I am trying to call SignIn in angular.
Login(reqobj: { RedirectUrl: string; }) {
var Url = this.GeturlFromServerName(this.baseUrl) + "Account/SignIn";this.baseUrl+reqobj.RedirectUrl;
return this.http.get(Url, {
headers: {
'Content-Type': 'application/json;charset=UTF-8',
'Accept': 'application/json; charset=utf-8',
"Access-Control-Allow-Origin": "*"
} })
}
Controller
[EnableCors("CorsPolicy")]
[AllowAnonymous]
[HttpGet, Route("SignIn")]
public async Task SignIn(string redirectUri)
{
if (!HttpContext.User.Identity.IsAuthenticated)
{
try
{
await HttpContext.ChallengeAsync(OpenIdConnectDefaults.AuthenticationScheme, new AuthenticationProperties() { RedirectUri = redirectUri });
}
catch (Exception e)
{
_loggWriter.LogError("Login Exception :", e);
}
}
}
Startup.cs

{
options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;

})
.AddCookie()

{
o.ClientId = clientId;
o.ResponseType = "id_token";
o.GetClaimsFromUserInfoEndpoint = true;
o.MetadataAddress = metadataAddress;
o.SignedOutRedirectUri = PostLogoutRedirectUri;
o.Events = new OpenIdConnectEvents
{
OnRemoteFailure = OnAuthenticationFailed
};

services.AddAuthorization();

return Task.FromResult(0);
