Php 禁止使用CodeIgniter Guzzle HTTP 403

所以我创建了2个CodeIgniter应用程序；一个应用程序是API，另一个是客户端应用程序。我已经在cPanel中部署了这两个应用程序（在部署之前，我已经测试了这两个应用程序，它们都可以正常工作）。我已经使用Postman测试了API，它运行得很好，但是当我尝试使用我的客户端应用程序（使用GuzzleHTTPV6.5.5）访问API时，我一直收到403禁止的错误

控制器：

public function login() 
    {
        if (isset($this->session->token)) {
            $this->session->set_flashdata('danger', 'You are logged in.');

            redirect(base_url('main/page_login'));
        }

        $input = $this->input->post(null, TRUE);

        $response = $this->main_model->login($input);
        if ($response['status'] != 200) {
            $this->session->set_flashdata('danger', $response['message']);

            redirect(base_url('main/page_login'));
        } 

        $response['user']['full_name'] = $response['user']['first_name'] . ' ' . $response['user']['last_name'];
        $this->session->set_userdata('user', $response['user']);
        $this->session->set_userdata('roles', $response['id_roles']);
        $this->session->set_userdata('token', $response['token']);
        $this->session->set_userdata('is_admin', FALSE);

        foreach ($this->session->roles as $roles) {
            if (in_array($roles['id_role'], array(1, 2))) {
                $this->session->is_admin = TRUE;
            }
        }

        $this->session->set_flashdata('login', 'Logged in');

        if ($this->session->flashdata('referrer') != '') {
            redirect(base_url($this->session->flashdata('referrer')));
        } else {
            redirect(base_url('main'));
        }
    }

型号：

<?php
  //Guzzle configuration
  use GuzzleHttp\Client;

    class Main_model extends CI_Model{

    private $_client;
    private $_base_uri;

    public function __construct()
    {
        $this->_client         = new Client();
        $this->_client_service = 'frontend-client';
        $this->_auth_key       = 'rest-api';
        $this->_base_uri       = 'https://myapp.com/api';
    }

    function login($params) 
    {
        $response = $this->_client->request('POST', $this->_base_uri . '/auth/login', [
          'headers' => [
              'Client-Service' => $this->_client_service,
              'Auth-Key'       => $this->_auth_key
          ],
          'body' => json_encode($params)
        ]);

        return json_decode($response->getBody()->getContents(), true); 
    }
?>

我已经尝试在头中使用用户代理、接受和接受编码，但仍然得到403禁止的错误。我在代码中做错了什么？提前谢谢

更新： 回应@Ivan Ivanov的评论；在我将“body”改为“json”后，当我运行它而不是403时，系统现在给我500个内部服务器错误。但话说回来，如果我试着通过邮递员登录，效果会很好

您应该更改此行：

'body' => json_encode($params)

为此：

'json' => json_encode($params)

因为

Guzzle

需要

POST数组中的
'json'键

还有
var\u dump（$this->\u client）
看看你是否有客户。
我已经更新了关于你评论的帖子，先生。
'body' => json_encode($params)

'json' => json_encode($params)
