When encountering "Undefined property: $client" error, try to obtain information.

Question

I'm using Laravel v5.8 and guzzlehttp v7.4 and trying to write this controller to get some information:

public function __construct()
    {
        $client = new Client(['base_uri' => 'https://jsonplaceholder.typicode.com/']);
    }
    public function getInfo(Request $request)
    {
        try {
            $response = $this->client->request('GET', 'posts');
            
            dd($response->getContents());
        } catch (ClientException $e) {
            dd($e);
        
        }
    }

But when I call the getInfo method, I get the following error message:

Undefined property: App\Http\Controllers\Tavanmand\AppResultController::$client

However the documentation says to call the uri like this.

So what’s the problem here? How can I solve this problem?

Answer 1

Configure $client as a global variable of this class.

Then set the value in the constructor:

public $client
    public function __construct()
    {
        $this->client = new Client(['base_uri' => 'https://jsonplaceholder.typicode.com/']);
    }

Happy coding...

The scope of your $client variable is limited to inside the constructor. If you want to access it elsewhere, you need to assign it to some kind of class attribute;

private $client;
    
public function __construct()
{
    $this->client = new Client(['base_uri' => 'https://jsonplaceholder.typicode.com/']);
}

public function getInfo(Request $request)
{
    try {
        $response = $this->client->request('GET', 'posts');
    //...
}
