// client.BaseAddress = new Uri(URL);
// Add an Accept header for JSON format.
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
// List data response.
HttpResponseMessage response = client.GetAsync(URL).Result; // Blocking call!
String res = response.ToString();
Console.WriteLine(res);

即使我传递了正确的凭据,我也收到未经授权的错误。有什么想法吗?
我尝试了StackOverflow上发布的几乎所有答案。
对于基本身份验证,您需要在名为"基本"的授权标头中发送凭据,并将 base64 编码的"用户名:密码"作为值。这应该可以完成工作:
var headerVal = Convert.ToBase64String(Encoding.UTF8.GetBytes("admin@client:admin"));
var header = new AuthenticationHeaderValue("Basic", headerVal);
client.DefaultRequestHeaders.Authorization = header;
