How to Get/Set Cookies in Windows.Web.Http API

Question

I have used the Windows.Web.Http API in my app to implemenet a website Login function.

The current situation is that I want to sign in a website and the website has a special parameter in the login post data which can be found in the login page. I found I have to save the cookie when I do the previous request. If not, it will make another random token.
I have checked those class: HttpRequestMessage, HttpResponseMessage, HttpClient, but I find nothing about the Cookies.
At last I find a class called HttpBaseProtocolFilter and it has a member called CookieManager. But I don't know what to do with it.

So I hope the answers can contain some general codes for how to get/set cookies in Windows.Web.Http API correctly.

Hello,

Welcome to our Microsoft Q&A platform!

To add or delete an HttpCookie or view the cookies associated with an app, we can refer to the HttpCookieManager.
For how to using it, you can refer the following code:

//To get/set cookies  
using (var protocolFilter = new HttpBaseProtocolFilter())  
            {  
                //get CookieManager instance  
                var cookieManager = protocolFilter.CookieManager;  
                //get cookies  
                var cookies = cookieManager.GetCookies(uri);  
                foreach (var cookie in cookies)  
                {  
                    Debug.Write(cookie.Value);  
                }  
                //you can also SetCookie  
                //cookieManager.SetCookie(MyCookie);  
            }  
  
  

Meanwhile, you can also define the cookie usage behavior that is used in the CookieUsageBehavior property.

                var protocolFilter = new HttpBaseProtocolFilter()  
                //Do not handle cookies automatically. you can set it as your requirements.  
                protocolFilter.CookieUsageBehavior = HttpCookieUsageBehavior.NoCookies;  
                // Create a HttpClient  
                var httpClient = new HttpClient(protocolFilter);  

 

Thanks.
