Question

我已经构建了一个提出多个请求的简单服务。该服务有两种方法。我无法在服务中调用另一个方法。

app.factory('Report', ['$http', function($http){
var Authors = {

    reports : [],
    requests :[{'url':'data/data.cfm','response':'first'},
               {'url':'data.json','response':'second'},
               {'url':'data.json','response':'third'},
               {'url':'data.json','response':'forth'}],


getReport : function(target, source, response, callback) {
    return $http({  url:source, 
                    method:"POST", 
                    params:{url : target}
                }).success(function(result) {
                    $scope.progress = response;
                    angular.extend($scope.user, result)
                    console.log($scope.user)
      }
      ).error(function(error){
                    $scope.progress = response
                })
},

    startQueue : function (target) {
        var promises = [];
        this.requests.forEach(function (obj, i) {
            console.log(obj.url)
            promises.push(getReport(target, obj.url, obj.response, function(value){
                reports.push(value);
                console.log(value)
            }));
        });
        $q.all(promises).then(function () {
            console.log("Finito");
        },function(error){
            console.log("errori")
        });
    }

};

return Authors;
}])

当我尝试从startQueue内部调用getReport时，我收到错误：未定义getReport。

将您的工厂更改为：

app.factory('Report', ['$http', function($http){
    var Authors = {

        reports : [],
        requests :[{'url':'data/data.cfm','response':'first'},
                   {'url':'data.json','response':'second'},
                   {'url':'data.json','response':'third'},
                   {'url':'data.json','response':'forth'}],
    };

    Authors.getReport = function(target, source, response, callback) {

    };
    Authors.startQueue = function (target) {

    };

    return Authors;
}])

我知道这是'真的很晚'，但看起来是因为你没有注入$ q。

变化：

app.factory('Report', ['$http', function($http){

到

app.factory('Report', ['$http','$q', function($http,$q){

AngularJs从self调用内部服务函数
