php7 curl上传文件

Question

php7使用curl上传文件返回错误码26；代码如下：

    $size    =    filesize($path);//文件大小
    $ch = curl_init($url);
    $cfile = curl_file_create($path);
    if (is_null($post_data)) {
        $data = array('media' => $cfile);
    }else{
        $data = array('media' => $cfile,'description'=>$post_data);
    }
    curl_setopt($ch, CURLOPT_POST,1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_INFILESIZE,$size);
    curl_setopt($ch, CURLOPT_HEADER, 0); // 显示返回的Header区域内容
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 获取的信息以文件流的形式返回
    $info    =    curl_exec($ch);
    if (curl_errno($ch)) {
        var_dump(curl_errno($ch));
        return FALSE;
    }
    curl_close($ch); // 关闭CURL会话
    return $info; // 返回数据

我查看手册后使用过CURLFile函数，但返回的错误依然是26错误码，或者是缺少多媒体问题等

    $cfile  =   new \CURLFile($path,$upload_type,$upload_name);

php版本

• <=5.4 curl上传文件只支持@语法

• = 5.5 支持@语法和CURLFile类

• 大于=5.6 只支持CURLFile类

// 兼容性写法参考示例

        $curl = curl_init();
        
        if (class_exists('\CURLFile')) {// 这里用特性检测判断php版本
            curl_setopt($curl, CURLOPT_SAFE_UPLOAD, true);
               $data = array('file' => new \CURLFile(realpath($source)));//>=5.5
        } else {
            if (defined('CURLOPT_SAFE_UPLOAD')) {
                curl_setopt($curl, CURLOPT_SAFE_UPLOAD, false);
            }
            $data = array('file' => '@' . realpath($source));//<=5.5
        }
        
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_POST, 1 );
        curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curl, CURLOPT_USERAGENT,"TEST");
        $result = curl_exec($curl);
        $error = curl_error($curl);
