Back end to Back end API request and response - laravel

I have an app built on laravel 8 with a Vue Spa front end, using Sanctum.
I have a controller method that requests from another Laravel project (using its Sanctum API) so essentially, the Spa requests from Laravel 1, which requests from Laravel 2 project.
Following the responses from L2 project back, the Controller method on L2 is:
public function popular(Request $request)
{
$limit = 20;
if ($request->has('limit')) {
$limit = $request->limit;
}
$perPage = 20;
if ($request->has('per_page')) {
$limit = $request->per_page;
}
if ($request->has('page')) {
$articles = $request
->user()
->articles()
->activeArticles()
->select('articles.uuid', 'articles.title')
->orderBy('articles.views', 'DESC')
->simplePaginate($perPage);
} else {
$articles = $request
->user()
->articles()
->activeArticles()
->select('articles.uuid', 'articles.title')
->orderBy('articles.views', 'DESC')
->limit($limit)
->get();
}
return $articles;
}
This response is received by L1 Controller method, and sent back to the Spa like this:
public function popular(Request $request)
{
$apiEndPoint = self::$apiBaseUrl . '/article/popular';
$response = self::$httpRequest->get($apiEndPoint, $request->query());
if (!$response->successful()) {
return $this->setMessage(trans('help.api_error'))->send();
}
$body = $response->getBody();
return response(['data' => $body]);
}
With this return:
return response(['data' => $body]);
I get and empty data object:
{
data: {}
}
And with this return:
return response($body);
I get the payload as text / string:
[{"id":15,"uuid":"c6082143-0f34-443b-9447-3fa57ed73f48","name":"dashboard","icon":"database","active":1,"owned_by":2,"product_id":4,"created_at":"2021-12-23T11:46:35.000000Z","updated_at":"2021-12-23T11:46:35.000000Z"},{"id":16,
How do I return the $body as JSON to the Spa?
UPDATE: I tried suggestions below, but the result is still exception.
return response()->json($body);
Returns:
"message": "json_decode(): Argument #1 ($json) must be of type string, GuzzleHttp\\Psr7\\Stream given",
So getting the body in getBody() returns a string I understood.
If I Log the $body I get:
$body = $response->getBody();
Log::info($body);
[2021-12-25 23:15:36] local.INFO: {"current_page":2,"data":[{"uuid":"aa4a47bf-4975-4e78-868a-103398934504","title":"Ritchie-Hoeger"},
Thanks for any help and happy festive season.

API Responser
First create a trait in laravel in 'app\Traits\ApiResponser.php'
<?php
namespace App\Traits;
use Carbon\Carbon;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Auth;
trait ApiResponser{
public function set_response($data, $status_code, $status, $details)
{
$resData = response(json_encode(
[
'status' => $status, // true or false
'code' => $status_code,
'data' => $data,
'message' => $details
]
), 200)
->header('Content-Type', 'application/json');
$data = [];
return $resData;
}
}
Second in any controller call this trait's function set_response()
<?php
namespace App\Http\Controllers;
use App\Models\User;
use App\Traits\ApiResponser;
use Illuminate\Http\Request;
class ListController extends Controller
{
use ApiResponser;
public function getAllUserList(Request $request)
{
$data = User::select('id', 'name', 'email')->get();
return $this->set_response(['data' => $data], 200,'success', ['User list']);
}
}
Output will be like this

use the json helper function
return response()->json($body);
or
use Response;
return Response::json($body);
This will create an instance of \Illuminate\Routing\ResponseFactory. See the phpDocs for possible parameters below:
/**
* Return a new JSON response from the application.
*
* #param string|array $data
* #param int $status
* #param array $headers
* #param int $options
* #return \Symfony\Component\HttpFoundation\Response
* #static
*/
public static function json($data = array(), $status = 200, $headers = array(), $options = 0){
return \Illuminate\Routing\ResponseFactory::json($data, $status, $headers, $options);
}

I needed to ->getContents() after the ->getBody()
$body = $response->getBody()->getContents();
All good again...

