    /**
     * 生成授权链接
     * @param string $redirect_uri
     * @return string
     */
    public function getAuthUrl($redirect_uri,$app_id) {
        $this->redirect_uri = $redirect_uri;
        $randomn = $this->generateRandomString(48);
        $appmodel = new MercadolibreAPP();
        $appmodel->updateAll(['code_verifier'=>$randomn],"id=".$app_id);//产生的随机数记录到数据库

        $encoded = base64_encode(hash('sha256', $randomn, true));//code_verifier经过sha256
        $code_challenge = strtr(rtrim($encoded, '='), '+/', '-_');//整理 得到 code_challenge

        $params = array("client_id" => $this->client_id, "response_type" => "code", "redirect_uri" => $redirect_uri,'code_challenge'=>$code_challenge,'code_challenge_method'=>'S256');
        if(in_array($this->client_id,[8274783443247575,8149149353703108,2401922632679187,6739263324786978,878999950093151,2621145909128904,4224821929868485,4367955135326677])){ //本土账号测试
            return 'https://auth.mercadolibre.com.mx/authorization?'.http_build_query($params);
        }
        return 'https://global-selling.mercadolibre.com/authorization?'.http_build_query($params);
      //  return $this->request_url."/merchant/authorization?".http_build_query($params);
    }
    //生成随机数
    public function generateRandomString($length = 48) {
        $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
        $randomString = '';
        for ($i = 0; $i < $length; $i++) {
            $randomString .= $characters[rand(0, strlen($characters) - 1)];
        }
        return $randomString;//随机字符串
    }

上述会得到授权的链接例如：

https://auth.mercadolibre.com.mx/authorization?client_id=4367955135326677&response_type=code&redirect_uri=https%3A%2F%2Fpublish.xxxxxxxx.com%2Findex.php%2Fservices%2Fmercadolibre%2Fmercadolibreauthorize%2Faccept%2Fstate%2F61&code_challenge=Xgemq5fLBSsZAe3dl2KteKYPg_AJja_0rrcGxNbbH_g&code_challenge_method=S256

里面多了两个参数 code_challenge：随机数(code_verifier)进过 sha256 加密的参数

根据返回的code得到token:

public function authorize($code, $redirect_uri,$account_id) {

        if($redirect_uri)
            $this->redirect_uri = $redirect_uri;

        $body = array(
            "grant_type" => "authorization_code",
            "client_id" => $this->client_id,
            "client_secret" => $this->client_secret,
            "code" => $code,
            "redirect_uri" => $this->redirect_uri.'/state/'.$account_id,
            'code_verifier' =>$this->code_verifier //这里是生成授权链接的时候产生的随机数
        );
        $opts = array(
            CURLOPT_POST => true,
            CURLOPT_POSTFIELDS => $body
        );

        $request = $this->execute(self::$OAUTH_URL, $opts);

        if($request["httpCode"] == 200) {
            $this->access_token = $request["body"]->access_token;

            if($request["body"]->refresh_token)
                $this->refresh_token = $request["body"]->refresh_token;

            return $request;

        } else {
            return $request;
        }
    }

促销活动

    /**
     * 获取user下面的活动
     */
    public function getuserpromotion($user_id,$token){
        return $this->api()->get('/marketplace/seller-promotions/users/'.$user_id,['access_token' => $token ]);
    }

结果：

    /**
     * 获取产品的详细信息
     */
    public function get_one_listing($mpid,$token)
    {
        return $this->api()->get('/marketplace/items/'.$mpid,['access_token' => $token ]);
    }

结果

    /**
     * 获取产品参加的促销活动
     */
    public function checkpromotion($item_id,$user_id,$token){
        return $this->api()->get('/marketplace/seller-promotions/items/'.$item_id,['user_id'=>$user_id,'access_token' => $token ]);
    }

结果：

Array
(
    [body] => Array
        (
            [0] => stdClass Object
                (
                    [id] => MLM28447
                    [type] => DEAL
                    [status] => pending
                    [start_date] => 2023-03-06T00:00:00-06:00
                    [finish_date] => 2023-04-03T13:00:00-05:00
                    [deadline_date] => 2023-03-18T05:00:00Z
                    [name] => nueva temporada primavera
                )

            [1] => stdClass Object
                (
                    [id] => MLM20378
                    [type] => DEAL
                    [status] => started
                    [start_date] => 2022-06-17T12:00:00-05:00
                    [finish_date] => 2030-12-31T22:59:00-06:00
                    [name] => New Sellers ramp up
                )

            [2] => stdClass Object
                (
                    [id] => 
                    [type] => PRICE_DISCOUNT
                    [status] => candidate
                    [start_date] => 
                    [finish_date] => 
                )

        )

    [httpCode] => 200
)

    /**
     * 获取促销活动下面的产品
     */
    public function getpromotionitem($user_id,$deal_id,$token){
        return $this->api()->get('/marketplace/seller-promotions/promotions/'.$deal_id.'/items',['user_id'=>$user_id,'access_token' => $token ]);
    }

结果：

修改促销价格和成本价格其中的deal_id 获得的状态必须是 [status] => started 对于 [status] => pending和[status] => candidate 无效

$data = ['deal_id'=>'MLM1029','regular_price'=>12,'deal_price'=>10.98,'promotion_type'=>'DEAL'];
/**
  * 修改促销价格和成本价格
*/
public function addpromotion($item_id,$user_id,$data,$token){
    return $this->api()->post('/marketplace/seller-promotions/items/'.$item_id,$data,['user_id'=>$user_id,'access_token' => $token ]);
}
