我是OAuth的新用戶。有誰知道如何使用OAuth登錄，我已成功地產生通過將用戶名和密碼令牌，並在JavaScript中使用sessionStorage.setItem（「的accessToken」）來存儲令牌，使用OAuth登錄並從數據庫檢索用戶詳細信息
<script type="text/javascript">
$(document).ready(function() {
$('#btnLogin').click(function() {
$.ajax({
url: '/token',
method: 'POST',
contentType: 'application/json',
data: {
username: $('#txtEmail').val(),
password: $('#txtPassword').val(),
grant_type: 'password'
},
success: function (response) {
sessionStorage.setItem('accessToken', response.access_token);
sessionStorage.setItem('userName', response.userName);
window.location.href = "Jobs.html";
},
error: function (jqXHR) {
$('#divErrorText').text(jqXHR.responseText);
$('#divError').show('fade');
}
});
});
});
</script>
這是我的自定義OAuthAuthorizationServerProvider
public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
var userManager = context.OwinContext.GetUserManager<ApplicationUserManager>();
//find a match with the entered username and password
AppUser user = await userManager.FindAsync(context.UserName, context.Password);
if(user == null)
{
context.SetError("Access Denied, Invalid Username or Password");
return;
}
//responsible to fetch the authenticated user identity from the database and returns an object of type 「ClaimsIdentity」
ClaimsIdentity oAuthIdentity = await user.GenerateUserIdentityAsync(userManager, OAuthDefaults.AuthenticationType);
ClaimsIdentity cookieIdentity = await user.GenerateUserIdentityAsync(userManager, CookieAuthenticationDefaults.AuthenticationType);
AuthenticationProperties properties = CreateProperties(user.UserName);
AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, properties);
context.Validated(ticket);
context.Request.Context.Authentication.SignIn(cookieIdentity);
}
我怎麼能登錄的用戶，我怎麼能檢索來自數據庫的用戶名和電子郵件，而無需使用sessionStorage.getItem。我需要爲此調用另一個LogIn API嗎？ （像這樣）
public async Task<ActionResult> LogIn(LogInModel model)
{
if(!ModelState.IsValid)
{
return View();
}
userManager.FindAsync.
var user = await userManager.FindAsync(model.Email, model.Password);
// sign in the user using the cookie authentication middleware SignIn(identity)
if (user != null)
{
await SignIn(user);
return Redirect(GetRedirectUrl(model.ReturnUrl));
}
ModelState.AddModelError("", "Kas Error Message -Inavlid email or password");
return View();
}
private async Task SignIn(AppUser user)
{
var identity = await userManager.CreateIdentityAsync(
user, DefaultAuthenticationTypes.ApplicationCookie);
GetAuthenticationManager().SignIn(identity);
}
很抱歉，如果我聽起來厚:)任何幫助表示讚賞