paginate method for data obtained from external api

I'm wondering if it is possible to automate the pagination process for data obtained from external API like
$users = App\User::paginate(15);
for models. Maybe do you know any packages? I want to make something like that
$client = new \GuzzleHttp\Client();
$res = $client->request('GET', 'https://xxx');
$data = $res->getBody();
$res = json_decode($data );
///pagination
Do you know any solutions? Is the only one way to create pagination manually?
You could use Laravel resource.
First: create a single resource (I suppose your API is about Post)
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\JsonResource;
class Post extends JsonResource
{
/**
* Transform the resource into an array.
*
* #param \Illuminate\Http\Request $request
* #return array
*/
public function toArray($request)
{
return [
'name' => $this->resource['name'],
'title' => $this->resource['title']
];
}
}
Second: create a resource collection
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\ResourceCollection;
class PostCollection extends ResourceCollection
{
public function toArray($request)
{
return [
'data' => $this->collection
->map
->toArray($request)
->all(),
'links' => [
'self' => 'link-value',
],
];
}
}
after that you could set your api data to collection like this:
$client = new \GuzzleHttp\Client();
$res = $client->request('GET', 'https://xxx');
$data = $res->getBody();
$res = collect(json_decode($data));
return PostCollection::make($res);
and for add pagination to your resource collection you could do this:
$res = collect(json_decode($data));
$page = request()->get('page');
$perPage = 10;
$paginator = new LengthAwarePaginator(
$res->forPage($page, $perPage), $res->count(), $perPage, $page
);
return PostCollection::make($paginator);

L5 Using Hashid in middleware returns null

I am using hashid to hash the id parameters in url. I have it set up in my model to automatically hash the id. This is working fine. My problem is decoding the hash in a middleware returns null. I'm not sure if this is a problem with my middleware or because of the hashing.
Model:
public function getIdAttribute($value)
{
$hashids = new \Hashids\Hashids(env('APP_KEY'),10);
return $hashids->encode($value);
}
Middleware:
<?php
namespace App\Http\Middleware;
use Closure;
class HashIdsDecode
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle($request, Closure $next)
{
dd($request->id); //Returns null on show method - example localhost:8000/invoices/afewRfshTl
if($request->has('id'))
{
$hashids = new \Hashids\Hashids(env('APP_KEY'),10);
dd($hashids->decode($request->input('id')));
}
return $next($request);
}
}
Route:
Route::resource('invoices','InvoiceController');
Controller:
public function show($id)
{
$invoice = Invoice::find($id);
return view('invoices.show', [
'invoice' => $invoice,
'page_title' => ' Invoices',
'page_description' => 'View Invoice',
]);
}
NOTE: if I bypass the middleware and do it directly in my controller like this it works but it requires me to repeat myself over and over and probably not the best way to do it.
public function show($id)
{
$hashids = new \Hashids\Hashids(env('APP_KEY'),10);
$invoiceId = $hashids->decode($id)[0];
$invoice = Invoice::find($invoiceId);
return view('invoices.show', [
'invoice' => $invoice,
'page_title' => ' Invoices',
'page_description' => 'View Invoice',
]);
}
Personally, I would be more inclined to write a model trait. You can then use the trait on only the models required, rather than assuming every ID argument in a request is a Hash ID.
E.g.
namespace App\Models\Traits;
use Hashids\Hashids;
use Illuminate\Database\Eloquent\Builder;
trait HashedId
{
public function scopeHashId(Builder $query, $id)
{
$hashIds = new Hashids(env('APP_KEY'), 10);
$id = $hashIds->decode($id)[0];
return $query->where('id', $id);
}
}
Then to use it, you'd use the trait on your Invoice model (edit):
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Invoice extends Model
{
use \App\Models\Traits\HashedId;
// ...
}
And execute the following query in your controller:
public function show($id)
{
$invoice = Invoice::hashId($id)->firstOrFail();
return view('invoices.show', [
'invoice' => $invoice,
'page_title' => ' Invoices',
'page_description' => 'View Invoice',
]);
}

Validation fileds from ajax request [Laravel 5]

Here is my validation request :rules
<?php
namespace App\Http\Requests;
use App\Http\Requests\Request;
use Illuminate\Support\Facades\Auth;
class UpdateCommentRequest extends Request {
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize() {
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules() {
$user = Auth::user()->id;
return [
'comment' => 'required|between:15,600',
'projectID' => "required|exists:project_group,project_id,user_id,$user|numeric",
'order' => "required|numeric",
'level' => "required|numeric"
];
}
}
And in my model I have like this:
public function apiUpdateComment(UpdateCommentRequest $request){
$comment = Comment::find(Input::get("order"));
$comment->text = Input::get('comment');
if($comment->save()){
return 'success';
}
}
This fileds I need to validate agins rules array:
array(
'comment' => Input::get('comment'),
'projectID' => Input::get('projectID'),
'order' => Input::get("order"),
'level' => Input::get("level"),
);
I need to check if all rules are ok and then update comment... Anyone can help?
public function apiUpdateComment(UpdateCommentRequest $request){
$comment = Comment::find($request->get("order"));
$comment->text = $request->get('comment');
if($comment->save()){
return 'success';
}
}
The logic behind the code:
A post request is send the the server and the route file sends it the the apiUpdateComment with all variables inside the $request. But before the code of the function is executed the validator checks the rules in your UpdateCommentRequest. If the test fails it will return errors. If it pass a comment with the id will be updated.

