CodeIgniter GuzzleHttp 403 禁止答案

【问题描述】：

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并且它们都运行良好）。我已经使用 Postman 测试了 API，它工作得很好，但是当我尝试使用我的客户端应用程序（使用 GuzzleHttp v6.5.5）访问 API 时，我不断收到 403 Forbidden 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); 
    }
?>

我尝试在标头中使用 User-Agent、Accept 和 Accept-Encoding，但仍然收到 403 Forbidden 错误。我在代码中做错了什么？提前致谢。

更新：回应@Ivan Ivanov 的评论；在我将“body”更改为“json”之后，当我运行它而不是 403 时，系统现在给我 500 内部服务器错误。但是话又说回来，如果我尝试通过邮递员登录它就可以了。

另外，$this->_client 似乎不为空。

标签： php codeigniter cpanel guzzle

【解决方案1】：

你应该改变这一行：

'body' => json_encode($params)

用这个：

'json' => json_encode($params)

因为Guzzle 期望'json' key 在POST array 中。

还有var_dump( $this->_client ) 看看你有没有客户。
