首先下载

安装阿里云短信SDK

composer require alibabacloud/sdk

安装 Alibaba Cloud SDK for PHP 作为依赖项

composer require alibabacloud/darabonba-openapi

最后安装对应的包

composer require alibabacloud/dysmsapi-20170525 

上面3个都下载了，官方网站并没有说明下载sdk，这个没有下载，查询资料花了几个小时，掉坑了

这里要添加配制文件信息，阿里云的信息，包含短信的信息等。自行准备 

<?php
namespace services\alisms;
use AlibabaCloud\Client\AlibabaCloud;
use AlibabaCloud\Client\Exception\ClientException;
use AlibabaCloud\Client\Exception\ServerException;
class AliSmsService
{
    /**
     * 阿里云发送短信
     * @param string $phone
     * @param int $code
     * @return bool
     * @throws ClientException
     */
    public static function sendCodeServer(string $phone, int $code) : bool {
        if(empty($phone) || empty($code)){
            return false;
        }
        AlibabaCloud::accessKeyClient(config("aliyun.access_key_id"), config("aliyun.access_secret"))
            ->regionId(config("aliyun.region_id"))
            ->asDefaultClient();
        $templateParam = [
            "code" => $code
        ];
        try {
            $result = AlibabaCloud::rpc()
                ->product('Dysmsapi')
                // ->scheme('https') // https | http
                ->version('2017-05-25')
                ->action('SendSms')
                ->method('POST')
                ->host(config("aliyun.host"))
                ->options([
                    'query' => [
                        'RegionId' => config("aliyun.region_id"),
                        'PhoneNumbers' => $phone,
                        'SignName' => config("aliyun.sign_name"),
                        'TemplateCode' => config("aliyun.template_code"),
                        'TemplateParam' => json_encode($templateParam),
                    ],
                ])
                ->request();
//            print_r($result->toArray());
        } catch (ClientException $e) {
            return false;
            // echo $e->getErrorMessage() . PHP_EOL;
        } catch (ServerException $e) {
            return false;
            // echo $e->getErrorMessage() . PHP_EOL;
        }
        return true;
    }


      function sendCode( string  $phone) : bool {
        $code = rand(100000, 999999);
        $sms = self::sendCodeServer($phone, $code);
        if($sms){
            // 需要记录redis及失效时间1分钟
        }
        return true;
    }


}

这是控制器代码 

<?php


namespace app\api\controller;

/**
 * 发送短信
 * Class Code
 * @package app\api\controller
 */
use services\alisms\AliSmsService;
class Code
{

    public function send_code(){

        $phone=input('phone');
        if (empty($phone)){
            return error_json('手机号码不能为空');
        }
        /*try {
            validate(User::class)->scene("send_code")->check($data);
        }catch (ValidateException $e){
            return show(config("status.error"), $e->getError());
        }*/
        if($this->getAliSmsService()->sendCode($phone)){
            return success_json("发送验证码成功");
        }
        return error_json("发送验证码失败");
    }

    function getAliSmsService(){
        return app(AliSmsService::class);
    }


}

bug

部署到服务器上的阿里云SDK会报错，如下

这是报错信息 Class 'AlibabaCloud\Client\AlibabaCloud' not found  代码里已经引用了，但是会报错，测试发现，原来是阿里云SDK造成的，昨天修复好了，第二天又出现同样的问题，我先把解决方法给大家看一看

 代码中引用的，如图下

解决方案如下，直接更新阿里云SDK

需要用composer安装

1.切换阿里云镜像

composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

2.安装阿里云SDK

composer require alibabacloud/sdk
