如何在 c# 中的 HttpClient 中使用凭据? [英] How to use credentials in HttpClient in c#?

问题描述

我在使用 HttpClient 类访问 Delicious API 时遇到了一些问题.我有以下代码:

I am facing some problems when using the HttpClient class to access to a Delicious API. I have the following code:

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);
}

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).

When running the code above I am getting the following: Response status code does not indicate success: 401 (Unauthorized).

那么，我怎样才能得到这份工作呢?可能吗?

So, how could I get this work? Is it possible?

推荐答案

我自己也遇到了完全相同的问题.HttpClient 似乎只是忽略了 HttpClientHandler 中设置的凭据.

I had the exact same problem myself. It seems the HttpClient just disregards the credentials set in the HttpClientHandler.

然而，以下应该有效:

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);
}

不需要处理程序.
