Very beginner question but simply do not know where to begin. I am trying to obtain a response with this API using PHP but cannot get anything to work.
I know the problem has something to do with HTTP Components but I'm a total beginner and very stuck.
Any help would be great or perhaps if there's another (cleaner and easier) way to do this would be great as well.
I am trying to get the response in json format
<?php
// This sample uses the Apache HTTP client from HTTP Components (http://hc.apache.org/httpcomponents-client-ga/)
require_once 'HTTP/Request2.php';
$request = new Http_Request2('https://services.last10k.com/v1/company/{ticker}/ratios');
$url = $request->getUrl();
$headers = array(
// Request headers
'Ocp-Apim-Subscription-Key' => '{subscription key}',
);
$request->setHeader($headers);
$parameters = array(
// Request parameters
);
$url->setQueryVariables($parameters);
$request->setMethod(HTTP_Request2::METHOD_GET);
// Request body
$request->setBody("{body}");
try
{
$response = $request->send();
echo $response->getBody();
}
catch (HttpException $ex)
{
echo $ex;
}
?>

i'm using PHP with Guzzle.
I have this code:
$client = new Client();
$request = new \GuzzleHttp\Psr7\Request('POST', 'http://localhost/async-post/tester.php',[
'headers' => ['Content-Type' => 'application/x-www-form-urlencoded'],
'form_params' => [
'action' => 'TestFunction'
],
]);
$promise = $client->sendAsync($request)->then(function ($response) {
echo 'I completed! ' . $response->getBody();
});
$promise->wait();
For some reason Guzzle Doesn't send the POST Parameters.
Any suggestion?
Thanks :)
I see 2 things.
The parameters have to go as string (json_encode)
And you were also including them as part of the HEADER, not the BODY.
Then i add a function to handle the response as ResponseInterface
$client = new Client();
$request = new Request('POST', 'https://google.com', ['Content-Type' => 'application/x-www-form-urlencoded'], json_encode(['form_params' => ['s' => 'abc',] ]));
/** #var Promise\PromiseInterface $response */
$response = $client->sendAsync($request);
$response->then(
function (ResponseInterface $res) {
echo $res->getStatusCode() . "\n";
},
function (RequestException $e) {
echo $e->getMessage() . "\n";
echo $e->getRequest()->getMethod();
}
);
$response->wait();
In this test Google responds with a
Client error: POST https://google.com resulted in a 405 Method Not Allowed
But is ok. Google doesn't accepts request like this.
Guzzle isn't truely asynchronous. It's more of multi-threading. That is why you have the wait() line to prevent the your current PHP script from closing until all multiple spun threads finish. If you remove the wait() line, the PHP process spun by the script ends immediately with all it's threads and your request is never sent.
Ergo, you need Guzzle (and Curl) for multi-processing(concurrent) I/O and not for asynchronous I/O. In your case, you are processing one request and Guzzle promises are simply an overkill.
To send a request with Guzzle, simply do this:
use GuzzleHttp\Client;
use GuzzleHttp\Psr7\Request;
$client = new Client();
$header = ['Content-Type' => 'application/x-www-form-urlencoded'];
$body = json_encode(['id' => '2', 'name' => 'dan']);
$request = new Request('POST', 'http://localhost/async-post/tester.php', $header, $body);
$response = $client->send($request);
Also, it seems you are using the form action attribute rather than the actual form data in form-params.
I'm posting this answer because I tried to achieve something really asynchronous with php - Schedule I/O processing as a background task, continue processing script and serve the page; I/O continues in background and completes without disrupting the client. Laravel Queues was the best thing I could find.
