的Windows Phone 8基本身份验证 [英] Windows Phone 8 Basic Authentication
问题描述
我主持使用用户名和密码基本认证头一个Windows网页API。
I have hosted a Windows Web API using a basic authentication header with username and password.
我试图创建一个登录表单，需要一个用户名和密码，并发送回一个令牌。
所以我有以下code。
I'm trying to create a login form that takes a username and password and sends back a token. so i have the following code.
我使用的是归因方法
public class BasicAuthenticationAttribute : System.Web.Http.Filters.ActionFilterAttribute
{
private IPromiseRepository promiseRepository;
public BasicAuthenticationAttribute()
{
this.promiseRepository = new EFPromiseRepository(new PropellorContext());
//repository = promiseRepository;
}
public BasicAuthenticationAttribute(IPromiseRepository promiseRepository, INewsFeedRepository newsfeedRepository)
{
this.promiseRepository = promiseRepository;
}
public override void OnActionExecuting(System.Web.Http.Controllers.HttpActionContext actionContext)
{
if (actionContext.Request.Headers.Authorization == null)
{
actionContext.Response = new System.Net.Http.HttpResponseMessage(System.Net.HttpStatusCode.Unauthorized);
}
else
{
string authToken = actionContext.Request.Headers.Authorization.Parameter;
string decodedToken = authToken;
// Encoding.UTF8.GetString(Convert.FromBase64String(authToken));
string username = decodedToken.Substring(0, decodedToken.IndexOf(":"));
string password = decodedToken.Substring(decodedToken.IndexOf("^")+1);
string APIToken = decodedToken.Substring(decodedToken.IndexOf("="));
APIToken = APIToken.Replace("=", string.Empty);
password = password.Replace("=", string.Empty);
if (!string.IsNullOrEmpty(APIToken))
{
password = password.Replace(APIToken, string.Empty);
}
if (username != null && password != null)
{
try
{
var user = promiseRepository.GetUserByName(username);
var salt = user.PasswordSalt;
System.Security.Cryptography.SHA512Managed HashTool = new System.Security.Cryptography.SHA512Managed();
Byte[] PasswordAsByte = System.Text.Encoding.UTF8.GetBytes(string.Concat(password, salt));
Byte[] EncryptedBytes = HashTool.ComputeHash(PasswordAsByte);
HashTool.Clear();
var hashedpass = Convert.ToBase64String(EncryptedBytes);
if (hashedpass == user.Password)
{
if (string.IsNullOrEmpty(user.APIToken))
{
String guid = System.Guid.NewGuid().ToString();
user.APIToken = guid;
promiseRepository.UpdateUser(user);
promiseRepository.Save();
}
if (user != null)
{
user = promiseRepository.GetUserByUserID(user.UserID);
HttpContext.Current.User = new GenericPrincipal(new ApiIdentity(user), new string[] { });
base.OnActionExecuting(actionContext);
}
}
if (APIToken != null)
{
if (user.APIToken == APIToken)
{
var userbytoken = promiseRepository.GetUserByAPIToken(APIToken);
HttpContext.Current.User = new GenericPrincipal(new ApiIdentity(userbytoken), new string[] { });
base.OnActionExecuting(actionContext);
}
}
}
catch (Exception)
{
{
actionContext.Response = new System.Net.Http.HttpResponseMessage(System.Net.HttpStatusCode.Unauthorized);
base.OnActionExecuting(actionContext);
}
throw;
}
}
}
}
}
这可与小提琴手时正确的凭据传递
This works with Fiddler when the correct credentials are passed
我试图产生我的Windows Phone应用程序相同的验证。
I'm attempting to produce the same authentication in my windows phone application.
将用户名和密码，进入基本身份验证HTTP标头。
Passes a username and password into the basic authentication http header.
不过我不知道如何做到这一点的大量diggging在exmaples的互联网很多的之后Windows Phone 7和一定的方法不存在了。
However I'm not sure how to do this after a large amount of diggging on the internet alot of the exmaples are windows phone 7 and certain methods don't exist anymore.
这是code I的到了。
This is the code i have arrived at.
private void Login1_Click(object sender, RoutedEventArgs e)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost:5650/api/start");
NetworkCredential credentials = new NetworkCredential(userName.Text + ":^",password.Text + "=");
request.Credentials = credentials;
request.BeginGetResponse(new AsyncCallback(GetSomeResponse), request);
希望有人能指点我到正确的方向。
它应该是原理简单:(
Hopefully someone can guide me into the right direction. it should be simple in principle :(
推荐答案
下面是一个使用样本的HttpClient：
Here is a sample using HttpClient:
public static async Task<String> Login(string username, string password)
{
HttpClient Client = new HttpClient();
Client.DefaultRequestHeaders.Add("Authorization", "Basic " + Convert.ToBase64String(StringToAscii(string.Format("{0}:{1}", username, password))));
var response = await Client.GetAsync(new Uri(new Uri("http://yourdomain.com"), "/login"));
var status= await response.Content.ReadAsAsync<String>();
return status;
}
当然，你可以在互联网上找到的ToBase64String功能。这里最棘手的部分是Authorization头。
And of course you can find the ToBase64String function on the internet. The tricky part here is the Authorization header.
