php thinkphp 抖音支付，订单同步接口分享

1. 抖音支付

需要获取抖音小程序的AppID,AppSecret,需要配置回调地址，Token获取SALT
官方地址：支付，订单同步

以下干货仅针对于有一定开发基础的精英，0基础的止步。

  public function DouyinPay($openId='',$id='',$body = '抖音担保支付'){

        $order=db('order')->where(['id'=>$id,'status'=>1])->find();//获取订单信息

        $outOrderNo = $order['orderno'];//开发者侧的订单号
        $totalAmount = $order['price'];//支付价格; 接口中参数支付金额单位为[分]
        $subject = "订单号：".$order['orderno']; //商品描述也就是标题
        $body = $body;
        $validTimestamp = 60 * 60;//订单过期时间(秒);
        $notifyUrl = "https://***/notify"; //这里可以忽略，走字节跳动小程序 -支付 -担保配置-设置回调地址
        //创建订单
        $response = $this->createOrder($outOrderNo, $totalAmount, $subject, $body, $validTimestamp, $notifyUrl);

        $this->success('成功',$response);

不要单纯以为只要支付完成就OK了，下面还需要订单同步到抖音，下场如下

2.订单同步

这里不需要申请额外的参数，大致分为三步（1.获取token，2.组装商品，3.组装订单）
代码如下：

     /**
     * 订单推送到抖音
     * @param $data array 订单数据
     * @note order_status 与 status须保持一致,但类型不同
     * @return array
     */
    public  function pushOrder($id=''){
        $data=[];//获取订单信息
        $api = "https://developer.toutiao.com/api/apps/order/v2/push";
        $openid ='';//获取下单用户openid
  		//组装商品
        $item_list = [['item_code' => '购买会员卡','img'=>'https://***/logo.jpg',
            'title'=>'会员服务','amount'=>1,'price'=>(int)($data['price']*100)]];//参数对应请查看官方文档，注意字段类型
           // 组装订单
        $detail = [
            'order_id'=>$data['orderno'],'create_time'=>strtotime($data['add_time'])*1000,'status'=>"已支付",'amount'=>1,
            'total_price'=>(int)($data['price']*100),'detail_url'=>"pages/me/vip/vip",'item_list'=>$item_list];
              dump($detail);
              
        $param = ['access_token'=>$this->getAccessTokens(),'app_name'=>"douyin",
            'open_id'=>$openid,'update_time'=>$this->getMillisecond(),'order_detail'=>json_encode($detail),'order_type'=>0,'order_status'=>1,'payment_order_no'=>$data['orderno']];
     
        $result =$this->posts($api,$param);//请求
      
    }
     /**
     * 获取AccessToken
     */
    public  function getAccessTokens(){
        $api = "https://developer.toutiao.com/api/apps/v2/token";
			  $param = ['appid'=>'***','secret'=>'***','grant_type'=>"client_credential"];
        $access_token = Cache::get('dy_accessToken');
        if(empty($access_token)){
            $data = $this->posts($api,$param);
         //   dump($result);die;
         //   $data = json_decode($result,true);
            if($data['err_no'] == 0){
                $access_token = $data['data']['access_token'];
                Cache::set('dy_accessToken',$access_token,$data['data']['expires_in']);
            }
        }
        return $access_token;
    }
       public  function getMillisecond() {
        list($t1, $t2) = explode(' ', microtime());
        return (float)sprintf('%.0f',(floatval($t1)+floatval($t2))*1000);
    }
