php - 代码点火器 : Sendmail cannot use Mailgun\Mailgun - it is not a trait Composer

Question

我尝试用图书馆发送电子邮件Mailgun在 Codeigniter 中使用 composer 安装。我收到一些错误:

Fatal error: Sendmail cannot use Mailgun\Mailgun - it is not a trait in C:\xampp\htdocs\ngetest\application\controllers\Sendmail.php on line 4
A PHP Error was encountered
Severity: Error

Message: Sendmail cannot use Mailgun\Mailgun - it is not a trait

Filename: controllers/Sendmail.php

Line Number: 4

Backtrace:

我不知道为什么会出现此错误，我已经关注文档 mailgun 并观看了 youtube，但仍然出现此错误。

我的配置 Codeigniter 是:

我的 Sendmail Controller

<?php
class Sendmail extends CI_Controller
{
    use Mailgun\Mailgun;
    public function __construct()
    {   
        parent::__construct();
        # Include the Autoloader (see "Libraries" for install instructions)
        // require  FCPATH . './vendor/autoload.php';
    }
    public function index()
    {

        try {
            # Instantiate the client.
            $mgClient = new Mailgun('1xxxx');
            $domain = "xxx.mailgun.org";
            # Make the call to the client.
            $result = $mgClient->sendMessage($domain, array(
                'from'  => 'Excited User <mailgun@YOUR_DOMAIN_NAME>',
                'to'    => 'Baz <YOU@YOUR_DOMAIN_NAME>',
                'subject' => 'Hello',
                'text'  => 'Testing some Mailgun awesomness!'
            ));
            return $result;
        } catch (\Throwable $th) {
            echo ' $th';
        }
    }
}

Answer 1

我认为问题出在您的use Mailgun\Mailgun;。这必须在文件的开头，在您声明类之前:

<?php

use Mailgun\Mailgun;

class Sendmail extends CI_Controller
{
    ...

类内的 use 与类外的处理方式不同。
