php调用接口： 通过post提交请求

    function request_post($url = '', $param = '') {
        if (empty($url) || empty($param)) {
            return false;
        }
         
        $postUrl = $url;
        $curlPost = $param;
        $ch = curl_init(); 
        curl_setopt($ch, CURLOPT_URL,$postUrl); 
        curl_setopt($ch, CURLOPT_HEADER, 0); 
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
        curl_setopt($ch, CURLOPT_POST, 1); 
        curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);
        $data = curl_exec($ch); 
        curl_close($ch);
        return $data;
    }

     public function send(){
             //请求地址
            $sUrl = 'http://xxxxxxxxxxx.com/addOrders';
            $aData = array(
                'order_id'=>$order_id,//预约号
                'point'=>$data['collection_point'],//采集点
                'name'=>$name,//姓名
                
            );
            $sResult = $this->request_post($sUrl, $aData);
            dump($sResult );
