asp.net core - AuthenticationHandler ending request prematurely -

-



i'm trying make .net core authenticationhandler custom logic. whenever make request page in auth handler runs fine returns 200 without executing code end controller. i've distilled down simplified version.

startup.cs:

public void configureservices(iservicecollection services) {     services.addauthentication("dummy")         .addscheme<authenticationschemeoptions, dummyauthhandler>("dummy", null);     ...

my handler:

public class dummyauthhandler : authenticationhandler<authenticationschemeoptions> {     public dummyauthhandler(ioptionsmonitor<authenticationschemeoptions> options,          iloggerfactory logger, urlencoder encoder, isystemclock clock) :              base(options, logger, encoder, clock)     {     }      protected override task<authenticateresult> handleauthenticateasync()         => task.fromresult(authenticateresult.success(                new authenticationticket(new claimsprincipal(), "dummy")));      protected override task handlechallengeasync(authenticationproperties properties)           => task.completedtask; }

i'm thinking i'm missing 1 of methods needed tell framework continue processing request, , not think authentication handler wants page redirected. maybe need add call next() somewhere?

cracked this , this... claimsidentity returning isauthenticated = false, why thought needed handlechallengeasync in first place. here's fixed handler looks like:

public class dummyauthhandler : authenticationhandler<authenticationschemeoptions> {     public dummyauthhandler(ioptionsmonitor<authenticationschemeoptions> options,          iloggerfactory logger, urlencoder encoder, isystemclock clock) :              base(options, logger, encoder, clock)     {     }      protected override task<authenticateresult> handleauthenticateasync()         => task.fromresult(authenticateresult.success(                new authenticationticket(new claimsprincipal(                    new claimsidentity("abc")), "dummy"))); }

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
