我認爲最好的方法是使用Cookies。下面是我在my project使用的解決方案:
創建一個類將數據保存在它
[DataContract]
[Serializable()]
public class AuthData {
[DataMember]
public String UserName { get; set; }
[DataMember]
public String FirstName { get; set; }
[DataMember]
public String LastName { get; set; }
[DataMember]
public String Email { get; set; }
// any other property you need to a light-store for each user
public override string ToString() {
string result = "";
try {
using (MemoryStream stream = new MemoryStream()) {
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(stream, this);
result = Convert.ToBase64String(stream.ToArray());
}
} catch (Exception ex) {
throw new HttpException(ex.Message);
}
return result;
}
static public AuthData FromString(String data) {
AuthData result = null;
try {
byte[] array = Convert.FromBase64String(data);
using (MemoryStream stream = new MemoryStream(array)) {
stream.Seek(0, 0);
BinaryFormatter formatter = new BinaryFormatter();
result = (AuthData)formatter.Deserialize(stream, null);
}
} catch (Exception ex) {
throw new HttpException(ex.Message);
}
return result;
}
}
簽到方法:
public static bool SignIn(string userName, string password, bool persistent){
if (Membership.ValidateUser(userName, password)) {
SetAuthCookie(userName, persistent);
return true;
}
return false;
}
設置AuthCookie:
public static void SetAuthCookie(string userName, bool persistent) {
AuthData data = GetAuthDataFromDB(); // implement this method to retrieve data from database as an AuthData object
var ticket = new FormsAuthenticationTicket(
1,
userName,
DateTime.Now,
DateTime.Now.Add(FormsAuthentication.Timeout),
persistent,
data.ToString(),
FormsAuthentication.FormsCookiePath
);
string hash = FormsAuthentication.Encrypt(ticket);
HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, hash);
cookie.Expires = DateTime.Now.Add(FormsAuthentication.Timeout);
cookie.HttpOnly = false;
cookie.Path = FormsAuthentication.FormsCookiePath;
HttpContext.Current.Response.Cookies.Add(cookie);
}
獲取AuthCookie:
public static AuthData GetAuthCookie() {
if (HttpContext.Current.User != null && HttpContext.Current.User.Identity.IsAuthenticated && HttpContext.Current.User.Identity is FormsIdentity) {
FormsIdentity id = (FormsIdentity)HttpContext.Current.User.Identity;
FormsAuthenticationTicket ticket = id.Ticket;
var data = AuthData.FromString(ticket.UserData);
HttpContext.Current.Items["AuthDataContext"] = data;
return data;
}
return null;
}
在ControllerBase:
private AuthData _authData;
private bool _authDataIsChecked;
public AuthData AuthData {
get {
_authData = System.Web.HttpContext.Current.Items["AuthDataContext"] as AuthData;
if (!_authDataIsChecked && _authData == null) {
SignService.GetAuthCookie();
_authData = System.Web.HttpContext.Current.Items["AuthDataContext"] as AuthData;
_authDataIsChecked = true;
}
return _authData;
}
}
非常重要的對我來說問題。 –
