Angularjs difference between Services,Factories & Providers

Services

Syntax: module.service( 'serviceName', function ); 
Result: When declaring serviceName as an injectable argument you will be provided with an instance of the function. In other words new FunctionYouPassedToService().

Factories

Syntax: module.factory( 'factoryName', function ); 
Result: When declaring factoryName as an injectable argument you will be provided with the value that is returned by invoking the function reference passed to module.factory.

Providers

Syntax: module.provider( 'providerName', function ); 
Result: When declaring providerName as an injectable argument you will be provided with ProviderFunction().$get(). The constructor function is instantiated before the $get method is called - ProviderFunction is the function reference passed to module.provider.

Providers have the advantage that they can be configured during the module configuration phase.

AngularJS Http Interceptor Example

- under the routing configuration

$httpProvider.interceptors
    .push(['$q', '$injector', function ($q, $injector) {
        return function (promise) {
            return promise.then(function (response) {
                return response;
            }, function (response) {
                if (response.status === 401) {
                    $injector.get('$state').go('login');
                } else if (response.status === 403) {
                    $injector.get('$state').go('resources');
                } else if (response.status === 404) {
                    $injector.get('$state').go('login');
                }
                return $q.reject(response);
            });
        };
    }]);

AngularJs Embaded CSS to Html Tag by ng-style

<a ng-style="{ 'background-color' : color, 'background' : color}">
</a>


here color is $scope / $rootScope variable

Difference between $http, $resource & Restangular

$http - $http is built into Angular, so there’s no need for the extra overhead of loading in an external dependency. $http is good for quick retrieval of server-side data that doesn't really need any specific structure or complex behaviours. It’s probably best injected directly into your controllers for simplicity’s sake.

$resource - $resouce is good for situations that are slightly more complex than $http. It’s good when you have pretty structured data, but you plan to do most of your crunching, relationships, and other operations on the server side before delivering the API response. $resource doesn't let you do much once you get the data into your JavaScript app, so you should deliver it to the app in its final state and make more REST calls when you need to manipulate or look at it from a different angle. Any custom behaviour on the client side will need a lot of boilerplate.

Restangular - Restangular is a perfect option for complex operations on the client side. It lets you easily attach custom behaviours and interact with your data in much the same way as other model paradigms you've used in the past. It’s promise-based, clean, and feature-rich. However, it might be overkill if your needs are basic, and it carries along with it any extra implications that come with bringing in additional third-party dependencies.

Date Calculation : Java to get date before or after some days from today

Calendar cNow = Calendar.getInstance();

Date dNow = cNow.getTime();          

cNow.add(Calendar.DATE, Day);           

Date beforeDate = cNow.getTime();           

SimpleDateFormat format = 

         new SimpleDateFormat("MMM dd, yyyy hh:mm:ss a");

           

String dateNow = format.format(dNow);          

String dayBefore = format.format(beforeDate);          

System.out.println(dateNow);         

System.out.println(dayBefore);

________________________________________________

Day is a integer value either in + or - base on requirement

- Day will give you past date

+ Day will give you future date   

Call Rest service from JAVA Core, Post method

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.net.MalformedURLException;

import org.apache.http.HttpResponse;

import org.apache.http.client.methods.HttpPost;

import org.apache.http.entity.StringEntity;

import org.apache.http.impl.client.DefaultHttpClient;

public class SubscriberService {

       public void sendPost() throws Exception {

              try {

                      DefaultHttpClient httpClient = new DefaultHttpClient();

                      HttpPost postRequest = new HttpPost("api url");

                      StringEntity input = new StringEntity(

                                    "{"

                                    + "\"object\":\"value\""

                                    + "}");

                      input.setContentType("application/json");

                      postRequest.setEntity(input);

                      HttpResponse response = httpClient.execute(postRequest);

                      BufferedReader br = new BufferedReader(new InputStreamReader(

                                    (response.getEntity().getContent())));

                      String output;

                      System.out.println("Output from Server .... \n");

                      while ((output = br.readLine()) != null) {

                             System.out.println(output);

                      }

                      httpClient.getConnectionManager().shutdown();

              } catch (MalformedURLException e) {

                      e.printStackTrace();

              } catch (IOException e) {

                      e.printStackTrace();

              }

       }

}

Could not load file or assembly or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

I was able to fix this error by 

1. finding the assembly DLL in Windows Explorer, 
2. right clicking,
3. choosing Properties
4. pressing the "unblock" button. 

Now Try To Publish it will work

Asp.net HttpClient POST Method call API

string response = null;

            using (var client = new HttpClient())

            {

                client.BaseAddress = new Uri(BASE_URL);

                var content = new FormUrlEncodedContent(new[]

                    {

                        new KeyValuePair<string, string>("param1", value1),

                        new KeyValuePair<string, string>("param2", value2),

                    });

                var result = client.PostAsync(API_URL, content).Result;

                response = result.Content.ReadAsStringAsync().Result;

              

            }

here BASE_URL is some thing like www.mastermoin.com

and API_URL is looking like /api/helloservice
