【中文标题】如何在 WPF 应用程序中 SOAP 客户端的“Set-Cookie”标头响应的新请求中设置“Cookie”标头

【英文标题】：How do I set "Cookie" header in a new request from "Set-Cookie" header response for a SOAP client in a WPF application

【问题描述】：

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。但我不确定如何获取我能得到的那些标题（只有结果）：

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 的第一次调用返回真或假以成功登录，并且标头包括Set-Cookie。如何获取这些标头并将下一个请求中的 Cookie 标头设置为 PostAsync？

如果还有其他问题，请告诉我！

【参考方案1】：

您应该使用 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>

那么就可以如下调用登录方法了。

 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  
        

获得cookie后，每次调用方法时都应在标头中设置它。

 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();
        

如果登录成功后每次都发送cookie很麻烦，可以考虑使用MessageInspector，参考链接最后一段代码 https://megakemp.com/2009/02/06/managing-shared-cookies-in-wcf/
