Guzzle: Handle 400 Bad Request

Guzzle: handle 400 bad request

As written in Guzzle official documentation: http://guzzle.readthedocs.org/en/latest/quickstart.html

A GuzzleHttp\Exception\ClientException is thrown for 400 level errors if the exceptions request option is set to true

For correct error handling I would use this code:

use GuzzleHttp\Client;
use GuzzleHttp\Exception\RequestException;

try {

    $response = $client->get(YOUR_URL, [
        'connect_timeout' => 10
    ]);
        
    // Here the code for successful request

} catch (RequestException $e) {

    // Catch all 4XX errors 
    
    // To catch exactly error 400 use 
    if ($e->hasResponse()){
        if ($e->getResponse()->getStatusCode() == '400') {
                echo "Got response 400";
        }
    }

    // You can check for whatever error status code you need 
    
} catch (\Exception $e) {

    // There was another exception.

}

GuzzleHttp\Client 400 bad request on Laravel 5.5

Try the below code:

$client = new \GuzzleHttp\Client(['headers' => ['Content-Type' => 'application/json',
                                                'apikey'=> config('app._api_key'),
                                                'debug' => true
                                                ]
                                ]);
$URI = 'http://api.example.com';
$body['sender']='Test_sender';
$body['recipient']=config('app.test_recipient');
$body['message_body']='Test  body';
$body=json_encode($body);
$URI_Response = $client->request('POST',$URI,['body'=>$body]);
$URI_Response =json_decode($URI_Response->getBody(), true);
return $URI_Response;

Note: I would suggest you to handle error please refer GuzzleDocumentation

Guzzle POST request always returns 400 Bad Request

If you're using Guzzle 6 (and you probably should be), you're actually constructing in a more complex way than you need to, such that the endpoint is not receiving the expected JSON. Try this instead:

$client = new Client([
     'base_uri' => 'https://my.endpoint.com/api',
     'headers' => [
          'Accept' => 'application/json',
          ...other headers...
     ]
]);

$data = [...your big slab of data...];

$response = $client->post('/kitely/path', ['json' => $data]);

// a string containing the results, which will depend on the endpoint
// the Accept header says we will accept json if it is available
// then we can use json_decode on the result
$result = $response->getBody()->getContents();  

Guzzle 400 Bad Request

You are sending two different requests. With JavaScript, you send the data as JSON in the request body. With Guzzle however, you're using form-params, which is a different format.

To fix this, just replace form-params key with json and remove "content-type"=>"application/x-www-form-urlencoded".

Guzzle Post Using API Key Keeps Resulting in 400 Bad Request

I was able to get this working. It looks like the ActiveMQ setup was expecting a JSON message when I'm trying to send an XML message.

I was able to determine this by turning on the Guzzle debug flag.

$client = new GuzzleHttp\Client([
    'debug'           => true
]);

Then adding the content-type to the headers.

'headers' => array(
    'apikey' => 'apikeyhere',
    'Content-Type' => 'application/xml',
)

Hope this helps someone in a similar boat.

Guzzle authentication returning 400 error

Working with:

$client = new \GuzzleHttp\Client();
              $url = "";
              $response = $client->request('POST', $url, [ 
                'headers' => [
                     'Accept' => 'application/x-www-form-urlencoded', 
                     'Authorization' => 'Basic $token'
                ],
                'form_params' => [
                     'grant_type' => 'password', 
                     'scope' => 'forintegration', 
                     'username' => '',
                     'password' => ''
                ] 
            ]);
            
              $body = $response->getBody();
              print_r(json_decode((string) $body));

GuzzleHttp - 400 error exception but with curl working perfectly

You need

'json' => $body

instead of

'form_params' => $body
