javascript - AngularJS: Performing $http request inside custom service and returning data -

-

i have defined custom http service in angular looks this:

angular.module('myapp')   .factory('myhttpserv', function ($http) {    var url = "http://my.ip.address/"    var http = {       async: function (webservice) {           var promise = $http.get(url + webservice, { cache: true }).then(function (response) {             return response.data;         });           return promise;        }   };   return http; });

and can access service in controller so: 

angular.module('myapp')   .controller('myctrl', function (myhttpserv) {    var webservice = 'getuser?u=3'    myhttpserv.async(webservice).then(function (data) {       console.log(data);   })  });

however need streamline process contained inside service static url , returns data. can call in controller so: 

 angular.module('myapp')   .controller('myctrl', function ($scope, myhttpserv) {        console.log(myhttpserv.var1);       console.log(myhttpserv.var2);       etc...  });

i can't seem tweak service functionality. know correct way it?

option 1 - use promise api

angular.module('myapp').factory('myhttpserv', function ($http) {   return $http.get('http://my.ip.address/getuser?u=3', { cache: true }); });

controller:

angular.module('myapp').controller('myctrl', function ($scope, myhttpserv) {      myhttpserv.then(function(response){          console.log(response.data);      });      });

option 2 - using route resolve

angular.module('myapp', ['ngroute']).config(['$routeprovider',   function($routeprovider) {     $routeprovider.       when('/myctrl', {         templateurl: 'myview.html',         controller: 'myctrl',         resolve: {         load: function (myhttpserv) {             return myhttpserv;         }       });   }]);

service:

angular.module('myapp').factory('myhttpserv', function ($http) {       var data = {};       var url = "http://my.ip.address/";       var promise = $http.get(url + 'getuser?u=3', { cache: true }).then(function (response) {                 data = response.data;             });       return data;     });

controller:

 angular.module('myapp')   .controller('myctrl', function ($scope, myhttpserv) {        console.log(myhttpserv.data.var1);       console.log(myhttpserv.data.var1);       etc...  });

option 3 - use $interval service

angular.module('myapp').factory('myhttpserv', function ($http) {   var data = {};   var url = "http://my.ip.address/";   var promise = $http.get(url + 'getuser?u=3', { cache: true }).then(function (response) {             data = response.data;         });   return data; });

controller:

angular.module('myapp').controller('myctrl', function ($scope, $interval, myhttpserv) {       $scope.intervalpromise = $interval(function(){           if (object.keys(myhttpserv.data).length!=0)           {               console.log(myhttpserv.data);               $interval.cancel($scope.intervalpromise);           }       }, 100);     });

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()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
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...
