概念在高级API中，因为它是特定于HTTP协议的。 实际上，这意味着Web服务客户端对象没有任何CookieContainer属性可设置和检索。

以下是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();
    }
}

这个服务引用是使用WCF创建的，而WCF独立于实际的通信媒介，这意味着这些服务可以使用WebService或Remoting或MSMQ。而Remoting和MSMQ没有Cookie的概念。

最好使用WSDL.exe创建您的Web服务引用，并将生成的类添加到您的项目中。我也是这样做的。
