如何將參數傳遞給AngularJS工廠？

Question

我有一個封裝了websocket連接的AngularJS工廠。我想有一些這些在我的每個連接到不同的終端控制器使用（由下面personId指定）

angular.module('personService', ['ngResource']). 
    factory('Person', function($resource) { 
     var service = {}; 

     if (service.ws) { return; } 

     var personId = ??? // This will be different for each person. 
     var ws = new WebSocket("ws://127.0.0.1:5000/" + personId + "/"); 

     ws.onopen = function() { 
      console.log("WebSocket opened"); 
     }; 

     ws.onerror = function(err) { 
      console.log("WebSocket error " + err); 
     } 

     ws.onmessage = function(message) { 
      service.callback(message.data); 
     }; 

     service.ws = ws; 

     service.send = function(message) { 
      service.ws.send(message); 
     } 

     service.subscribe = function(callback) { 
      service.callback = callback; 
     } 

     return service; 
     }); 

function Ctrl($scope, $timeout, Person) { 

    $scope.p1 = Person("personId1"); // ?? 
    $scope.p2 = Person("personId1"); // ?? 
}

更新對不起，我其實誤解了你一點。 定義您的人構造爲正常，即

function Person(id) { 
    var ws = new Websocket('some url ' + id); 
} 

然後注射到工廠

app.factory('PersonFactory', function() { return Person; }); 

然後在控制器

app.controller('MyCtrl', function ($scope, PersonFactory) { 
    $scope.person1 = new PersonFactory(1); 
    $scope.person2 = new PersonFactory(2); 
} 

等瞧」。
