如何在 WPF 应用程序中的 SOAP 客户端的新请求中设置"Set-Cookie"标头响应"Cookie"标头

Question

我正在将我的 WPF 应用程序与 2 个 WCF 应用程序集成（一个是"身份验证应用程序"，另一个是需要身份验证的"真实"应用程序）。"身份验证应用程序"返回 3 个Set-Cookie标头，我需要将它们添加到"真实"应用程序的请求标头中。但是我不确定如何获得这些标头（仅获得结果）：

AuthenticationApplicationService.SoapClient authenticationSoapClient = new AuthenticationApplicationService.SoapClient("AuthenticationApplicationServiceSoap");
bool loggedInSuccess = await authenticationSoapClient.PerformLoginAsync();
// how do I get the cookie headers from this call and set them on the next?
RealService.SoapClient realSoapClient = new RealService.SoapClient("RealServiceSoap");
realSoapClient.PostAsync("hello");

对 PerformLoginAsync 的第一次调用返回 true 或 false 表示已成功登录，并且标头提示Set-Cookie 。如何获取这些标头并在下一个请求PostAsync时设置Cookie标头？

如果还有其他问题，请告诉我！

你应该使用 OperationContext，它具有可以发送 cookie 的属性。要启用 cookie ，您应该在绑定配置中将 allowcookie 属性设置为 true。

 <bindings>
  <basicHttpBinding>
    <binding name="AuthSoap" allowCookies="true" />
  </basicHttpBinding>
</bindings>
<client>
  <endpoint address="http://localhost:63599/Auth" binding="basicHttpBinding"
    bindingConfiguration="AuthSoap" contract="Auth.AuthSoap" name="AuthSoap" />
</client>

然后，您可以按如下方式调用登录方法。

 Auth.AuthSoapClient authSoapClient = new Auth.AuthSoapClient();
        using (new OperationContextScope(authSoapClient.InnerChannel))
        {
// please put the call of method in OperationContextScope
            authSoapClient.Login("admin", "admin");
          // the following code get the set-cookie header passed by server
            HttpResponseMessageProperty response = (HttpResponseMessageProperty)
            OperationContext.Current.IncomingMessageProperties[
                HttpResponseMessageProperty.Name];
            string header  = response.Headers["Set-Cookie"];
          // then you could save it some place  
        }

获取 cookie 后，每次调用方法时都应将其设置在标头中。

 Auth.AuthSoapClient authSoapClient = new Auth.AuthSoapClient();
        using (new OperationContextScope(authSoapClient.InnerChannel))
        {
             //below code sends the cookie back to server
            HttpRequestMessageProperty request = new HttpRequestMessageProperty();
            request.Headers["Cookie"] =  please get the cookie you stored when you   successfully logged in               
 OperationContext.Current.OutgoingMessageProperties[
                HttpRequestMessageProperty.Name] = request;
// please put the call of method in OperationContextScope
            string msg = authSoapClient.GetMsg();
        }

如果您觉得每次成功登录后发送cookie很麻烦。您可以考虑使用 MessageInspector，请参阅链接的最后一段代码https://megakemp.com/2009/02/06/managing-shared-cookies-in-wcf/
