我使用以下基本身份驗證方法並輸出以下錯誤 - 「$ id」:「1」,「消息」:「授權已被拒絕此請求」,當我打電話時 - api /值授權401錯誤
[Authorize]
public IEnumerable<string> Get()
{
return new string[] { "value1", "value2" };
}
BasicAuthMessageHandler類:
public class BasicAuthMessageHandler : DelegatingHandler
{
private const string BasicAuthResponseHeader = "WWW-Authenticate";
private const string BasicAuthResponseHeaderValue = "Basic";
[Inject]
public iUser Repository { get; set; }
protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
AuthenticationHeaderValue authValue = request.Headers.Authorization;
if (authValue != null && !String.IsNullOrWhiteSpace(authValue.Parameter))
{
api_login parsedCredentials = ParseAuthorizationHeader(authValue.Parameter);
if (parsedCredentials != null)
{
IPrincipal principal;
if (TryGetPrincipal(parsedCredentials.username, parsedCredentials.password, out principal))
{
Thread.CurrentPrincipal = principal;
}
}
}
return base.SendAsync(request, cancellationToken).ContinueWith(task =>
{
var response = task.Result;
if (response.StatusCode == HttpStatusCode.Unauthorized && !response.Headers.Contains(BasicAuthResponseHeader))
{
response.Headers.Add(BasicAuthResponseHeader, BasicAuthResponseHeaderValue);
}
return response;
});
}
private api_login ParseAuthorizationHeader(string authHeader)
{
string[] credentials = Encoding.ASCII.GetString(Convert.FromBase64String(authHeader)).Split(new[] { ':' });
if (credentials.Length != 2 || string.IsNullOrEmpty(credentials[0]) || string.IsNullOrEmpty(credentials[1])) return null;
return new api_login()
{
username = credentials[0],
password = credentials[1],
};
}
private bool TryGetPrincipal(string userName, string password, out IPrincipal principal)
{
// this is the method that authenticates against my repository (in this case, hard coded)
// you can replace this with whatever logic you'd use, but proper separation would put the
// data access in a repository or separate layer/library.
api_login user = Repository.Validate2(userName, password);
if (user != null)
{
// once the user is verified, assign it to an IPrincipal with the identity name and applicable roles
//principal = new GenericPrincipal(new GenericIdentity(user.username));
principal = new GenericPrincipal(new GenericIdentity(user.username), System.Web.Security.Roles.GetRolesForUser(user.role));
return true;
}
principal = null;
return false;
}
}
用戶等級:
public api_login Validate2(string userName, string Password)
{
// Find a user that matches that username and password (this will only validate if both match)
return db.api_login.FirstOrDefault(u => u.username == userName && u.password == Password);
}
上午我米西在代碼中的東西,這是正確的方法來驗證Web API? 謝謝
謝謝你的迴應。我設法解決問題,每當我嘗試登錄時,我得到以下錯誤 - 對象引用未設置爲對象的實例。在以下代碼行--- api_login user = Repository.Validate2(userName,password);感謝您的幫助。 – user3070072
這意味着您的Repository尚未注入。確保在訪問屬性之前設置了該值 –
嗨,感謝您的幫助。我正在寫求助,上面怎麼能調試basicAUthHandler類。我遵循你的答案,但是當我調試代碼時,它無法在代碼中發現錯誤。我正在使用依賴注入器(Ninject),這是否可能導致錯誤。感謝您的幫助和時間。 – user3070072
