Windows应用商店中使用HttpClient（C＃）进行摘要式身份验证 [英] Digest authentication in Windows Store app using HttpClient (C#)

问题描述

我在这个问题上苦苦挣扎了一周。
我必须在Windows Store App中将API与摘要身份验证一起使用，但是当我使用此代码时，在以下代码行中得到System.ArgumentNullException：

I'm struggling with this problem for a week. I have to use API with Digest authentication in Windows Store App, but while I'm using this code I get System.ArgumentNullException in this line of code:

HttpHandler.Credentials = credCache;

以下是其余代码：

var credCache = new CredentialCache();
credCache.Add(new Uri("https://myserverIP/api"),"Digest",new NetworkCredential("mylogin", "mypassword") );
var HttpHandler = new HttpClientHandler();
HttpHandler.Credentials = credCache;
var httpClient = new HttpClient(HttpHandler);
var answer = await httpClient.GetAsync(new Uri("https://myserverIP/api/?function=someKindOfFunction"));
answer.EnsureSuccessStatusCode();

我在做什么错了？

推荐答案

解决此问题的快速方法是使用 credCache.GetCredentials（）而不是仅 credCache 在为HttpHandler分配值时。凭据如下：

A quick fix to your issue is to use credCache.GetCredentials() instead of just credCache when assigning a value to HttpHandler. Credentials as such:

var credCache = new CredentialCache();
credCache.Add(new Uri("https://myserverIP/api"),"Digest",new NetworkCredential("mylogin", "mypassword") );
var HttpHandler = new HttpClientHandler();
HttpHandler.Credentials = credCache.GetCredential(new Uri("https://myserverIP/api"), "Digest");

此功能无需 ArgumentNullException 。

希望这会有所帮助。
