Microservice
Microservice is a collection of freely deployable services. It is an approach to building application software as a collection of independently deployable, compact, modular services. Herein, each service executes a different operation and interacts with one another via a simple, well-defined interface API.
Why do we need Microservice ?
The 3 prime reasons that modern enterprises need microservice architecture are:
● To defend against a failure of traffic or performance surge.
● To scale graciously
● To reduce the number of individuals engaging in each codebase.
How Can Setup Microservices ?
First project
Step-1 Install Project
Step-2 Go to In project
Step-3 composer require laravel/passport
—— composer require laravel/passport=~7.5.0 (For Laravel version 5.8)
Step-4
config/app.php in providers
Laravel\Passport\PassportServiceProvider::class,
Step-5
Set database from .env file
php artisan migrate
composer require lcobucci/jwt=3.3.3
==============================================
Step-6
First open “App\User”
replace from User extents –
in top – use Laravel\Passport\HasApiTokens;
use Illuminate\Notifications\Notifiable;
class User extends Authenticatable
{
use HasApiTokens, Notifiable;
}
Step-8
app/providers/AuthServiceProvider.php
In top – use Laravel\Passport\Passport;
in function boot()- Passport::routes();
Step-9
config/auth.php of api’drivers (Token will be replace)
‘driver’ => ‘passport’,
Step-10
Route/api.php
Route::get(‘/file_name’, ‘FileController@index’);
If Require then———————
install guzzle pakages-
composer require guzzlehttp/guzzle~6.5.0 If Require then————
app/Http/Kernel.php
‘client_credentials’ => \Laravel\Passport\Http\Middleware\CheckClientCredentials::class,
====================================================================================================================================
Second Project=====
Step-1 Install Project
Step-2 Go to In project
Step-3 composer require laravel/passport
—— composer require laravel/passport=~7.5.0 (For Laravel version 5.8)
Step-4
config/app.php in providers
Laravel\Passport\PassportServiceProvider::class,
Step-5
set database from .env file
php artisan migrate
composer require lcobucci/jwt=3.3.3
Step-6
php artisan passport:install
and set client_credentials in first project
--------------------------------------------==============================================
Step-7
First open “App\User”
replace from User extents –
in top – use Laravel\Passport\HasApiTokens;
use Illuminate\Notifications\Notifiable;
class User extends Authenticatable
{
use HasApiTokens, Notifiable;
}
Step-8
app/providers/AuthServiceProvider.php
In top – use Laravel\Passport\Passport;
in function boot()- Passport::routes();
Step-9
config/auth.php of api’drivers (Token will be replace)
‘driver’ => ‘passport’,
Step-10
Route/api.php
Route::get(‘/file_name’,’FileController@index’);
If Require then———————
install guzzle pakages-
composer require guzzlehttp/guzzle~6.5.0 If Require then————
app/Http/Kernel.php
‘client_credentials’ => \Laravel\Passport\Http\Middleware\CheckClientCredentials::class,
==========================================================================================
when we create microservice we must do one thing,that env name app.php shold be same
for Example-
in env
ADD_STUDENT_DATA_URL=/api/add_studentDetails
in app.php
‘ADD_STUDENT_DATA_URL’ => env(‘ADD_STUDENT_DATA_URL’, ‘not found in .env file’),
===================================================================================================
==================================================================================================
In Client Microservice
============================================
Add Microservice Controller
class MicroserviceController extends Controller
{
private static function getCategoryAccessToken() {
Log::info('In MicroserviceController ->getCategoryAccessToken()');
try {
Log::info('CRUD_M_BASE_URL:'. Config::get('app.CRUD_M_BASE_URL'));
Log::info('CRUD_M_GRANT_TYPE: ' . Config::get('app.CRUD_M_GRANT_TYPE'));
Log::info('CRUD_M_OAUTH_TOKEN_URL: ' . Config::get('app.CRUD_M_OAUTH_TOKEN_URL'));
Log::info('CRUD_M_CLIENT_SECRET: ' . Config::get('app.CRUD_M_CLIENT_SECRET'));
Log::info('Getting the token!');
$http = new Client(); //GuzzleHttp\Client
Log::info('after client the token!');
Log::info('before post client the token!');
$response = $http->post(
'http://ajaxwithjquery/crud_in_ajax/oauth/token',
[
'form_params' => [
'grant_type' => Config::get('app.CRUD_M_GRANT_TYPE'),
'client_id' => Config::get('app.CRUD_M_CLIENT_ID'),
'client_secret' => Config::get('app.CRUD_M_CLIENT_SECRET'),
'redirect_uri' => '',
],
]
);
Log::info('after post client the token!');
$array = $response->getBody()->getContents();
$json = json_decode($array, true);
$collection = collect($json);
$access_token = $collection->get('access_token');
Log::info('Got the token!');
return $access_token;
} catch (RequestException $e) {
Log::info('There is some exception in MicroserviceController ->getCategoryAccessToken()');
return $e->getResponse()->getStatusCode() . ': ' . $e->getMessage();
}
}
