把所有接口都封装到service层

angular.module("MyController", [])
    .controller("IndexController", ["$scope", "githubService",                                function($scope, githubService){
        $scope.name = "dreamapple";
        $scope.show = true;
        githubService.getPullRequests().then(function(result){
            $scope.data = result;
        },function(error){
            $scope.data = "error!";
        },function(progress){
            $scope.progress = progress;
            $scope.show = false;
        });
    }]);

 angular.module("MyService", [])
    .factory('githubService', ["$q", "$http", function($q, $http){
        var getPullRequests = function(){
        var deferred = $q.defer();
        var promise = deferred.promise;
        var progress;
        $http.get("https://api.github.com/repos/angular/angular.js/pulls")
        .success(function(data){
            var result = [];
            for(var i = 0; i < data.length; i++){
                result.push(data[i].user);
                progress = (i+1)/data.length * 100;
                deferred.notify(progress);
            }
            deferred.resolve(result);
            })
        .error(function(error){
            deferred.reject(error);
        });
        return promise;
    }

    return {
        getPullRequests: getPullRequests
    };
}]);

建立service.js,放到里面，用的时候注入就可以了
