我有一个HttpClient,我正在使用一个REST API。但是,我在设置授权标头时遇到了麻烦。我需要将标头设置为我从执行OAuth请求中接收到的令牌。 我看到了一些。net的代码,建议如下:
httpClient.DefaultRequestHeaders.Authorization = new Credential(OAuth.token);
然而,凭据类在WinRT中不存在。有人知道如何设置授权头吗?

使用现有的库可能更容易。
例如,Identity Server 4中添加了下面的扩展方法 https://www.nuget.org/packages/IdentityModel/
public static void SetBasicAuthentication(this HttpClient client, string userName, string password);
//
// Summary:
// Sets a basic authentication header.
//
// Parameters:
// request:
// The HTTP request message.
//
// userName:
// Name of the user.
//
// password:
// The password.
public static void SetBasicAuthentication(this HttpRequestMessage request, string userName, string password);
//
// Summary:
// Sets a basic authentication header for RFC6749 client authentication.
//
// Parameters:
// client:
// The client.
//
// userName:
// Name of the user.
//
// password:
// The password.
public static void SetBasicAuthenticationOAuth(this HttpClient client, string userName, string password);
//
// Summary:
// Sets a basic authentication header for RFC6749 client authentication.
//
// Parameters:
// request:
// The HTTP request message.
//
// userName:
// Name of the user.
//
// password:
// The password.
public static void SetBasicAuthenticationOAuth(this HttpRequestMessage request, string userName, string password);
//
// Summary:
// Sets an authorization header with a bearer token.
//
// Parameters:
// client:
// The client.
//
// token:
// The token.
public static void SetBearerToken(this HttpClient client, string token);
//
// Summary:
// Sets an authorization header with a bearer token.
//
// Parameters:
// request:
// The HTTP request message.
//
// token:
// The token.
public static void SetBearerToken(this HttpRequestMessage request, string token);
//
// Summary:
// Sets an authorization header with a given scheme and value.
//
// Parameters:
// client:
// The client.
//
// scheme:
// The scheme.
//
// token:
// The token.
public static void SetToken(this HttpClient client, string scheme, string token);
//
// Summary:
// Sets an authorization header with a given scheme and value.
//
// Parameters:
// request:
// The HTTP request message.
//
// scheme:
// The scheme.
//
// token:
// The token.
public static void SetToken(this HttpRequestMessage request, string scheme, string token);

如果您正在使用Visual Studio IISExpress调试模式并连接到HTTP端口而不是HTTPS端口,您可能会发现身份验证头被删除。
切换到SLL连接,它们将再次出现。
不确定原因,可能是设置重定向HTTP流量,导致身份验证被删除。
使用c# HttpClient设置基本身份验证。下面的代码为我工作。
using (var client = new HttpClient())
{
var webUrl ="http://localhost/saleapi/api/";
var uri = "api/sales";
client.BaseAddress = new Uri(webUrl);
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.ConnectionClose = true;
//Set Basic Auth
var user = "username";
var password = "password";
var base64String =Convert.ToBase64String( Encoding.ASCII.GetBytes($"{user}:{password}"));
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",base64String);
var result = await client.PostAsJsonAsync(uri, model);
return result;
}
方法是这样的,
httpClient.DefaultRequestHeaders.Authorization =
new AuthenticationHeaderValue("Bearer", "Your Oauth token");
static async Task<AccessToken> GetToken()
{
string clientId = "XXX";
string clientSecret = "YYY";
string credentials = String.Format("{0}:{1}", clientId, clientSecret);
using (var client = new HttpClient())
{
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.UTF8.GetBytes(credentials)));
List<KeyValuePair<string, string>> requestData = new List<KeyValuePair<string, string>>();
requestData.Add(new KeyValuePair<string, string>("grant_type", "client_credentials"));
FormUrlEncodedContent requestBody = new FormUrlEncodedContent(requestData);
var request = await client.PostAsync("https://accounts.spotify.com/api/token", requestBody);
var response = await request.Content.ReadAsStringAsync();
return JsonConvert.DeserializeObject<AccessToken>(response);
}
}
request.DefaultRequestHeaders.Authorization =
new AuthenticationHeaderValue(
"Basic", Convert.ToBase64String(
System.Text.ASCIIEncoding.ASCII.GetBytes(
$"{yourusername}:{yourpwd}")));
