asp.net - Return user roles from bearer token of Web API -

-

i developing web api 2 project. authentication using bearer token. on successful authentication api returns json object.

{"access_token":"vn2kwvz...",    "token_type":"bearer",    "expires_in":1209599,    "username":"username",    ".issued":"sat, 07 jun 2014 10:43:05 gmt",    ".expires":"sat, 21 jun 2014 10:43:05 gmt"}

now want return user roles in json object. changes need make in order user roles json response?

after searching lot found can create custom properties , can set them authentication ticket. in way can customize response can have custom values may required @ caller end.

here code send user roles along token. requirement. 1 can modify code send required data.

public override async task grantresourceownercredentials(oauthgrantresourceownercredentialscontext context)     {         using (usermanager<applicationuser> usermanager = _usermanagerfactory())         {             applicationuser user = await usermanager.findasync(context.username, context.password);              if (user == null)             {                 context.seterror("invalid_grant", "the user name or password incorrect.");                 return;             }              claimsidentity oauthidentity = await usermanager.createidentityasync(user,                 context.options.authenticationtype);              claimsidentity cookiesidentity = await usermanager.createidentityasync(user,                 cookieauthenticationdefaults.authenticationtype);             list<claim> roles = oauthidentity.claims.where(c => c.type == claimtypes.role).tolist();             authenticationproperties properties = createproperties(user.username, newtonsoft.json.jsonconvert.serializeobject(roles.select(x=>x.value)));              authenticationticket ticket = new authenticationticket(oauthidentity, properties);             context.validated(ticket);             context.request.context.authentication.signin(cookiesidentity);         }     }    public static authenticationproperties createproperties(string username, string roles)     {         idictionary<string, string> data = new dictionary<string, string>         {             { "username", username },             {"roles",roles}         };         return new authenticationproperties(data);     }

this return me out put as

`{"access_token":"vn2kwvz...",  "token_type":"bearer",  "expires_in":1209599,  "username":"username",  ".issued":"sat, 07 jun 2014 10:43:05 gmt",  ".expires":"sat, 21 jun 2014 10:43:05 gmt"  "roles"=["role1","role2"] }`

hope information helpful one. :)

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
