Response status code does not indicate success: 401 (Unauthorized).

在使用ASP.NET5调用IBM Bluemix上的REST API服务时出现此异常；

Response status code does not indicate success: 401 (Unauthorized).

at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult()at dotnethelloworld.Controllers.ValuesController.<Get>d__1.MoveNext()

MSDN中关于NetworkCredential 类的使用示例：

NetworkCredential myCred = new NetworkCredential(SecurelyStoredUserName,SecurelyStoredPassword,SecurelyStoredDomain);CredentialCache myCache = new CredentialCache();myCache.Add(new Uri("www.contoso.com"), "Basic", myCred);
myCache.Add(new Uri("app.contoso.com"), "Basic", myCred);WebRequest wr = WebRequest.Create("www.contoso.com");
wr.Credentials = myCache;

只是它是用的WebRequest，而我是用的HttpClient，却不生效，没有找到具体原因；但可以通过另一种方法来解决用户验证的问题。

解决方法：

设置httpClient.DefaultRequestHeaders.Authorization 属性，代码如下：

System.Net.Http.HttpClient httpClient = new System.Net.Http.HttpClient();
//将服务凭证转换为Base64编码格式
byte[] auth = Encoding.UTF8.GetBytes("用户名:密码");
String auth64 = Convert.ToBase64String(auth);
//创建并指定服务凭证，认证方案为Basic
httpClient.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", auth64);retString = await httpClient.GetStringAsync(uri);
