Laravel 使用 EasySms 发送阿里云短信报错：All the gateways have failed.

感谢关注这个问题～
我已经排除了签名、模板、accesskey以及阿里云格式的不对，阿里云的“发送量统计”与“发送记录查询”也没有看到任何记录。

config/easysms.php配置文件：

<?php
return [
    // HTTP 请求的超时时间（秒）
    'timeout' => 5.0,

    // 默认发送配置
    'default' => [
        // 网关调用策略，默认：顺序调用
        'strategy' => \Overtrue\EasySms\Strategies\OrderStrategy::class,

        // 默认可用的发送网关
        'gateways' => [
            'aliyun'
        ],
    ],
    // 可用的网关配置
    'gateways' => [
        'errorlog' => [
            'file' => '/tmp/easy-sms.log',
        ],
        'aliyun' => [
            'access_key_id' => env('ALIYUN_ACCESSKEY_ID'),
            'access_key_secret' => env('ALIYUN_ACCESSKEY_SECRET'),
            'sign_name' => env('ALIYUN_SMS_SIGN_NAME'),
        ]
    ],
];

EasySms注册器：

<?php
namespace App\Providers;
use Overtrue\EasySms\EasySms;
use Illuminate\Support\ServiceProvider;

class EasySmsServiceProvider extends ServiceProvider
{
    public function register()
    {
        //
    }
    public function boot()
    {
        $this->app->singleton(EasySms::class, function ($app) {
            return new EasySms(config('easysms'));
        });

        $this->app->alias(EasySms::class, 'easysms');
    }
}

config/app.php文件的provider中添加：

App\Providers\EasySmsServiceProvider::class

.env文件：

ALIYUN_ACCESSKEY_ID=************************
ALIYUN_ACCESSKEY_SECRET=****************************
ALIYUN_SMS_SIGN_NAME=博客

控制器：

<?php
namespace App\Http\Controllers;

use Overtrue\EasySms\EasySms;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;

class SmsController extends Controller
{
    public function send(Request $request,EasySms $easySms){
        $phone = '182********';
        $code = 123456;
        try {
            $result = $easySms->send($phone, [
                'template' => 'SMS_********',
                'data' => [
                    'code' => $code,
                ],
            ]);
            echo $result;
        } catch (\GuzzleHttp\Exception\ClientException $exception) {
            $response = $exception->getResponse();
            $result = json_decode($response->getBody()->getContents(), true);
        }
    }
}

报错如下：