I am trying to recreate the following Tesco API code using Symfony\Component\HttpFoundation:
<?php
// This sample uses the Apache HTTP client from HTTP Components (http://hc.apache.org/httpcomponents-client-ga/)
require_once 'HTTP/Request2.php';
$request = new Http_Request2('https://dev.tescolabs.com/grocery/products/?query={query}&offset={offset}&limit={limit}');
$url = $request->getUrl();
$headers = array(
// Request headers
'Ocp-Apim-Subscription-Key' => '{subscription key}',
);
$request->setHeader($headers);
$parameters = array(
// Request parameters
);
$url->setQueryVariables($parameters);
$request->setMethod(HTTP_Request2::METHOD_GET);
// Request body
$request->setBody("{body}");
try
{
$response = $request->send();
echo $response->getBody();
}
catch (HttpException $ex)
{
echo $ex;
}
?>
I am new to php in general and I am undertaking my first Symfony project. Could somebody please help me will recreating the above code using Symfony HttpFoundation instead?
I have tried the following code, and I return nothing:
$req2 = Request::create('https://dev.tescolabs.com/grocery/products/?query={query}&offset={offset}&limit={limit}', 'GET');
$req2->headers->set('Ocp-Apim-Subscription-Key', 'my_api_key');
$params = array(
'query' => 'walkers',
'offset' => '0',
'limit' => '10',
);
$req2->query->add($params);
try
{
$response = new Response();
var_dump($response);die;
}
catch (HttpException $ex)
{
die ('EX: '.$ex);
}
Symfony's Request class is used for an incoming request to Symfony. Maybe you should have a look at Guzzle to use an object-oriented approach to create a request or cURL like proposed in Symfony2 - How to perform an external Request
I'm tyring to post something to Googles oAuth server to do some authentication. Google really wants this information in form data (Content-Type: application/x-www-form-urlencoded) but my guzzle client seems to insist (as far as I can tell) on making the body JSON. I'm using Guzzle 4.*
I've changed my URL to a PostCatcher.io url, so I can see what comes out (because for the life of my I can't figure out how to see the actual raw HTTP request that guzzle spits out), and it looks like theres JSON coming out.
My code (I'm using a test url by now):
$client = new GuzzleClient();
$url = "https://www.googleapis.com/" . "oauth2/v3/token";
$test_url = 'http://postcatcher.in/catchers/55602457b92ce203000032ae';
$request = $client->createRequest('POST', $test_url);
$request->setHeader('Content-Type', 'application/x-www-form-urlencoded'); //should be redundant
$body = $request->getBody();
$body->setField('code', $code);
$body->setField('client_id', $this->client_id);
$body->setField('client_secret', $this->client_secret);
$body->setField('redirect_url', $this->redicrect_url);
$body->setField('grant_type', $this->grant_type);
try {
$response = $client->send($request);
$result = $response->getBody();
return $result;
} catch (\Exception $exc) {
return $exc->getCode() . ' ' . $exc->getMessage();
}
The documentation says this should be enough. What am I missing ?
Using Guzzle 5.2 I've done the same thing with:
$request = $this->createRequest(
$method,
$uri,
['body' => $php_array_of_values ]
);
$response = $this->send($request);
I found the problem. I did upgrade to Guzzle 5.* tho I suspect that wasn't actually the solution.
I just neede to look at the response content. So in the exception clause of the call I added:
if ($exc->hasResponse()) {
return $exc->getResponse()->json();
}
Which gave me a clear error message from Google. The error message was "Missing parameter: redirect_uri". And that's because I had written url instead of uri.
Fixed that, and now it's all good.
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"];
}
Using Symfony2, I need to access an external API based on HTTPS.
How can I call an external URI and manage the response to "play" with it. For example, to render a success or a failure message?
I am thinking in something like (note that performRequest is a completely invented method):
$response = $this -> performRequest("www.someapi.com?param1=A¶m2=B");
if ($response -> getError() == 0){
// Do something good
}else{
// Do something too bad
}
I have been reading about Buzz and other clients. But I guess that Symfony2 should be able to do it by its own.
I'd suggest using CURL:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'www.someapi.com?param1=A¶m2=B');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json')); // Assuming you're requesting JSON
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
// If using JSON...
$data = json_decode($response);
Note: The php on your web server must have the php5-curl library installed.
Assuming the API request is returning JSON data, this page may be useful.
