How to get all paginated data using guzzle promise - php

I am using guzzle for getting post of a single page and it is working fine. But now the problem is page has pagination 20 post on each page. i want to get all the posts. How can I do it by using guzzle ?
here is my code:
public function __construct()
{
$this->client = new Client([
'base_uri' => 'https://xxxxxx.com/',
'Content-Type' => 'application/json',
]);
}
public function post($post)
{
$response = $this->client->request('GET', $post);
$output = $response->getBody()->getContents();
$data = $this->getData($output);
return $data;
}

There is no way to do it in general. HTTP as a protocol doesn't specify anything about pagination. So depends on the server you work with. Usually the response contains something like
{
"page": 5,
"total": 631
}
Based on this info you can create an URL for the next page by adding ?page=6 (also depends on the server) and request it.

Guzzle is sending requests synchronously

I am using Guzzle to consume a SOAP API. I have to make 6 requests, but in the future this might be even an indeterminate amount of requests.
Problem is that the requests are being send sync, instead of async. Every request on it's own takes +-2.5s. When I send all 6 requests paralell (at least thats what I am trying) it takes +- 15s..
I tried all the examples on Guzzle, the one with a fixed array with $promises, and even the pool (which I need eventually). When I put everything in 1 file (functional) I manage to get the total timing back to 5-6s (which is OK right?). But when I put everything in Objects and functions somehow I do something that makes Guzzle decide to do them sync again.
Checks.php:
public function request()
{
$promises = [];
$promises['requestOne'] = $this->requestOne();
$promises['requestTwo'] = $this->requestTwo();
$promises['requestThree'] = $this->requestThree();
// etc
// wait for all requests to complete
$results = \GuzzleHttp\Promise\settle($promises)->wait();
// Return results
return $results;
}
public function requestOne()
{
$promise = (new API\GetProposition())
->requestAsync();
return $promise;
}
// requestTwo, requestThree, etc
API\GetProposition.php
public function requestAsync()
{
$webservice = new Webservice();
$xmlBody = '<some-xml></some-xml>';
return $webservice->requestAsync($xmlBody, 'GetProposition');
}
Webservice.php
public function requestAsync($xmlBody, $soapAction)
{
$client = new Client([
'base_uri' => 'some_url',
'timeout' => 5.0
]);
$xml = '<soapenv:Envelope>
<soapenv:Body>
'.$xmlBody.'
</soapenv:Body>
</soapenv:Envelope>';
$promise = $client->requestAsync('POST', 'NameOfService', [
'body' => $xml,
'headers' => [
'Content-Type' => 'text/xml',
'SOAPAction' => $soapAction, // SOAP Method to post to
],
]);
return $promise;
}
I changed the XML and some of the parameters for abbreviation. The structure is like this, because I eventually have to talk against multiple API's, to thats why I have a webservice class in between that does all the preparation needed for that API. Most API's have multiple methods/actions that you can call, so that why I have something like. API\GetProposition.
Before the ->wait() statement I can see all $promises pending. So it looks like there are being send async. After ->wait() they have all been fulfilled.
It's all working, minus the performance. All 6 requests don't take more then 2.5 to max 3s.
Hope someone can help.

The problem was that the $client object was created with every request. Causing the curl multi curl not to be able to know which handler to use.
Found the answer via https://stackoverflow.com/a/46019201/7924519.

