Angular ngresource 更新方法不是函数

Angular ngresource update method not a function

我正在使用 MEAN Stack。我正在尝试将 PUT 请求添加到我的 $ngResource 中,但出现错误:

TypeError: conService.update is not a function

at m.$scope.joinCon (http://localhost:3000/javascripts/chirpApp-ngresource.js:217:14)

我的代码

//My factory
app.factory('conService', function ($resource) {return $resource('/api/cons', {'update': { method: 'PUT' }});});

//My update
conService.update({conName:$scope.cons.conName},$scope.cons);};

//My api to get all conventions
.get(function (req, res) {Con.find(function (err, cons) {if (err) { return res.send(500, err); }return res.send(cons);});})

任何人都可以帮我弄清楚我在更新中遗漏了什么吗?谢谢

由于它是一个工厂,因此您应该在控制器代码中实例化,然后再通过以下方式使用它:

var cs = new conService();
cs.update(/*params here*/);
