unexpected 'use' (T_USE) when trying to use composer

问题

So, I am trying to use the coinbase API. I'm attempting a simple test to see if I can make it work, but I'm getting various composer errors.

Currently, I am getting unexpected t 'use' for this code:

            use Coinbase\Wallet\Client;
            use Coinbase\Wallet\Configuration;

            $apiKey = 'public';
            $apiSecret = 'private';
            $configuration = Configuration::apiKey($apiKey, $apiSecret);
            $client = Client::create($configuration);
            $spotPrice = $client->getSpotPrice();
            echo $spotPrice;

So, are my use statements in the wrong place? Ive tried them outside the index function and outside the class. Both yield completely different sets of results than this.

Outside of the Keks class, I get

Fatal error: Class 'Coinbase\Wallet\Configuration' not found in /home/content/61/11420661/html/beta/application/controllers/keks.php on line 15

And inside the class but outside the index() function I get

Fatal error: Trait 'Coinbase\Wallet\Client' not found in >/home/content/61/11420661/html/beta/application/controllers/keks.php on line 4

Is there something wrong in my composer.json maybe?

回答1:

You cannot use "use" where you are using it.

The "use" keyword is either in front of a class definition to import other classes/interfaces/traits into it's own namespace, or it is inside the class (but not inside a method) to add traits to the class.

<?php
namespace Foo;

use Different\Class; // use can go here

class Bar {
  use TraitCode; // use can go here

  public function baz() {
    $this->traitFunction('etc');
    // use CANNOT go here
  }
}

I'm using codeigniter when i try to use "use" keyword its throwing error within a method.

SO i just moved it to above class declaration.

<?php
  defined('BASEPATH') OR exit('No direct script access allowed');
  use Auth0\SDK\Auth0;

  class Home extends CI_Controller {

  }
?>

Its working fine.