This doesn't use any code that is specific to Symfony2. There may well be a bundle that can simplify this process for you, but if there is I don't know about it.
Symfony doesn't have a built-in service for this, but this is a perfect opportunity to create your own, using the dependency injection framework. What you can do here is write a service to manage the external call. Let's call the service "http".
First, write a class with a performRequest() method:
namespace MyBundle\Service;
class Http
{
public function performRequest($siteUrl)
{
// Code to make the external request goes here
// ...probably using cUrl
}
}
Register it as a service in app/config/config.yml:
services:
http:
class: MyBundle\Service\Http
Now your controller has access to a service called "http". Symfony manages a single instance of this class in the "container", and you can access it via $this->get("http"):
class MyController
{
$response = $this->get("http")->performRequest("www.something.com");
...
}
Best client that I know is: http://docs.guzzlephp.org/en/latest/
There is already bundle that integrates it into Symfony2 project:
https://github.com/8p/GuzzleBundle
$client = $this->get('guzzle.client');
// send an asynchronous request.
$request = $client->createRequest('GET', 'http://httpbin.org', ['future' => true]);
// callback
$client->send($request)->then(function ($response) {
echo 'I completed! ' . $response;
});
// optional parameters
$response = $client->get('http://httpbin.org/get', [
'headers' => ['X-Foo-Header' => 'value'],
'query' => ['foo' => 'bar']
]);
$code = $response->getStatusCode();
$body = $response->getBody();
// json response
$response = $client->get('http://httpbin.org/get');
$json = $response->json();
// extra methods
$response = $client->delete('http://httpbin.org/delete');
$response = $client->head('http://httpbin.org/get');
$response = $client->options('http://httpbin.org/get');
$response = $client->patch('http://httpbin.org/patch');
$response = $client->post('http://httpbin.org/post');
$response = $client->put('http://httpbin.org/put');
More info can be found on: http://docs.guzzlephp.org/en/latest/index.html
https://github.com/sensio/SensioBuzzBundle seems to be what you are looking for.
It implements the Kris Wallsmith buzz library to perform HTTP requests.
I'll let you read the doc on the github page, usage is pretty basic:
$buzz = $this->container->get('buzz');
$response = $buzz->get('http://google.com');
echo $response->getContent();
Symfony does not have its own rest client, but as you already mentioned there are a couple of bundles. This one is my prefered one:
https://github.com/CircleOfNice/CiRestClientBundle
$restClient = $this->container->get('ci.restclient');
$restClient->get('http://www.someUrl.com');
$restClient->post('http://www.someUrl.com', 'somePayload');
$restClient->put('http://www.someUrl.com', 'somePayload');
$restClient->delete('http://www.someUrl.com');
$restClient->patch('http://www.someUrl.com', 'somePayload');
$restClient->head('http://www.someUrl.com');
$restClient->options('http://www.someUrl.com', 'somePayload');
$restClient->trace('http://www.someUrl.com');
$restClient->connect('http://www.someUrl.com');
You send the request via
$response = $restclient->get($url);
and get a Symfony response object.
Then you can get the status code via
$httpCode = $response-> getStatusCode();
Your code would look like:
$restClient = $this->container->get('ci.restclient');
if ($restClient->get('http://www.yourUrl.com')->getStatusCode !== 200) {
// no error
} else {
// error
}
Use the HttpClient class to create the low-level HTTP client that makes requests, like the following GET request:
use Symfony\Component\HttpClient\HttpClient;
$client = HttpClient::create();
$response = $client->request('GET', 'https://api.github.com/repos/symfony/symfony-docs');
$statusCode = $response->getStatusCode();
// $statusCode = 200
$contentType = $response->getHeaders()['content-type'][0];
// $contentType = 'application/json'
$content = $response->getContent();
// $content = '{"id":521583, "name":"symfony-docs", ...}'
$content = $response->toArray();
// $content = ['id' => 521583, 'name' => 'symfony-docs', ...]
This is compatible with Symfony 5. Symfony Manual on this topic: The HttpClient Component
