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?

当前回答
使用System.Net.Http程序集的AuthenticationHeaderValue类
public AuthenticationHeaderValue(
string scheme,
string parameter
)
我们可以像这样设置或更新httpclient现有的授权头:
httpclient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", TokenResponse.AccessToken);
其他回答
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);
我是这样做的:
using (HttpClient httpClient = new HttpClient())
{
Dictionary<string, string> tokenDetails = null;
var messageDetails = new Message { Id = 4, Message1 = des };
HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost:3774/");
var login = new Dictionary<string, string>
{
{"grant_type", "password"},
{"username", "sa@role.com"},
{"password", "lopzwsx@23"},
};
var response = client.PostAsync("Token", new FormUrlEncodedContent(login)).Result;
if (response.IsSuccessStatusCode)
{
tokenDetails = JsonConvert.DeserializeObject<Dictionary<string, string>>(response.Content.ReadAsStringAsync().Result);
if (tokenDetails != null && tokenDetails.Any())
{
var tokenNo = tokenDetails.FirstOrDefault().Value;
client.DefaultRequestHeaders.Add("Authorization", "Bearer " + tokenNo);
client.PostAsJsonAsync("api/menu", messageDetails)
.ContinueWith((postTask) => postTask.Result.EnsureSuccessStatusCode());
}
}
}

我在寻找一个好的方法来处理这个问题,我也在考虑同样的问题。希望这个答案能帮助到每个和我一样有同样问题的人。
using (var client = new HttpClient())
{
var url = "https://www.theidentityhub.com/{tenant}/api/identity/v1";
client.DefaultRequestHeaders.Add("Authorization", "Bearer " + accessToken);
var response = await client.GetStringAsync(url);
// Parse JSON response.
....
}
参考来自https://www.theidentityhub.com/hub/Documentation/CallTheIdentityHubApi
使用基本授权和Json参数。
using (HttpClient client = new HttpClient())
{
var request_json = "your json string";
var content = new StringContent(request_json, Encoding.UTF8, "application/json");
var authenticationBytes = Encoding.ASCII.GetBytes("YourUsername:YourPassword");
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
Convert.ToBase64String(authenticationBytes));
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var result = await client.PostAsync("YourURL", content);
var result_string = await result.Content.ReadAsStringAsync();
}
方法是这样的,
httpClient.DefaultRequestHeaders.Authorization =
new AuthenticationHeaderValue("Bearer", "Your Oauth token");