Created Request using die() also dies the Request caller

I don't know if it's the right terms to employ...
I made an API, in which the answer is sent by the die() function, to avoid some more useless calculations and/or functions calls.
example :
if (isset($authorize->refusalReason)) {
die ($this->api_return(true, [
'resultCode' => $authorize->resultCode,
'reason' => $authorize->refusalReason
]
));
}
// api_return method:
protected function api_return($error, $params = []) {
$time = (new DateTime())->format('Y-m-d H:i:s');
$params = (array) $params;
$params = ['error' => $error, 'date_time' => $time] + $params;
return (Response::json($params)->sendHeaders()->getContent());
}
But my website is based on this API, so I made a function to create a Request and return the contents of it, based on its URI, method, params, and headers:
protected function get_route_contents($uri, $type, $params = [], $headers = []) {
$request = Request::create($uri, $type, $params);
if (Auth::user()->check()) {
$request->headers->set('S-token', Auth::user()->get()->Key);
}
foreach ($headers as $key => $header) {
$request->headers->set($key, $header);
}
// things to merge the Inputs into the new request.
$originalInput = Request::input();
Request::replace($request->input());
$response = Route::dispatch($request);
Request::replace($originalInput);
$response = json_decode($response->getContent());
// This header cancels the one there is in api_return. sendHeaders() makes Content-Type: application/json
header('Content-Type: text/html');
return $response;
}
But now when I'm trying to call an API function, The request in the API dies but dies also my current Request.
public function postCard($token) {
$auth = $this->get_route_contents("/api/v2/booking/payment/card/authorize/$token", 'POST', Input::all());
// the code below is not executed since the API request uses die()
if ($auth->error === false) {
return Redirect::route('appts')->with(['success' => trans('messages.booked_ok')]);
}
return Redirect::back()->with(['error' => $auth->reason]);
}
Do you know if I can handle it better than this ? Any suggestion of how I should turn my code into ?
I know I could just use returns, but I was always wondering if there were any other solutions. I mean, I want to be better, so I wouldn't ask this question if I knew for sure that the only way of doing what I want is using returns.
So it seems that you are calling an API endpoint through your code as if it is coming from the browser(client) and I am assuming that your Route:dispatch is not making any external request(like curl etc)
Now There can be various approaches to handle this:
If you function get_route_contents is going to handle all the requests, then you need to remove the die from your endpoints and simply make them return the data(instead of echoing). Your this "handler" will take care of response.
Make your Endpoint function to have an optional parameter(or some property set in the $request variable), which will tell the function that this is an internal request and data should be returned, when the request comes directly from a browser(client) you can do echo
Make an external call your code using curl etc(only do this if there is no other option)

Send raw json HTTP request for an API call in Yii 1.x.x

I asked a similar question earlier, in a nutshell I have an API application that takes json requests and outputs an json response.
For instance here is one of the requests that I need to test out, how can I use this json object with my testing to emulate a 'real request'
{
"request" : {
"model" : {
"code" : "PR92DK1Z"
}
}
The response is straightforward (this bit has been done).
From other users on here this is the optimised method using Yii to do this, I am just unsure how to emulate the json request - e.g essentially send a JSON HTTP request, can anyone assist on how to do this?
public function actionMyRequest() {
// somehow add my json request...
$requestBody = Yii::app()->request->getRawBody();
$parsedRequest = CJSON::decode($requestBody);
$code = $parsedRequest["request"]["model"]["code"];
}
I don't understand if you want your app to send an http request and get the result or at the opposite receive a http request
I answered for the first assumption, I'll change my answer if you want the other
For me the best way to send an HTTP request is to use Guzzle http client.
This is not a yii extension, but you can use third party libraries with yii.
Here's an example from Guzzle page:
$client = new GuzzleHttp\Client();
$res = $client->get('https://api.github.com/user', [
'auth' => ['user', 'pass']
]);
echo $res->getStatusCode(); // 200
echo $res->getHeader('content-type'); // 'application/json; charset=utf8'
echo $res->getBody();
So in your case you could do something like:
public function actionMyRequest() {
$client = new GuzzleHttp\Client();
$res = $client->get('https://api.your-url.com/');
$requestBody = $res->getBody();
$parsedRequest = CJSON::decode($requestBody);
$code = $parsedRequest["request"]["model"]["code"];
}

