How to use credentials in HttpClient in c#?
提问by MikePR
I am facing some problems when using the HttpClient class to access to a Delicious API. I have the following code:
在使用 HttpClient 类访问 Delicious API 时，我遇到了一些问题。我有以下代码：
try
{
const string uriSources = "https://api.del.icio.us/v1/tags/bundles/all?private={myKey}";
using (var handler = new HttpClientHandler { Credentials = new
NetworkCredential("MyUSER", "MyPASS") })
{
using (var client = new HttpClient(handler))
{
var result = await client.GetStringAsync(uriSources);
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "ERROR...", MessageBoxButton.OK);
}
When running the code above I am getting the following: Response status code does not indicate success: 401 (Unauthorized).
运行上面的代码时，我得到以下信息：响应状态代码不表示成功：401（未经授权）。
So, how could I get this work? Is it possible?
那么，我怎样才能得到这份工作呢？是否可以？
Thanks in advance
提前致谢

The code you are showing works for me against an authenticated resource. I suspect Delicious is doing something weird.
您显示的代码适用于经过身份验证的资源。我怀疑 Delicious 正在做一些奇怪的事情。
Considering you are on Windows Phone, it is a pain to debug with Fiddler, so what I suggest is getting a Runscopeaccount. Install this message handlerwhich will redirect your request via the RunScope debugger. Once you do this, I suggest you look at the www-authenticate header and examine what that is returning.
考虑到您使用的是 Windows Phone，使用 Fiddler 进行调试很痛苦，因此我建议您获取一个Runscope帐户。安装此消息处理程序，它将通过 RunScope 调试器重定向您的请求。完成此操作后，我建议您查看 www-authenticate 标头并检查返回的内容。
If all else fails you can always set the Authentication header directly with basic auth credentials. You don't need to use the Credentials class.
如果所有其他方法都失败了，您始终可以使用基本身份验证凭据直接设置身份验证标头。您不需要使用 Credentials 类。

I had the exact same problem myself. It seems the HttpClientjust disregards the credentials set in the HttpClientHandler.
我自己也遇到了完全相同的问题。似乎HttpClient只是无视在HttpClientHandler.
The following shall work however:
但是，以下内容将起作用：
using System.Net.Http.Headers; // For AuthenticationHeaderValue
const string uri = "https://example.com/path?params=1";
using (var client = new HttpClient()) {
var byteArray = Encoding.ASCII.GetBytes("MyUSER:MyPASS");
var header = new AuthenticationHeaderValue(
"Basic", Convert.ToBase64String(byteArray));
client.DefaultRequestHeaders.Authorization = header;
var result = await client.GetStringAsync(uri);
}
No need for the handler.
不需要处理程序。

I faced similar issue. In my case, setting Domain property for NetworkCredentials worked. You can try setting Domain.
我遇到了类似的问题。就我而言，为 NetworkCredentials 设置域属性有效。您可以尝试设置域。
