前提條件

• 已準備專案appkey，詳情請參見創建專案，

• 已獲取Access Token，詳情請參見獲取Token，

獲取token前提條件

• 已獲取AccessKey ID和AccessKey Secret，詳情請參見開通服務，

獲取Token代碼：

     /**
     * 獲取Token
     * @return int|mixed|string
     * @throws ClientException
     */
    public function getToken(){
        $cacheToken = cache('AccessToken');
        if ($cacheToken) return $cacheToken;
        AlibabaCloud::accessKeyClient(
            config('aliyun.accessKeyId'), //你的阿里云accessKeyId
            config('aliyun.accessKeySecret') //你的阿里云accessKeySecret
        )
            ->regionId("cn-shanghai")
            ->asDefaultClient();
        try {
            $response = AlibabaCloud::nlsCloudMeta()
                ->v20180518()
                ->createToken()
                ->request();
            $token = $response["Token"];
            if($token) {
                cache('AccessToken',$response["Token"]['Id'],3600);    //存快取
                return $response["Token"]['Id'];  //Token在此
            }
            return 0;
        } catch (ClientException $exception) {
            // 獲取錯誤訊息
            return $exception->getErrorMessage();
        } catch (ServerException $exception) {
            // 獲取錯誤訊息
            return $exception->getErrorMessage();
        }
    }

控制器代碼：

<?php

namespace app\index\controller;

use app\index\model\Index as I;
class Index extends Base
{
    public function index()
    {
        $data = (new I())->index();
        $this->assign('file', $data);
        return $this->fetch();
    }
}

模型代碼：

public function index(){

        $text = input('post.text');
        $appkey = config('aliyun.appKey'); //專案AppKey
        $token = $this->getToken();
        $audioSaveFile = date('YmdHis').".wav"; //檔案名
        $format = "wav";    
        $sampleRate = 16000;
        $res = $this->processPOSTRequest($appkey, $token, $text, $audioSaveFile, $format, $sampleRate);
        return ($res);
    }

    public function processPOSTRequest($appkey, $token, $text, $audioSaveFile, $format, $sampleRate)
    {
        $url = "nls-gateway.cn-shanghai.aliyuncs.com/stream/v1/tts";

            // voice 發音人，可選，默認是xiaoyun，
             "voice" => "Aida",