Doing HTTP requests FROM Laravel to an external API

What I want is get an object from an API with a HTTP (eg, jQuery's AJAX) request to an external api. How do I start? I did research on Mr Google but I can't find anything helping.
Im starting to wonder is this is even possible?
In this post Laravel 4 make post request from controller to external url with data it looks like it can be done. But there's no example nor any source where to find some documentation.
Please help me out?
Based upon an answer of a similar question here:
https://stackoverflow.com/a/22695523/1412268
Take a look at Guzzle
$client = new GuzzleHttp\Client();
$res = $client->get('https://api.github.com/user', ['auth' => ['user', 'pass']]);
echo $res->getStatusCode(); // 200
echo $res->getBody(); // { "type": "User", ....
We can use package Guzzle in Laravel, it is a PHP HTTP client to send HTTP requests.
You can install Guzzle through composer
composer require guzzlehttp/guzzle:~6.0
Or you can specify Guzzle as a dependency in your project's existing composer.json
{
"require": {
"guzzlehttp/guzzle": "~6.0"
}
}
Example code in laravel 5 using Guzzle as shown below,
use GuzzleHttp\Client;
class yourController extends Controller {
public function saveApiData()
{
$client = new Client();
$res = $client->request('POST', 'https://url_to_the_api', [
'form_params' => [
'client_id' => 'test_id',
'secret' => 'test_secret',
]
]);
echo $res->getStatusCode();
// 200
echo $res->getHeader('content-type');
// 'application/json; charset=utf8'
echo $res->getBody();
// {"type":"User"...'
}
You just want to call an external URL and use the results? PHP does this out of the box, if we're talking about a simple GET request to something serving JSON:
$json = json_decode(file_get_contents('http://host.com/api/stuff/1'), true);
If you want to do a post request, it's a little harder but there's loads of examples how to do this with curl.
So I guess the question is; what exactly do you want?
As of Laravel v7.X, the framework now comes with a minimal API wrapped around the Guzzle HTTP client. It provides an easy way to make get, post, put, patch, and delete requests using the HTTP Client:
use Illuminate\Support\Facades\Http;
$response = Http::get('http://test.com');
$response = Http::post('http://test.com');
$response = Http::put('http://test.com');
$response = Http::patch('http://test.com');
$response = Http::delete('http://test.com');
You can manage responses using the set of methods provided by the Illuminate\Http\Client\Response instance returned.
$response->body() : string;
$response->json() : array;
$response->status() : int;
$response->ok() : bool;
$response->successful() : bool;
$response->serverError() : bool;
$response->clientError() : bool;
$response->header($header) : string;
$response->headers() : array;
Please note that you will, of course, need to install Guzzle like so:
composer require guzzlehttp/guzzle
There are a lot more helpful features built-in and you can find out more about these set of the feature here: https://laravel.com/docs/7.x/http-client
This is definitely now the easiest way to make external API calls within Laravel.
Updated on March 21 2019
Add GuzzleHttp package using composer require guzzlehttp/guzzle:~6.3.3
Or you can specify Guzzle as a dependency in your project's composer.json
{
"require": {
"guzzlehttp/guzzle": "~6.3.3"
}
}
Include below line in the top of the class where you are calling the API
use GuzzleHttp\Client;
Add below code for making the request
$client = new Client();
$res = $client->request('POST', 'http://www.exmple.com/mydetails', [
'form_params' => [
'name' => 'george',
]
]);
if ($res->getStatusCode() == 200) { // 200 OK
$response_data = $res->getBody()->getContents();
}
Definitively, for any PHP project, you may want to use GuzzleHTTP for sending requests.
Guzzle has very nice documentation you can check here.
I just want to say that, you probably want to centralize the usage of the Client class of Guzzle in any component of your Laravel project (for example a trait) instead of being creating Client instances on several controllers and components of Laravel (as many articles and replies suggest).
I created a trait you can try to use, which allows you to send requests from any component of your Laravel project, just using it and calling to makeRequest.
namespace App\Traits;
use GuzzleHttp\Client;
trait ConsumesExternalServices
{
/**
* Send a request to any service
* #return string
*/
public function makeRequest($method, $requestUrl, $queryParams = [], $formParams = [], $headers = [], $hasFile = false)
{
$client = new Client([
'base_uri' => $this->baseUri,
]);
$bodyType = 'form_params';
if ($hasFile) {
$bodyType = 'multipart';
$multipart = [];
foreach ($formParams as $name => $contents) {
$multipart[] = [
'name' => $name,
'contents' => $contents
];
}
}
$response = $client->request($method, $requestUrl, [
'query' => $queryParams,
$bodyType => $hasFile ? $multipart : $formParams,
'headers' => $headers,
]);
$response = $response->getBody()->getContents();
return $response;
}
}
Notice this trait can even handle files sending.
If you want more details about this trait and some other stuff to integrate this trait to Laravel, check this article. Additionally, if interested in this topic or need major assistance, you can take my course which guides you in the whole process.
I hope it helps all of you.
Best wishes :)
Basic Solution for Laravel 8 is
use Illuminate\Support\Facades\Http;
$response = Http::get('http://example.com');
I had conflict between "GuzzleHTTP sending requests" and "Illuminate\Http\Request;" don't ask me why... [it's here to be searchable]
So looking for 1sec i found in Laravel 8 Doc...
**Guzzle is inside the Laravel 8 Http Request !**
https://laravel.com/docs/8.x/http-client#making-requests
as you can see
https://laravel.com/docs/8.x/http-client#introduction
Laravel provides an expressive, minimal API around the Guzzle HTTP
client, allowing you to quickly make outgoing HTTP requests to
communicate with other web applications. Laravel's wrapper around
Guzzle is focused on its most common use cases and a wonderful
developer experience.
It worked for me very well, have fun and if helpful point up!
I also created trait similar to #JuanDMeGonthat's that u can use anywhere in your project.Please check this out
trait ApiRequests
{
public function get($url, $data = null)
{
try {
$response = Http::get($this->base_url . $url, $data);
} catch (\Exception $e) {
info($e->getMessage());
abort(503);
}
if ( $response->status() == 401) {
throw new AuthenticationException();
} else if (! $response->successful()) {
abort(503);
}
return $response->json();
}
public function post($url, $data = [])
{
$token = session()->get('token');
try {
$response = Http::acceptJson()->withToken($token)->post($this->base_url . $url, $data);
} catch (\Exception $e) {
abort(503);
}
if ($response->status() == 401 && !request()->routeIs('login')) {
throw new AuthenticationException();
}
return $response;
}
}
class Controller extends BaseController
{
protected $base_url;
use AuthorizesRequests, DispatchesJobs, ValidatesRequests, ApiRequests;
public function __construct()
{
$this->base_url = env("BASE_URL","http://192.168.xxxxxxx");
View::share('base_url', $this->base_url);
}
}
You can use Httpful :
Website : http://phphttpclient.com/
Github : https://github.com/nategood/httpful
Here is the simple call for laravel 9.4
Route::get('/currency', function () {
$response = Http::withHeaders([
'x-api-key' => 'prtl6749387986743898559646983194',
])->get('https://partners.api.skyscanner.net/apiservices/v3/culture/currencies');
return response()->json(['status'=> true,'data'=> json_decode($response->body()), 'Message'=>"Currency retrieved successfully"], 200);
});
Don't forget to import
use Illuminate\Support\Facades\Http;