L5 Paypal Integration - Finding Controller method

I am trying to integrate Paypal into my Laravel 5 site using this package:
http://packalyst.com/packages/package/netshell/paypal
When I go to: /paypal/checkout though, I get this error:
InvalidArgumentException in UrlGenerator.php line 561: Action
App\Http\Controllers\PayPalController#getDone not defined.
This is my route:
Route::get('/paypal/checkout', [
'as' => 'get-paypal-checkout', 'uses' => 'PayPalController#getCheckout'
]);
And this is the PayPalController:
<?php namespace App\Http\Controllers;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Paypal;
use Redirect;
use Illuminate\Http\Request;
class PayPalController extends Controller {
private $_apiContext;
public function __construct() {
$this->_apiContext = PayPal::ApiContext(
config('services.paypal.client_id'),
config('services.paypal.secret'));
$this->_apiContext->setConfig(array(
'mode' => 'sandbox',
'service.EndPoint' => 'https://api.sandbox.paypal.com',
'http.ConnectionTimeOut' => 30,
'log.LogEnabled' => true,
'log.FileName' => storage_path('logs/paypal.log'),
'log.LogLevel' => 'FINE'
));
}
public function getCheckout() {
$payer = PayPal::Payer();
$payer->setPaymentMethod('paypal');
$amount = PayPal:: Amount();
$amount->setCurrency('EUR');
$amount->setTotal(42); // This is the simple way,
// you can alternatively describe everything in the order separately;
// Reference the PayPal PHP REST SDK for details.
$transaction = PayPal::Transaction();
$transaction->setAmount($amount);
$transaction->setDescription('What are you selling?');
$redirectUrls = PayPal:: RedirectUrls();
$redirectUrls->setReturnUrl(action('PayPalController#getDone'));
$redirectUrls->setCancelUrl(action('PayPalController#getCancel'));
$payment = PayPal::Payment();
$payment->setIntent('sale');
$payment->setPayer($payer);
$payment->setRedirectUrls($redirectUrls);
$payment->setTransactions(array($transaction));
$response = $payment->create($this->_apiContext);
$redirectUrl = $response->links[1]->href;
return Redirect::to( $redirectUrl );
}
public function getDone(Request $request) {
$id = $request->get('paymentId');
$token = $request->get('token');
$payer_id = $request->get('PayerID');
$payment = PayPal::getById($id, $this->_apiContext);
$paymentExecution = PayPal::PaymentExecution();
$paymentExecution->setPayerId($payer_id);
$executePayment = $payment->execute($paymentExecution, $this->_apiContext);
// Clear the shopping cart, write to database, send notifications, etc.
// Thank the user for the purchase
return view('checkout.done');
}
public function getCancel() {
// Curse and humiliate the user for cancelling this most sacred payment (yours)
return view('checkout.cancel');
}
}
Any help would be appreciated.
Thanks
Although laravel allows you to generate url's to actions. I researched what happened in the code.
In the UrlGenerator class:
/**
* Get the URL to a controller action.
*
* #param string $action
* #param mixed $parameters
* #param bool $absolute
* #return string
*
* #throws \InvalidArgumentException
*/
public function action($action, $parameters = [], $absolute = true)
{
if ($this->rootNamespace && !(strpos($action, '\\') === 0)) {
$action = $this->rootNamespace.'\\'.$action;
} else {
$action = trim($action, '\\');
}
if (!is_null($route = $this->routes->getByAction($action))) {
return $this->toRoute($route, $parameters, $absolute);
}
throw new InvalidArgumentException("Action {$action} not defined.");
}
It will search for a defined route with the specified action and in fact returns a link based on that route. So you would have to define the route to PayPayController#getDone for it to work.

Laravel 5 how to validate route parameters?

