亲测有用。

php代码

$file = $_FILES['order_upload']['tmp_name'];
//            // var_dump($file);exit();
//            // 判断文件是否存在
            if (!file_exists($file)) {
                $this->show('文件不存在！');
                exit;
            }
            $params = [
                'file'=>new \CURLFILE($file),
                'id'=>'1',
                'fileName'=>$_FILES['order_upload']['name'],
            ];

            $url = "http://localhost:8080/upload";


            $header = array('Content-Type: multipart/form-data');

            $curl = curl_init();
            curl_setopt($curl, CURLOPT_URL, $url);
            curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");//3.请求方式
            curl_setopt($curl, CURLOPT_POSTFIELDS, $params);
            curl_setopt($curl, CURLOPT_HEADER, 0);
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($curl, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1);
            curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
            curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
            curl_setopt($curl,CURLOPT_HEADER,$header);
            $response = curl_exec($curl);

            echo $response;