Laravel - POST data is null when using external request

I'm new to laravel, and I'm trying to implement a simple rest api.
I have the controller implemented, and tested via unit testing.
My problem is with the POST request.
Via the tests Input:json has data, via an external rest client it returns null.
This is the code on the unit test
$newMenu = array(
'name'=>'Christmas Menu',
'description'=>'Christmas Menu',
'img_url'=>'http://www.example.com',
'type_id'=>1,
);
Request::setMethod('POST');
Input::$json = $newMenu;
$response = Controller::call('menu#index');
What am I doing wrong?
UPDATE:
This is realy driving me crazy
I've instanciated a new laravel project and just have this code:
Routes
Route::get('test', 'home#index');
Route::post('test', 'home#index');
Controller:
class Home_Controller extends Base_Controller {
public $restful = true;
public function get_index()
{
return Response::json(['test'=>'hello world']);
}
public function post_index()
{
return Response::json(['test'=>Input::all()]);
}
}
CURL call:
curl -H "Accept:application/json" -H"Content-type: application/json" -X POST -d '{"title":"world"}' http://localhost/laravel-post/public/test
response:
{"test":[]}
Can anyone point me to what is wrong.
This is really preventing me to use laravel, and I really liked the concept.
Because you are posting JSON as your HTTP body you don't get it with Input::all();
You should use:
$postInput = file_get_contents('php://input');
$data = json_decode($postInput, true);
$response = array('test' => $data);
return Response::json($response);
Also you can use
Route::any('test', 'home#index');
instead of
Route::get('test', 'home#index');
Route::post('test', 'home#index');
Remove header Content-type: application/json if you are sending it as key value pairs and not a json
If you use : Route::post('test', 'XYZController#test');
Send data format : Content-type : application/json
For example : {"data":"foo bar"}
And you can get the post (any others:get, put...etc) data with :
Input::get('data');
This is clearly written in here : http://laravel.com/docs/requests
. Correct Content-type is very important!
I am not sure your CURL call is correct. Maybe this can be helpful : How to POST JSON data with Curl from Terminal/Commandline to Test Spring REST?
I am using Input::get('data') and it works.
I was facing this problem, my response of post was always null. To solve that I put the body key in guzzle object, like this
$client = new Client([
'headers' => [
'Content-Type' => 'application/json',
'Authorization' => config('app.callisto_token'),
]
]);
$body = [
'firstResult'=> 0,
'data' => '05/05/2022'
];
$response = $client->post('http://'.$this->ip.'/IntegracaoERP'.'/status_pedido',
['body' => json_encode($body)]
);
Don't forget the json_encode in body key.
Hope this helps.