I want to validate the route parameters in the "form request" but don't know how to do it.
Below is the code sample, I am trying with:
Route
// controller Server
Route::group(['prefix' => 'server'], function(){
Route::get('checkToken/{token}',['as'=>'checkKey','uses'=> 'ServerController#checkToken']);
});
Controller
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Http\Requests;
class ServerController extends Controller {
public function checkToken( \App\Http\Requests\CheckTokenServerRequest $request) // OT: - why I have to set full path to work??
{
$token = Token::where('token', '=', $request->token)->first();
$dt = new DateTime;
$token->executed_at = $dt->format('m-d-y H:i:s');
$token->save();
return response()->json(json_decode($token->json),200);
}
}
CheckTokenServerRequest
namespace App\Http\Requests;
use App\Http\Requests\Request;
class CheckTokenServerRequest extends Request {
//autorization
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'token' => ['required','exists:Tokens,token,executed_at,null']
];
}
}
But when I try to validate a simple url http://myurl/server/checkToken/222, I am getting the response: no " token " parameter set.
Is it possible to validate the parameters in a separate "Form request", Or I have to do all in a controller?
ps. Sorry for my bad English.
For Laravel < 5.5:
The way for this is overriding all() method for CheckTokenServerRequest like so:
public function all()
{
$data = parent::all();
$data['token'] = $this->route('token');
return $data;
}
EDIT
For Laravel >= 5.5:
Above solution works in Laravel < 5.5. If you want to use it in Laravel 5.5 or above, you should use:
public function all($keys = null)
{
$data = parent::all($keys);
$data['token'] = $this->route('token');
return $data;
}
instead.
Override the all() function on the Request object to automatically apply validation rules to the URL parameters
class SetEmailRequest
{
public function rules()
{
return [
'email' => 'required|email|max:40',
'id' => 'required|integer', // << url parameter
];
}
public function all()
{
$data = parent::all();
$data['id'] = $this->route('id');
return $data;
}
public function authorize()
{
return true;
}
}
Access the data normally from the controller like this, after injecting the request:
$setEmailRequest->email // request data
$setEmailRequest->id, // url data
If you dont want to specify each route param and just put all route params you can override like this:
Laravel < 5.5:
public function all()
{
return array_merge(parent::all(), $this->route()->parameters());
}
Laravel 5.5 or above:
public function all($keys = null)
{
// Add route parameters to validation data
return array_merge(parent::all(), $this->route()->parameters());
}
The form request validators are used for validating HTML form data that are sent to server via POST method. It is better that you do not use them for validating route parameters. route parameters are mostly used for retrieving data from data base so in order to ensure that your token route parameter is correct change this line of your code, from
$token = Token::where('token', '=', $request->token)->first();
to
$token = Token::where('token', '=', $request->input(token))->firstOrFail();
firstOrFail() is a very good function, it sends 404 to your user, if the user insert any invalid token.
you get no " token " parameter set because Laravel assumes that your "token" parameter is a POST data which in your case it is not.
if you insist on validating your "token" parameter, by form request validators you gonna slow down your application, because you perform two queries to your db,
one in here
$token = Token::where('token', '=', $request->token)->first();
and one in here
return [
'token' => ['required','exists:Tokens,token,executed_at,null']
];
I suggest to use firsOrFail to do both validating and retrieving at once.
A trait can cause this validation to be relatively automagic.
Trait
<?php
namespace App\Http\Requests;
/**
* Class RouteParameterValidation
* #package App\Http\Requests
*/
trait RouteParameterValidation{
/**
* #var bool
*/
private $captured_route_vars = false;
/**
* #return mixed
*/
public function all(){
return $this->capture_route_vars(parent::all());
}
/**
* #param $inputs
*
* #return mixed
*/
private function capture_route_vars($inputs){
if($this->captured_route_vars){
return $inputs;
}
$inputs += $this->route()->parameters();
$inputs = self::numbers($inputs);
$this->replace($inputs);
$this->captured_route_vars = true;
return $inputs;
}
/**
* #param $inputs
*
* #return mixed
*/
private static function numbers($inputs){
foreach($inputs as $k => $input){
if(is_numeric($input) and !is_infinite($inputs[$k] * 1)){
$inputs[$k] *= 1;
}
}
return $inputs;
}
}
Usage
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class MyCustomRequest extends FormRequest{
use RouteParameterValidation;
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize(){
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules(){
return [
//
'any_route_param' => 'required'//any rule(s) or custom rule(s)
];
}
}
For \App\Http\Requests\CheckTokenServerRequest you can add use App\Http\Requests\CheckTokenServerRequest; at the top.
If you pass the token by url you can use it likes a variable in controller.
public function checkToken($token) //same with the name in url
{
$_token = Token::where('token', '=', $token)->first();
$dt = new DateTime;
$_token->executed_at = $dt->format('m-d-y H:i:s');
$_token->save();
return response()->json(json_decode($token->json),200);
}
$request->merge(['id' => $id]);
...
$this->validate($request, $rules);
or
$request->merge(['param' => $this->route('param')]);
...
$this->validate($request, $rules);
You just missing the underscore before token. Replace with
_token
wherever you check it against the form generated by laravel.
public function rules()
{
return [
'_token' => ['required','exists:Tokens,token,executed_at,null']
];
FormRequest has a method validationData() that defines what data to use for validation. So just override that one with route parameters in your form request class:
/**
* Use route parameters for validation
* #return array
*/
protected function validationData()
{
return $this->route()->parameters();
}
or leave most of the all logic in place and override input method from trait \Illuminate\Http\Concerns\InteractsWithInput
/**
* Retrieve an input item from the request.
*
* #param string|null $key
* #param string|array|null $default
* #return string|array|null
*/
public function input($key = null, $default = null)
{
return data_get(
$this->getInputSource()->all() + $this->query->all() + $this->route()->parameters(), $key, $default
);
}
