I use the Guzzle\Http library to be able to make requests to some urls with PHP.

I'm doing webservice with our systems, where, if the request is recognized as Ajax , the returned result is Json . Otherwise, HTML is returned.

However, I now need to make requests in those urls with Guzzle , and I want the request to be made by Guzzle , so I'm also returned in Json .

How to make requests with the Guzzle\Http library, as if it were AJAX executed by a browser?

Do I need to put some or some headers to work?

php guzzle

Actually, there is no way to detect if it is real ajax (and this is what helps us), what we do is send a header that uses the prefix x- , usually in HTTP use of this prefix means experimental.

X-Requested-With: XMLHttpRequest

It does not mean that it is Ajax, it actually means that it is XmlHttpRequest (as explained here Ajax is not a language So what is it? )

In case we detect if the submission is XMLHttpRequest , in XMLHttpRequest you can define in the instance of Guzzle\Http , to "inherit" the settings in other requests. This simplifies the configuration:

  $client = new Guzzle\Http(['headers' => ['X-Request-With' => 'XMLHttpRequest']]);

  $client->put(/** **/);

  $client->post(/** **/);

  $client->get(/** **/);

Or using Guzzle\Http like this:

$client = new GuzzleHttp\Client(...);

$client->request('GET', '/caminho/foo/bar/baz', [
    'headers' => ['X-Requested-With' => 'XMLHttpRequest']
]);

Just an additional framework, such as Laravel and cakephp, use these methods to detect if it has the header GuzzleHttp\Client :

Laravel:

public function index(Request $request)
{
    if($request->ajax()){

cakephp:
```
if ($this->request->is('ajax')) {
```
