一个简单的例子，控制层：
.controller('publishController',['$scope','publishService', function($scope,publishService){publishService.getData().then(function(answer){$scope.data = answer.data;console.info(answer);},function(error){$scope.error = error;});}])

　　服务层：

app.service('publishService',['$http','$q',function($http,$q){
return {getData:function(){var deferred = $q.defer();var promise = $http.post(url);promise.then(// 通讯成功的处理function(answer){//在这里可以对返回的数据集做一定的处理,再交由controller进行处理answer.status = true;deferred.resolve(answer);},// 通讯失败的处理function(error){// 可以先对失败的数据集做处理，再交由controller进行处理error.status = false;deferred.reject(error);});//返回promise对象，交由controller继续处理成功、失败的业务回调return deferred.promise;}
}
}]);

　　app：

var app = angular.module("myApp", ['ngAnimate','ngRoute']);
