Angular JS不是函数错误

Question

我是Angular的新手，我不能让这个工厂工作，我只是在另一个visual studio实例中使用Web服务。 这是代码：

主要工厂：

nngmodule.factory('generaldataFactory', ['$http', function ($http, $httpProvider) {
var dataFactory = {};

dataFactory.getMethodWebService = function (pMethod, pUrl, pCache, pTimeout, pParams, pFunctionSuccess, pFunctionError) {
    $http({
        method: pMethod, url: pUrl, cache: pCache, timeout: pTimeout, params: pParams
    }).then(pFunctionSuccess, pFunctionError);
};

return dataFactory;

}]）;

个人工厂（使用一个以上）

  ngmodule.factory('miFactory', ['$http', function (generaldataFactory) {

var miFact = {};

miFact.GetNoticiasList = function (functionSuccess, functionError) {
    return generaldataFactory.getMethodWebService("GET", 'http://localhost:40900/Noticias/GetNoticiasList', false, 25000, {}, functionSuccess, functionError);
};
miFact.FiltrarNoticias = function (id, functionSuccess, functionError) {
    return generaldataFactory.getMethodWebService("GET", 'http://localhost:40900/Noticias/GetNoticiaById/', false, 25000, { 'id': id }, functionSuccess, functionError);
};

return miFact;

}]）;

控制器：

ngmodule.controller（'miController'，function（miFactory）{var scope = this;

var registerSuccess = function (response) {

}
var registerError = function (response) {  

}

scope.noticiasList = {}
scope.noticiasList =    miFactory.GetNoticiasList(registerSuccess,registerError);

}）;

---

错误：

TypeError: generaldataFactory.getMethodWebService is not a function at Object.miFact.GetNoticiasList (MiFactory.js:6) at new <anonymous> (controllers.js:13) at Object.invoke (angular.js:4478) at extend.instance (angular.js:9136) at nodeLinkFn (angular.js:8248) at compositeLinkFn (angular.js:7680) at compositeLinkFn (angular.js:7684) at publicLinkFn (angular.js:7555) at angular.js:1662 at Scope.$eval (angular.js:15989)

Answer 1

您没有注入必要的依赖项（这发生在多个文件中）。 数组中的参数需要与工厂函数中的参数匹配。

ngmodule.factory('miFactory', ['$http', function (generaldataFactory) {

如果你想使用generaldataFactory，你需要注入它：

ngmodule.factory('miFactory', ['generaldataFactory', function (generaldataFactory) {

一些更正

通用数据工厂

//Notice that in the factory, the providers don't are availables. 
//Don't inject Providers in the factories/services
//Don't set callback for manage the responses of $http in the factory, instead
//return the result of the $http method

nngmodule.factory('generaldataFactory', ['$http', function ($http) {
    var dataFactory = {};

    dataFactory.getMethodWebService = function (pMethod, pUrl, pCache, pTimeout, pParams) {
        return $http({
                method: pMethod, 
                url: pUrl, 
                cache: pCache, 
                timeout: pTimeout, 
                params: pParams
              });
    };

return dataFactory;
}]);

个人工厂

//Inject generaldataFactory instead $http.
//The better approach in this case it's use the $q service for resolve/reject the http responses 
ngmodule.factory('miFactory', ['generaldataFactory','$q', function (generaldataFactory,$q) {

var miFact = {};

miFact.GetNoticiasList = function (functionSuccess, functionError) {
    var d = $q.deferred();

    return generaldataFactory
           .getMethodWebService("GET",'http://localhost:40900/Noticias/GetNoticiasList', false, 25000, {})
           .then(function(response){
              d.resolve(response);
              return d.promise;
            }, function(err){
              d.reject(err);
              return d.promise;
           });


};

调节器

//Inject your factory and resolve the responses
ngmodule.controller('miController',['miFactory', function(miFactory) { 
    var scope = this;

    var registerSuccess = function (response) {
       scope.noticiasList = response;
    }
    var registerError = function (response) {  
       alert("Error!");
    }

    scope.noticiasList = {}
    miFactory.GetNoticiasList.then(registerSuccess,registerError);
});
