PHP1.0版本上传OSS报错，大家帮忙解决下啊

代码如下：

        $oss_sdk_service = new ALIOSS();    
        $oss_sdk_service->set_debug_mode(FALSE);        
        
        $bucket = 'xxxx';
        $object = 'oss-file-name-'.time().'.jpg';    
        
        $pathFile = "C:/1.jpg";        
    
        $upload_file_options = array(
            'content' => fopen($pathFile, 'r'),
            'length' => filesize($pathFile),
        );        
        $upload_file_by_content = $oss_sdk_service->upload_file_by_content($bucket,$object,$upload_file_options);
        print_r($upload_file_by_content);die();


然后报错：
exception 'OSS_Exception' with message 'Http Body的内容非法'，截图如下：



但是采用upload_file_by_file上传是可以的，可是项目需要采用binary的上传方式， 请大家帮我看看是怎么回事，谢谢
