When using Guzzle library in PHP, you can handle exceptions and errors using try-catch blocks and the Guzzle exception classes. Here's a step-by-step guide on how to handle Guzzle exceptions and errors in PHP:
Install Guzzle if you haven't already: Install Guzzle by running the following command in the terminal:
composer require guzzlehttp/guzzle
Import the necessary classes: Add the following lines at the top of your PHP file to import the required Guzzle classes:
use GuzzleHttp\Client;
use GuzzleHttp\Exception\GuzzleException;
use GuzzleHttp\Exception\RequestException;
use GuzzleHttp\Exception\ServerException;
use GuzzleHttp\Exception\ClientException;
Create a Guzzle client: Instantiate a Guzzle client by creating an instance of the Client class. You can pass any configuration options to the constructor if required.
Send a request and handle exceptions: Use a try-catch block to send a request and handle any exceptions that may occur. For example:
try {
$response = $client->request('GET', 'https://api.example.com/endpoint');
// Process the successful response
echo $response->getStatusCode();
echo $response->getBody();
} catch (ClientException $e) {
// Handle client errors (4xx status codes)
echo $e->getRequest();
echo $e->getResponse();
} catch (ServerException $e) {
// Handle server errors (5xx status codes)
echo $e->getRequest();
echo $e->getResponse();
} catch (RequestException $e) {
// Handle other request exceptions (e.g. network connectivity issues)
echo $e->getRequest();
if ($e->hasResponse()) {
echo $e->getResponse();
}
} catch (GuzzleException $e) {
// Handle other Guzzle exceptions
echo $e->getMessage();
} catch (\Exception $e) {
// Handle generic exceptions
echo $e->getMessage();
}
In the catch blocks, you can access the request and response objects using the methods provided by the corresponding exception classes. Handle the exceptions based on your application's requirements.
Handle HTTP errors using the response object: Additionally, you can handle specific HTTP error codes by checking the status code of the response object. For example:
$statusCode = $response->getStatusCode();
if ($statusCode === 404) {
// Handle the 404 error
} elseif ($statusCode === 500) {
// Handle the 500 error
} else {
// Handle other error codes
}
By following these steps, you can effectively handle Guzzle exceptions and errors in your PHP code.
