api - How to C# Core OAuth without external login panel -


i'm making api exact online website form. visitor fill in information , after visitor sends it. need send exact online account client. before need accesstoken. problem don't want give user login page exact gives me. i'm searching days find way skip login or enter login information backend (there 1 login, , login client).

now authorization thing new me. far know can call authorization settings startup this:

httpcontext.authentication.getauthenticateinfoasync("exactonline");

but loginscreen don't want. thing exact telling me do:

create app registration supports automated connection wizard (your provisioning process).

is there way send them login information , visitor doesn't see loginpage.

in startup.cs

var s = new oauthoptions{ authenticationscheme = "exactonline", clientid = "clientid", clientsecret = "clientsecret", callbackpath = new pathstring("/callback"), automaticauthenticate = true, automaticchallenge = true, authorizationendpoint = new uri(string.format("{0}/api/oauth2/auth", "https://start.exactonline.nl")).tostring(), tokenendpoint = new uri(string.format("{0}/api/oauth2/token", "https://start.exactonline.nl")).tostring(), //scope = { "identity", "roles" }, events = new oauthevents {     oncreatingticket = context =>     {         context.identity.addclaim(new claim("urn:token:exactonline", context.accesstoken));         return task.fromresult(true);     } } };  app.useoauthauthentication(s);

first had code, gives me null exception when put identity in claimprincipal, because claimsprincipal null , don't know why.

httpcontext.authentication.authenticateasync("exactonline");  var identity = new claimsidentity("exactonline",claimsidentity.defaultnameclaimtype, claimsidentity.defaultroleclaimtype); identity.label = "authentication"; identity.addclaim(new claim(claimtypes.name, "username?")); identity.addclaim(new claim(claimtypes.nameidentifier, "password?"));  claimsprincipal.addidentity(identity);  var test = httpcontext.authentication.signinasync("exactonline", claimsprincipal, new authenticationproperties() { ispersistent = false }));

after tried following code, didn't work. code continue, test variable filled message: name 'innerexceptioncount' not exist in current context.

var identity = new claimsidentity("exactonline", claimsidentity.defaultnameclaimtype, claimsidentity.defaultroleclaimtype); identity.label = "authentication"; identity.addclaim(new claim("username", "username")); identity.addclaim(new claim("password", "password")); claimsprincipal claimsprincipal = new claimsprincipal(identity);  var test = httpcontext.authentication.signinasync("exactonline", claimsprincipal, new authenticationproperties() { ispersistent = false });

someone know how solve problem?

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
